Re: [PHP-DB] One query, different tables?
Hello. I am newbie in this and need som basic help. I have a form witch checkbox'es with different serialnumbers. The serialnumbers reflect different products and every product category have their own tables. This sounds like a database design question more than a PHP one. I can transfer items from store to truck but can't transfer them back to store. I have 4 stores and like to transfer products between this. I like to to it like this: store_one - truck_document - store_two But how can I transfer both Dynamite and Exan in one query to their respective tables? (One table is named exan and the other dynamite.) Thank you very much for your help. I have been searching google but can't find anything about this question.

Re: [PHP-DB] PDO Exceptions
Greetings, I am new to this list. I have a question about which functions need to be included in a try block. Of new PDO, prepare, bindParam, execute, fetch, and query, it seems that bindParam is the only one that throws an exception. So is this the only that needs to be put into a try block? Thanks, -KJW Proverbs 3:5-6 Are you aware that there is a setting to control whether PDO objects throw exceptions, warnings, or nothing?

Re: [PHP-DB] Activating the mysql_clear_password plugin
Hi everyone, I need to use the mysql_clear_password plugin. I'm using the CentOS php 5.3.3 and manually recompiled the mysql mysqli extensions with the Oracle MySQL 5.5 libraries. According to the MySQL documentation ( http://dev.mysql.com/doc/refman/5.5/en/cleartext-authentication-plugin.html), I need to either set the LIBMYSQL_ENABLE_CLEARTEXT_PLUGIN or set the MYSQL_ENABLE_CLEARTEXT_PLUGIN option to the mysql client. I tried to set the LIBMYSQL_ENABLE_CLEARTEXT_PLUGIN via a SetEnv in Apache with no results. The SetEnv directive sets variables for Apache's internal environment.the I believe the MySQL docs are refering to the Operating System's environment, which would set this globally for the MyQL server. This is probably not what you want to do as you appear to be trying to do this per connection. You could try using mysqli_options(), but I do not know if that supports this setting yet. The PHP documentation does not mention it, and I am unable to test it myself at the moment. Could anyone help me setting the MYSQL_ENABLE_CLEARTEXT_PLUGIN option to the mysql client ?

Hi You could try using mysqli_options(), but I do not know if that supports this setting yet. The PHP documentation does not mention it, and I am unable to test it myself at the moment. Just occured to me, even if the setting is not directly supported yet, you can create a separate configuration file for this setting the client to use the plugin (enable-cleartext-plugin) then: mysqli_options(MYSQLI_READ_DEFAULT_FILE,'myother.cnf'); to use those settings on the connection. -- Niel Archer niel.archer (at) blueyonder.co.uk -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] Receiving Error- Error: user account already exists..
I keep receiving the following error..( Error: user account already exists..
) although I don't have any data in my table. Any help would be appreciated.
The code follows:
?php
session_start();
include ('dbc.php');
if (isset($_POST['Submit']) =='Register')
As Jim already pointed out, if $_POST['Submit'] is set to ANY value this
check will be true. I think you want something like :
if (isset($_POST['Submit']) $_POST['Submit'] =='Register')
{
if (strlen($_POST['email']) 5)
{
die (Incorrect email. Please enter valid email address..);
}
if (strcmp(isset($_POST['pass1']),isset($_POST['pass2'])) ||
empty($_POST['pass1']) )
{
//die (Password does not match);
die(ERROR: Password does not match or empty..);
}
if (strcmp(md5($_POST['user_code']),$_SESSION['ckey']))
{
die(Invalid code entered.
Please enter the correct code as shown in the Image);
}
$rs_duplicates = mysql_query(select id from users where
user_email='$_POST[email]');
You should test $rs_duplicates !== false to be sure you have a valid
resource.
Have you tried retrieving the supposed row(s) and var_dump-ing them to
see what it thinks they are? My guess is, you're getting an error
message, which is why there is a row to be counted. You can't use an
array inside a double-quoted string like that, change it to be wrapped
in braces like:
$rs_duplicates = mysql_query(select id from users where user_email='
{$_POST[email]}');

Re: [PHP-DB] problem in connecting to mysql from php
Hello everyone,
I am in the process of learning php and I was trying to connect to a mysql
database on my own computer(localhost). I have done the following as
prerequisites:
copied the dll files in system32
removed the semicolon(;) from extension=php_mysqli.dll
You should NOT need to move the .dll at all. There is a
setting in the ini which tells PHP where to look for extensions and that
should have pointed to the original location. Hence, removing the
semicolon should be the only part necessary.
In spite of doing the above when I try to run the following :
?php
$db = new MySQLi('localhost', 'root', 'Password123', 'test');
$sql = 'SELECT * FROM a123';
$result = $db-query($sql);
while($row = $result-fetch_object()) {
echo 'div' . $row-name . '/div';
}
$db-close();
?
I get the error: *Fatal error*: Class 'MySQLi' not found in *C:\Program
Files\Apache Software Foundation\Apache2.2\htdocs\a.php* on line *2
*Please guide me as to how can I get rid of this error?

