[英]Create a coupon programmatically since WooCommerce 3+
I add coupons at woocommerce with this code programmatically.我以编程方式使用此代码在 woocommerce 添加优惠券。
if(empty($coupon_post)){
$coupon = array(
'post_title' => $coupon_code,
'post_content' => '',
'post_status' => 'publish',
'post_author' => 1,
'post_type' => 'shop_coupon'
);
$new_coupon_id = wp_insert_post( $coupon );
// Add meta
update_post_meta( $new_coupon_id, 'discount_type', $discount_type );
update_post_meta( $new_coupon_id, 'coupon_amount', $amount );
update_post_meta( $new_coupon_id, 'individual_use', 'yes' );
update_post_meta( $new_coupon_id, 'product_ids', '' );
update_post_meta( $new_coupon_id, 'exclude_product_ids', '' );
update_post_meta( $new_coupon_id, 'usage_limit', '' );
update_post_meta( $new_coupon_id, 'expiry_date', '' );
update_post_meta( $new_coupon_id, 'apply_before_tax', 'yes' );
update_post_meta( $new_coupon_id, 'free_shipping', 'no' );
update_post_meta( $new_coupon_id, 'exclude_sale_items', 'no' );
update_post_meta( $new_coupon_id, 'free_shipping', 'no' );
update_post_meta( $new_coupon_id, 'product_categories', '' );
update_post_meta( $new_coupon_id, 'exclude_product_categories', '' );
update_post_meta( $new_coupon_id, 'minimum_amount', '' );
update_post_meta( $new_coupon_id, 'customer_email', '' );
}
But it says always the usage_limit = 1.但它总是说usage_limit = 1。
I add additional this code to update:我添加了额外的代码来更新:
add_action( 'save_post_shop_coupon', 'my_child_after_coupon_save', 10, 3 );
function my_child_after_coupon_save( $post_id, $post, $update ) {
update_post_meta( $post_id, 'usage_limit', '');
}
But it doesn't work first.But if I open the coupon in the backend and update without any changes.但它首先不起作用。但是如果我在后端打开优惠券并在没有任何更改的情况下更新。 The usage limit is set to unlimited.使用限制设置为无限制。
How can trigger this, that I needn't to open all coupons.怎么会触发这个,我不需要打开所有的优惠券。
Since WooCommerce 3, your code is a bit outdated as for example apply_before_tax
is not used anymore.由于 WooCommerce 3,您的代码有点过时,例如apply_before_tax
不再使用。 You should better use all available WC_Coupon
setter methods , for coupon creation.您最好使用所有可用WC_Coupon
设置方法来创建优惠券。
In the code below I just use the necessary setter methods (related to your code) :在下面的代码中,我只使用了必要的 setter 方法(与您的代码相关) :
// Get an empty instance of the WC_Coupon Object
$coupon = new WC_Coupon();
// Set the necessary coupon data (since WC 3+)
$coupon->set_code( $coupon_code ); // (string)
// $coupon->set_description( $description ); // (string)
$coupon->set_discount_type( $discount_type ); // (string)
$coupon->set_amount( $coupon_amount ); // (float)
// $coupon->set_date_expires( $date_expires ); // (string|integer|null)
// $coupon->set_date_created( $date_created ); // (string|integer|null)
// $coupon->set_date_modified( $date_created ); // (string|integer|null)
// $coupon->set_usage_count( $usage_count ); // (integer)
$coupon->set_individual_use( true ); // (boolean)
// $coupon->set_product_ids( $product_ids ); // (array)
// $coupon->set_excluded_product_ids( $excl_product_ids ); // (array)
$coupon->set_usage_limit( 0 ); // (integer)
// $coupon->set_usage_limit_per_user( $usage_limit_per_user ); // (integer)
// $coupon->set_limit_usage_to_x_items( $limit_usage_to_x_items ); // (integer|null)
// $coupon->set_free_shipping( $free_shipping ); // (boolean) | default: false
// $coupon->set_product_categories( $product_categories ); // (array)
// $coupon->set_excluded_product_categories( $excl_product_categories ); // (array)
// $coupon->set_exclude_sale_items( $excl_sale_items ); // (boolean)
// $coupon->set_minimum_amount( $minimum_amount ); // (float)
// $coupon->set_maximum_amount( $maximum_amount ); // (float)
// $coupon->set_email_restrictions( $email_restrictions ); // (array)
// $coupon->set_used_by( $used_by ); // (array)
// $coupon->set_virtual( $is_virtual ); // (array)
// Create, publish and save coupon (data)
$coupon->save();
Now to update coupons you can use the following hooked function with any setter method like:现在要更新优惠券,您可以使用以下钩子 function 和任何设置方法,例如:
add_action( 'woocommerce_coupon_options_save', 'action_coupon_options_save', 10, 2 );
function action_coupon_options_save( $post_id, $coupon ) {
$coupon->set_usage_limit( 0 );
$coupon->save();
}
Code goes in functions.php file of the active child theme (or active theme).代码进入活动子主题(或活动主题)的functions.php文件。
