Template for Blog postTag Template Tag

I can't use php in a template though, so would I need to include a layout file to do this?

I'm still not getting it I'm afraid. This is what I have done:

/blog/index.php

<?php
  $tags = perch_blog_post_tags(perch_get('s'));
  PerchSystem::set_var('tags', $tags);
  perch_blog_recent_posts(10);
?>

post_in_list.html

<perch:blog id="tags" />

This doesn't output anything :(

Still getting nothing I'm afraid Drew. I think the problem is that it needs to be called from within the template else it won't work.

Do you mean in a post URL? As in "post.php?s=2015-12-17-our-first-blog-post"

Any ideas why? Just to clarify I am calling this from the main blog index.php page rather than the post page itself so would the post slug not become available until cycling through perch_blog_recent_posts(10)?

Sure Drew, see below:

/blog/index.php:

<?php
$tags = perch_blog_post_tags(perch_get('s'), false, true);
PerchSystem::set_var('tags', $tags);

perch_blog_recent_posts(10);
?>

post_in_list.html:

<perch:blog id="tags" />

Yeah, that's what I was trying to say. Hence why I asked you if I could call this from within the post_in_list.html template file? It seems clear to me that it should be called from within the loop, not outside as you previously seemed to suggest.

Drew McLellan said:

You'd need to use an each callback for that.

'each' => function($item) {
   $item['tags_html'] => perch_blog_post_tags($item['postSlug'], false, true);
   return $item;
},

Sorry Drew, I'm even more confused now, where am I putting this code in my files? Plus, am I supposed to replace 'each' as this doesn't look like valid PHP? In fact if I put this in my /blog/index.php page I get a syntax warning (Parse error: syntax error, unexpected '=>' (T_DOUBLE_ARROW)). And what is 'tags_html'?

I'm afraid you are going to have to explain this in dumb terms and break it down as to how and where to use this - sorry!

Thanks, Mike.

I'm getting a syntax error with this code: Parse error: syntax error, unexpected '=>' (T_DOUBLE_ARROW) on this line:

$item['tags_html'] => perch_blog_post_tags($item['postSlug'], false, true);

I assume this should be

$item['tags_html'] = perch_blog_post_tags($item['postSlug'], false, true);

It still doesn't work anyway and shows this error in diagnostics now:
