Cookies in PHP

[demsley]

Again feeling a bit of an idiot for having to ask this but I'm trying to work with Cookies and having problems.

 

Code should work AFAICS but no;

 

------------------------------------------

<?php

//Check and Increment Cookie

if(!isset($_COOKIE['Counter'])) {

echo "top section

";

$Counter = $_COOKIE['Counter']+1;

setcookie("Counter", $Counter );

echo "Setting Cookie to " . $Counter . "

";

}

else {

echo "Cookie not set";

setcookie("Counter", "1" );

$Counter = 1;

}

?>

<?php

// Print an individual cookie

echo $_COOKIE["Counter"];

echo $HTTP_COOKIE_VARS["Counter"];

 

// Another way to debug/test is to view all cookies

print_r($_COOKIE);

?>

 

 

 

<?php

// Print individual cookies

echo "You have visited " . $Counter . " times ";

 

 

?>

 

-------------------------------------

Any ideas would be gratefully received.

 

Cheers

Your if !isset is running the first section if the cookie is NOT set, and the else if it IS set. So they're backwards. Get rid of the !

BTW unless you buffer you cant output/echo until you set your cookies. Any *output* ends the chance to set cookies so remove/move the echo's after the SetCookie.

Normally an error would be in the logs for that.

Thanks for the responses, I've taken out the echos I'd put in but it doesn't work still. I'm feeling very stupid at this stage and know there's something I've missed - but what it is I have no clue!

 

<?php

//Set Cookie

if(isset($_COOKIE['Counter'])) {

$Counter = $_COOKIE['Counter']+1;

setcookie("Counter", $Counter );

}

else {

setcookie("Counter", "1" );

$Counter = 1;

}

?>

 

 

<?php

// Print individual cookies

echo "You have visited " . $Counter . " times ";

 

 

?>

Your Doctype is classed as output so you need to move this to after the cookie code above the xml line...

Yep the php code for cookies needs to literally be the first thing at the top of the file.
