template variables not passing

I am trying to send a custom variable to template page, below is my code.

pages/detail.php

    PerchSystem::set_var('custom_cat', 'collection');

    perch_content_custom('Collection', array(
      'page' => '/collection',
      'template' => 'collection/collections_detail.html',
      'filter' => 'slug',
      'match' => 'eq',
      'value' => perch_get('s'),
      'count' => 1,
    ));
    print_r(PerchSystem::get_vars());

content/collection/collections_detail.html page content

<perch:content id="custom_cat" />

I don't get any value in template. I am however getting value in print_r

I made sure "custom_cat" id was unique in the template.

<perch:showall /> shows "custom_cat" and the value correctly.

Can we see your template? If it's there in showall then it should be available.

Are you using repeaters or blocks and not bringing the top level variable into scope?

It's scoping.

Use scope-parent="true" on your perch:categories tag and then reference it with parent.custom_cat

I think you'll need to use a perch:category tag in that context. showall will help with this again.

I finally got it to work. Here is the solution

<perch:category id="custom_cat" />

<perch:content id="custom_cat" /> does not work if i am within category loop

Thanks Drew, perch:showall was very helpful
