Creating manual metaboxes is a difficult and time consuming task. And what about when you need to create these metaboxes (custom fields) automatically, when we activate the theme or plugin, this will be useful when developing custom themes.
Redux Framework plugin which located in the WordPress repository, so there will be no problems with its connection.
1. Let’s connect a script TGM Plugin Activation
2. Add code below in yours function.php file
require_once get_template_directory() . '/inc/class-tgm-plugin-activation.php';
add_action( 'tgmpa_register', 'clean_register_required_plugins' );
function clean_register_required_plugins() {
/*
* Array of plugin arrays. Required keys are name and slug.
* If the source is NOT from the .org repo, then source is also required.
*/
$plugins = array(
// This is an example of how to include a plugin from the WordPress Plugin Repository.
array(
'name' => 'Gutenberg Template and Pattern Library & Redux Framework',
'slug' => 'redux-framework',
'required' => true,
),
);
$config = array(
'id' => 'clean', // Unique ID for hashing notices for multiple instances of TGMPA.
'default_path' => '', // Default absolute path to bundled plugins.
'menu' => 'tgmpa-install-plugins', // Menu slug.
'parent_slug' => 'themes.php', // Parent menu slug.
'capability' => 'edit_theme_options', // Capability needed to view plugin install page, should be a capability associated with the parent menu used.
'has_notices' => true, // Show admin notices or not.
'dismissable' => true, // If false, a user cannot dismiss the nag message.
'dismiss_msg' => '', // If 'dismissable' is false, this message will be output at top of nag.
'is_automatic' => false, // Automatically activate plugins after installation or not.
'message' => '', // Message to output right before the plugins table.
);
tgmpa( $plugins, $config );
}
3. Now you can create file with options. Let’s call it redux-init.php. Place this file in a folder /wp-content/themes/yourthemename/inc/.
The code below is an example of a ready-made options panel on Redux. Edit this code to suit your needs.
How to create yours Redux options is explained in this article – How to create yours WordPress theme options on Redux
