Re: [PHP] PHP MYSQL sorting
You can use javascript to trigger an onclick function every time a checkbox is selected. The onclick function can make an ajax call to a remote php script which can then make the database query.

This now will return all results in an html format from all queries.
Now I could “tee” this to a file and save the results returned if I so choose
to save the result of the display .
Let’s say I want to be lazy and write a php MySQL query to do the same so
that any result I queried for would return the html results in a table
without actually writing the table tags in the results.
Is there a mysql_connect or select_db or mysql_query tag option to do that
since mysql can display it from the shell?
Here is my rendition of an result to HTML table output function.
This is normally used within my db class
but I have modified it to work with a MySQLi result object
function debug($result) {
/* get column metadata */
$html = 'table border=1tr';
foreach ( $result-fetch_fields() AS $val ) {
$html .= 'th'.$val-name.'/th';
}
$html .= '/tr';

foreach ( $row AS $value ) {
$html .= 'tdnbsp;'.$value.'/td';
}

I played around with your code tonight and got this working on a test
server:
?PHP
$db_billing = mysql_connect($DBHOST, $DBUSER, $DBPASS) or die(Could
not connect: .mysql_error());
$db_selected = mysql_select_db($DB, $db_billing);
if(!$db_selected) {
die(Can't use database: . mysql_error());
}
if (!$db_billing) { die('Could not connect: ' . mysql_error()); }
$sql = SHOW TABLES;
$result = mysql_query($sql) or die(query failed:
.mysql_error());
$resulttest = mysql_fetch_assoc($result);
foreach($resulttest as $k = $v) { //line 62
$ssql = DESCRIBE .mysql_real_escape_string($v);
$rresult = mysql_query($ssql);
echo b.$k./b:br /\n;
echo pre\n;
print_r(mysql_fetch_assoc($rresult));
echo /pre\n;
echo br /\n;
}
?
The only big difference from what you had is that I moved the
mysql_fetch_assoc($result); into a separate line rather then running
it from the foreach...
Let me know if that helps.

What you just offered just shows info about only the first column in
the table.
I got this working to show info about all the columns in the table:
$ssql = DESCRIBE billing_table;
$rresult = mysql_query($ssql);
echo hr /pre\n;
while ($row = mysql_fetch_assoc($rresult)) {

(the advantage is that there is no common key for all records, just gonna make a hackers life tougher) Personally, I would prefer to situate all encrypted records in their own table with a structure like: record_id int auto number main_record_id (whatever your system has as a main record) field_namevarchar(32) enc_value varchar(255) you could also add some tracking [last_access_time] int (unix timestamp) [last_access_id] varchar(32) if you want to store the data with the record -- Bastien Cat, the other other white meat

Re: [PHP] PHP-MYSQL Question
This isn't PHP but mysql question.
You didn't mention that the table itslef is created or not. If not, then it
is probably a mysql error,
maybe your installation of mysql doesn't support INNODB.

('one'),('two'),('three'),('four'),('five'),('six'),('seven'),('eight'),('nine'),('ten');

The physical order of the rows changed (as you can see) but it does not
re-use the id's that were deleted.
Ordering by the id will get you the last bunch inserted.
If you're using innodb you'll have to be aware it's transaction
specific, if you're using myisam it will be system wide.

Assuming you want to use straight PHP (as opposed to an
object-relational mapping framework), you have several choices. You can
use the native PHP mysql functions to access the tables. Or you can use
PHP's PDO classes (or similar). Both are documented at php.net (and very
well, I might add).
Your ER diagram is a visual representation of various CREATE TABLE
statements in SQL. Using straight PHP, you'll need to learn to use the
SQL language to make queries and changes to the tables. It is relatively
simple to learn, but essential unless you want to use some odd
framework, as I mentioned before. SQL queries would look something like
this:
$result = mysql_query(SELECT name, address FROM people WHERE country =
'Germany', $connection_info);
Then, you would do something like:
$person = mysql_fetch_array($result)
And $person would look like this:
$person = array('name' = 'Helmut Schmidt', 'address' = '123 Anystrasse');
I want to stress that PHP is *not* a *visual* language. You have to sit
down with an editor and write it. Very unlike programs which allow you
to design tables using visual means.
Hope that helps.

I think it might involve a mySQL alias-technique but I could be wrong. Right now, my PHP call to generate the search is this: $query = 'SELECT * FROM wine WHERE MATCH(producer, varietal, appellation, designation, region, vineyard, subregion, country, vintage) AGAINST ( ' . $searchstring . ') ORDER BY producer LIMIT 0,100'; Maybe there's a good way to do it with the table as is... but I'm doubtful. I would create a second field that contains a pre-processed version of the name that performs stripping to achieve what you want. This could be done by a PHP script when the data is inserted into the database, or if not possible like that, then a cron job could run once in a while, check for entries with this field empty and generate it.

