okay so im trying to enter a dynamic meta tag for the facebook api

  • 0

okay so im trying to enter a dynamic meta tag for the facebook api and some wierd things are happnening.

here is how im getting the value

$id = $_GET['id'];

$id = intval($id);

and this is where i input it.

 <meta property="og:url" content="http://blaze-craft.com/matt/gag.php?id=<?php echo $id ?       >" />
<meta property="og:image" content="http://blaze-craft.com/matt/get.php?id=<?php echo $id ?>" />

But it is always outputing the value as 0 even when its not 0. Also when i echo it out anywhere else on the page it works?

any help would be great thanks! 😀

Okay iv just seen in the source code it is being set 

<html>
<head>
<title>YourGag - Gag</title>
<meta property="og:title" content="MyGag - Gag" />
<meta property="og:type" content="activity" />
<meta property="og:url" content="http://blaze-craft.com/matt/gag.php?id=2" />
<meta property="og:image" content="http://blaze-craft.com/matt/get.php?id=2" />
<meta property="og:site_name" content="YourGag" />
<meta property="fb:admins" content="1254694731" />
<link rel="stylesheet" href="style.css" type="text/css" />
</head>
<body>

but when im use the facebook debugger its saying that there is a 0 there instead of a 2!

seriosly wierd!

    Have you tried debugging the value of $_GET['id'] before attempting to cast as an int?

    Per the documention (intval):

    Return Values

    The integer value of var on success, or 0 on failure. Empty arrays
    return 0, non-empty arrays return 1.

    So $_GET['id'] is either an empty array or cannot be returned as an integer value.
