Facebook Open Graph Meta WordPress Plugin

Today I wanted put Facebook Open Graph Protocol meta tags on my blog. I searched for a long time and I was not able to get a simple and working plugin for WordPress. So I decided to write my own. If you want use this plugin please make sure you replace the tag [REPLACE] with appropriate values.

function getTheExcerptCustom( $post_id, $auto_generate = true, $length = 50, $ellipsis = ' [...]' ) {
	$post = get_post( $post_id );
	$excerpt = $post->post_excerpt;
	if ( !$excerpt && $auto_generate ) {
		$content = strip_tags( strip_shortcodes( $post->post_content ) );
		$content = preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", " ", $content);
		$words = explode( ' ', $content );
		if ( count( $words ) > $length ){
			$excerpt = implode( ' ', array_slice( $words, 0, $length ) ) . $ellipsis;
		}else{
			$excerpt = $content;
		}
	}
	return $excerpt;
}

function insertFBOpenGraphMeta() {
	$postImage = false;
	print "\n\n";
	if(is_singular()){
		$attachmentDetails = &get_children( "numberposts=1&post_type=attachment&post_mime_type=image&post_parent=" . get_the_ID() );
		if(!empty ($attachmentDetails)){
			$attachmentDetails = array_shift($attachmentDetails);
			$postImage = array_shift(wp_get_attachment_image_src($attachmentDetails->ID,'thumbnail'));
		}
		print "\n";
		print "\n";
		print "\n";
		if(!empty ($postImage)){
			print "\n";
		}
		print "\n";
	}else{
		print "\n";
		print "\n";
		print "\n";
		print "\n";
		print "\n";
	}
	print "\n";

}