As of this point, it's all or nothing b/c we are dealing with fairly crucial information. However, I will look into building savepoints into the class so that I'll have that option in the future. Sounds like a difference in semantics :P In my head they're the same thing - if the middle bit fails, it'll roll back. If it works, you continue doing whatever you're doing. If everything succeeds then you commit everything at once. If part of something fails, then you roll it all back. At least you're more protected in the situation I mentioned above where you'd get partial data saved. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Currently, my thoughts for doing this are:

$this-db-query(SELECT...); // Run my queries here

// Do some PHP logic here
$this-db-query(SELECT...); // Run more queries
$this-db-query(INSERT...);
$this-db-commit(); // Commit transaction
}
?
If there was a failure in one of the queries, that would be caught in
the database class ('db' instance) and ?php $this-rollback(); ?
would
be called. Note that all the tables are InnoDB and the above
code/functionality works.
Ideally, I would have liked to use stored procedures, but that
decision
was not mine. So are there any complications I'm potentially missing?
I'd get your db class to handle nested transactions, so if you had
something like this:
$db-begin();
someFunctionThatNeedsTransactions();
...
.. oops, need to rollback.
$db-rollback();
the bits between someFunction and the rollback will be committed
(by
the function) and can't be rolled back.
See http://dev.mysql.com/doc/refman/5.0/en/savepoints.html
The situation might not come up but it can't hurt to have it already
built in just in case.
This doesn't appear deal with *nested transactions.* It appears that
it will use a single transaction and you can just save up to a certain
point upon failure. As of this point, it's all or nothing b/c we are
dealing with fairly crucial information. However, I will look into
building savepoints into the class so that I'll have that option in
the future.
It seems like I've used savepoints or nested transactions in MSSQL in
the past (in stored procedures). I hope MySQL will support nested
transactions in future releases.
So, am I taking the best approach (at this point) for dealing with
transactions? I will basically have to evaluate every situation in the
program where a failure would occur and put in a $db-rollback();
call?
What about try/catch blocks? I'm not currently using them, but maybe
it would be the best way to handle exceptions when dealing with
multiple queries. If there's *any* query failure, explode!
Thanks!

RE: [PHP] php mysql live feed
Nameless,
I see someone mentioned the setTimeout(function, milliseconds) function for
JavaScript. I would also like to point out that you can use
setInterval(function, milliseconds) in order to have an event repeat at a set
interval. For instance, let's say you had a page laid out like so:
---
div id=blah
Text here
/div
---
You would want to add a script somewhere that would begin the interval in order
to update the div:
---
script type=text/javascript
function ajaxRequest()
{
// insert postback code here
document.getElementById(blah).innerHTML = ajax.responseText;
}
var t = setInterval(ajaxRequest(), 5000);
/script
---
This assumes that your XmlHttpRequest object is named ajax. Assigning the
interval to variable t ensures that you can clear the interval if you need to
(via clearInterval(t);).
I suppose innerText can be used instead of innerHTML, as well. I would
recommend using innerHTML only if you will be populating the div with HTML
code, however.
Hope this helps,

Subject: [PHP] php mysql live feed
Okay before i pull more hair out...
I am trying to use php to pull mysql data and refresh the mysql data
every say 5 seconds for like a live display of the database without the
screen reloading.
I want the data to refresh but not the screen. Ajax seems to hate me
because everything i have seen/read/tried is wrapped around ASP.NET or
requires a user interaction to invoke the query.
If you have example scripts or a good tutorial that actually works
where you can open a php script and the data changes on the page as the
database does and the screen does not refresh, and you don’t have to
onclick, onfocus, or onblur kind of thing. I would be in your debt

Todd
I want to thank you. You sent me thinking in the right direction to resolving
this issue. I now have successfully created a live Pika Card status GUI using
PHP, MYSQL, AJAX.
The key word in what you said was unique function. I was not thinking to write
a function. I was looking for the quick solve (php MySQL loop or something
stupid). Not only does this work flawless but it has surpassed all my
expectations of the gui.
Todd thank you again for your suggestions and you helped me allot.

You can use setTimeout() to delay a call to a Jabbascript function.
Remember that the second argument is milliseconds, and not seconds. Eg.
setTimeout('alert(Hello)', 1000);

Thanks for the help... :) one benefit of package managers is that they let you uninstall and reinstall easily. are you using yum or apt-get ? in your first post you included both the commands.. anyway, id just uninstall and reinstall it; should take 10 minutes or so. -nathan -- Rahul Computer Engineering and Systems Division.

Ok I removed mysql using yum remove mysql. But is there a special way to tell yum to install that version of mysql?

Rob,
A few years ago, I developed a full-on inventory management system
(with barcode printing and assignment, as well as scanning) and found
that with Code 39 I didn't have the issue, but when using UPC or some
other format, I often had to convert the code to string(). Then
insert the data into a CHAR or VARCHAR column, because to most
systems, INT 001234 is equal to INT 1234, but with more overhead,
which is then normally trimmed.

RE: [PHP] PHP/mySQL question about groups
You are correct, but that is what I meant by all columns (all those in the query, and therefore subject to the distinct). At this point different database engines work differently, without an order by, some will use the primary sequence, some will scan table space (in other words, without an order by [or group by], some engines will give you a performance hit). It's always good practice to write your queries to help your DB engine find an index.
