I wrote a function to change Add To Cart button text for products on backorder.
woocommerce_product_single_add_to_cart_text works fine, but using woocommerce_product_add_to_cart_text crashes the page.
In the error log I see that it freezes class-wp-term.php.
Here's my function code:
function change_button_text_on_backorder() {
if (! is_admin()) {
global $product;
$qty = $product->get_stock_quantity();
$button_text = $product->add_to_cart_text();
if ( $qty < 1 && $product->backorders_allowed() ) { // backorders allowed?
$button_text = 'BACKORDER';
}
return $button_text;
}
}
add_filter('woocommerce_product_single_add_to_cart_text', 'change_button_text_on_backorder');
add_filter('woocommerce_product_add_to_cart_text', 'change_button_text_on_backorder');
I'm using WordPress 5.8, WooCommerce 5.6. Any suggestions why it crashes?
Your code contains some mistakes
$product is passed as an argument, so there is no need to use a global variable$product->add_to_cart_text() is also not necessary, as this is also passed as an argumentSo you get:
function filter_woocommerce_product_add_to_cart_text( $add_to_cart_text, $product ) {
// Get stock quantity
$qty = $product->get_stock_quantity();
// Backorders allowed?
if ( $qty < 1 && $product->backorders_allowed() ) {
$add_to_cart_text = __( 'Backorder', 'woocommerce' );
}
return $add_to_cart_text;
}
add_filter( 'woocommerce_product_add_to_cart_text', 'filter_woocommerce_product_add_to_cart_text', 10, 2 );
add_filter( 'woocommerce_product_single_add_to_cart_text', 'filter_woocommerce_product_add_to_cart_text', 10, 2 );
