JS Confirm blocking referrer 1

[cian]

Hi guys,

I'm working a php bookmark type script. I have a confirm alert on each link delete button, when confirmed the link gets deleted. Problem is the script processing the deletion needs to read the referrer to refer back to that page after the link is deleted.

Problem: It won't work in IE. It can't seem to check the referrer so returns an error. But it will work in Moz, NS & Opera.
The JS i'm using is below. Do you think it can be changed to also work in IE or should I forget about it? I really do need a confirm on the delete button and the delete script cannot point directly to a named file but must check for a referrer. Any ideas?

<a href=&quot;javascript:if (confirm('Delete link?')) {location.href='process.php?action=delete&id=123';}&quot;>Delete</a>

Any help greatly appreciated!!

I assumed it was a javascript problem otherwise the browser version would have no effect?
It's only IE that it won't work in, other browsers I have tested work fine.

If it was a PHP problem then it wouldn't work in any browser.

i had that doubt becase:
>>script processing the deletion needs to read the referrer

the script to delete will be a PHP, and whta does this referrer mean? u want to go to the previous page after deleting the link???

Yep, to break it down.

On (for example) bookmarks.htm you click &quot;delete link&quot; and confirm, it goes to process.php which is the script that deletes the link from the database. Process.php also reads the referrer and then redirects back to that page.
My guess is that somehow the confirm js is confusing IE.

Or am I way off the mark here??

In this case yes but I am using a generic delete script which must delete from any number of pages, otherwise it would be very easy

I don't have the script with me but I am referring with basically (syntax may not be correct cos it's off the top of my head but it works(except IE)):

header('Location: ' . $HTTP_SERVER_VARS["REFERER"]');

if that is breaking ur head, use javascript:
<?
//ALL php code
?>
<script>
locatio.href=history.back()
</script>

Btw, this WILL work in IE if I remove the javascript confirm function, sorry I should also have mentioned that at the start.

Thanks, i'll try that tonight. Question is, will it reload the page, the page must be displayed with the relevant link removed.
