Re: [PHP-DB] Number of Lines in Table.
Karl,
This works for small datasets, but when you have a large amount of data
(either in terms of storage or row count) it is no longer practical.
This is why people typically use the SQL row count instead of transferring
all of the data to php and doing the work there. It is much more efficient.
(You may wish to read about buffered vs unbuffered queries)

Hi Ethan,
Is it terribly important for you to get the count from MySQL?
Php does a nice job of this very easily.
$sql = SELECT itm FROM Purchases;
$result = mysqli_query($cxn, $sql);
if (!mysqli_query($cxn, $sql27))
printf(Errormessage: %s\n, mysqli_error($cxn));
if(!$result || (mysql_numrows($result) 1)){
return NULL;
}
/* Return result array */
$rowarray = mysqli_fetch_array($result);
$numrows = count($rowarray);
//return $rowarray;
print_r('Number of rows: '.$numrows);
print_r('Results { '.$row.' }');
Haven't tested this, but I believe it should work out the box. May need to
tweek to taste.
HTH,
Best,

If that fails and you aren't seeing any errors, I would try this prior to
the fopen() call:
if (is_writeable('/full/path/to/filename.txt'))
echo File is writeable. . PHP_EOL;
If is_writeable() returns false you need to look more closely at your
permissions.
If is_writeable() returns true and you still can't write to it, you would
then be in a very strange situation.
One other possible thing to try is to put the output of fprintf() into a
variable and echo that variable, just to make sure everything is working
fine there, but at a glance that all looks ok.

Do you check whether $fh2 is a resource after you fopen()?
btw, a better way than:
$ chown ethan:ethan filename.txt
Might be:
$ chown ethan:www-data filename.txt
$ chmod 664 filename.txt
This way you own the file, the server can write to it (assuming your server
has group www-data), and it is not world-writeable. (you almost never want
things to be world-writeable)

Re: [PHP-DB] www-data file
Another, safer, thing to consider would be setting a sticky bit on whatever directory the files will be in: http://computernetworkingnotes.com/managing-file-system-security/sticky-bit.html I've used sticky bits in a number of situations with multiple groups and users co-habiting environments quite nicely in the past.

