Display Conditions & Metabox

[aricmb]

I have a custom post type setup using metabox with a custom field using a simple checkbox. The goal is that each department in an organization can check and uncheck sections that they want displayed on their department’s page.

I’m attempting to use the conditions builder api along with custom written php to get the right output.

I’m having the php output the custom post type ID based on the page’s taxonomy to look up the display_staff custom field for that post type. Then loop that into the Bricks condition builder.

Am I making this more complicated than it needs to be? Here’s the code I’ve been working with:

<?php

// Conditions Builder API

// Custom condition group
add_filter("bricks/conditions/groups", "add_my_custom_condition_group");
function add_my_custom_condition_group($groups)
{
    $groups[] = [
        "name" => "custom_department_conditions",
        "label" => esc_html__("Department Conditions", "text-domain"),
    ];
    return $groups;
}

// Custom condition options to the group
add_filter("bricks/conditions/options", "add_my_custom_conditions_to_group");
function add_my_custom_conditions_to_group($options)
{
    $options[] = [
        "key" => "department_display_staff",
        "label" => esc_html__("Display Staff", "text-domain"),
        "group" => "custom_department_conditions",
        "compare" => [
            "type" => "select",
            "options" => [
                "==" => esc_html__("is", "text-domain"),
                "!=" => esc_html__("is not", "text-domain"),
            ],
        ],
        "value" => [
            "type" => "text",
        ],
    ];
    return $options;
}

// Function to store and retrieve department data
function get_department_data()
{
    // Check if data is already cached
    $cached = get_transient("department_data");
    if ($cached) {
        return $cached;
    }

    // Initialize an empty array to store the data
    $department_data = [];
