I need to include some of my products in all subcategories of category Auto. For example - product Wheel must be in all subcategories of Auto, e.g. Audi, BMW, Mercedes, etc. How to do this without manual choosing of all subcategories?

I need to include some of my products in all subcategories of category Auto. For example - product Wheel must be in all subcategories of Auto, e.g. Audi, BMW, Mercedes, etc. How to do this without manual choosing of all subcategories?

• categories
• taxonomy
• woocommerce-offtopic

• When i select( check on checkbox ) parent category i need to check all the subcategories belongs to that parent category. I can’t able to find this option in Woocommerce product filter plugin. I tried the above solution but it doesn't seems to work.. can you please tell me what is 'categorychecklist' ID? – Sathishkumar Commented Jun 14, 2019 at 10:49

1 Answer 1

(1) Paste below code to your functions.php file

function my_enqueue() {
    wp_enqueue_script( 'my_custom_script', get_template_directory_uri() . '/js/myscript.js' );
}
add_action( 'admin_enqueue_scripts', 'my_enqueue' );

(2) Create myscript.js file and paste below code in it and place the file in 'yourtheme/js/' folder.

jQuery(document).ready(function () {

    jQuery('#categorychecklist').prepend('<input type="checkbox" id="selectall"><label for="selectall">Select all subcategories.</label><hr>');

    jQuery('#categorychecklist [type="checkbox"]:not(#selectall)').on('change', function () {
        if(jQuery('#selectall').is(':checked')) {
            jQuery(this).parent().parent().find('ul.children [type="checkbox"]').prop('checked', true);
        } else {
            jQuery(this).parent().parent().find('ul.children [type="checkbox"]').removeAttr('checked');
        }
    });
});

(3) Done - now selecting your parent category will automatically select child categories if Select all subcategories checkbox is selected on product edit page.
