I want to display a popup by CodeLights on every WC product. For this I put this in my child theme's function.php

add_action( 'woocommerce_product_meta_end', 'childReview' );
function childReview() {
  echo do_shortcode('[cl-popup size="l" title="Click!" btn_label="Headline" btn_bgcolor="#006982" btn_color="#ffffff" overlay_bgcolor="rgba(0,105,130,0.75)" title_textcolor="#006982" content_textcolor="#006982"]Some Content goes here
[/cl-popup]');
}

This works absolutely fine. Now I want to add the product's image to each popup. What I tried is to put this into the content part of the shortcode, so behind "Some content goes here":

<img src="<?php the_post_thumbnail_url(); ?>" alt="" width="300" height="300" />

Unfortunately, that doesn't work at all. The popup works but the images src just remains as <?php the_post_thumbnail_url(); ?>, so the image doesn't appear.

Does anyone have some advice for me?

Thanks a lot and BR, Dario

I think you're just printing your function as a string, try concatonating: 

add_action( 'woocommerce_product_meta_end', 'childReview' );
function childReview() {

  global $post;

  echo do_shortcode('[cl-popup size="l" title="Click!" btn_label="Headline" btn_bgcolor="#006982" btn_color="#ffffff" overlay_bgcolor="rgba(0,105,130,0.75)" title_textcolor="#006982" content_textcolor="#006982"]<img src=" ' . wp_get_attachment_url ( get_post_thumbnail_id( $post->ID ) ) . '"/>
[/cl-popup]');
}

  • Hi @MrBizle, thanks for your answer. I got a step further with it: the URL of the thumbnail is now being displayed. But not in the popup but before the generated button. And it's a URL that is being diplayed, not the image... Commented Aug 8, 2016 at 14:19
  • Cool! Are you sure you can put HTML in that shortcode? Sounds like might be stripping it out. Have you got a link bud? Commented Aug 8, 2016 at 14:23
  • Hi @MrBizle, hum, I'm sure that I can use HTML in that shortcode. Images, Headlines,... no problem. Not sure about PHP though...You can find the blue button with popup here: wohngeschwister.de/produkt/bowl-nor-blau. The generated URL appears above the button. Thank you so much for helping!

  • It doesn't appear to be rendering the src URL at all 🤔 Commented Aug 8, 2016 at 14:30

    the_post_thumbnail_url doesn't take a post ID as the parameter. Try wp_get_attachment_url ( get_post_thumbnail_id( $post->ID ) ) instead. Commented Aug 8, 2016 at 14:43
