Add filters to default country,state, and currency on WooCommerce

WooCommerce is awesome plugin, you can use it to make e-commerce on your website. But sometime we need add some country, state, or currency into this plugin. We can edit manually with edit some file in this plugin but if we updated the plugin the file will be replaced, and all customization what we have done is gone.

Now, i will be show you how to add currency and country with filter in this plugin. Remember that everything is filtered. Woo is using the woocommerce_currency_symbol filter for filtered the currency and woocommerce_countries filter for filtered country in woocommerce.php. To add currencies to that list, you’d use:

function add_my_currency_symbol( $currency_symbol, $currency ) {     if($currency == "IDR") {         $currency_symbol = 'Rp';     }     return $currency_symbol; } add_filter( 'woocommerce_currency_symbol', 'add_my_currency_symbol', 10, 2 ); 

Whenever Woo calls their function, they pass the currency symbol through a filter before returning it. You’re just hooking on to that filter, checking to see if the currency matches your custom value, and returning a custom symbol if so. I used Rupiah here as an example, but substitute whatever it is you need.

To add your currency to the settings page, you’ll hook into the woocommerce_currencies filter:

function add_my_currency( $currencies ) {     
$currencies["IDR"] = 'Rupiah';     
return $currencies; 
} 
add_filter( 'woocommerce_currencies', 'add_my_currency', 10, 1 ); 

To add country  to that list, you’d use:

function add_my_country( $country ) {     
$country["NC"] = 'New Country'; 
return $country; 
} 
add_filter( 'woocommerce_countries', 'add_my_country', 10, 1 );

To add states  to that list, you’d use:

function add_my_states( $states ) {     
$states["ID"] = array( 'BA' => __('Bali', 'woocommerce') ,'JB' => __('Jawa Barat', 'woocommerce')); 
return $states; 
} 
add_filter( 'woocommerce_states', 'add_my_states', 10, 1 );

Woo is adding an array of currencies to their options panel. All this does is look at the array, add your custom currency, then return it so the function can operate as normal.

Where to put this code

To use these filters, you’ll have to write a that’s code in your function.php at your theme file. When you update WooCommerce, so long as they don’t change their filter names, you shouldn’t lose any customizations.

I hope that can help you to make your website more awesome, keep on fire yeah 🙂