Re: [PHP-DB] Calculating Past Dates In A Different Time Zone
Ron,
You could use the same technique here if you want to do the work in PHP:
=== php code ===
assert( convertToGMT('2013-11-01 00:00:00') == '2013-11-01 04:00:00' );
// EST offset by four hours
assert( convertToGMT('2013-11-07 23:59:59') == '2013-11-08 04:59:59' );
// EDT offset by five hours
function convertToGMT( $local_date ) {
$date = new DateTime( $local_date, new
DateTimeZone('America/New_York') );
$date-setTimezone( new DateTimeZone('GMT') );
$gmt_date = $date-format('Y-m-d H:i:s');
return $gmt_date;
}
=== php code ===
For date intervals:
=== php code ===
$date = new DateTime( '2013-11-01 00:00:00', new
DateTimeZone('America/New_York') );
$date-add( new DateInterval('P7D') ); // 7 days
$date-setTimezone( new DateTimeZone('GMT') );
assert( $date-format('Y-m-d H:i:s') == '2013-11-08 05:00:00' );
=== php code ===
Just be careful with mutable vs. immutable DateTime objects ;)
I wouldn't mess with 23:59:59. Instead, use specific comparisons to
make it work:
SELECT * FROM `journal_entry` WHERE `occurrence_date` = 2013-01-01
00:00:00 AND `occurrence_date` 2013-11-08 00:00:00;
...if you're really that concerned about that one second. Alternatively
you could use DateTime::sub() to subtract a single second and still use
BETWEEN.
I would argue that one second doesn't matter for almost any application,
but I obsess over such details myself, so I can't argue that point too
strongly ;)
For reports on a given month or range of months, you can use different
DateInterval values (P1M, etc.), or get the number of days in any
given month from PHP's date() command.
btw, if you were considering doing all of the work in SQL (MySQL), you
could do:
=== sql query ===
SELECT * FROM `journal_entry` WHERE `occurrence_date` BETWEEN
CONVERT_TZ( DATE_SUB(:end_date_in_local_time, INTERVAL 7 DAY),
:local_tz, GMT )
AND
CONVERT_TZ(:end_date_in_local_time, :local_tz, GMT);
=== sql query ===
For the specific problems you called out:
1) Calculating what time it is in GMT when it is midnight in the user's
time zone X days ago:
You just need to use DateTime::sub() to subtract X days
(DateInterval('P'.$X_days.'D')) from midnight today (date('Y-m-d
00:00:00')), then convert the result to GMT. Note that this is midnight
this morning from PHP's perspective if you use date()... my example
below takes into account the user's timezone.
2) Calculating midnight on November 1st 2013 in the user's time zone:
$date = new DateTime( '2013-11-01 00:00:00', new
DateTimeZone($user_tz_str) );
I'll finish with one very specific example for one of the problems you
mentioned.
3) Building a query for the last 3 months.
=== php code ===
$user_tz_str = 'America/New_York';
$tz_user = new DateTimeZone($user_tz_str);
$tz_gmt = new DateTimezone('GMT'); // or UTC, or whatever...
// I wasn't sure which way you meant here, so I did a few.
// I think you'll be able to figure out what you want to do based on one
of these or some variation on them.
$starting_point = 'this morning'; // 'this morning' or 'now' or 'ending
before this month'
if( $starting_point == 'this morning' )
{
// do 3 months back from midnight this morning.
$day_date = new DateTime();
$day_date-setTimezone( $tz_user );
// $day_date-format('Y-m-d').'00:00:00' is midnight this morning
from the perspective of the user's current time
$end_date = new DateTime( $day_date-format('Y-m-d').'00:00:00',
$tz_user );
}
else if( $starting_point == 'ending before this month' )
{
// do three months prior to when this month started.
$day_date = new DateTime();
$day_date-setTimezone( $tz_user );
$end_date = new DateTime( $day_date-format('Y-m').'-01 00:00:00',
$tz_user );
}
else
{
// use now. User timezone doesn't even matter.
$end_date = new DateTime();
}
$start_date = clone $end_date; // clone the object or you'll make a mess
of things.
$start_date-sub( new DateInterval('P3M') ); // subtract 3 months. You
could use whatever DateInterval you want here.
// make sure you do timezone conversion AFTER the DateInterval is
subtracted, if you care about daylight savings time.
$start_date-setTimezone( $tz_gmt );
$end_date-setTimezone( $tz_gmt );
/*
* At this point:
* $start_dt-format('Y-m-d H:i:s') == the beginning of our interval in GMT
* $end_dt-format('Y-m-d H:i:s') == the end of our interval in GMT
*/
// We'll use a PDO prepared statement as an example here. Assume $dbh
comes from somewhere above...
$sth = $dbh-prepare( 'SELECT * FROM `journal_entry` WHERE
`occurrence_date` BETWEEN :start_dt_gmt AND :end_dt_gmt' );
$sth-bindParam(':start_dt_gmt', $start_dt-format('Y-m-d H:i:s'),

Re: [PHP-DB] chmod
Emiliano, This question is totally out of scope for this mailing list. It has nothing to do with databases at all. Also, you should _almost never_ use 0777 for permissions. You probably want 0644. (Owner can read/write, all others can read.) Regarding your question in general, it sounds like you are running this on a Windows environment. I can't personally speak to whether chmod() works well in that environment or not (I would never run a windows server or dev environment for that matter), but I suspect it may not be working as expected based on what you are describing, especially if you are using an older version of PHP. I would be willing to further help you diagnose the problem (others may be as well), but I really think this does not belong on this mailing list and, as such, those discussions should be held off-list.

