php - Customize "Add to cart" button for a specific product category in WooCommerce

Question

This is my code:

    add_filter( 'woocommerce_product_single_add_to_cart_text', 'woo_custom_cart_button_text' );    // 2.1 +

function woo_custom_cart_button_text( $text ) {
    if( has_term( 'liners', 'product_cat' ) ){
        $text = __( ' ', 'your-plugin' );

          echo do_shortcode('<a href="#" class="popmake-923">Request а Quote</a>');
    }
    return $text;
}

I need to make function to replace the "Add to cart" button Url and Text for just one specific product category.

This button will trigger a Lightbox with a contact form and the text for this button will be: Request a Quote.

How can I make it work as expected?

Here is how it works actually on this link.

Answer 1

Updated: for 2 different product categories (2 different buttons)

A global and complete solution for your products from 'liners' product category:

1. If one of your products (in 'liners' product category) is not a variable product, you need first to replace the add-to-cart button in shop and archives pages by a simple button linked to the product.
2. In single product pages you need to remove add-to-cart button and quantities fields, to replace it by your custom button.

Here is that code:

// Replacing the button add to cart by a link to the product in Shop and archives pages
add_filter( 'woocommerce_loop_add_to_cart_link', 'conditionally_replacing_add_to_cart_button', 10, 2 );
function conditionally_replacing_add_to_cart_button( $button, $product  ) {

    $categories = array('liners','custom-classics');

    $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

    // For 'liners' product category
    if( has_term( $categories, 'product_cat', $product_id ) ){
        $button_text = __("View product", "woocommerce");
        $button = '<a class="button" href="' . $product->get_permalink() . '">' . $button_text . '</a>';
    }
    return $button;
}

// replacing add to cart button and quantities by your custom button in Single product pages
add_action( 'woocommerce_single_product_summary', 'conditionally_replacing_template_single_add_to_cart', 1, 0 );
function conditionally_replacing_template_single_add_to_cart() {
    global $product;

    $categories = array('liners','custom-classics');

    $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

    function custom_button_replacement(){
        global $product;

        $categories = array('liners','custom-classics');

        $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

        if( has_term( $categories[0], 'product_cat', $product_id ) )
            $class_id = "923"; // liners
        elseif( has_term( $categories[1], 'product_cat', $product_id ) )
            $class_id = "925"; // custom-classics
        else $class_id = ""; // none

        // set below your custom text
        $button_text = __('Request а Quote', 'woocommerce');

        // Output your custom text
        echo '<a href="#" class="popmake-'.$class_id.' button">'.$button_text.'</a>';
    }

    // Only for 'liners' and 'custom-classics' product categories
    if( has_term( $categories, 'product_cat', $product_id ) ):
        // For variable product types
        if( $product->is_type( 'variable' ) ){
            // Removing add to cart button and quantities
            remove_action( 'woocommerce_single_variation', 'woocommerce_single_variation_add_to_cart_button', 20 );

            // The button replacement
            add_action( 'woocommerce_single_variation', 'custom_button_replacement', 20 );
        }
        else // For all other product types
        {
            // Removing add to cart button and quantities
            remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );

            // The button replacement
            add_action( 'woocommerce_single_product_summary', 'custom_button_replacement', 30 );
        }
    endif;
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested and works for all product types (simple, variable…). You will get (example):
