[SOLVED] cookies

[dan2684]

Hello all,

 

I've added this to my product page:

 

setcookie("lastViewed",$_GET['prodId']);

 

...but it's not setting the cookie!

 

Any ideas?

 

Thanks,

 

Dan

If you want to cookie to remain after you close the browser, you need to set a time duration.

[dan2684]

Sorry, I've tried it with a time duration, and I've never closed my browser.

example:

 

cookie will expire in 1 hour:

setcookie("lastViewed", $_GET['prodId'], time()+3600);

 

Make sure you set the cookie before the tag.

mm, cookies.

 

so have you tried turning error reports on?

[dan2684]

no, haven't tried error reports - how do I do that?

[Maq]

Put this at the top of your script:

 

ini_set ("display_errors", "1");
error_reporting(E_ALL);

[revraz]

How do you determine the cookie is not being set?

 

Have you confirmed your $_GET variable?

[dan2684]

Maq- no errors

revraz - because I'm trying to echo it out on another page

[Maq]

You do something like:

 

if (isset($_COOKIE["lastViewed"]))
  echo "Last product_id viewed: " . $_COOKIE["lastViewed"] . "!
";
else
  echo "You have never viewed a product!
";
?>

 

?

[dan2684]

Yup - I know. The cookie isn't there.

 

Does that fact that it's running locally make a difference?

 

I know that sometimes things like mail() don't work until I make it live.

 

ie. are there settings in Apache that I can change?

If you want help, provide both the code that sets it and the code that reads it.

 

We can only guess at the problem if you don't provide enough info.

[dan2684]

Apologies for not being clear.

 

Product page:

setcookie("lastViewed",$_GET['prodId'],time()+3600);

 

Homepage:

echo $_COOKIE["lastViewed"];

 

[Maq]

There must be an external factor.  Does $_GET have a value?

 

I just tried:

 

setcookie("lastViewedTEST", 45,time()+3600);
echo $_COOKIE["lastViewedTEST"];
?>

 

And it echoed out 45...

 

Maybe you should post all the relevant code.

[revraz]

If you are using sub domains, make sure you use the domain switch when you set the cookie.

 

Also, look at your cookies in the cookie folder, do you see it being created there?

[dan2684]

I've just checked my cookies folder - it IS there and it has the correct value.  It's just not echoing out...

 

what's also weird is that it echoes out on the page where I set the cookie, but not the homepage.

[revraz]

setcookie("lastViewed",$_GET['prodId'],time()+3600, "/");

[dan2684]

I really didn't know you had to put it in the same directory!

 

Thank you revraz - you are a genius :-)
