Using: mucd_default_primary_tables_to_copy

I have the same question. I want to clone my primary site. How to do this?

Hey, I just cloned primary site with this plugin. Looks good so far!

Had to dig for this. Bizarre not to explain the use of the plugin’s hooks. Here is an example. It will go in your theme’s functions.php file:

function mucd_primary_table_to_copy($primary_tables) {
    $primary_tables[] = 'frm_fields';
    $primary_tables[] = 'frm_forms';
    $primary_tables[] = 'frm_items';
    $primary_tables[] = 'frm_item_metas';
    return $primary_tables;
}

add_filter('mucd_default_primary_tables_to_copy', 'mucd_primary_table_to_copy');
