Post list on post.html not working

I want to show related posts on post.html page, filtered by current category, but for some reason is not showing anything...

Post.html:

<?php  
                        perch_blog_custom(array(
                                        'count'      => 10000,
                                        'template'   => 'proyectos.html',
                                        'sort'       => 'postDateTime',
                                        'sort-order' => 'DESC',
                                        'category' => perch_get('cat'),
                                        // I also tried this-------> 'category' => 'proyectos/'.perch_get('cat'),
                                    ));
                        ?>

You can't use PHP functions in an HTML template. If you need the result output within the template, you'll need to get the result out on the page and then pass it in.

Hi Raul, is there a 'cat' value to get in the querystring at this point? There would need to be for that to work.

You'll need to use perch_blog_post_categories to get the category(s) from the current post.

This helpful article from Clive Walker will help you:

Hi Simon, I am using this code

if (isset($_GET['cat']) && $_GET['cat']!='') {
      $cat = $_GET['cat'];
      $_SESSION['cat'] = $cat;
    }elseif (isset($_SESSION['cat'])){
      $cat = $_SESSION['cat'];
    }else{
      // default cat
      $cat = 'transporte';
    }
    PerchSystem::set_var('cat', $cat);

I tried but It didn't work as I adapted:

<?php  

                        //Get the categories for the current post 
                        $categories = perch_blog_post_categories(perch_get('s'), array(
                         'skip-template'=>true, ));

                        //The post may be in more than one category, so we need to loop through these and get the category slugs
                        if (count($categories)) {
                         $cat_slugs = array();
                         foreach($categories as $cat) {
                         $cat_slugs[] = $cat['catSlug'];
                         }

                        //Display two related posts, ordered by date, excluding the current post
                        perch_blog_custom(array(

                         'category' => $cat_slugs,
                         'sort' => 'postDateTime',
                         'sort-order'=> 'DESC',
                         'count'=> 10000,
                         'template'=> 'blog/proyectos.html',
                         ));
                         }

                        ?>

Going back to your original code, does this work?

<?php  
perch_blog_custom(array( 
'count' => 10000, 
'template' => 'proyectos.html', 
'sort' => 'postDateTime', 
'sort-order' => 'DESC', 
'category' => $cat,
)); 
?>

Ok, so that's obviously not a category you're after.

Can you show your whole page code now, as I am unsure of what's in there at this point.

Sorry for delay Simon, I've being out for two weeks. Here is the full code

<?php

      $lang = $_GET['lang'];
      $_SESSION['lang'] = $lang;
    }elseif (isset($_SESSION['lang'])){
      $lang = $_SESSION['lang'];
    }else{
      // default language
      $lang = 'es';
    }

    if (isset($_GET['cat']) && $_GET['cat']!='') {
      $cat = $_GET['cat'];
      $_SESSION['cat'] = $cat;
    }elseif (isset($_SESSION['cat'])){
      $cat = $_SESSION['cat'];
    }else{
      // default cat
      $cat = 'transporte';
    }

    PerchSystem::set_var('lang', $lang); // para blog multilang 
    PerchSystem::set_var('cat', $cat);
