Hey there I’m trying to get SL to work with featured images loaded into my custom theme. I’m trying to follow the documentation and also other forum posts I’ve seen on the subject but I keep getting php errors with the code I’m trying to use.

Either there’s something super simple I’m missing or I’m trying to implement the code completely wrong. Here’s what I’ve got:
```
		   
<div class="imgbox">	
     <?php
	$url = get_the_post_thumbnail_url('full');
	$image = the_post_thumbnail();
	$content = '<a href="' .$url. '">' .$image. '</a>'
            if ( function_exists('slb_activate') ) {
	         $content = slb_activate($content);
            }
         echo $content;
       ?>
</div>
```
Any help and advice would be greatly appreciated!

Hi, the the_post_thumbnail() template tag immediately outputs the post thumbnail image to the browser (documentation). As a result, nothing is stored in the $image variable.

If you want store the image tag in a variable instead, you need to use get_the_post_thumbnail() (documentation).

I’ve also added a full example for linking the post thumbnail to SLB’s manual activation documentation for future reference.

Worked perfectly! And thank you so much for adding that to the docs!

This is probably what I’m looking for too
I’ve installed SLB and activated it
But I don’t understand where to add the code
In the documentation it says “Code should be added to post loop.” but where do I find this
Ei what file should be altered and where do I find it
I don’t want to change the wrong file
And where in the file should this code be added

@mikeyswede The code needs to be added to the theme file(s) that you want to add a linked featured image to. The specific files depends on your selected theme, so contacting the theme’s developer is recommended if you’re not sure which file(s) to edit.

Here are some resources regarding working with a theme’s post loop:
- The Loop | Theme Developer Handbook | WordPress Developer Resources
- What is a Loop in WordPress? | WPBeginner
