More great stuff. Thanks. Think it's all working now but repeating table update by date in CC callback just to be sure.

Update. Yeh that works, although really not sure why. I could understand if it wasn't running the PHP but it was. In fact, if I make a pure PHP page to update one record it only works on refresh although the page wouldn't show if the PHP wasn't running!
Wierd, anyway it works, ta very much.
Last thing, though, the above solution works because a race condition exists whereby the source of your iFrame is set before the document that contains it is ready. The code above alleviates that race condition in a naive way, by inserting a second's delay into proceedings to allow the document to finish loading before setting the source of the IFrame that is a constituent part of the document. There's no guarantee that precise delay will work for every user, though. Still, it at least identifies what the problem was.
Now that you know for sure what problem is, the best solution to ensure that this works for all users, if you're using jQuery, is to put the following code on your page:
Code:<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { $('#offers').attr("src", "captcha/getoffers.php"); }); </script>
Code:<body onload="setHiddenIFrameSource();">

Possibly a document ready issue. Try putting this script somewhere on your page:
Code:<script type="text/javascript"> setTimeout('setHiddenIFrameSource();', 1000); function setHiddenIFrameSource() { document.getElementById('offers').src = "captcha/getoffers.php"; } </script>

PHP MySQL problem
Got a hidden iframe in a webpage that invokes a PHP script:
<iframe id="offers" src="captcha/getoffers.php" etc
The php populates the iframe with a list of current (ie where expiry date is >= current date) offer codes when the page is opened and it works fine. However, I am also trying to update the table with any expired statuses:
if expired etc....
$id = mysql_result($result,$i,"id");
$r = mysql_query("UPDATE offers SET status=-1 WHERE id=$id");
That works when I refresh the page but not when I open it, although echo statements show it is going through the loop on open, so can't see why the query line is not working. Any great ideas? Cheers.Tags: None