You Selected Market = MCI

and Cell_Sect = '$cat' and Date = '$subcat' LIMIT 10);

Re: [PHP-DB] Re: Word Activity Application
The FOREACH below is giving me the error:
Invalid argument supplied for foreach()
Not surprising as the $match_words will contain a boolean result from
shuffle. Shuffle works directly on the variable it is given and returns
true or false, depending on success. rtfm ;-)
Does anyone understand what I have done to cause this error?
#query for words
$query =
SELECT `reference` , `word` , `explanation`
FROM `Bible_dictionary`
WHERE `live` =1
ORDER BY RAND( )
LIMIT 5
;
$words_match_up_result=mysql_query($query);
$records_found=mysql_numrows($words_match_up_result);
echo $records_found . br; # output is 5
#create array from mySQL query
$words = array();
$explanations = array();
$i=1;
while ( $i = $records_found ) {
$words[$i] = stripslashes( mysql_result($words_match_up_result,($i
-1),word) );
$explanations[$i] = stripslashes( mysql_result($words_match_up_result,($i
-1),explanation) );
++$i;
}
#shuffle arrays
$match_words = shuffle ( $words );
$match_explanations = shuffle ( $explanations );
change to:
$match_words = $words;
shuffle($match_words);
$match_explanations = $explanations;
shuffle($match_explanations);
However if these need to stay in sync this will not work. i.e if a
explanation's index needs to match the corresponding word's index, then
you'll have to do this another way. But as I understand your need here,
this isn't a problem?
#display words on the screen
foreach($match_words as $word) {
echo $word . br /\r\n;

I want to display 5 words on the left hand side and the 5 definitions on the

Should I use PHP to display the definitions in random order? OR Is there a

Re: [PHP-DB] If condition in query
Dear list -
Thank you for all your excellent help.
I wish to search a table. In this case, I have five(5) columns:
site, Record, BMI, Weight and Height.
I wish to be able to search on one or more of the columns. If I use
a query like:
$ste = $_POST['site'];
$req = $_POST['Record'];
$wgt = $_POST['Weight'];
$hgt = $_POST['Height'];
$bmi = $_POST['BMI'];
$sql1 = select * from intake2 where site = '$ste' Weight =
'$wgt' Record = '$req' '$hgt' = Height '$bmi' = BMI ;
$result = mysqli_query($cxn, $sql1);
and do not use all the variables, no data is returned. I use to
extract the data from the query.
while($row = mysqli_fetch_array($result[0]))
{
$site2 = $row[0];
$record2 = $row[1];
$bmi2 = $row[2];
$wgt2 = $row[3];
$hgt2 = $row[4];
printf(%s\t%d\t%3.1f\t%d\t%dbr /, $site2, $record2,
$bmi2, $wgt2, $hgt2);
}
If I put an extra test in the query to exclude blank values;eg,
(if(isset ($bmi) '$bmi' = BMI ), $result defaults to a boolean
and mysqli_fetch_array($result) fails. I wish to be able to search
on one or more, but not necessarily all, of the parameters and be
able to output the results.
Advice and help please.
Thanks in advance.
Ethan
First you need to protect your input from injection and other attacks.
http://en.wikipedia.org/wiki/SQL_injection
for the problem you ask, I'd suggest building the query in php rather
than SQL A simple example would be:
$where ' ';
if (isset($ste)) {
$where .= site = '$ste';
}
if (isset($wgt)) {
$where .= , Weight = '$wgt';
}
$sql .= WHERE $where;

Re: [PHP-DB] query help
Hello PHP Gurus, I need your help on an insert query. I wanted to know if there is way to insert an array of values into a DB. An eg would explain this better : If I have 2 tables in a DB, 1) users has 3 columns 2) hobbies = 5 columns I was thinking of having a single function which will perform the insert on any insert which happens on the entire website. Eg : This function can be called with 2 parameters, the first parameter the table name, and the second parameter is an array of values which will be inserted into the table. eg : Users has these columns [1]ID [2] Name [3]Location so the function call would be something like * insert_into_tbale(users,array[user_values])* ** Does this make sense ?

Re: [PHP-DB] Stuck in apostrophe hell
Before I send the following SQL to MySQL from PHP I print it to screen.
PHP chokes on it, but I can paste the exact same query from the screen
directly to MySQL and it works just fine. For example:
Here's the relevant PHP code:
==
$sql_insert_registration = sprintf(INSERT INTO
Registrations (
Class_ID,
prid,
Registrant,
Company,
Phone,
Email
)
VALUES (
$_POST[Class_ID],
$_POST[prid],
'%s',.
parseNull($_POST['Company']).,
'$_POST[Phone]',
'$_POST[Email]'
), mysql_real_escape_string($_POST['Registrant']));
echo pre.$_POST[Registrant]./pre;
echo pre.mysql_real_escape_string($_POST[Registrant])./pre;
echo pre.$sql_insert_registration./pre;
if (!mysql_query($sql_insert_registration, $con)) {
die('Error: ' . mysql_error());
==
Here's the output:
===
INSERT INTO
Registrations (
Class_ID,
prid,
Registrant,
Company,
Phone,
Email
)
VALUES (
355,
257,
'Brian O\'Brien',NULL,
'612-456-5678',
'paul_s_john...@mnb.uscourts.gov'
)
Error: You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near
'Brien', 'Class registration confirmation', ' This email ' at line 16
==
Also very oddly if the name O'Brien is input into the HTML form with two
apostrophes side by side (O''Brien) then MySQL will take it (but then of
course we have the problem of two apostrophes side by side inserted into
the MySQL table). For example:
===
INSERT INTO
Registrations (
Class_ID,
prid,
Registrant,
Company,
Phone,
Email
)
VALUES (
355,
257,
'Brian O\'\'Brien',NULL,
'612-456-5678',
'paul_s_john...@mnb.uscourts.gov'
)
You have been signed up for the class,
and a confirmation email has been sent to you.
=
Very strange.
I've checked various PHP variables and cannot figure out. It works fines
from another PHP server that's using the same MySQL database.
Thanks,
Paul
Probably needs a double backslash for O'Brien. One to escape the
apostrophe and one to escape the backslash escaping the apostrophe. ;-)
This would be because you're not using mysql_real_escape_string() on the
third parameter. Try this (not tested):
$sql_insert_registration = sprintf(INSERT INTO
Registrations (
Class_ID,
prid,
Registrant,
Company,
Phone,
Email
)
VALUES (%s, %s, '%s', '%s', '%s', '%s'),
$_POST[Class_ID],
$_POST[prid],
mysql_real_escape_string(parseNull($_POST['Company'])),
mysql_real_escape_string($_POST[Phone]),
mysql_real_escape_string($_POST[Email]),
mysql_real_escape_string($_POST['Registrant']));

