Question

I use session values to set the content of facebook meta tag :

<meta property="og:title" content="<?php print $_GET['p']; ?>"/>

when I view source of the website the html appears like this :

<meta property="og:title" content="Alex Atalla"/>

which means it is successfully filled the value of session value in the content of title meta tag.

But when I use facebook debugger it says that :

Object Missing a Required Value:    Object at URL 'http://www.palestinianz.com/' of type 'website' is invalid because a required property 'og:title' of type 'string' was not provided.

what is the problem ?

Answer 1

Set a default value

if(!isset($_GET['p'])){
$value = 'default value';
}else{
$value = $_GET['p'];
}

<meta property="og:title" content="<?php echo $value; ?>"/>

The default value will be there on your home page OG
