Hi all, this is probably stupidly easy but I'm struggling.
I am trying to understand why cookies only appear to be readable when a
web page is retrieved by *typing the url into the browser's address
box* but NOT when the same page is accessed *via a link from another
page*. I probably don't fully understand the mechanics of an HTTP
request...
Example:
The first page sets a persistent cookie:
<?php
$value = 'something';
setcookie("Test Cookie", $value, time()+(24*365* 3600));
?>
and contains a link - <a href="cookie_te st.php?">Link to cookie
test</a>
The second page [cookie_test.php] contains the following code:
<?php
print "COOKIE DATA: <br />";
foreach ( $_COOKIE as $cookie_name =$cookie_value ) {
print "$cookie_na me = $cookie_value <br />";
}
?>
When a) viewing cookie_test.php , using either Firefox 2.0 or IE7, via
the link from page one, the cookie data does not print out. But b) by
entering cookie_test.php into the address box and pressing return, this
causes the browser to display the cookie contents.
PHP Version 4.3.10
Could I have an explanation please and how do I retrieve cookie data in
case (a) ?
Thanks for your help... 1 1546

Hey 4site,
Sounds like everything should work fine, but the browsers might be
caching cookie_test.php without the information on it. Have you tried
completely refreshing the page after cookie_test.php loads empty? You
might also check out the manual for header() as there is a good example
for stopping browsers from caching pages.
Good luck, Blayde This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I did try to find the answer to this before posting, so this isn't a
knee jerk reaction.
What I am trying to accomplish is to have a script that opens a
cookie, reads a value, and then use a switch/case to take action based
on that value in the cookie. I want to set the cookie manually, so I
don't need setcookie(). I see that in PHP it...