ok - new to using pdo functions, but I thought I had a handle

I'm writing out to my page an input tag with the following

I can confirm it by using my browser's view source to see
that is
exactly how it exists in the page.
When I hit a submit button and my script retrieves the 'post'

debugging steps are showing that the var $_POST['team']
contains the
above value with a backslash (\) already inserted. This is
causing me
a problem when I then try to use pdo-quote to safely encode it

updating my sql database.
My question is - why does the POST var show the \ char before I
execute the 'quote' function?
You're right! But I must not understand something.
My root folder has a php.ini file with the magic quotes set off.
Doesn't
that carry on down to folders beneath it?
I would check phpinfo() to see if it is being overridden.
-Matt
Create an info.php file containing ...
?php
phpinfo();
Save that in the directory containing PHP and one other directory.
Load them via your browser. See the settings for the magic_ and
see where the php.ini configuration file is being loaded.
It may be that your ini file is completely ignored!
Matt Rich,
I have a small php.ini in my domain's 'php' folder as well as in my
webroot folder. I was under the impression that the overrides would
be applied to all folders below my webroot, but apparently it is not
happening.
How do 'pros' replicate their .ini settings thru all of the
application folder? Not thru settings within the scripts I hope - I
thought I read that the was not a very efficient way to do it and
that a php.ini file was the best since it would be merged with the
master one installed by my hoster.
Jim,
Personally I rarely have the need to override the php.ini settings
for a particular host on a server. (Granted I never work in shared
servers)
Assuming you are using Apache and the standard module configuration,
you can use .htaccess files to override many settings from php.ini
Official reference pages:
http://php.net/manual/en/configuration.changes.php (you might want
to read through the comments here, too)
http://httpd.apache.org/docs/current/howto/htaccess.html
Example and some discussion here as well:
http://davidwalsh.name/php-values-htaccess
If you are using another web server or running PHP as FastCGI you may
need to consider other options (changing the setting globally or
doing a require_once() of your config changes?, or see the FastCGI
example here:
http://www.askapache.com/php/php-htaccess-tips-tricks.html)

You could just check for it with php and add or strip accordingly.
adding slashes if magic_quotes is disabled:
if (!get_magic_quotes_gpc()) {
$var = addslashes($var);
}
stripping slashes if magic_quotes is enabled and your planning on
sanitizing yourself.
if (get_magic_quotes_gpc()) {
$var = stripslashes($var);
//do your own sanitizing
}
I wouldn't suggest the last one if your not going to sanitize yourself
as it will make you vulnerable.
But all-in-all very simple to implement.

You shouldn't be sanitizing using addslashes() regardless, or using
magic_quotes_gpc at all really, if you can help it.

I've been working fine with a php.ini that merges onto the full ini file. Suddenly this new appl is not seeing the overrides. Any info you can point me to about how php.ini files work? The manual doesn't get very specific about it. You would only have to modify multiple .htaccess files if you have multiple document roots that need this change applied to them. Otherwise just create/edit the .htaccess file in the document root for the site you want the change applied to. .htacess isn't always read by Apache. Some configurations tell it to read or not read that file, so you may need to check that as well. phpinfo() will tell you which php.ini file is being used-- if you edit the one it says is being used you should see a change unless something else is overriding the setting (like an .htaccess file or your code). -Matt -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] Programs not running
Ethan, I'm not sure this conversation is appropriate for this mailing list. This question has probably been answered 1000 times on the general php list. In my experience, the problem you are experiencing is caused by one of two issues: 1) A major parsing problem (sometimes no error is displayed-- you just get no output.) 2) An out-of-memory error (which can sometimes cause scripts to bail out even when error reporting is enabled) I would recommend: - Setting the error reporting level in php.ini rather than with error_reporting() while you debug this issue - Systematically comment out your entire script (in which case you should be able to run it and do something simple like display a string), then slowly add things in until you no longer receive output. ex: ?php error_reporting(-1); echo this is my page!; this_will_still_die(;) ? becomes: ?php echo test; /* error_reporting(-1); echo this is my page!; this_will_still_die(;) */ ? then: ?php echo test; error_reporting(-1); /* echo this is my page!; this_will_still_die(;) */ ? Call me crazy, but I swear I've encountered problems where even comments weren't enough- I've had to actually remove the code from the file and paste it in bit by bit. PHP can be extremely annoying sometimes. -Matt On 01/03/2013 08:54 PM, Ethan Rosenberg, PhD wrote: = Jim and Matt - Did all the suggested debugging prior to sending the eml.

