Disable specific cart item quantity fields based o

Question

In woocommerce I am using Hide “remove item” from cart for WooCommerce product category answer code and I would like to disable the cart quantity field too, avoiding customer to change the item quantity to zero.

Is that possible? Any track on this will be appreciated.

Answer 1

The following code will remove the "quantity field" from cart for items from a specific product category (that you will define in the 2nd function):

// Custom conditional function that checks for categories (including parent)
function has_product_categories( $product_id, $categories ) {
     // Initializing
    $parent_term_ids = $categories_ids = array();
    $taxonomy        = 'product_cat';

    // Convert categories term names and slugs to categories term ids
    foreach ( $categories as $category ){
        if( is_numeric( $category ) ) {
            $categories_ids[] = (int) $category;
        } elseif( term_exists( sanitize_title( $category ), $taxonomy ) ) {
            $categories_ids[] = get_term_by( 'slug', sanitize_title( $category ), $taxonomy )->term_id;
        }
    }

    // Loop through the current product category terms to get only parent main category term
    foreach( get_the_terms( $product_id, $taxonomy ) as $term ){
        if( $term->parent > 0 ){
            $parent_term_ids[] = $term->parent; // Set the parent product category
            $parent_term_ids[] = $term->term_id; // (and the child)
        } else {
            $parent_term_ids[] = $term->term_id; // It is the Main category term and we set it.
        }
    }
    return array_intersect( $categories_ids, array_unique($parent_term_ids) ) ? true : false;
}

add_filter( 'woocommerce_quantity_input_args', 'hide_cart_quantity_input_field', 20, 2 );
function hide_cart_quantity_input_field( $args, $product ) {
    // HERE your specific products categories
    $categories = array( 'clothing' );

    // Handling product variation
    $product_id = $product->is_type('variation') ? $product->get_parent_id() : $product->get_id();

    // Only on cart page for a specific product category
    if( is_cart() && has_product_categories( $product_id, $categories ) ){
        $input_value = $args['input_value'];
        $args['min_value'] = $args['max_value'] = $input_value;
    }
    return $args;
}

Code goes in function.php file of your active child theme (or active theme). Tested and works.

Note: If you are using also your other answer code, the first function is already defined and doesn"t have to be twice on your function php file…
