How can I show related collection items with block contents in a page? - General Discussions

Mar 25th 2020

Been a while since I used Perch Runway.
Anyone able to help shed some light on this? I am trying to use a related collection, which is working but the blocks within the related items are not showing....

here is the gist:

	<perch:related id="faqs" collection="FAQ's" label="FAQ's" sort="custom" >
	<details class="expandingBlock // application-notes__item">
	<summary class="expandingBlock__title // application-notes__title"><perch:content id="question" type="text" label="Question" required="true" title="true" /></summary>
	<div class="expandingBlock__content">
	<perch:template path="content/blocks/content-primary.html" />
	</div>
	</details>
	</perch:related>

view raw related_faqs.html hosted with ❤ by GitHub

```

<perch:related id="faqs" collection="FAQ's" label="FAQ's" sort="custom" >

<perch:template path="content/blocks/content-primary.html" />

</div>

</details>

</perch:related>

```

If I stick a <perch:showall> then I get the following back, so it looks accessible.
The question field is pulling through ok for each item. but none of the blocks.....

As far as I know you can't render perch:blocks inside perch:related tags.

A workaround could be to render it outside of the template (e.g. in a callback function with the each option):

PHP

perch_collection('Some Collection', [

'each' => function($item) {

if(isset($item['faqs'])) {

$item['faqs_html'] = perch_collection('FAQs', [

'template' => 'faqs/some_template.html',

'filter' => '_id',

'match' => 'in',

'value' => implode(',', $item['faqs'])

], true);

}

return $item;

}

]);

Display More

And output the rendered HTML inside your template:

HTML

<perch:content id="faqs_html" html>

From what I'm aware of you can't access repeater or blocks namespaces inside the related namespace.

Your best option is to get the related content from a separate template and store the response as a variable and then output that in your current template.

Code

$collection = perch_collection('Example', [

    'skip-template' => true,

    '_id' => perch_get('id')

]);

$collection[0]['catHTML'] = perch_categories([

    'set' => 'categorySet',

    'filter' => 'id',

    'match' => 'eq'

    'value' => $collection[0]['related_id'],

    'template' => 'template_with_blocks'

, true]);

perch_template('current_template, $collection);

Display More

Then you should be able to access the HTML with

Code

<perch:content id="catHTML" html="true" />

There will most definitely be mistakes with what I've provided above, but the idea should work.
