README

Meta Box Generator is a WordPress plugin for allowing database migrations to be done with code.

Requirements

• Composer version 2+ https://getcomposer.org/

Installation

Installing this plugin assumes you are managing plugins for a WordPress site with composer or wp-packagist. It is currently not part of the WordPress plugin repository so it can't be installed with wp-packagist.

Add the following configuration to your composer.json. If you are managing plugins with wp-packagist, this configuration may already be present.

    "extra": {
        "installer-paths": {
            "plugins/{$name}/": ["type:wordpress-plugin"]
        }
    }

Install with composer

composer require grofftech\wp-migrator

Usage

Metabox Configuration

Hook into the filter mbg_add_metabox_configuration_files and include file(s) that have an array returned like the sample below. Make sure the filter is configured in your plugin during its initialization, so that it can be properly registered.

add_filter( 'mbg_add_metabox_configuration_files', 'add_files');
function add_files( $files ) {
    $files[] = // Directory path to your file

    return $files;
}

For your returned array, use the sample below. Replace the metabox.sample key in the array to the name of the meta box you are configuring (e.g. metabox.article). Update the add_meta_box configuration to be specific for your meta box. See https://developer.wordpress.org/reference/functions/add_meta_box/. Update the view key to a directory path of your view file for the meta box.

return array(
    'metabox.sample' => array(
        'add_meta_box' => array(
            'title' => __('Sample Meta Box', 'your_text_domain'), // The title of the meta box
            'screen' => 'post', // The post type
            'context' => 'advanced', // Where it should be displayed for the screen
            'priority' => 'default', // default, high, low
            'callback_args' => null, // Additional params for the callback
            'include_custom_fields' => false
        ),
        'custom_fields' => array()
        ),
        'view' => // Directory path to your view file
    )
);

If you need to include custom fields in your meta box, set the include_custom_fields key to true and configure an array of options for your custom view(s) using the sample below.

'custom_fields' => array(
    'sample_custom_field' => array( // replace sample_custom_field your your custom field name
        'is_single' => true, // ?
        'default' => '', // ?
        'delete_state' => '', // ?
        'sanitize' => 'sanitize_text_field' // A WordPress sanitize function for your custom field
    ),
    // Another custom field configuration would go here if multiple, configured just like above
),