Re: [PHP-DB] PDO + The Role of PHP + SQLite - Am I missing something?
. Use the SQLite3 extension; which is installed by default with PHP 5.3.0. As noted on the installation instructions for the extension: Note: This extension was briefly a PECL extension but that version is only recommended for experimental use. So avoid it like the plague and stick with the main extension ;-) Where do I get involved to help improve the situation? All the best, Lawrance. Any intelligent fool can make things bigger and more complex...

Re: [PHP-DB] PDOException: could not find driver (postgres)
What could be causing this please? Going direct, using pg_connect, is
not a problem.
Seems like a simple missing driver problem. Make sure you have the PDO
postgres driver enabled in your php.ini, it does not use the same driver
as the Postgres extension.
The code in question looks like
$pdo = new PDO('pgsql:host=localhost;port=5432;dbname=mydb', 'dbuser',
'dbpass');
(I think - I've yet to be able to debug it down to a single line)

Re: [PHP-DB] include_path in appache.conf
Try asking on the general list. This is not Db related at all, so your chances of getting answers here are pretty slim. This may be an apache question but I'd like to find the php answer first if one exists. I have several virtual hosts on a dedicated server. In a IFmodule mod_php5c container in an httpd.conf include file I have the following to create a unique include path for each virtual host: IfModule mod_php5.c php_value include_path .:/home/virtual/site#/path/to/include php_admin_flag safe_mode off /IfModule For one of the virtual hosts I've set up a dev site in a subdomain at dev.site#.com for development. In the root directory of this development site I have an .htacces file to create another unique include_path solely for this development subdomain. php_value include_path .:/home/virtual/site#/path/to/dev/includes Also in the httpd.conf I have Directory /home/virtual/site#/path/to/dev/root/ Allow from all AllowOverride All Order allow,deny /Directory The configuration is CentOS 5.3, Apache/2.2.3, PHP 5.1.6 I recently upgraded the OS from FC6 and the PHP version and I have not been able to get the include_path to change for this dev.subdomain. Even after restarting apache it PHPinfo tells me it is reading the server php.ini and the virtual host include path for the httpd.conf but it is ignoring the .htaccess file. I've even tried putting the php.ini with specific settings in the /home/virtual/site#/root directory to no avail. Any ideas how to make this work or even a better set up?

Re: [PHP-DB] Help for a beginner
Hi
Hi everyone, first thank you for ALL help and the understanding that I am new
to PHP and MySQL. This is a long email and for that I apologize but I am
trying to provide as much detail as possible. If this is the wrong list to
ask for help, kindly direct me to the proper authority.
I am trying to learn and I have built the following environment.
Windows Server 2008 Standard 32bit service Pack 2 with IIS7
mysql-essential-5.1.41-win32
php-5.3.1-nts-Win32-VC9-x86.msi
phpMyAdmin-3.2.4-english.zip
I followed the steps as detailed below (I already had IIS7 and CGI installed)
1. Install CGI PHP
http://www.trainsignaltraining.com/iis-7-install-fastcgi-php/2008-09-04/
2. Install MySQL
http://www.trainsignaltraining.com/install-mysql-on-iis7/2008-09-10/
3. Install PHPMyAdmin
http://www.trainsignaltraining.com/install-phpmyadmin-on-iis7-and-server-2008/2008-09-16/
This is a bit vague on details. In particular, when installing PHP did
you add the required extensions for MySQL, etc at step 6?
Create a test page containing nothing but this:
?php
phpinfo();
?
Open the page in your browser and verify that mysql, gd, and mbstring
are included. This will verify that:
1) you added them to your php.ini
and
2) This is the INI file actually being used by the server and not some
random other.
After I completed the installations
1. If I navigate to the PHP directory and type php -info it spews a ton of
data at me
AND
I created info.php which contains: ?php phpinfo(); ?
When I browse this, it correctly produces a page with all the info about
my PHP server. Although I do not understand much of it I believe this
confirms PHP is working correctly with IIS
2. I open the MySQL CLI and perform the commands outlined in Step 23 at this
page
http://www.bicubica.com/apache-php-mysql/index.php
This returns the expected results, confirming MySQL is working
3. PHP is configured to work with php_mysql.dll as per the steps in the
trainsignal links above so I begin!
I go to the phpmyadmin page, enter root and my password and after a long time
I get a FastCGI error. I am not ready to believe it because, in classic MS
form, it has several VERY different potential causes, and I have covered all
of those. Plus the error code is 0x which is like saying nothing... I
start thinking maybe it is not connecting to the mYSQL server right, the
instructions re: pma and the password made no sense to me so I fiddle with
that with no change.
I write the mysql_test.php page in step 5 of
http://www.bicubica.com/apache-php-mysql/index.php
This fails with: A connection attempt failed because the connected party
did not properly respond after a period of time, or established connection
failed because connected host has failed to respond.
Because the PHP failed I try with ASP...
%
set conn=Server.CreateObject(ADODB.Connection)
conn.ConnectionString=Driver={mySQL};Server=localhost;Database=test;User
Id=root;Password=youwish
conn.open
Response.write(Connected)
conn.close
%
This returns:
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Driver Manager] Data source name not found and no
default driver specified
/test.asp, line 4
I believe I have established MySQL is working, but for some reason it appears
that it cannot be reached This IS on the same server so firewall should not
be an issue, PLUS I confirmed the installer did create a hole. I turn off the
MS firewall to be safe, no change I try a repair of MySQL, I uninstall,
reboot and reinstall with no change.
NOTE: at several points I have tried iisreset and/or rebooting the system
with no change.
I start to research the matter and my mind is now unglued. I found something
referencing using mcrypt with PHPMyAdmin to speed it up and wondered if maybe
the long delay before the FastCGI error could be resolved so I tracked down
the dll, put it in my ext directory and changed my php.ini to reflect this --
file found at http://files.edin.dk/php/win32/mcrypt/
I found quite a bit about using libmysql.dll but there was no such file in my
install, I pulled down the .zip package and that also did not contain it, I
eventually found it in a 5.2.x archive but that does not seem to have helped.
I have tried enabling: only mysql, mysql AND mysqli, and only mysqli. None of
this seems to have done anything to change my situation.
Again, I apologize for the lengthy message, I hope I have accurately
described my issue in the right amount of detail.
Thank You!

