Remove Catalog Visibility Hidden Products In WooCommerce From Search & WP REST API Results

Woo doesn’t filter out products with hidden catalog visibility outside of main shop loop. This is important to remember when using the REST API for front end display or general search results. This code snippet will keep them from showing outside of the admin.

Turn Off Localization Temporarily in WooCommerce

I’m working on a site that’s in Japanese.  It’s a huge WooCommerce shop and they have a lot of custom meta fields we built for the English version of things.  Customers have their first and last name in my account and also fields we made for English First Name and English Last Name.

On the Addresses endpoint of WooCommerce’s “My Account” section we wanted to display the names/addresses in both Japanese and English.  This seemed easy except the Japanese state name that’s generated by Woo was being translated in the ‘woocommerce’ text domain.  The work-around was to unload the text domain, reload the countries/states instance with the data, get our state then reload the text domain.  This snippet did the trick:

WooCommerce: Add Fee To Order During Checkout If Cash On Delivery Or Any Other Reason/Gateway

Recently I was tasked with adding a field to the cash on delivery gateway in WooCommerce.  They wanted a field they could put in a dollar amount that would be tacked on as a fee to orders using that gateway.  Seemed simple enough with some googling but took a bit longer to tweak and get functioning correctly.

Add Field to Cash On Delivery Gateway

Adding fields in WooCommerce to its forms is pretty straight forward.  You hook into the WC Settings API and adjust them using this hook:

add_filter( 'woocommerce_settings_api_form_fields_<id>', function( $form_fields ) { return $form_fields; } );

Replace <id> with the id of the form.  In this case it’s “cod” for the Cash on Delivery form. In your hooked function you can manipulate the form fields array as needed.  For my case I just needed to add a field at the end for a fee so I do this:

Add Fee To The Order

Now that we have a fee set we need to hook into the checkout process.  For this I use the action “woocommerce_checkout_create_order” to manipulate the order right before it’s saved.  In WooCommerce 3.0 and over you no longer use the add_fee() function but instead create a line item fee object and add that to the order.  Here’s how I did what I needed:


Notice the add_item( $item ) call to place it in the order.  If that’s all you do then you will see the fee on the order but the order total won’t include it.  You need to make sure you run the order’s calculate_totals() function after adding the item.

Creating a Custom or Extended Gravity Forms Field with Multiple Inputs

I’m building a site for a Japanese company.  They need a Gravity Forms address field with a different order.  I spent a BOATLOAD of time trying to get this working and I finally did.  Here’s some details.

Extending Address Field

I started by extending the address field.  Simple enough.  Made some tweaks to the get_field_input() function to reorganize.  Made sure all other functions that used the .1, .2, etc. id’s for the inputs inside the field were updated in my field class.

After some trial and error with those I got the form field to be in the admin so I could add it to a form.  Awesome! Went to the front and there’s my new beautiful field.  But no matter how hard I tried it would not save any of the data.

I searched and searched through all the hooks I could find related to this.  I almost gave up but then I found a comment that said something about default inputs were loaded in js.php file.


In the root directory of Gravity Forms is a file named js.php.  This file runs a switch case on different field types and populates some data.  If you look towards the bottom around line 838 at the writing of this post you will see:

<?php do_action( 'gform_editor_js_set_default_values' ); ?>

Right there you need to hook in your own default settings with field.inputs defined.  That’s about it! I just copied the info they had for the address field, tweaked it to match my class’s data and voila.
