can not remove cookie on IE, But FF is fine

[heropage]

I use this to create a cookie

  setcookie('user_id','test', time() + 3600);  

Then I use this to remove the cookie.

  setcookie('user_id','', time() - 3600);  

In firefox, it works fine. But in Internet explorer 7. It doesn't work.

$user_id=$_COOKIE['user_id'];
print "user:".$user_id;

Any idea?

I found on my development server, it works fine.
But on live server, it's not working in IE.

Is there any issue with server setting?

After I reset my IE twice, it works now.
But I am not sure what cause this.

How about this one. I am writing a simple bit of code for a logout function when I noticed that my cookies were not being deleted. To test the problem I wrote this:

<?php
unset($_COOKIE["poo"]);
setcookie ("poo","x",time()[phone]);
setcookie ("poo","x",time()-1536000);
header( "Location:../poo.php");
exit;
?>

When I run logout.php and check for cookies in FF there is nothing there, but if I comment out the second line and run it again it creates the cookie as normal.

When I un comment the second line and run it again the cookie is not deleted.

Any ideas why ?

I'm at a complete loss - but sure it's something completely stupid.

Cheers in advance

i dont know if this is the correct method but i always just set a blank cookie for the same time as the original cookie. So if I use this to set the cookie:

setcookie ("poo","x",time()+10000);

then I use this to make it blank:

setcookie ("poo","",time()+10000);

It seems to work fine in both browsers for me 🙂

Thanks Matt, but that doesn't work either. Very strange, especially as there are people on this forum who can delete cookies in FF but not IE.

I know it works because this is code from a previous site I wrote which works.

Strange!!

And the soultions is...simple.

Include the domain in the setcookie command for creating and deleting and all is well.

setcookie ("poo","x",time()[phone],"domain.com");
setcookie ("poo","x",time()-1536000,"domain.com");
header( "Location:../poo.php");

Works a treat.
