Quick fix for where a meta tag is duplicate

[arnonzamir]

Great plugin. Slick and functional.

I had a website with some post that have duplicate meta tags with similar keys. Strange and unwanted, but it was there.
It may be useful for someone so here's my quick-fix:

public static function linkRewriteFieldsExtract($post, $fieldName) {
        $postMeta = get_post_meta($post->ID);
        if(!isset($postMeta[$fieldName]))
            return '';	

	//deal with duplicate keys by taking the value of the first
        if (is_array($postMeta[$fieldName])) {
			$value =  $postMeta[$fieldName][0];	
		} else {
			$value = implode('', $postMeta[$fieldName]);
        }
        $value = sanitize_title($value);
        return $value;
    }

Hello,

Thank you for the contribution. Indeed, it is an another case I didn’t considered. Soon I will review code and make some tests and release a new version.
