Posting Using Category Slug

  1. I'm using this code below to post into specific categories using the category ID… and it works great… what I'm wondering is if there's a way to make it grab and use the category "slug" instead?

    I have, literally, over 1,000 categories. And when I make a new one (or a new set of them) referencing the category ID takes forever. If I could simply type in the slug it would make life oh-so-easy!

    Here's the code...

    /* Gravity Forms Posting */
    add_action('gform_post_submission', 'gform_add_greenmy_home', 10, 2);
    function gform_add_greenmy_home($entry, $form){
        if(!rgar($entry, 'post_id'))
        $post_id = rgar($entry, 'post_id');
        $valid_cat_ids = get_greenmy_home_ids();
        $cat_ids = array();
        foreach($form['fields'] as $field){
            if(strpos($field['cssClass'], 'add_greenmy_home') === false)
            foreach($entry as $key => $value){
                if(intval($key) != $field['id'] || !in_array($value, $valid_cat_ids))
                $cat_ids[] = (int) $value;
        wp_set_object_terms($post_id, $cat_ids, 'greenmy_home', false);
    function get_greenmy_home_ids(){
        $categories = get_terms('greenmy_home', 'hide_empty=0');
        $cat_ids = array();
        foreach($categories as $category)
            $cat_ids[] = $category->term_id;
        return $cat_ids;
    function print_greenmy_home($array){
        echo '<pre>';
        echo '</pre>';

  2. Hi Noel,

    It doesn't look like it'd take much to convert this to slugs rather than IDs. This bit from the get_greenmy_home_ids() function would need to be updated like so:

    foreach($categories as $category)
        $cat_ids[] = $category->slug;

    You might consider renaming the variables through out to indicate that you are using slugs now (ie $cat_ids would be come $cat_slugs).

    You would also want to make sure you update the values of your custom category field in GF to use the slugs as well.

  3. I had tried that...

    Is it because all of the categories are in custom taxonomies?
    I'm betting yes.

  4. Try using print_r() to echo out the $categories variable to see if you're successfully retrieving any categories. If so, check and make sure the slug property exists for these categories.
