Ecommerce Shopify WordPress Discussion

display a preview of a pdf file

I use wordpress and a CPT to display with ACF Pro blocks a gallery. This gallery is populate with pdf files. When I display the gallery into a page, I would like to display the PDF preview of the first page, as an image. For now I have this into may function, but it doesn't display the preview. What is wrong with this php code? if ($pdf_attachments) { echo '<div class="galerie-pdf">'; foreach ($pdf_attachments as $pdf) { // Affichez un aperçu echo '<a href="' . esc_url($pdf['url']) . '" target="_blank" class="un_pdf">'; echo '<img decoding="async" src="' . esc_url($pdf['url']) .' " alt="PDF" height="87" width="60" title="' . esc_html($pdf['title']) . '" />'; echo esc_html($pdf['title']); echo '</a>'; } echo '</div>'; }
