Output category list inside array

Question

I need to output information about each of my post categories in this array, but I'm having trouble figuring out how.

I need to output each category as an array (See examples) under the values option with the following information;

'label' => 'CATEGORY NAME' 'values' => 'CATEGORY ID'

array(
    'param_name'  => 'ids',
    'settings'    => array(
        'multiple' => true,
        'values'   => array( 
            // EXAMPLE
            array( 'label' => 'Abrams', 'value' => 1, 'group' => 'category' ),
            // EXAMPLE
            array( 'label' => 'Brama', 'value' => 2, 'group' => 'category' )
        ),
    ),
),

I've tried using a foreach get_categories() loop inside the array but apparently PHP doesn't like that.

Any help would be greatly appreciated.

Answer 1

Try something like the following. Notice that the hide_empty argument is set to false.

$args = array(
    'orderby' => 'id',
    'hide_empty'=> false,
);

$cats = get_categories($args);

foreach ($cats as $cat) {
    // Your code to populate new array here
}

And then assign your newly created array to values.
