Show default imagen when the product image is broken in Prestashop 1.7

[cobrax13]

Hello,

After doing an import of more than 25000 products with the Prestashop importer in a 1.7 installation, I find that I have 5000 products whose images are broken. The importer tried to upload images but they did not exist.  I have been trying to make the image show me a default image when the image is broken directly, I almost have it, but when trying to use the file_exists function I have discovered that it needs the absolute URL and I can only get the relative one. Does anyone have any idea how to do it?

I put the code that I have edited in /themes/child-classic-theme/templates/catalog/_partials/miniatures/product.tpl

 

  <article class="product-miniature js-product-miniature" data-id-product="{$product.id_product}" data-id-product-attribute="{$product.id_product_attribute}" itemscope itemtype="http://schema.org/Product">
    <div class="thumbnail-container">
      {block name='product_thumbnail'}
        {if $product.cover}
     <!-- Code I have inserted -->
        {assign var='coverImage' value=Product::getCover($product->id)}
	    {assign var='coverImageId' value="{$product->id}-{$coverImage.id_image}"}
        {assign var='urlImagen' value="{$link->getImageLink($product.link_rewrite, $coverImageId)}"}
      <!--urlImagen is the relative path to the image, but I need the absolute path oh the image because "file_exits" function uses that path -->
      <!-- Code that checks if the image exists, when I get this to work the change would be in the code below -->
        {if (file_exists($urlImagen))}
        Existe imagen
        {else}
        No existe imagen
        {/if}
      <!-- End Code I have inserted -->
          <a href="{$product.url}" class="thumbnail product-thumbnail">
            <img
              src="{$product.cover.bySize.home_default.url|default:'{$urls.img_prod_url}img/p/es-default-cart_default.jpg'}"
              alt="{if !empty($product.cover.legend)}{$product.cover.legend}{else}{$product.name|truncate:30:'...'}{/if}"
              data-full-size-image-url="{$product.cover.large.url}"
            />
          </a>
        {else}
          <a href="{$product.url}" class="thumbnail product-thumbnail">
            <img src="https://alcasum.es/tienda2020/img/p/es-default-cart_default.jpg" />
          </a>
        {/if}
      {/block}

Thanks for all

Can you please know, know how to solve this problem ??
I theme Drama, and I can't find product-list.tpl anywhere
how to solve the problem du PS 1.7.7.4
please help me how and what to modify?
possible that a CMS like PS does not take into account something so IMPORTANT FUNDAMENTAL I find it really as children who do not take into account, considering that PS is used for thousands of products in csv is ... absurd!
