Set post terms by term id

Question

I'm trying to add post to custom terms within a custom taxonomy. Not sure if I'm tackling this right. So far we have the custom taxomony 'warehouse', and the custom term 'Old Stock'.

Problem is that when I try to add the term to the post using the term_id then it creates a new term with the id as a name. Here is the code I'm using:

//add new product
    $id = @wp_insert_post(array(
        'post_title' => $name,
        'post_content' => $desc,
        'post_status' => 'publish',
        'post_parent' => $parent,
        'tax_input' => array(
            array(
                'warehouse' => $parent
            ))
        ), true);

    //set terms
    wp_set_object_terms($id, array($parent), "warehouse");

As you can see I've tried adding the term_id as 'post_parent' as 'tax_input' and also using 'wp_set_object_terms'

If the term_id was 25, then the above would create a new term called "25"! Instead of sticking the post into the term with an id of 25.

Any help would be appreciated, cheers

Answer 1

When dealing with this, it turned out that the $parent var had to be casted as an int. Looking at the function wp_set_object_terms, it tests the param $parent with is_int(). The var $parent was coming from $_POST which was sent though http post using ajax.

Somewhere along the way, probably on the javascript side, my int $parent was being casted as a string. I'm presuming a new line character or something was being added to the var thus making php think it was a string.

Solution was then to cast the var $parent as an int like so: (int)$parent

So changing the last line to

wp_set_object_terms($id, (int)$parent, "warehouse");

Solved the problem ;)