Re: [PHP-DB] Does PHP5 support querying an MS Access MDE file?
2009/11/3 Timothy Legg php_l...@timothylegg.com:
2009/11/2 Timothy Legg php_l...@timothylegg.com:
Hello,
I have PHP Version 5.2.6-1+lenny3
I have been having difficulty using odbc_connect with an MS Access MDE
database. Â I do have php5-mysql and php5-odbc installed on this server.
Due to the rather poor search results regarding the topic of querying
MDE
files with PHP, I am becoming increasingly concerned that this file type
is not supported.
Is it possible to query an MDE file via PHP5 or should I try different
approach to querying the database from our linux server? Â I am
interested
in your thoughts.
Thanks for your help.
Tim Legg
If you have the MS Access ODBC driver installed, then have you tried
accessing the MDE as an MDB?
Yes, I have. The username and password are arbitrarily set since the
management hasn't provided that data for me yet. But I am not far enough
along to have run into a user rights issue. I get a warning and also an
error upon interpreting the page. I have checked the path to the database
file, and it is correct. I also checked file ownership and readability
permissions, too. So maybe the name of the driver is wrong; it does look
a little verbose to me, but it did come straight from the php.net online
documentation.
Error messages and source is below. Sorry, I modified the domain name in
the path for privacy.
Warning: odbc_connect() [function.odbc-connect]: SQL error:

You've got odbc, but probably not a driver for MS Access.
You need both.
I can't seem to find a unix driver for MSAccess.
Converting to a different DB would help (mysql, sqlite).
I had a similar problem. I had to access (pardon the pun) a very old MS
Access db. Being on x64 windows ODBC is not an option, so in the end I
used OpenOffice.org with a java driver to open it and copy data to MySQL.

Re: [PHP-DB] Very old question: Mysql and old authentication
Recently we update our Local Server to this: Apache Version : 2.2.11 PHP Version : 5.3.0 MySQL Version : 5.1.36 All works fine locally, but when we want to connect to a Remote Mysql Server 5.0.45 just can't, we got the mysqlnd cannot connect to MySQL 4.1+ using old authentication msg The solution as i see is to use the OLD_PASSWORD trick, but in this case we can't do that because the Server is a Shared server and yada yada yada.. change some in the Remote Mysql Server is not an option I think Php must provide a solution for this but we can't found it We use SqlYog 6.05 to connect to Mysql Server's. Why it works with NEW and OLD algorithm and Php don't ? Any help on this please ? The is an entry concerning this in 5.3.0 Backward Incompatible Changes http://php.net/manual/en/migration53.incompatible.php The new mysqlnd library necessitates the use of MySQL 4.1's newer 41-byte password format. Continued use of the old 16-byte passwords will cause mysql_connect() and similar functions to emit the error, mysqlnd cannot connect to MySQL 4.1+ using old authentication. The account you are trying to connect with is using an old password hash Your options are limited, either 1) Compile PHP to use the libmysql library instead of mysqlnd 2) Have the password updated to use the newer hash. Note The second option will prevent older clients connecting, including the mysql extension (but not mysqli) if it is not using the mysqlnd driver.

