Here is a fully functional and tested custom function that will display on shop pages and archives woocommerce pages, a custom add-to-cart (text + link), for logged in customers that have already bought the products:
add_filter( 'woocommerce_loop_add_to_cart_link', 'customizing_add_to_cart_button', 10, 2 );
function customizing_add_to_cart_button( $link, $product ){
$bought = false;
if( is_user_logged_in() ){
$customer_orders = get_posts( array(
'numberposts' => -1,
'meta_key' => '_customer_user',
'meta_value' => get_current_user_id(),
'post_type' => 'shop_order', // WC orders post type
'post_status' => 'wc-completed' // Only orders with status "completed"
) );
// Going through each current customer orders
foreach ( $customer_orders as $customer_order ) {
$order = wc_get_order( $customer_order->ID );
// Going through each current customer order items
foreach($order->get_items() as $item_id => $item_values){
if($item_values['product_id'] == $product->id){
$bought = true;
break;
}
}
}
}
if($bought){
// ==> SET HERE YOUR
// CUSTOM ADD TO CART text and link
$add_to_cart_url = site_url('/custom_link/');
$button_text = __('View now', 'woocommerce');
} else {
$add_to_cart_url = $product->add_to_cart_url();
$button_text = $product->add_to_cart_text();
}
$link = sprintf( '<a href="%s" rel="nofollow" data-product_id="%s" data-product_sku="%s" data-quantity="%s" class="button product_type_%s">%s</a>',
esc_url( $add_to_cart_url ),
esc_attr( $product->id ),
esc_attr( $product->get_sku() ),
esc_attr( isset( $quantity ) ? $quantity : 1 ),
esc_attr( $product->product_type ),
esc_html( $button_text )
);
return $link;
}
This code goes in function.php file of your active child theme (or theme) or also in any plugin file.
If you want to customize the add-to-cart button for some specific products, or an array of products or a product category, you will have to add a condition by specific product, this way (this is an extract of the code above):
if($bought){
// for the product ID 45 (for example)
if( $product->id == 45 ){
$add_to_cart_url = site_url('/custom-link/product-45/');
$button_text = __('View now product 45', 'woocommerce');
}
// for the product ID 64 (for example)
if( $product->id == 64){
$add_to_cart_url = site_url('/custom-link/product-64/');
$button_text = __('View now product 64', 'woocommerce');
}
// for an array of product IDs (for example)
$product_ids = array(89, 92, 124);
if( in_array( $product->id, $product_ids ) ){
$add_to_cart_url = site_url('/custom-link/some-products/');
$button_text = __('View now some products', 'woocommerce');
}
// for a product category
// set here your product category ID, slug or name (or an array of values)
$category = 'My category'; // Here a category name for example
if( has_term( $category, 'product_cat', $product->id ) ){
$add_to_cart_url = site_url('/custom-link/my-category/');
$button_text = __('View now from my category', 'woocommerce');
}
} else {
$add_to_cart_url = $product->add_to_cart_url();
$button_text = $product->add_to_cart_text();
}