Re: [PHP-DB] CSV storage InnoDB?
Karl, Typically I would do this as multiple rows rather than comma-separated data in one field. If you go this route, you may consider adding an unsigned int primary key (with auto increment) on the discounts table so you consume less storage space and can do joins more quickly. `discounts`: id discount_code product_id_or_whatever 1sfeijfkjx 34 2kbgrlijf 36 `user_discounts`: user_id discount_id 1231 1232 4563 If you really needed to SELECT the data with comma separation, you could use something like GROUP_CONCAT (http://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html#function_group-concat), but I would try to avoid that. This is a very basic design principle for relational databases. You may want to do some more reading about database architecture in general. That said, you could use a TEXT field to store a comma separated list, I just wouldn't recommend doing it that way. -Matt On 11/26/2012 06:01 PM, Karl DeSaulniers wrote: On Nov 26, 2012, at 7:29 PM, Bastien wrote: Bastien Koert On 2012-11-26, at 7:43 PM, Karl DeSaulniers k...@designdrumm.com wrote: Hello all, Quick question.

Sorry, I should have elaborated. There is a table that holds all the discount codes. Keeps them grouped with a product id or if they are to be applied cart wide.

In these tables is where I need to insert this field. An example of the discount table would be like: Discount table: | discount code | product id | discount perc. | discount type | +-+-+--+---+ |8lKzv_=== | 22 | 20 | item | +-+-+--+---+ | NpLK23 | 0 | 50 | cart | +-+-+--+---+ but in the user table for instance: User table: | user_discounts | +---+ |8lKzv_===, YjMlio_===, NpLK23, hDflp0_=| +---+ Just trying to figure out the best way to store multiple variables if you will in one field like so. Or if this is even the best way to do such a thing. I am open to alternatives. I will need to read this new filed out of the database as an array that I can then utilize with an in_array or something of the sort.

Re: [PHP-DB] CSV storage InnoDB?
BLOB and TEXT are basically the same thing, except that BLOB can be used
for storing binary data (like an image).
You would only need one additional table to do what I was describing,
but if you're dead-set on using a comma separated list then TEXT or
LONGTEXT is probably what you want, depending on how large you
anticipate those lists becoming.
If you care about efficiency you may want to look at this blog post:

Hi guys,
Thanks for your responses.
I do have a auto incremented id for the codes. Yes multiple product
can have the same code. Table is as follows.
CREATE TABLE `discounts` (
`d_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`p_id` int(10) unsigned NOT NULL DEFAULT '0',
`d_discode` varchar(16) CHARACTER SET utf8 NOT NULL DEFAULT '',
`d_type` enum('item','cart') NOT NULL DEFAULT 'item',
`d_discamt` float(5,2) unsigned NOT NULL DEFAULT '0.00',
`d_discper` int(3) unsigned NOT NULL DEFAULT '0',
`d_qty` int(10) unsigned NOT NULL DEFAULT '0',
`d_description` varchar(25) CHARACTER SET utf8 NOT NULL DEFAULT '',
`d_expire` datetime NOT NULL DEFAULT '-00-00 00:00:00',
`d_user` varchar(30) CHARACTER SET utf8 NOT NULL DEFAULT '',

PRIMARY KEY (`d_id`),
KEY `d_discode` (`d_discode`),
KEY `d_expire` (`d_expire`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 ;
This is where the discounts and their codes and any info are stored
including who set the discount (this user does not apply to our
situation, FYI).
Then in say the user table I set the codes that user gets to use.
...
`u_discodes` (???This is my question. What to use???) CHARACTER SET
utf8 NOT NULL DEFAULT '',
...
I just need to store the separate codes a user has available to them
here. So what would be the best suited?
I am thinking a blob or text, because like tamouse said, I can explode
the results and or check an in_array on the results.
It seems the logical route to me for what I am doing. u_discodes just
is a reference to check against.
I then apply the amounts or percentages according to what is in the
discounts table for that code.
Am I moling this? Missing something?
I'd like ( I guess ) to stay away from creating separate tables that
hold the references for users, products, carts, etc and their codes.
To me the blob seems so much simpler.
But alas, I may have answered my own question.

