  </tr>
</table>
</form>
 
 

when i implemented the above code.,

i got all the results perfectly.,

but in IE when i clear the cookies using the browser options i didnt get the cookies cleared and values are displayed in the corresponding fields.,

How can this possible., the cookies should get cleared right?

As pbmods already suggested, IE is showing you a cached version of the page. I'm going to say it again: you're not using PHP to delete the cookies, but the browser. Therefore, this isn't a PHP problem.

then what is the solution for this??

is there no way?

So have you tried refreshing the page manually? If you can't, remove the meta refresh in your code and try again.

Have you set your cookie expiration anywhere, like your php.ini file (if that is where it is defined)? Have you tried it on a different computer/different browser?

If you have a cookie which won't allow itself to be removed then you have pretty amazing cookie. Otherwise you will need to try a browser troubleshooting page.

Are the cookies going into the usual cookie place? As in where your cookies usually go?

Tried refreshing the page by both ways.,

No i didnt hav set my cookie to expire anywhere.,

and already tried with different computers and browsers.

and my cookie is going to the usual cookie place only.,
i m damn sure abt this.,

What is your cookie named? And just checking, the cookies from your site are the only ones not deleting? There are no other persistant cookies?

hi

my cookies alone are not deleted.,
i tried by using the link

http://www.labpixies.c om/campaigns/todo/todo.html

and this too shows the cached page when i tried by deleting the cookies through browser settings(IE).,

but if i press delete all instead of pressing delete cookies in browser options., i get the new page with all cookies deleted.


and one more question

is there a limit to set number of cookies??

i need to set upto 30 cookie variables.,

is it possible.,

firefox allows me to set more than 30 cookie variables.,

but IE allows only 20 cookie variables to be set., if i m setting next cookie variable then the first cookie variable i had set gets expired..,

but i'm in need to set about 20 to 30 cookie variables.,

is there any way??
