Bug in “Custom Fields for WooCommerce” by Addify

Couldn’t find any way to contact them for support directly… the whole woocommerce plugin ecosystem kinda suck when it comes to support/bug signaling.

Anyway… Custom Fields for WooCommerce throws a

Uncaught TypeError: jQuery(…).select2 is not a function

on every page that is not a woocommerce page (product/cat/cart/checkout).
Pretty annoying.

I edited line 110 “jQuery(‘.af_cf_multiselect_custom’).select2();” to have a timeout and check if the script exist and eventually throw a warn.

setTimeout(() => {
    // Initialize select2 with retry logic
    function initSelect2WhenReady(attempts = 0, maxAttempts = 20) {
        if (typeof jQuery.fn.select2 !== 'undefined') {
            jQuery('.af_cf_multiselect_custom').select2();
        } else if (attempts < maxAttempts) {
            // Try again after 100ms, up to 20 times (2 seconds total)
            setTimeout(() => initSelect2WhenReady(attempts + 1, maxAttempts), 100);
        } else {
            console.warn('Select2 library not available after waiting');
        }
    }
    
    initSelect2WhenReady();
}, 1200);