Re: [PHP-DB] Re: Formatting
FYI, this really is not the appropriate mailing list for these types of
questions.
Are you positive they are empty lines? i.e., are they in the html code
of the page, or only appear as empty space in the rendered page?
If they are just in the rendered page, in addition to losing the
/div in the middle of your table (as someone has suggested), you
might also want to check your stylesheets. In particular, this looks
like it could cause some strange things to happen depending on what
you're doing with it:
td class=first-col
Try loading up firebug and looking at the table element and the elements
around it to see if there is some strange padding. Or, try disabling any
stylesheets you are loading with the page to see if it still renders in
an undesirable way.
Good luck,

I would recommend you consider Jim Giner's remarks as well. PHP's error
message was giving you exactly what you needed to solve the problem with
the code I gave you. There is even a note about using
call_user_func_array() in the documentation about
mysqli_stmt_bind_param(). In fact, the first example in the comments on
the mysql_stmt_bind_param() page shows one way of solving the issue you
are having. (http://php.net/manual/en/mysqli-stmt.bind-param.php)
I think you will find people a lot more willing to help if you can show
that you've done basic research like looking at the documentation for
the function you are trying to use :-)
If you don't understand references, I would recommend reading about
them: http://php.net/manual/en/language.references.php

Dear list -
SEE CORRECTION IN $_POST VARIABLE BELOW.
Thanks to all for your help.
I hope [??] that this question will solve all the remaining problems.
So that we are on the same page, here is what was previously stated.
mysqli_stmt_bind_param expects three variables, in this order
mysqli_stmt_bind_param($stmt, num, $a, $b, $c)
Where stmt is the query w/ the ?? that is
SELECT Site, MedRec, Fname, Lname, Phone, Height, Sex, Hx, Bday, Age
FROM Intake3 where 1 AND (Site = ?) AND (MedRec = ?) AND (Sex = ?)
and num is the number and type of variables is the query, in this
case 'sis'
$a $b and $c are the variables to be inserted, in this case:
$a = $_POST['Site'];
$b = $_POST['MedRec'];
$c = $_POST['Sex'];
As I seem to have found, the variables cannot be a string or
components of an imploded array.
This is a search function that will take patient supplied data and
search the Intake database to determine the Medical Record Number.
There are nine variables in the database, and I never know which
variables the patient will give.
Based on the database, it is easy to set up the correspondence. The
database is searched in the order of the correspondence and the
letters can be
immediately determined...
$a = $_POST['Site']
$b = $_POST['MedRec']
$c = $_POST['Fname']
$d = $_POST['Lname']
$e = $_POST['Phone']
$f = $_POST[Height']
$g = $_POST['Sex']
$h = $_POST['Hx']
$i = $_POST['Bday']
$i = $_POST['Age'] - Corrected
The challenge is to be able to dynamically select the variables that
will go intomysqli_stmt_bind_param.
Advice and help, please