Re: [PHP-DB] losing MySQL resource
I'm maintaining a session. I successfully connect to a database ($DBConnect = mysql_connect()). I save the connection resource in a session variable ($_SESSION['connection'] = $DBConnect) ... to use in subsequent queries. It remains valid while the user is on the current page. print_r($_SESSION['connection']) yields 'Resource id #3', for instance. User browses to a new page ... in the same session. $_SESSION['$DBConnect'] no longer references a valid mysql resource. print_r($_SESSION['connection']) yields '0'. Other ordinary values saved in $_SESSION variables remain valid. Is there something special about a mysql resource? Not about the resource itself, no. PHP closes connections to a Db when a script ends, unless the connection is persistent, so while the resource IS saved, the connection to which it refers no longer exists. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- Niel Archer niel.archer (at) blueyonder.co.uk -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] newbie: how to return one iteration *per unique date (DAY!)* in a timestamp column?
You need to do this on the mysql side, not in php - php can't summarize the data before processing it, so you need to use something like the date() function in mysql on your timestamp column. http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html#function_date without knowing your original query it's hard to give an example, but: select distinct date(timestamp_column) from table; Thanks Chris, I am getting closer, but so far it is not iterating only once per unique 'date part of the datetime expression', it is returning all the rows in the table, including those with the very same date but different time in the value of the 'solarLandingDateTime' column. There is not alot of discussion in the mysql docs that I saw about how to work with DISTINCT. I need to grab data out of the 3 columns: solarLandingIP, solarLandingDir, solarLandingDateTime (this part of my SELECT is working). This is what I have: $foundTrackingRows=mysql_query(SELECT DISTINCT DATE(solarLandingDateTime) solarLandingIP, solarLandingDir, solarLandingDateTime FROM .$whichTable. ORDER BY solarLandingDateTime DESC LIMIT $Maxrecs2Show) or die(query failed: .mysql_error()); -Govinda There is no comma between DATE(solarLandingDateTime) and solarLandingIP which means the DATE column will use the alias 'solarLandingIP'.

ORDER BY solarLandingDateTime DESC LIMIT $Maxrecs2Show) or die(query failed: . mysql_error()); If you are aliasing a column it is better to use the optional AS keyword to avoid confusion.

Re: [PHP-DB] newbie: how to return one iteration *per unique date (DAY!)* in a timestamp column?
The distinct can only work as you want it to work when you only select the date column and only the date part (not the time part). Unfortunately I'm more an oracle DBA where the date functions are more clear to me so can not help with exact syntax. I think what you should be doing is returning the entire set of records (all required columns) in sorted by date order and loop through all of them. keep track of the last date processed and if it is the same as the current record, process nothing and go get the next record. BUT I am not quite sure what you are trying to achieve so my advise may be completely flawed. Jack 2009/8/3 Govinda govinda.webdnat...@gmail.com Doh, should have realised this before, but it's after 4 AM here. Jack is absolutely correct here, you are getting all the rows back because that is what the query asks for. Try this as your first step SELECT DISTINCT DATE(solarLandingDateTime) AS solarLandingDate FROM . $whichTable . ORDER BY solarLandingDateTime DESC LIMIT $Maxrecs2Show) or die(query failed: . mysql_error()); This should get your unique rows by date. The previous queries used ALL of the column names to form a unique row, and that made all the rows DISTINCT. Give us an idea of your table structure, if possible post the CREATE statement for it. Oops, forgot to mention that with the alias you can change the ORDER BY clause to use the aliased column data: ORDER BY solarLandingDate DESC this will only use the returned data instead of the entire column. If you are aliasing a column it is better to use the optional AS keyword to avoid confusion. MySQL's DATE function returns dates formatted as '-MM-DD' so DATE_FORMAT is not needed here. Niel, Bastien, thanks for your efforts to lead me to understanding this! I tried everything you both suggested. Ideally I would have some clear docs that outline the syntax for me, for such an example as I need.. and I would be able to check my code myself. Meanwhile, In every case, I just get every record in the table back as a result. So then I thought, try and make even a *simple* DISTINCT work, and then move on to the date thing... so I try this: //$foundTrackingRows=mysql_query(SELECT DISTINCT solarLandingDir, solarLandingIP, solarLandingDir, solarLandingDateTime FROM .$whichTable. ORDER BY solarLandingDateTime DESC LIMIT $Maxrecs2Show) or die(query failed: .mysql_error()); In all the records in this table, there are only 3 possible values in the 'solarLandingDir' column (TINYTEXT): diysolar solar_hm (null) but I still get all the records back, with each distinct 'solarLandingDir' column value represented several times. So something really basic is missing in my understanding/code. Can you see what it is? -Govinda -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- Jack van Zanen - This e-mail and any attachments may contain confidential material for the sole use of the intended recipient.

Re: [PHP-DB] Single Quotes in Form Inputs
I prefer PHP Data Objects http://in3.php.net/manual/en/book.pdo.php to addslashes and mysql_real_escape_string I prefer PDO myself. However, it is not necessarily safer. When using prepared statements the parameters are automatically escaped similar to mysql(i)_real_escape_string, if my reading of the documentation is correct. But as far as I can tell no escaping is performed on PDO::query or PDO::exec other than what you do yourself, so you have the same risks that need to be addressed. -- Niel Archer niel.archer (at) blueyonder.co.uk -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The main problem is you are not testing your results. With that code

mysqli_stmt_execute returns a boolean indicating success or failure.
You are trying to use it as a result set, which will not work. Replace:

