woocommerce_update_product action – fire only once for every product update

Which workaround is there for making the woocommerce_update_product action fire only once?

I've read that it fires twice because it needs to save once internally to retrieve an ID for images/variation saves.

But from a developer experience, this is really not what most need, I guess.

The only workaround I've found so far is to add the action and remove it in the hook directly:

add_action('woocommerce_update_product', 'my_product_update', 10, 2);
function my_product_update($product_id, $product){
    remove_action('woocommerce_update_product');
    // We'll get here only once!
}

However, this breaks when trying to do bulk edits, making it so that the hook only fires for the first product (because it gets removed afterwards!).

Which other way is there to work around this issue?

Thanks!

Solution 1:

Maybe using WordPress Transient can help.

add_action('woocommerce_update_product', 'my_product_update', 10, 2);
function my_product_update($product_id, $product) {

    $updating_product_id = 'update_product_' . $product_id;
    if ( false === ( $updating_product = get_transient( $updating_product_id ) ) ) {
        // We'll get here only once! within 2 seconds for each product id;
        // run your code here!
        set_transient( $updating_product_id , $product_id, 2 ); // change 2 seconds if not enough
    }
}

Solution 2:

A simpler solution would be to set a $_POST variable and check at the start of the function.

add_action( 'woocommerce_update_product', 'my_action', 10, 1 );
function my_action(){
   if( isset($_POST['action_performed']) ){
      //Prevent running the action twice
      return;
    }
   
   // do you stuff here

   $_POST['action_performed'] = true;
}
