[SOLVED] Validation for a dynamic form

[coffejor]

Hello all,

 

I have an order form that is built dynamically from my products database and would like to create a dynamic validation and form processor.

 

I have created a good validation scheme by hardcoding the names of the fields from the orderform, an example is as follows

 

$two_a = $_POST['PROD_cub_bear_patch_3x3_4'];

$two_b = $_POST['PROD_cub_bear_patch_special_10'];

$two_c = $_POST['PROD_cub_club_patch_3'];

 

The names like PROD_cub_bear_patch_3x3_4 are stored in fields in a database corresponding to their appropriate product and can be easily retrieved. I would like to make a while loop that goes through the database and creates the variable dynamically from the post based on whats in the database.

 

A possible solution is as follows

 

$result = @mysql_query('SELECT * FROM products WHERE category AND status="1"');

while ($row = mysql_fetch_array($result)) {

$name = $row['name'];

echo '$'.$name.' = $row[/''.$name.'/'];';

}

 

*NOTE: $name is the name of the product field that is stored in the database

 

I'm not sure how to make this work and would be really appreciative of any input/insight that any of you may have.

 

Thanks in advance.

Take a look at the http://zigmoyd.sourceforge.net/man/ums.php#validate

[redbullmarky]

dynamic variables can be constructed using braces after the $, so:

 

<?php
$animal = 'dog';

${$animal} = 'woofs';

echo $dog; // output: woofs
?>

That worked perfectly. Thanks, I owe you one!