Re: [PHP-DB] mysql_insert_id() and JOIN
Sorry my question... but why I must use JOIN if I can use SELECT * FROM table1 AND table2 AND table3 WHERE table1.id=table2.id=table3 not? thanks You can not use that syntax on MySQL (at least not on v5.0 or v5.1, I do not know about earlier versions). // Emiliano Boragina _ // Diseño Comunicación // -- Niel Archer niel.archer (at) blueyonder.co.uk -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] mysql_insert_id() and JOIN
Hi again I dont understand how to use this two I read php.net and other sites, but dont understand... http://dev.mysql.com/doc/ Available in the major languages, pick your filter and start reading. Having documentation in your own language may help a lot towards understanding. I have this four tables: table1, 2, 3 and 4 So the SELECT is like this?: ? $query_select = SELECT * FROM table1 FULL JOIN table2 FULL JOIN table3 FULL JOIN table4 ON table1.id=table2.id=table3.id=table4.id ORDER BY id ASC; mysql_query($query_select); ? This is with FULL JOIN... How identificate the left table if I want to use LEFT JOIN? The left table is the table to the left of the join. So: SELECT id FROM table1 LEFT JOIN table2... table1 is the left table and table2 is the right table (if you were to use a RIGHT JOIN). How is the UPDATE? And the INSERT I dont understand yet how is it? UPDATEs and INSERTs follow the same procedure. When you INSERT an entry into the main table, you then use the function mysql_insert_id() which will give you the value of the last 'id' column generated, which you can then use to insert data into the secondary tables. Im not to do a link between tables in PHPMyAdmin? Thank you very... VERY... much! If you are using MySQL 4.1 or later you should use the mysqli extension and not the older mysql one. UNLESS you are relying on the older style passwords, which is a BAD idea. -- Niel Archer -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] mysqli error
Whenever I run the following code, I get the error: Commands out of sync;

$x= count($inrec);
$arrFields = array();

$seqno++;
}
fclose($fpiDataAddr) or die(can not close file);
//disconnect
$sth1-close();
$sth2-close();
$mysqli-close();
?
However, if I close $sth1 (the select statement) before executing $sth2 (the
update statement), it works, but since I just closed $sth1, I have to
prepare it again. This is pretty inefficient considering the large data set
that I'm working with and the fact that I have to prepare and close my
select statement every single time I loop through. Is there any way that I
can run these statements error-free without having to close the select
statement ($sth1) every single time I want to execute my update statement
($sth2)?
You do not initialise your statement object. I would guess this is a
large part of the problem, although I'm not that familiar with prepared
statements in MySQLi.
See the documentation for mysqli::stmt_init[1] and the example for
mysqli_stmt::prepare[2] in the php documentation.

but I don't know where to look.
Would appreciate it greatly if anyone can help.

Check the file containing the first link again. '%5c%22' is the

Re: [PHP-DB] Bulk Insert from text file
Hi Could any 1 please help on how to insert using phpMyAdmin?? I haven't used phpMyAdmin in years, but here's how I'd do it in SQL with my favourite tool (SQLyog) LOAD DATA LOCAL INFILE 'C:\file_name.txt' INTO TABLE tbl_name FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n' IGNORE 1 LINES (col_name1, col_name2, col_name3); Some things to note. 1) the LOCAL keyword is for a file on YOUR computer. Remove it if the file is located on the server. Many shared hosting packages do not allow you to use LOCAL. 2) IGNORE 1 LINES assumes your file has column names or similar in the first line, and ignores them. Remove if the file does not have any, or increase the number if more than one non-data line at the start. 3) The two TERMINATED clauses define the line as being newline terminated and fields separated by tabs. Change these accordingly. You may need to add an extra backslash to escape the backslash for phpMyAdmin, I do not remember how that works with phpMyAdmin. -- Niel Archer -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You should be checking the mysql_query call for success and output the
error if it fails. Something like:
mysql_query($sql) or die('Insert failed: ' . mysql_error());
You'll now why it's failing then. Make sure you have error reporting
enabled.

Re: [PHP-DB] Inserting databasecontent within the same form
How can I overtake the fieldvalues of city and the first part of the phonenumber. It should read out the value of the zipfield and check them with the content of the table ort.

I'm having troubling understanding exactly what you want and I don't have time to decipher all the code in the hope it will tell me. My best guess is you want to use the zipcode from one table, to automatically add the city name into a form from another table. If that is so, you can do it with your query using a join. SELECT Kunden.*, City.name, City.vorwahl FROM Kunden LEFT JOIN City USING (zipcode) This assumes that `zipcode` exists in both tables and is unique in the City table. You should also process the City.name and City.vorwahl results for NULL results where `zipcode` does not exist in the City table. -- Niel Archer -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] showing warnings
This shows you have NO indexes on the table. Assuming that 'Tune_Name' contains unique entries for each row, I'd suggest you do the following as a minimum: ALTER TABLE Mobile_Tunes ADD PRIMARY KEY (Tune_Name); How's that going to help if he's getting all records from the table? Depends what you mean by help. Improve performance of the query, not at all, but that wasn't the original question. In a previous post he said he'd added indexes which his EXPLAIN output clearly shows is not the case. That is simply an example of how to add a PRIMARY KEY after creating the table. However, it will stop duplicate entries from being entered and prepare the way for when he's NOT selecting all rows, so is not entirely wasted. Also there's no way a database is going to use an index if there are only 4 rows in the table. True, but if it was only ever going to have 4 entries in it I doubt he'd be using a Db at all.

