Getting the following php error when trying to add a new post:

Warning: array_pop() expects parameter 1 to be array, boolean given in /home/mysite/public_html/blog/wp-content/themes/mytheme/functions.php on line 675

Here is the function:

function glossary_term_permalink($post_link, $post, $leavename, $sample) {
    if (false !== strpos($post_link, '%recipe_cat%')) {
        $glossary_letter = get_the_terms($post->ID, 'recipe_cat');
        $post_link = str_replace('%recipe_cat%', array_pop($glossary_letter)->slug, $post_link);
    }
    return $post_link;
}

Any idea what the issue is and how to resolve?

get_the_terms() will return a boolean false under some circumstances:

A post with no terms assigned gives a false result, not an empty array.

It sounds like that is what is happening. You need to check that $post_link = to ensure that it is the type you expect before trying to use it.

  • How do you check $post_link =? – frshjb373 Apr 2 '15 at 14:56
