As a WordPress plugin developer, you may be asked to add WooCommerce integration to your plugin. In this article, we’ll cover what you need to know to get started.
What is WooCommerce?
WooCommerce is an eCommerce plugin for WordPress. It allows you to sell products and services online.
Why Would I Need to Integrate WooCommerce?
If your plugin provides features that are relevant to eCommerce, then you may need to integrate with WooCommerce. For example, if your plugin provides a shipping calculator, then you’ll need to integrate with WooCommerce to get the customer’s shipping address.
How Do I Integrate WooCommerce?
The first thing you’ll need to do is install the WooCommerce plugin. You can do this from the WordPress plugin repository.
Once WooCommerce is installed, you’ll need to add the following code to your plugin:
This code will check if WooCommerce is activated, and if it is, your code will run.
Wrapping Up
Adding WooCommerce integration to your plugin is a straight-forward process. First, you’ll need to install WooCommerce. Then, you can add code to your plugin to take advantage of WooCommerce’s features.
Step 4: Add the following to your plugin’s main file
Now that you have your plugin set up and your files in place, it’s time to start adding some code.
In your plugin’s main file, you’ll need to include the following:
The WooCommerce plugin header.
This tells WooCommerce that your plugin exists and provides some basic information about it, such as the plugin name and author.
You can find a detailed guide to the plugin header here.
A call to the WC()->integrations->add_integration() function.
This tells WooCommerce to load your integration class so it can be used by the plugin.
Your integration class.
This is the class that contains all the code for your integration. We’ll be covering this in more detail later on.
Step 5: Write your integration class
Now it’s time to start writing some code. In this section, we’ll cover the basics of your integration class.
Your integration class will need to extend the WC_Integration class. This class provides the basic structure for all WooCommerce integrations.
Your class will also need to contain a constructor. This is where you’ll define all the settings fields for your integration.
For each setting field, you’ll need to call the add_setting() method. This method takes three arguments:
The setting ID. This should be unique to your plugin and should be prefixed with your plugin’s name to avoid collisions with other plugins’ setting IDs.
The setting’s type. This can be either ‘text’ or ‘checkbox’.
The setting’s label. This is the label that will be displayed next to the setting field on the WooCommerce settings page.
You can find a full list of the arguments that can be passed to the add_setting() method in the WooCommerce documentation.
Once you’ve added all your setting fields, you’ll need to call the add_form_fields() method. This method takes two arguments:
An array of form fields. This is where you’ll define all the fields that will be displayed on the WooCommerce settings page.
A callback function. This function will be called when the form is submitted. It should take two arguments: the first argument will be the posted data, and the second argument will be the current settings.
You can find a full list of the arguments that can be passed to the add_form_fields() method in the WooCommerce documentation.
Finally, you’ll need to call the init_form_fields() method. This method takes no arguments and is used to populate the form fields array that is passed to the add_form_fields() method.
Once you’ve added all the required methods to your class, it should look something like this:
class WC_MyPlugin_Integration extends WC_Integration {
public function __construct() {
$this->id = ‘myplugin’;
$this->method_title = __( ‘My Plugin’, ‘myplugin’ );
$this->init_form_fields();
}
public function init_form_fields() {
$this->form_fields = array(
‘myplugin_setting_1’ => array(
‘type’ => ‘text’,
‘label’ => __( ‘My Setting 1’, ‘myplugin’ )
),
‘myplugin_setting_2’ => array(
‘type’ => ‘checkbox’,
‘label’ => __( ‘My Setting 2’, ‘myplugin’ )
)
);
}
}
WC()->integrations->add_integration( ‘WC_MyPlugin_Integration’ );
Step 6: Register your integration
Now that you have your integration class set up, you need to register it with WooCommerce.
This is done by calling the WC()->integrations->add_integration() function. This function takes one argument: the name of your integration class.
You’ll need to add this code to your plugin’s main file, after your integration class.
Step 7: Test your integration
Now that you’ve registered your integration, it should appear on the WooCommerce settings page.
Test your integration by changing the settings and saving the changes. Then, check that the changes have been applied correctly.
If you need to, you can access the integration settings from your plugin code using the WC()->integration->get_options() method. This method takes one argument: the ID of the setting you want to retrieve.
Conclusion
In this article, we’ve covered how to create a basic WooCommerce integration. We’ve also looked at how to register your integration and how to access the integration settings from your plugin code.
Now that you know the basics, you can start adding more features to your integration. For more information, see the WooCommerce documentation.
Now that you have your WooCommerce plugin set up, it’s time to integrate it with your WordPress site.
There are two ways to do this:
1. Use the WooCommerce REST API
2. Use the WooCommerce PHP SDK
Using the WooCommerce REST API is the recommended way to integrate with WooCommerce. It is a modern and flexible way to connect to WooCommerce and allows you to use the latest WooCommerce features.
To use the WooCommerce REST API, you will need to register for a WordPress.com account and then connect your site to WordPress.com. Once your site is connected, you will be able to access the WooCommerce REST API.
To use the WooCommerce PHP SDK, you will need to download the SDK and include it in your plugin. You will also need to set up a WordPress.com account and connect your site to WordPress.com. Once your site is connected, you will be able to access the WooCommerce PHP SDK.