Hi Seeing as no-one else has replied to this, I'll make a comment. First off let me state I don't use PDO so I am not familiar with it. It would appear to me that your problem line is NOT the problem. It is only where the error is reported from. That line is a call to an object method, so the problem is in that method. As you haven't supplied the code for that method, no one is able to help. A point of note is that my $dbh is being created in my class constructor as a private. The method that is calling the prepare and execute statements is a public. I don't thing I'm trying to do anything new or exotic, I don't think I'm trying to convert the object to a string, just execute the query statement Probably not relevant, although it likely would be better to assign by reference. $prep_users = $this-dbh-prepare($sql_users); The main problem is we don't know what your $dbh is. We can guess it's a database handle, but that really doesn't tell us anything useful, like how it is constructed, and what the method you try calling is trying to do We need to see the code for the method: $prep_users-execute(); as that is where the error is occurring, and possibly the constructor and prepare methods also.

Re: [PHP-DB] problems with functions/included files/mysql resource
Hi,
In the function to connect to and select the database, I make the mysql-link
resource a global value.
It sounds like you've misunderstood 'global' variable. The global
statement needs to go inside the function where you want to use the
variable, not where you assign it. This tells that function to access
that variable from the global scope. You will need to have this
variable available at the global scope. Creating it inside another
function will not do, you must return that from the function to the
global scope too
e.g.
?php
$db = new mysql;
... some code ...
function UseDb()
{
global $db;
... some more code ...
}

Hi, see the docs for the date() function. 'I' returns 0 or 1 indicating Daylight Saving Time. However, it does this based on the settings for your installation. i.e. if your webserver is running on a host configured to U.S. time zone, it'll give U.S. DST results. Note that, any method will only remain accurate until the goal posts are moved next. The U.S. for example changed their DST dates last year (end date moved back). Australia and other countries have also recently changed. In these cases, either your code or the language need to be updated after such changes. .

Re: [PHP-DB] Inheritance question
Hi
For example (see below), lets say I would like to use public $one
property in a new class / method (such as class b)? What is the
best way to accomplish this? Any help and or suggestions are welcome.
class a {
public $one;
public function someMethod() {
$this-one = '1';
}
}
class b {
public $two
function someOtherMethod() {
$this-two = '2';
}
}
At least two ways you could go about it. Most straight forward would
be to inherit, like this:
class a {
public $one;
public function someMethod() {
$this-one = '1';
}
}
class b extends a{
public $two
function someOtherMethod() {
$this-two = '2';
}
}
$object = new b;
$object-someMethod();
$object-someOtherMethod();
print $object-one, $object-two;
In addition to that, if you actually need to use an instance of a
separately to b, you can pass the instance of a into b as a parameter.
Definition for 'b' would need to be something like:
class b {
public $a;
public $two
function __Constructor($dummy) {
$this.a = $dummy;
)
function someOtherMethod() {
$this-two = '2';
}
}
$object1 = new a;
$object2 = new b($object1);
$object1-someMethod();
$object2-someOtherMethod();
print $object2-a-one, $object2-two;
There are more than likely other ways to go about this. Check the
documentation for further examples of how to use classes in PHP.

sorry, I misunderstood your problem, it was not too clear to me as the
code you list shouldn't produce the output you supplied.
try this:
$array = explode(',', $csv);
print br= . $array[0] . \n;
print br= . $array[1] . \n;
for ($i = 2; $i count($array); ++$i) {
$txt.= br /= . $array[$i] . \n;
}
print $txt;

Re: [PHP-DB] csv problem.. read csv from var
hi
the problem i have is.. how about the csv is a var
DATA===
$csv=
A507257,3/2/2007,\Hematologi Lengkap,Cholesterol Total,LDL
Cholesterol,Trigliserida,HDL Cholesterol,Asam Urat,Gula Darah Puasa,Gula
Darah 2 Jam PP,Kreatinin,Ureum,Bilirubin Total,Alkali
Fosfatase,SGOT,SGPT,Urine Lengkap,Feses Rutin,Darah Samar Faeces,VDRL,Anti -
HBs,Total PSA,HBsAg,Anti - HCV Total\;
what should i do to make the ouput like above.
Use
$arry = explode(',', $csv);
to separate the variable into an array, then process it using foreach as
before

Re: [PHP-DB] Trying to add primary key to existing database.
Hi.
I don't know cPanel, but I expect it can run SQL directly, most panels
can. Use the ALTER TABLE ADD {INDEX|KEY} syntax to add indexes/primary
keys. You can use multiple columns, which together form a unique value
to create your primary key.

Re: [PHP-DB] What effects MySQL connection's character set
Hi all Finally identified the problem. Was pretty obvious in retrospect. The mysqli class (Improved MySQL extension OO style) defaults to latin1 as a character set, regardless of what PHP is using. Simple solution is to use the set_charset method (mysqli_set_charset for non OO) on the object, which will change the connection parameter.

