loop through dynamic $_POST keys

[jmack159]

hi there.

i have a script right now that prints out nicely info on performances from a db. i want to add a select next to each entry to change the performance status. the selects have a name attribute of the form: "stat_change$perform_id". im a bit confused on the processing side, i know i need to loop through the $POST array to get the new status and the perform id, but how to only loop through selects and not any other form data? the tough part is that the keys in the $POST would by dynamic. i was thinking about something with reg exp. but that is an area im not to familiar with:rolleyes:. like i could check to see that is is of the form "stat_change*", or somethins. is this is a reasonable method/approach? any ideas would be great! thanks!

You could make the field names array elements:

<form action="<?php echo $_SERVER['SCRIPT_NAME']; ?>" method="post">
<?php
for($perform_id = 1; $perform_id <=5; $perform_id++)
{
?>
<p>
<input type="text" name="stat_change[<?php echo $perform_id; ?>]" size="20">
</p>
<?php
}
?>
<p>
<input type="submit" value="Submit">
</p>
</form>
<?php
if(!empty($_POST['stat_change']))
{
   foreach($_POST['stat_change'] as $key => $value)
   {
      echo "<p>\$stat_chenge[$key]: $value</p>\n";
   }
}
?>
