WP woocommerce change "Proceed to checkout" buttons URL

the best way is the woocommerce hooks

Try to use this code (put it in your functions.php theme file).

add_filter( 'woocommerce_get_checkout_url', 'my_change_checkout_url', 30 );function my_change_checkout_url( $url ) {   $url = "your checkout url ";   return $url;}

You can customize it by adding some conditions to change the checkout url

for example:

add_filter( 'woocommerce_get_checkout_url', 'my_change_checkout_url', 30 );function my_change_checkout_url( $url ) {    $allowed_countries = array('FR');    $customer_country = WC()->customer->get_default_country();    if( !in_array( $customer_country , $allowed_countries ) ) {        $url = wc_get_page_permalink( 'other-checkout' );    }    return $url;}

It should be available at below path
