wpgenie's WooCommerce plugins

WooCommerce REST API is useful for creating headless shops and automating processes . Here we will show couple of examples where you can see how our plugins can be managed via Woo REST api like how to retrieve product data and how to create new auction product using WooCommerce REST API v3.

First you will need to go to WooCommerce Settings -> Advanced and enable REST API then create client key and secret, then assign permissions you need for your use case.

Once this is completed go to https://github.com/Automattic/wp-rest-php-lib and download their PHP lib. Extract so you have folder structrue something like https://www.yourwebsite.com\api\WooCommerce and in \api\ create test_api.php file. Their lib is intented to be used with Composer and we advise that but in the example we will not use Composer in order to have as less prerequisites as possible.

Code example for WooCommerce REST API – listing auctions and creating new auction product

Since WooCommerce REST API can retrieve custom product types we will use type parameter to retrieve all auction products available in our Woo product list. Copy paste into your test_api.php file following code:

<?php

include_once(__DIR__ . '/WooCommerce/HttpClient/BasicAuth.php');
include_once(__DIR__ . '/WooCommerce/HttpClient/HttpClient.php');
include_once(__DIR__ . '/WooCommerce/HttpClient/HttpClientException.php');
include_once(__DIR__ . '/WooCommerce/HttpClient/OAuth.php');
include_once(__DIR__ . '/WooCommerce/HttpClient/Options.php');
include_once(__DIR__ . '/WooCommerce/HttpClient/Request.php');
include_once(__DIR__ . '/WooCommerce/HttpClient/Response.php');
include_once(__DIR__ . '/WooCommerce/Client.php');

use Automattic\WooCommerce\Client;

$woocommerce = new Client(
	'https://www.yourwebsite.com',
	'your_client_key',
	'your_client_secret',
	[
	   'wp_api'  => true,
	   'version' => 'wc/v3',           
	]
);
$data = [
    'type' => 'auction' // get all auction products
];
print_r( $woocommerce->get( 'products', $data) );

Examples how to get and create auction products (for WooCommerce Simple Auctions) using WooCommerce API:

$data = [
    'name' => 'New Auction',
    'type' => 'auction',
    'status' => 'draft', // status can be: draft, published, pending

    'meta_data' => array(
        [ 'key' => '_auction_start_price', 'value' => '7.99' ],             // starting bid
        [ 'key' => '_auction_bid_increment', 'value' => '1.5' ],            // min bid increment
        [ 'key' => '_regular_price', 'value' => '2900' ],                   // buy now price
        [ 'key' => '_auction_reserved_price', 'value' => '2000.0' ],       // reserve price
        [ 'key' => '_auction_dates_from', 'value' => '2022-02-11 00:00' ],  // start date
        [ 'key' => '_auction_dates_to', 'value' => '2022-02-27 00:00' ],    // end date
        [ 'key' => '_auction_proxy', 'value' => 'no' ], // proxy auction, yes | no   
        [ 'key' => '_auction_sealed', 'value' => 'no' ], // sealed auction, yes | no        
    ),

    'description' => 'This is sample auction added via WooCommerce API',
    'short_description' => 'Sample api auction.',    
];


print_r( $woocommerce->post( 'products', $data ) );

print_r( $woocommerce->post( 'products', $data ) );

How can you limit number of produtcs retrieved? You can use per_page attribute in $data like below (search, offset, order, order by etc options are available useful for paging and filtering) – all available parameters are listed here https://woocommerce.github.io/woocommerce-rest-api-docs/#list-all-products:

$data = [
    'per_page' => 1,    // api will return only 1 auction product
    'type' => 'auction'
];


print_r( $woocommerce->get( 'products', $data) );

Complete REST API documentation can be found on https://woocommerce.github.io/woocommerce-rest-api-docs/. If you have additional questions on how WooCommerce REST API works with WooCommerce Simple Auctions, WooCommerce Lottery and WooCommerce Group Buy please open ticket here or contact us.

One of the common inqury in our support tickets, unrelated to plugin functionality, was how to change number of products displayed on WooCommerce product archive page.

Most themes come with settings page where you can change number of producs displayed, in fact you can change number of rows and columns per page but there are also themes without that option.

So to do that you need to add code to your child theme’s functions.php file. Avoid adding custom code directly to your parent theme’s functions.php file as this will be wiped entirely when you update the theme.

This solution requires you to have your shop page display (WooCommerce > Product catalog set to “Show products”). Code snippet is below (snippet is from woocommerce.com):

/**
 * Change number of products that are displayed per page (shop page)
 */
add_filter( 'loop_shop_per_page', 'new_loop_shop_per_page', 20 );

function new_loop_shop_per_page( $cols ) {
  // $cols contains the current number of products per page based on the value stored on Options –> Reading
  // Return the number of products you wanna show per page.
  $cols = 9;
  return $cols;
}
