I want to add an additionall custom “Add to cart button” on the single product page conditionally using this code:
add_action( 'woocommerce_product_meta_end' , 'add_to_cart_custom', 10 ); function add_to_cart_custom() { $mamut = get_field('mamut'); $stockstatus = get_post_meta( get_the_ID(), '_stock_status', true ); $id = $product->get_id(); if ($mamut) { echo 'Send request'; }elseif(!$mamut and $stockstatus === 'outofstock'){ echo 'Send request - Mamut'; }elseif(!$mamut and $stockstatus === "instock" ) { echo 'Add to cart'; } }
This variable is field from ACF $mamut = get_field('mamut');
However when I put this code into my functions.php
file, the single product page crash
I am using theme Twenty nineteen and Elementor Pro.
I’ve tried to remove actions and then add different one but it doesn’t work. Also I tried to make shortcodes and enter them using Elementor , but then shortcodes displayed as text.

Answer
- Your using
$product->get_id();
while$product
is not defined - You could use
$product->get_stock_status();
instead ofget_post_meta( get_the_ID(), '_stock_status', true );
So you get
function add_to_cart_custom() { global $product; // Is a WC product if ( is_a( $product, 'WC_Product' ) ) { // Get field - function from ACF plugin, plugin must be actived for this $mamut = get_field( 'mamut' ); // Get stock status $stock_status = $product->get_stock_status(); // If value exists if ( $mamut ) { echo 'Send request'; } elseif( ! $mamut && $stock_status === 'outofstock' ) { echo 'Send request - Mamut'; } elseif( ! $mamut && $stock_status === 'instock' ) { echo 'Add to cart'; } } } add_action( 'woocommerce_product_meta_end' , 'add_to_cart_custom', 10, 0 );
