BUG: php warning when postmeta is empty

buzink · #1 Oct 12, 2009, 06:53 AM

In bfa_postinfo.php on line 16 the implode function is called to make a string out of the meta_values array. When the array is empty, this function returns an ugly php warning that is visible on my blog . This happens when a meta-value is called that is empty for that post.

To fix this, change

Code:

// Callback function for post meta replacement^M
function meta_values($matches) {
        $meta_key = $matches[1];
        // "get_post_custom_values" returns an array. Turn it into a string, separated by commata
        
                $meta_values = implode(", ", get_post_custom_values($meta_key));
        
        return $meta_values;
}

to

Code:

// Callback function for post meta replacement^M
function meta_values($matches) {
        $meta_key = $matches[1];
        // "get_post_custom_values" returns an array. Turn it into a string, separated by commata
        if (get_post_custom_values($meta_key)) {
                $meta_values = implode(", ", get_post_custom_values($meta_key));
        } else {
                $meta_values = "";
        }
        return $meta_values;
}
