How can I see when a coupon is created in WooCommerce? - php

Question

I am writing a custom plugin and I need to automatically send information about every newly created coupon. Until now, I can only choose a specific coupon by its name(e.g. 1234):
$coupon = new WC_Coupon("1234");
But I cannot seem to find how to get a coupon right after its created, without knowing its name, or at least how to get all of the available coupons. Can someone help?

Answer 1

May be this might help. Tested and it's working. This will return all coupons since coupons are saved as post_type shop_coupon.
$args = array(
'posts_per_page' => -1,
'orderby' => 'title',
'order' => 'asc',
'post_type' => 'shop_coupon',
'post_status' => 'publish',
);
$coupons = get_posts( $args );

Answer 2

Try to get using custom post type or directly mysql query.
1) Using mysql query
// Run a query on the postmeta table to get the id of every coupon that has the email in the customer_email restrictions
$couponlist = $wpdb->get_results("SELECT
`wp_postmeta`.`post_id`
FROM `wp_postmeta`
WHERE `wp_postmeta`.`meta_key` LIKE 'customer_email'
AND `wp_postmeta`.`meta_value` LIKE '%".$email."%'");
$couponarrayfinal = array( ); //Create an array of the ids so we can use wp_query to more quickly grab the data
// Add the ids to the array in a foreach loop
foreach( $couponlist as $key => $row) {
$value = $row->post_id;
$couponarrayfinal[] = $value ;
}
2) Using get_posts method
$arg = array(
'posts_per_page' => -1,
'orderby' => 'title',
'order' => 'asc',
'post_type' => 'shop_coupon',
'post_status' => 'publish');
$coupons_list = get_posts( $arg );

Try with this you will get the all the data
// WP_Query arguments
$args = array(
'post_type' => array('shop_coupon'),
'post_status' => array('publish'),
'posts_per_page' => '-1',
'order' => 'DESC',
'orderby' => 'id',
);
// The Query
$query = new WP_Query($args);
// The Loop
if ($query->have_posts()) {
while ($query->have_posts()) {
$query->the_post();
// do something
$coupon = new WC_Coupon(get_the_ID());
$coupnCode = $coupon->code;
$coupnAmount = $coupon->amount;
$minAmount = wc_format_decimal($coupon->minimum_amount, 2);
$maximumAmount = wc_format_decimal($coupon->maximum_amount, 2);
$expire = $coupon->expiry_date;
}
} else {
// no posts found
}
// Restore original Post Data
wp_reset_postdata();
