Update form on countdown

[mrt003003]

Hi there i was wondering if its possible to have a count down timer (for say 5 mins) that when it reaches 0 a form is updated..

 

<?php
// set countdown timer for 5 mins 
$countdown = '300' 

if ($countdown == '0'){

update the form somehow? }?>


<form id="form1" name="form1" method="POST" action="<?php echo $editFormAction; ?>">
<input name="hiddenField" type="hidden" value="<?php echo $row_query['somedata']; ?>" />
<input type="submit" name="Submit" value="Submit" />
</form>

 

I'm a bit of a noob so any help would be ace.

 

Thanks

Like a page refresh?

If so use headers. Else explain

No i was thinking more like, at the end of the countdown timer something would replace the function of the submit button and so no submit button would be needed.

That would probably require AJAX, PHP is a server-side language.

Hmm is there no way to do it in php alone? Something like:

 

$countdown = '300' 

if ($countdown == '0'){

if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) {
  $updateSQL = sprintf("UPDATE table SET something = '1'");

  mysql_select_db($database_swb, $swb);
  $Result1 = mysql_query($updateSQL, $swb) or die(mysql_error());  }?>

No, PHP is server side.
