Programmatically assign read permissions

    Hi,

    I am building functionality where pages are created programmatically when certain steps are taken (this part is working fine).

    Is it possible to assign read permissions on a page to a particular group programmatically?

    Here’s what I have so far. Note that the page and the group’s slugs are, at this stage, assumed to match (as the page is created programmatically when the group is created).

    /**
 * When a new group is created, assign read capabilities to their page
 * (relies on doublee_create_group_page to create the page)
 *
 * @param $group_id
 */
function doublee_assign_group_page_access($group_id) {

	// Get the group name and slug for later use
	$group_name = doublee_get_group_name($group_id);
	$group_slug = doublee_build_title_slug($group_name);

	// Get the page ID from the group slug (assumes they match)
	$page_id = doublee_get_group_page_id($group_slug);

	// Set up array for the post meta. We can assume no-one is currently set to read this page because it'd brand new
	$can_read = array();
	array_push($can_read, $group_id);

	// Update the post meta with the new read capability
	update_post_meta($page_id, 'groups-read', $can_read);
}
add_action('groups_created_group', 'doublee_assign_group_page_access', 10);

    …but it doesn’t work. Is update_post_meta the correct way to assign the read capability? Is there something that the plugin provides that could be used to do this?

    Hi,

    Yes, the group restriction is a post meta value.
    Although I haven’t run your code, the meta_value for meta_key groups-read should be the group id. If you are calculating the group_id and the page_id correctly, then it should work.

    Hope it helps.

    Thank you for the quick reply George, and apologies that it has taken me so long to reply as I only just came back to this.

    I had been trying to assign an array of IDs instead of one, which isn’t really necessary as I’m doing one group per page, I just wrongly thought that was the correct format.

    I also combined this with the creation of the page, as I learnt that wp_insert_post returns the page ID if assigned to a variable, so the two functions (page creation and group permission assignment) do not need to be separate.

    (I also believe that way is better as combining both steps into the one function removes the risk of the page ID being incorrect – as it’s been created immediately before the permission assignment with no opportunity for another function or user action to interfere.)

    Here is the updated, working code – in terms of the specific problem this post was about, I just removed the step to create an array containing $group_id and popped that variable straight into the update_post_meta call.

    
/**
 * When a new group is created, create their page
 * and assign read capabilities
 * @param $group_id
 */
function doublee_create_group_page($group_id) {

	// Get the group name
	$group_name = doublee_get_group_name($group_id);

	// Set up the page
	$post_data = array(
		'post_title'    => $group_name,
		'post_type'     => 'page',
		'post_status'   => 'publish',
		'post_name'     => doublee_build_title_slug($group_name),
	);

	// Create the page and return its ID as $page_id
	$page_id = wp_insert_post($post_data, true);

	// Update the post meta with the read capability for the group
	update_post_meta($page_id, 'groups-read', $group_id);

}
add_action('groups_created_group', 'doublee_create_group_page', 5);

    I’m glad it’s working and thank you for sharing your code in case someone else finds it useful.

    Cheers,
    George
