collectionKey question

Stephen Meehan · Jan 15th 2020

Hi,

I'm using a list and detail setup to display posts from two collections , it works well but I'd like to be able to use the collectionKey within the template.

If I can expose it I intend to use it in the ahref, like this:

website.com/case-studies/post-name/
website.com/posts/post-name/

Using define('PERCH_DEBUG', true); I can see this in the Debug message

SELECT collectionID, collectionTemplate FROM perch3_collections WHERE (collectionKey='Posts' OR collectionKey='Case Studies')

If I can expose the collectionKey somehow, I'm hoping it'll be possible to manipulate it with PHP to make it slug friendly and use PerchSystem::set_var to make it visible to my perch template.

hus_hmd has created a very neat perch add-on which solves this problem.

Here's the code I'm using to output items from multiple collections

Code

perch_collection(['Posts', 'Case Studies'], [
'template' => '_post/post--listing.html',
'sort'=>'postDateTime',
'sort-order'=>'DESC',
// Install pipit add-on first
'each' => function($item) {
$item['collectionKey'] = pipit_get_collection_key_for($item['_id']);
return $item;
}
]);

Within my post--listing.html template I added <perch:content id="collectionKey" urlify>, this takes the collectionKey and converts it into a slug friendly value.

The post--listing.html template can now display a unique ahref based on its collection name (collectionKey).
