Hooks

Using hooks you can edit data throughout the plugin when it is process, displayed or just stored.

Reading properties

By default reading all properties have an hook available.

// Model name can be either 'product' or 'variant', the key is the slug of the custom field.
'eduframe_{$model_name}_get_{$prop}'

You can then add a custom hook that runs when that field is called upon.

add_filter( 'eduframe_product_get_cost', function ( $price ) {
    return $price . ' in Euros';
} );

Assuming the value of cost is 10 the value will return in Euros instead.

global $product;
$field = $product->get_cost();
echo $field;

'10 in Euros'

You can disable hooks when getting values by setting the view as 'edit' like so:

global $product;
$field = $product->get_cost( 'edit' );
echo $field;

'10'

Common hooks

Use case:
Don't show course locations on the website that have the string archived in the name since these course_locations are not used anymore.

The code below achieves this by adding a filter before the course_location_widget makes a query:

add_filter( 'eduframe_course_location_widget_query_args', 'remove_archived_locations' );

function remove_archived_locations($query) {
	$query['meta_query'] = array(
        'relation' => 'OR',
		array(
			'key' => 'name',
			'value' => 'archived', 
			'compare' => 'NOT LIKE'
		)
    );
		
	return $query;
}