Re: [PHP-DB] Prepared Statements - Select
Ethan,
I believe the root of your problem is that you are passing $bind3 as a
string to mysqli_stmt_bind_param() where the function was expecting
multiple arguments.
Let's say $binder = array( 'one', 'two', 'three' ); // I'll call this
$arguments in my example below
and $typer = array( 's', 'i', 's' );
Right now you are effectively doing this:
// doesn't work
mysqli_stmt_bind_param( $stmt, 'sis', one, two, three );
Consider using the call_user_func_array() method:
// Pass elements in $arguments array to the
mysqli_stmt_bind_param() method as separate arguments.
call_user_func_array( 'mysqli_stmt_bind_param',
array_unshift($arguments, $stmt, $types) );
In this case, this call_user_func_array() call would effectively be the
same as:
mysqli_stmt_bind_param( $stmt, sis, 'one', 'two', 'three' ); //
assuming you imploded $typer into $types
Also note that your $binder array seems to have commas as elements. It
would need to have just the actual parameters (so, count($arguments)
would be 3).
It looks like you've been making good progress with your script.
It's a little tough to tell everything that you're doing here, but take
a look at this and see if something like this helps simplify things at all:
/ Begin untested code snippet /
$sql1 = 'SELECT whatever FROM table WHERE 1 ;
$allowed_fields = array(
'Site' = 's', // fieldname is key, bind type is value
'MedRec' = 'i',
...
);
$types = '';
$args = array();
foreach( $allowed_fields as $k = $type )
{
if( !array_key_exists( $k, $_POST ) )
continue;
$args[] = $_POST[$k];
$types .= $type;
$sql1 .= AND ($key = ?) ;
}
$stmt = mysqli_prepare( $mysql_resource, $sql1 );
if( !call_user_func_array( 'mysqli_stmt_bind_param',
array_unshift($args, $stmt, $types) ) )
throw new Exception( 'Error while binding parameters' );
/ End untested code snippet /
As indicated, I didn't test that script. It's just to illustrate an idea.
Hope this helps,
Matt

Here is another one
I wish to accomplish the following
mysqli_stmt_bind_param($stmt, 'sis', $_POST['Site'], $_POST['MedRec'],
$_POST['Sex']);
This statemnt was hand coded. I wish to be able to generalize it.
Therefore -
$sql11 = SELECT Site, MedRec, Fname, Lname, Phone, Height,
Sex, Hx, Bday, Age FROM Intake3 where 1 ;
$allowed_fields = array
( 'Site' =$_POST['Site'], 'MedRec' = $_POST['MedRec'],

'Phone' = $_POST['Phone'] , 'Height' =
$_POST['Height'], 'Sex' = $_POST['Sex'], 'Hx' = $_POST['Hx'],
'Bday' = $_POST['Bday'], 'Age' = $_POST['Age'] );
$z0='$_POST';
$z0 .=['Site'];
$z1='$_POST';
$z1 .=['MedRec'];
$z2='$_POST';
$z2 .=['Fname'];
.
.
.
$indeces = array(
0 = array
(
'tpe'= 's',
val = $z0
),
1 = array
(
tpe = i,
val= $z1
),
.
.
$binder = array(); //array to hold variables
$typer = array(); //array to hold variable type
$position = -1;
foreach ( $allowed_fields as $key = $val )
{
$position = $position + 1;
if ($val != '')
{
array_push($binder, $indeces[$position]['val']);
array_push($binder, , );
array_push($typer, $indeces[$position]['tpe']);
$sql11 .= AND ($key = ?) ;
}
}
array_pop($binder);
The above generates the following query:
SELECT Site, MedRec, Fname, Lname, Phone, Height, Sex, Hx, Bday, Age
FROM Intake3 where 1 AND (Site = ?) AND (MedRec = ?) AND (Sex = ?)
//Construct the strings for the mysqli_stmt_bind_param statement
$typ2 = implode($typer);
$typ3 = ';
$typ3 .=$typ2;
$typ3 .= ';
$bind3 = implode($binder);
//This statement works perfectly. mysqli_stmt_bind_param($stmt,
'sis', $_POST['Site'], $_POST['MedRec'], $_POST['Sex']);
//This one fails
mysqli_stmt_bind_param($stmt, $typ3, $bind3);
With the following error message:
Warning: mysqli_stmt_bind_param(): Number of elements in type

echo br /$typ3;'sis'

