Question

Basically I would like to create a function that will in turn create a multidimensional array based on another function. Here’s the format of the array I need to create (end result):

'options' => array (
        'one' => array (
            'label' => 'Option One',
            'value' => 'one'
        ),
        'two' => array (
            'label' => 'Option Two',
            'value' => 'two'
        ),
        'three' => array (
            'label' => 'Option Three',
            'value' => 'three'
        )
    )

This will need to be created by a function using another array that was created to store wordpress categories:

$categories = get_categories('hide_empty=0&orderby=name');
$wp_cats = array();
foreach ($categories as $category_list ) {
       $wp_cats[$category_list->cat_ID] = $category_list->cat_name;
}       

And here’s the code I wrote to try accomplish what I’ve described but couldn’t get it to work:

    function wcat2() {
    $i = 0;
    $categories = get_categories();
    foreach( $categories as $category ) {
        $i++;
        array (
        $i => array (
            $category->slug => $category->slug,
            $category->term_id  => $category->term_id
        ),
        );
    }
}

Any ideas of what I’m missing? Help would be much appreciated.

Update: Here’s an illustration of what I need:

Answer 1

Maybe something like:

function wcat2() {
    $out = array();
    $categories = get_categories();
    foreach( $categories as $category ) {
        $out[$category->term_id] = array(
            'label' => $category->slug,
            'value' => $category->term_id
        );
    }
    return array('options'=>$out);
}
print_r(wcat2());

Create a blank variable $out, loop through the categories and on each loop append a new array in the desired format. I’m not sure which is which in regards to the slug/term_id, so you might need to switch those.
