Let’s say we have a tag array that was populated from a text file:

$tags = array( 'a', 'b', 'c' );

And now we want to check if a specific tag is in both arrays:

if ( in_array( 'a', $tags ) ) {

$response = 'Tag found';

} else {

$response = 'Tag not found';

}

As we expected, $response = ‘Tag found’. But if we search for ‘b’, $response = ‘Tag not found’ even though we can see very clearly that the value ‘b’ exists in the array $tags.

What’s the solution?

The key to the solution lies in the fact that the array $tags was populated from a text file. Text files can contain all sorts of hidden characters that in_array() can pick up when comparing parameters. The fix is simple. Before passing the $tags array to in_array(), trim up each of the array values like so:

$tags = array_map( 'trim', $tags );

This took me a good 3 hours to figure out. I hope you found this article in less time.

Oh great. I’ve gone full-nerd.

I would make one improvement. Instead of hard-coding the <meta> tag to add your app id, I would insert the following into your functions.php file:

/* Add meta info required for Facebook comments */
add_action( 'wp_head', 'channeleaton_facebook_comments' );
function channeleaton_facebook_comments() {
?>
	<meta property='fb:app_id' content='YOUR APP ID' />
<?php
}

That code should make it a bit easier for those of you using child themes.
