I want to create a variabele for both my_product_price and my_product_id. I tried the following code but it doesn't work. What am i doing wrong?

// Function for slider Price
    function add_royalslider_product_price($m, $data, $options) {
    
    $m->addHelper('my_product_price', function() use ($data) {

           $_product = wc_get_product( $data->ID );

           return $_product->get_price();
           
    } );

}
    add_filter('new_rs_slides_renderer_helper','add_royalslider_product_price', 10, 4);

// Function for slider ID
    function add_royalslider_product_id($m, $data, $options) {
    
    $m->addHelper('my_product_id', function() use ($data) {

           $_product = wc_get_product( $data->ID );

            return $_product->get_id();
           
    } );

}
    add_filter('new_rs_slides_renderer_helper','add_royalslider_product_id', 10, 4);

   Hello,

   The code seems to be correct, does it work for you when you try to return just string? For example {{my_product_price}}:

   function add_royalslider_product_price($m, $data, $options) {
   
       $m->addHelper('my_product_price', function() use ($data) {
           return "TEST PRICE";
       } );
   
   }
   add_filter('new_rs_slides_renderer_helper','add_royalslider_product_price', 10, 4);

   Hi Dmitry,

   It doesn't work when I try to return a string. It doesn't show the page content at all.

   When I only use the first part (slider price) it works. But as soon as I add the Id part it stops working.

   Make sure that you don't have syntax errors such as extra symbols between lines. Also, you can add multiple helpers in one filter like this:

   function add_slider_variables($m, $data, $options) {
   
       $m->addHelper('my_product_price', function() use ($data) {
           return "TEST PRICE";
       } );
   
       $m->addHelper('my_product_id', function() use ($data) {
           return "TEST ID";
       } );
   
   }
   add_filter('new_rs_slides_renderer_helper','add_slider_variables', 10, 4);

   This works with the strings, but as soon as i add return $_product->get_price(); and return $_product->get_id(); it crashes.

   What am I missing?

   EDIT: Thank You Dmitry ! It works