Re: [PHP-DB] What effects MySQL connection's character set
Hi Thanks for this. That page didn't actually help, but one of the follow ups did. Apparently, despite being setup as UTF-8 throughout the Db, tables, and columns. The returned data still can default to Latin1. I've forced my test server to return UTF-8 (I hope) and am trying it out today. Fingers crossed! That turned out to be overly optimistic. Even Though the server is using UTF-8 throughout, it still defaults to latin1 on connections. So I used the SET NAMES utf8. It still will not work as I expect. I used the following code to test it. $Db = new mysqli($Host, $User, $Pass, $Db); $Db-query(SET NAMES utf8); $result = $Db-query(SHOW VARIABLES LIKE 'character\_set\_%'); $count = $result-num_rows; while ($count): $dummy = $result-fetch_assoc(); print $dummy['Variable_name'] . = . $dummy['Value'] . \n; --$count; endwhile; print \ncharacter_set_name: . $Db-character_set_name() . \n; Which results in the following output: character_set_client = utf8 character_set_connection = utf8 character_set_database = utf8 character_set_results = utf8 character_set_server = utf8 character_set_system = utf8 character_set_name: latin1 I can't find any documentation on PHP's character encoding, beyond the default_charset directive. Several of the functions/extensions have documentation, but not PHP itself. I suspect the problem is with php itself or the mysqli extension, which was my original thought and reason for my post. Anyone have any ideas? Niel -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] How to tell if a field type is auto_increment

Re: [PHP-DB] can u help me in PHP
Hi I read ur reply on newsreader abou mysqli and if i can use it in PHP4 My question is where can i find a link to download the mysqli extension separately without changing to PHP5 The MySQLi extension is available before PHP v5, but I couldn't tell exactly which version it was introduced with. I'm pretty certain it's part of 4.1. However, this doesn't mean it is enabled. If I recall correctly, on a windows platform it is available as a dll, but needs to be enabled in the php.ini. With other platforms, I think it needs to be compiled in with an additional switch. Niel -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi leaving me with the question: what does max_execution_time relate to? is it more like a maximum time without activity. max_execution_time is the time php gets to execute code.

Re: [PHP-DB] mysql rereading result set (fetch_assoc)
Hi Hi, I would ask which way is more efficient and save time? Save each row to array or mysql_data_seek(0) ? That totally depends on which resources are more valuable to you. The array will likely use more memory but be faster to process. While mysql_data_seek(0) would probably use no additional memory but be slower. It also might require you to duplicate code.

Re: [PHP-DB] search result error message
Hi,
there's no 'logic' error at all that I can see. It's more a design
error as it doesn't do the job the way that you describe it at all.
What actually happens is that the starting HTML (heading and table
start) is output before the database is even contacted, so there's no
way for you to take the table back if you don't receive any relevant
hits.
try something more like this:
?php
// database information
$host = 'xxx';
$user = 'xxx';
$password = 'xxx';
$dbName = 'xxx';
mysql_connect(localhost,$user,$password);
@mysql_select_db($dbName ) or die( Sorry But There Seems To Be A Problem
Connecting To The Database);
$query=SELECT * FROM shop;
$result=mysql_query($query);
$num=mysql_numrows($result);
mysql_close();
if ($num) {
?
h2Your favorites search result/h2divYou are here: index.htm Home
Your favorites/div
div class=internalContentArea sgtable

$shopname=mysql_result($result,$i,shopname);

$i++;

?/tbody/table index.htm Back to search div
/div
} else {
echo
div
div class='alert'The search criteria you entered did not generate any
result, index.htm please try again ./div
/div;
}
You'll probably need to polish this some, because I quickly cut/pasted
it before I go down the pub.

Re: [PHP-DB] Any hints lantin1 utf-8
Hi If you're storing non-latin character in a latin-1 table you are bound to get this problem. phpMyAdmin is simply showing you what you put there as far as it is concerned. You should switch to using an alternative encoding for the character set. UTF-8 would likely be best for you. Back up all the data before making the change, or it WILL be corrupted. If you primarily use non-latin character sets, I'd recommend making UTF-8 the default database character set Niel -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Any hints lantin1 utf-8
Hi I don't use phpMyAdmin myself and I can't remember if it supports UTF-8 encoding Whichever extension that your PHP is using is likely doing a conversion. this is something that the MySQL libraries handle. You can use this to extract the data from the tables and save it. As a test, dump a table's data into a file (have mysqldump, or phpMyAdmin create insert statements for the data). Create a table with UTF-8 encoding and attempt to process that file into it (copy/paste into phpMyAdmin if it's not to big) If that works, then you can go ahead and back up all your tables this way, and enter it into your new UTF-8 ones Without knowing more about your configuration (local/remote, versions, etc.) I can't suggest much else.

[PHP-DB] Moving phpNuke to phpBB
Hi I'm helping out someone move from PHPNuke to phpBB. Only the forums and users need to be moved. Nuke's Db structure for the forums seems to mimic phpBB's closely, which is no great surprise. Any advice or information would be greatly appreciated. For example, anyone know a way to convert the stored passwords? Nuke uses a 40 char hash, while phpBB only 32.

Re: [PHP-DB] Special Character
Hi Is it really a hyphen, or is it an en- or em-dash. The latter two could mess up in in some character sets. Niel -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Special Character
Hi David What you describe sounds like Word is auto replacing hyphens with either en- or em-dashes. This is a configurable option in Word that often defaults to on. Try using double quotes, If they get switched to 66's and 99's style quotes, then that is likely the problem. I no longer use MS Office for these and other reasons, so cannot tell you how to switch off this formatting. But it can be switched off, somewhere within it. The only other option I can think of would be to change your Db character set to one that can accept these extended characters. That might also mean changing some of Window's/Word's behaviour (to be using UTF-8 for example).

Re: [PHP-DB] Special Character
