Restricting pertain products in the catalog based off their post code. WooCommerce Catalog Visibility Options plugin on woocommerce
I’m a beginner to php and I’m trying to edit the code in a woocommerce plugin called Catalog Visibility options. The plugin is used to restrict the visibility of certain products in the store depending on the country or state/region the user is located at. I would like to change the visibility options based off the post code of the user as opposed to country or state/region. I tried to look into the php code and found this line
array( 'name' => __( 'Location Filter Type', 'wc_catalog_restrictions' ), 'desc' => '', 'css' => 'min-width:300px;', 'id' => '_wc_restrictions_locations_type', 'type' => 'select', 'std' => 'countries', 'default' => 'countries', 'class' => 'chosen_select', 'options' => array( 'countries' => 'Countries', 'states' => 'States / Territories' )
What I would like to know is where the last line of that code is used so I could possibly add some code that can help me display products based off their post code. I know this question is very specific and someone who uses the plugin would probably be the ideal person who can help me.
