How to Override Component Properties in October CMS Using PHP

To access a specific component, you can use the following methods:

$this->page->components[ 'componentName' ];

// Or just
$this->componentName;

It allows you to use method setProperty().

In the following example we change the recordsPerPage property of the collection after the component is initialized:

[collection blogPosts]
handle = "Blog\Post"
recordsPerPage = 5
==
<?php
function onStart () {
	// Overrides posts per page property from 5 to 10.
	$this->blogPosts->setProperty( 'recordsPerPage', 10 );
}
==
{% for post in blogPosts %}
	{{ post.title }}
{% endfor %}

If you initialize the component from a partial, you can retrieve the component and change its property this way:

$this->controller->findComponentByName( 'blogPosts' )->setProperty( 'recordsPerPage', 10 );
