iterating through $_POST

[bioTINMAN]

I have a form which has checkboxes named check1, check2, check3 and so on, the number being decided by another php code. When this form submits values to another php code, how do i get it to search for all those checks at once? can I use a wildcard like

 

$HTTP_POST_VARS['check%'];

 

I did try ofcourse, but it didnt work out.

You need to put your check in a loop. The following code snippet assumes you know the maximum number of checkboxes some how.

<?php
for ($i=1;$i<=$maxchecks;$i++)
    if (isset($_POST['check' . $i])) {
//
//  do something
//
    }
?>

 

If you have control over the script that creates the form, changing the names of the checkboxes to be an array would greatly simplify the code:

<?php
foreach ($_POST['check'] as $cb) {
//
// do something
//
}
?>

ill go for the second one. I should have changed all those checkboxes to arrays, but it was easier to do it the way I did. But now ill find a way around. So there is actually no way to use any wildcards in the field name afterall, is there?
