Cannot overwrite woocommerce functions

[RobertCrx]

Hello!
I am trying to replace the function ->

// Add card-img-top class to product loop
remove_action('woocommerce_before_shop_loop_item_title', 'woocommerce_template_loop_product_thumbnail', 10);
add_action('woocommerce_before_shop_loop_item_title', 'custom_loop_product_thumbnail', 10);
function custom_loop_product_thumbnail()
{
  global $product;
  $size = 'woocommerce_thumbnail';
  $code = 'class=card-img-top';

  $image_size = apply_filters('single_product_archive_thumbnail_size', $size);

  echo $product ? $product->get_image($image_size, $code) : '';
}

But it seems it doesn't work. I created another action function and added a priority of 5, I tried to remove action , but nothing happens. What should I do if I want to recreate the loop woocommerce structure ?
Thank you.

You're right, this function is not wrapped in the if (!function_exists. We can change this to:

// Add card-img-top class to product loop
if (!function_exists('custom_loop_product_thumbnail')) :
  remove_action('woocommerce_before_shop_loop_item_title', 'woocommerce_template_loop_product_thumbnail', 10);
  add_action('woocommerce_before_shop_loop_item_title', 'custom_loop_product_thumbnail', 10);
  function custom_loop_product_thumbnail() {
    global $product;
    $size = 'woocommerce_thumbnail';
    $code = 'class=card-img-top';

    $image_size = apply_filters('single_product_archive_thumbnail_size', $size);

    echo $product ? $product->get_image($image_size, $code) : '';
  }
endif;

While we are here, let's change custom_loop_product_thumbnail to bootscore_loop_product_thumbnail.

Thanks for reply!
While I was investigating , I discovered another problem..
When I try to call inside ajax wc_get_template_part('content','product') , all my custom actions are replaced again by the default parent actions

public function removeParentMethods()
    {
        add_action('wp_head', [$this, 'overwriteMethods']);

    }

    public function overwriteMethods()
    {
        // are replaced again
        remove_action('woocommerce_before_shop_loop_item_title', 'custom_loop_product_thumbnail', 10);
        remove_action('woocommerce_after_shop_loop_item_title', 'woocommerce_template_loop_price', 10);
        add_action('woocommerce_after_shop_loop_item_title', [$this, 'productLoopPrice'], 5);
    }

I don't tested yet if is good to call in head , but for now I think I will use this syntax and for the product loop , I will make a static function that recreate the product loop with everything I need.

  public static function renderWoocommerceProducts()
    {
        global $product;

        // Ensure visibility.
        if (empty($product) || !$product->is_visible()) {
            return;
        }
        ?>

        <div class="col-md-6 col-lg-3 col-xl-4">
            <div <?php wc_product_class('skeleton-loader card h-100 d-flex text-center', $product); ?>>
                <a href="<?php echo esc_url(get_the_permalink()); ?>"
                    class="woocommerce-LoopProduct-link woocommerce-loop-product__link">
                    <h2 class="woocommerce-loop-product__title">
                        <?php echo esc_html($product->get_title()); ?>
                    </h2>
                </a>
                <div class="card-body d-flex flex-column">
                    <div class="loop-product-wrapper">
                        <div class="loop-product-line"></div>
                        <div class="loop-product-prices">
                            <?php
                            echo '<del>' . (is_numeric($product->regular_price) ? wc_price($product->regular_price) : $product->regular_price) . '</del>';
                            echo '<ins>' . (is_numeric($product->sale_price) ? wc_price($product->sale_price) : $product->sale_price) . '</ins>'; ?>
                        </div>
                    </div>
                </div>
                <?php // add to cart and other stuff here
                do_action('woocommerce_after_shop_loop_item'); ?>
            </div>
        </div>
        <?php

    }

At the moment , I cannot use pull , because I'm working on a testing server that I don't have access to git modifications , but later on I will make a pull request if needed.
