Adding a WooCommerce product programmatically.

add-woocommerce-product.php

<?php
$args = array(	   
	'post_author' => 1, 
	'post_content' => '',
	'post_status' => "draft", // (Draft | Pending | Publish)
	'post_title' => '',
	'post_parent' => '',
	'post_type' => "product"
); 

// Create a simple WooCommerce product
$post_id = wp_insert_post( $args );

// Setting the product type
wp_set_object_terms( $post_id, 'simple', 'product_type' );

// Setting the product price
update_post_meta( $post_id, '_price', 0 );
update_post_meta( $post_id, '_regular_price', 0 );

@andrewreal sorry, last one - can you create product categories along with this process?

@andrewreal that's awesome, looks similar to Laravel's eloquent handling of models, how would you check for an SKU already existing prior to creation / update if an SKU already exists?

You should be able to use the WooCommerce function wc_get_product_id_by_sku( $sku ) - https://woocommerce.github.io/code-reference/namespaces/default.html#function_wc_get_product_id_by_sku - to check for a product ID.

I'm not sure there is a WooCommerce function for that, unfortunately the docs at https://woocommerce.github.io/code-reference/ aren't great for discovery but you try trawling through.

You should be able to add a category with thee built in WordPress functions as shown here though https://wordpress.org/support/topic/create-woocommerce-category-in-php/

@andrewreal Getting => Trying to get property 'feeds' of non-object in path/to/wp-includes/post.php.
In fact, this is b/c of

global $wpdb, $wp_rewrite;
	$original_slug = $slug;

	$feeds = $wp_rewrite->feeds;
	if ( ! is_array( $feeds ) ) {
		$feeds = array();
	}

Feeds is using in wp_insert_post. can you please check this out? I am getting this same error in every case.
