Replace add to cart button with a custom button on WooCommerce - php

Question

I would like to replace the 'Add to cart' button for a specific product category and when product type isa a 'simple product'.
I would like to do that on the page where I can see all the products (shop and archive pages) and in single product pages.
The code bellow just hide my add-to cart buttons from all post of my product category:
function western_custom_buy_buttons(){
$product = get_product();
if ( has_term( 'categ1', 'product_cat') ){
// removing the purchase buttons
remove_action( 'woocommerce_after_shop_loop_item', 'woocommerce_template_loop_add_to_cart' );
remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );
remove_action( 'woocommerce_simple_add_to_cart', 'woocommerce_simple_add_to_cart', 30 );
remove_action( 'woocommerce_grouped_add_to_cart', 'woocommerce_grouped_add_to_cart', 30 );
remove_action( 'woocommerce_variable_add_to_cart', 'woocommerce_variable_add_to_cart', 30 );
remove_action( 'woocommerce_external_add_to_cart', 'woocommerce_external_add_to_cart', 30 );
}
}
add_action( 'wp', 'western_custom_buy_buttons' );
How can I achieve that? Any help please.

Here is a complete working solution that will replace all add-to-cart buttons for your defined product category and simple products only, by a custom "read more" button.
This code is tested and works on WooCommerce versions from 2.6.x to 3.0+:
// Replacing add-to-cart button in shop pages and archives pages
add_filter( 'woocommerce_loop_add_to_cart_link',
'quantity_inputs_for_woocommerce_loop_add_to_cart_link', 10, 2 );
function quantity_inputs_for_woocommerce_loop_add_to_cart_link( $html, $product ) {
// WooCommerce compatibility
if ( method_exists( $product, 'get_id' ) ) {
$product_id = $product->get_id();
} else {
$product_id = $product->id;
}
if ( has_term( 'categ1', 'product_cat', $product_id ) && $product->is_type( 'simple') ) {
// Set HERE your button link
$link = get_permalink($product_id);
$html = ''.__("Read More", "woocommerce").'';
}
return $html;
}
// Outputing a custom button in Single product pages (you need to set the button link)
function single_product_custom_button( ) {
global $product;
// WooCommerce compatibility
if ( method_exists( $product, 'get_id' ) ) {
$product_id = $product->get_id();
} else {
$product_id = $product->id;
}
if ( has_term( 'categ1', 'product_cat', $product_id ) ) {
// Set HERE your button link
$link = '#';
echo ''.__("Read More", "woocommerce").'';
}
}
// Replacing add-to-cart button in Single product pages
add_action( 'woocommerce_single_product_summary', 'removing_addtocart_buttons', 1 );
function removing_addtocart_buttons()
{
global $product;
// WooCommerce compatibility
if ( method_exists( $product, 'get_id' ) ) {
$product_id = $product->get_id();
} else {
$product_id = $product->id;
}
if ( has_term( 'categ1', 'product_cat', $product_id ) )
{
#### Removing the add-to-cart button ####
## Simple products
remove_action( 'woocommerce_simple_add_to_cart', 'woocommerce_simple_add_to_cart', 30 );
## Other products types
// remove_action( 'woocommerce_grouped_add_to_cart', 'woocommerce_grouped_add_to_cart', 30 );
// remove_action( 'woocommerce_variable_add_to_cart', 'woocommerce_variable_add_to_cart', 30 );
// remove_action( 'woocommerce_external_add_to_cart', 'woocommerce_external_add_to_cart', 30 );
// remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );
// remove_action( 'woocommerce_single_variation', 'woocommerce_single_variation_add_to_cart_button', 20 );
#### Adding a custom replacement button ####
## Simple products
add_action( 'woocommerce_simple_add_to_cart', 'single_product_custom_button', 30 );
## Other products types
// add_action( 'woocommerce_grouped_add_to_cart', 'single_product_custom_button', 30 );
// add_action( 'woocommerce_variable_add_to_cart', 'single_product_custom_button', 30 );
// add_action( 'woocommerce_external_add_to_cart', 'single_product_custom_button', 30 );
// add_action( 'woocommerce_single_product_summary', 'single_product_custom_button', 30 );
// add_action( 'woocommerce_single_variation', 'single_product_custom_button', 20 );
}
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
