I am trying to add dynamic Facebook og meta tags to my Wordpress site. I am adding them to single.php instead of the usually recommended functions.php file because I have code below that for a Facebook app I've created that needs to execute every time someone views an individual blog post because it then posts to their Facebook timeline that they've read that particular post. I don't want to use a plugin because some of my plugins used to conflict with each other and it was a mess to get that straightened out. My biggest problem is that I need the og:url tag to be dynamic, though the og:title, og:description, og:image, etc. should be as well. Here is the code I have at the top of my single.php file:
EDIT: HERE IS THE WORKING CODE I AM NOW USING. THANKS FOR EVERYONE'S HELP:
<?php
$params = array();
if(count($_GET) > 0) {
$params = $_GET;
} else {
$params = $_POST;
}
// defaults
if($params['type'] == "") $params['type'] = "picture";
if($params['locale'] == "") $params['locale'] = "en_US";
if($params['description'] == "") $params['description'] = "Visit Internet LOLs for the funniest humor on the web! :)";
?>
