Perch Blog — related posts from same category

Hi Drew,

Just done that, although still appear to be getting the same error. I've also just tried deleting all my posts and re-adding some new ones to each category

The array print_r are exactly as they come out.

My post page in it's entirety looks like:

<?php include('../perch/runtime.php'); ?>
    <?php 
        # get the post
        $post = perch_blog_custom(array(
              'filter'        => 'postSlug',
              'match'         => 'eq',
              'template'   => 'post.html',
              'value'         => perch_get('s'),
              'skip-template' => 'true',
              'return-html'   => 'true',
          ));

        # set up the variables
        $title       = $post['0']['postTitle'];
        $description = strip_tags($post['0']['excerpt']);

        # use the variables in the array value 
        perch_page_attributes_extend(array(
            'description'    => $description,
            'og_description' => $description,
            'og_title'       => $title,
            'og_type'        => 'article',
            'og_author'      => 'https://www.facebook.com/myfbpagename',
        ));

        perch_layout('header.blog', array(
            'title'           => perch_blog_post_field(perch_get('s'), 'postTitle', true) ,
            'blog' => true,
        )); 
    ?>

    <div class="post">

        <?php perch_blog_post(perch_get('s')); ?>

        <div class="post__right">
            <?php perch_layout('sidebar.blog'); ?>
            <?php
                //Get the categories for the current post 
                $categories = perch_blog_post_categories(perch_get('s'), array(
                       'skip-template'=>true, ));
                print_r($categories);

                //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[] = $cat['catSlug'];
                    print_r($cat);
                 }
                }

            ?>
        </div>

        </article>

        </div>

  </div> 


<?php perch_layout('footer'); ?>

Yeh me too. I will keep working away. Like you said though I've been through this a million time and everything looks fine - like it should work.

The only way I managed to get

perch_blog_custom(array( 
     'template'=> 'blog/post_in_list_related.html',
     'count'=> 2,
     'section'=> 'news',
     'filter' => 'postSlug',
     'match' => 'neq',
     'value' => perch_get('s'),
     'category' => $cat_slugs,
     'sort-order'=> 'RAND'
  ));

Is to change

$categories = perch_blog_post_categories(perch_get('s'), array('skip-template'=>true));

to

$categories = perch_blog_post_categories(perch_get('s'), true);

and I then see two stories from either category. Switch is back to the previous and I see nothing being output again. But causes the error:

Array
(
    [type] => 2
    [message] => Invalid argument supplied for foreach()
    [file] => /var/www/sitename/news/post.php
    [line] => 47
)

Should I able to to see catSlug in the showall output for the post?

Ill try make a fresh project this weekend in order to test this on a project where everything is set back to default and try track down what's happening from there. It must be something I've done within the project files for the blog that is causing this.

Just quick one - would using a set of categories under a set called 'news' rathern than 'blog' be a problem?
