if php cookie set, show code...

[adrianle]

Hi all.. I need to figure out this little snippet right quick.. seems like it should be easy enough to do, but I'm flailing here...

 

I need to have a blurb that checks to see if a cookie of a specific name is set, and if it is - then show a certain line of code (basic href link).. but if the cookie is NOT set, to show a different line of link code.

 

HELP!?!!?

[trq]

if (isset($_COOKIE['name'])) {
  // code
} else {
  // other code
}

[adrianle]

Believe it or not, I actually have that part! What I don't have is how to add in regular HTML code in the spaces in between the statements, marked in your comment by "// code"

[trq]

Two ways....

 

<?php
if (isset($_COOKIE['name'])) {
  echo '<a href="foo.php">foo</a>';
} else {
  echo '<a href="foo.php">foo</a>';
}
?>

 

or

 

 

<?php
if (isset($_COOKIE['name'])) {
?>
  <a href="foo.php">foo</a>
<?php
} else {
?>
  <a href="foo.php">foo</a>
<?php
}
?>

ok, I tried that too and all I see is the 'else' chunk of the code.. and I think I know why.. the script HTML I have in the first chunk has single ticks in it.. and it's interfering with the PHP perhaps...

[adrianle]

I put this in and I ONLY see the chunk after the 'else' even if the cookie is set:

  <?PHP

if (isset($_COOKIE["April09"])){

?>

<a href="p20090419show.php"><img src="archive.gif" width="35" height="48" border="0"></a>

<?PHP

}

else

{

?>

Cookie not set

<?PHP   

}

?>

[trq]

Then the cookie is not being set.

Post the code you are setting the cookie with. Note that if you set the cookie on the same page it will not be available until a page reload.

[adrianle]

This sets the cookie:

 

<?php

setcookie ('April09', 'confirmed', time() + (60*60*48));

?>

I put this in and I ONLY see the chunk after the 'else' even if the cookie is set:

  <?PHP

if (isset($_COOKIE["April09"])){

?>

<a href="p20090419show.php"><img src="archive.gif" width="35" height="48" border="0"></a>

<?PHP

}

else

{

?>

Cookie not set

<?PHP   

}

?>

 

I could be wrong but won't escaping out of PHP each time like that cause ALL the html to be processed?

 

If you do print_r($_COOKIE); what do you get?

[trq]

You would be wrong. It is still only conditionally sent.

Good to know

[adrianle]

So.. any final thoughts on why this is happening for me?

Why not check the documentation for setcookie and read common problems associated, and check out the extra parameters.

 

Also , physically checking for the cookie's existence would help to check function.

hi oni-kun... I was hoping Thorpe could continue his previous thread of help.. thanks though

There's absolutely nothing you've given us to help you with, that's why he started going off-topic. Your code is completely correct and should work (under almost any circumstance) unless it is a problem with your server, such as, your cookie is being invalidated because of paths as mentioned by the other parameters you could set with  the cookie.

[adrianle]

well, that's actually more than I've gotten from others on this topic, so thanks.. I appreciate the confirmation and suggestion..

[crabfinger]

<?php
   var_dump($_COOKIE);
?>

 

Post what that tells you.

[adrianle]

It gives me this (which looks right to me?)

 

array(1) { ["April09"]=> string(9) "confirmed" }

[crabfinger]

Well if that is what is being ouput then the only thing that I can think of is that it is a problem with isset() and that can't be right. But you could try it without escaping from php

 

<?php
        var_dump($_COOKIE["April09"]);
        echo '<br / >';
if(isset($_COOKIE["April09"])) {
	echo '<a href="p20090419show.php"><img src="archive.gif" width="35" height="48" border="0"></a>';
}
else {
	echo 'Cookie not set';
}
?>

This all actually works beautifully if it's in a php page all by itself. For some reason, when I implement it on the page where it's meant to show, it fails and only shows the code after "else"... any thoughts on what might prevent the isset portion to be functional?

[adrianle]

For any interested.. I figured it out.  Probably an elementary mistake really..

 

anyways, the test files that always worked were in the same directory as the file setting the cookie, and the page calling/checking the cookie was in a different directory.

If you would have looked at the documentation as mentioned more than one time..