Re: [PHP-DB] Re: Many columns (as FK) vs 3x more Columns (in the same table)
Bruno, This schema layout seems a little odd to me. Maybe I'm just misunderstanding the use. Correct me if I'm wrong here: Each row in the bill table is a customer? (or some other lookup value for which you're generating the data grid?) I assume the 15 fields from your original message are the 20 fields you are describing here? The values inside the Bill table are 100% unique and point to the Value table? You're trying to generate output that looks like this? CategoryRegisteredBilledTotal electricity_use 120,00 150,12102,36 electricity_demand130,00 150,12102,36 ... for a particular row in the Bill table where ID=something ? If this is true, I would consider normalizing this a bit more. If you break the columns in your bill table out into their own table, expand your values table a bit, you could end up with something like this: categories table: idcategory_name 1 electricity_use 2 electricity_demand ...... (where id is the primary key) bill_data table: ID_from_original_bill_tablecategory_idregistered billedtotal 1 1 120,00 150,12102,36 1 2 120,00 150,12102,36 ... (where (ID_from_original_bill_table, category_id) is the primary key) And do queries like this: SELECT c.category_name, bd.registered, bd.billed, bd.total FROM categories AS c JOIN bill_data AS bd ON c.id=bd.category_id WHERE bill_data.ID_from_original_bill_table=whatever; Or am I still not understanding correctly what you're trying to do?

So - your table has 15 records in it, each with 3 columns. Add a key field to give each row an identity and that's it. No?

Re: [PHP-DB] Re: Problems w/ insert
Ethan, I am curious why you are using mysqli_stmt_bind_result() on a statement that is an INSERT query? I don't use mysqli, but as I read the documentation it seems to me that this method is intended to bind results from a SELECT query into variables so that you can simply call mysqli_stmt_fetch() in a loop and have the variables magically contain the data from the next row. Perhaps mysqli is confused because you are both mapping data to be bound (with mysqli_stmt_bind_param()) and to be returned (with mysqli_stmt_bind_result()) on the same INSERT query? If you are just trying to insert, you should only need mysqli_stmt_bind_param() (which, by my count, has one parameter too many right now in your code) and mysqli_stmt_execute() (and probably not mysql_stmt_bind_param() and mysql_stmt_fetch()).

Re: [PHP-DB] PDO user question
Brandon: RAM is cheap, but not always expendable depending on what you're doing. Using count() on results from PDOStatement::fetchAll() is fine on small result sets. Keep in mind that this will certainly blow up on very large result sets, especially depending on your memory_limit for php. Avoiding this problem is the primary reason I use prepared statements for retrieving data. If you're working with small result sets you could avoid using prepared statements altogether, which would greatly simplify doing something like getting a row count. If you don't absolutely need your code to be portable across multiple database servers, I would encourage you to experiment with the rowCount() method and see if it works for your setup. (I ran a quick test in my mysql environment and it worked fine for a SELECT statement. Sqlite doesn't seem to support it because the actual sqlite library doesn't support it. Haven't looked into postgres or others.) Another thing to be aware of (at least with mysql), and speaking to Lester's point, is that you can use SQL_CALC_FOUND_ROWS (with mysql, anyway) to get a total count when you are using LIMITs on your result set (which would be advisable if you're returning these results in a web interface). -Matt On 09/09/2012 02:40 PM, brandon wrote: That's how I'd do it.

Re: [PHP-DB] Wow, this is weird
You are probably having problems with Array[name] because of the way
you are inserting variables into the query.
You're doing this:
this is my string with '$_POST[image][name]'.
Instead, try this:
This is my string with '{$_POST['image']['name']}' in it.
or this:
This is my string with ' . $_POST['image']['name'] , ' in it, using
the concatenate operator.

I just your tried suggestion and now it does insert something into the

So I believe my first mistake was, I should have realized the line
$_FILES['image']['name'] is an array, so of course the image name isn't going
to be there until I extract it from the array. Correct?
Also, if you're not just doing a simple test script, you should probably
use mysql_real_escape_string() on your parameters in the query.
I started with a simple form and I'm working my way up the ladder, from
posting stuff, sticking stuff in a db using stuff like getimagesize(), and then
next I'm going to work some more with sanitization of forms and inserted data
in the db. :-)
By the time I'm done with this, I'm hoping to have a much greater
understanding of FILTER_SANITIZE_STRING, getimagesize, and whatever else I
would need to know about forms and inserting into db's. :-)

I think PDO::ERRMODE_WARNING tells PDO to give PHP warnings versus throw exceptions when there are problems (if I'm understanding it properly). -Matt -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
