Can you please tell me where it should be placed ?

You would put this code inside a new function in your functions.php file. It's up to you when you'd need call that function. E.g., I am using it so that when a certain page loads, the function is called to create the coupon and then email the code to the user. If you wanted to show the new code on screen, you could quite easily have the function return 'UNIQUECODE'.

NB - Normally, you'd create a coupon by logging in to yoursite.com/wp-admin and going WooCommerce > Coupons > Add Coupon.

I created a new function in functions.php and tried to call it in another page but it never showed the coupon and even coupon wasn't created as i see nothing in WooCommerce > Coupons

Am i doing something wrong or the code is not working anymore?

I have done this with some changes. Here's my code on functions.php (then I created a private page where i call this function and it generates the coupon automatically.)

/* generate $15 off coupons */
function generate_coupons15 () {
$coupon_code = substr( "abcdefghijklmnopqrstuvwxyz123456789", mt_rand(0, 50) , 1) .substr( md5( time() ), 1); // Code
$coupon_code = substr( $coupon_code, 0,10); // create 10 letters coupon
$amount = '15'; // Amount
$discount_type = 'fixed_cart'; // Type: fixed_cart, percent, fixed_product, percent_product

$coupon = array(
    'post_title' => $coupon_code,
    'post_content' => '$15 off coupon',
    'post_excerpt' => '$15 off coupon',
    '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', '1' );
update_post_meta( $new_coupon_id, 'expiry_date', '' );
update_post_meta( $new_coupon_id, 'apply_before_tax', 'no' );
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', '' );       

return $coupon_code;

}

Would it be possible to use this code to automatically create a coupon code at checkout using the customer's "username" as the coupon code? I want it to be easy to remember for the customers so they can share the coupon codes......I have an affiliate program based on their coupon codes.

Ex. I create username "Mac" at checkout(username required on my site) and instantly coupon code "Mac" would be generated. This coupon could be used unlimited times and would be for 20% Off. If user name "Tim" is used, "Tim" would become a 20% Off coupon code etc.

Any help would be greatly appreciated, thanks in advance!

Mac

for some reason i am getting that wp_insert_post is undefined after i added some code to this function,
please take a look at my code if you may let me know what i am doing wrong, just to let you know, this function is in a separate like which is included in functions.php and i am posting to that file using jQuery.post() from index.php
this is code:
`<?php

$subEmail = isset($_POST['subEmail']) ? $_POST['subEmail'] : null;

if($subEmail){
    justDoIt($subEmail);
}

function justDoIt($subEmail){

    define( 'SHORTINIT', true );
    // local
    require_once( $_SERVER['DOCUMENT_ROOT'] . '/wordpress/wp-load.php' );
    // live
    // require_once( $_SERVER['DOCUMENT_ROOT'] . '/wp-load.php' );
    global $wpdb;

    //Check if $subEmail is in DB
    $emailsQuery = 'SELECT meta_value FROM wp_postmeta WHERE meta_key = "_field_newsletteremail"';

    $dbEmails = $wpdb->get_results( $emailsQuery );

    foreach($dbEmails as $emailObj){
        if($subEmail === $emailObj->meta_value){
            echo "exists";
            die();
        }
    }
    //else create a coupon for him
    $couponCodeValue = $subEmail.time();
    $couponCodeValue = str_replace(' ', '', $couponCodeValue);
    $couponCodeValue = md5($couponCodeValue);

    //Get Existing Coupons we created
    $dbCoupons = $wpdb->get_results( 'SELECT post_title FROM wp_posts WHERE post_type = "shop_coupon" AND post_status = "publish"' );
    $x = 0;
    $y = 6;
    $couponCodeSixValue = substr($couponCodeValue, $x , $y);

    for($y; $y < strlen($couponCodeValue); $y++){
        //if code found generate new one, else just us the current
        if($dbCoupons[$i]->post_title === $couponCodeSixValue){
            $couponCodeSixValue = substr($couponCodeValue, ($x+1) , ($y+1));
        }
        $x++;
    }

    imagineme_create_coupon($couponCodeSixValue);

}


function imagineme_create_coupon( $couponCodeSixValue ){
    
    $coupon_code = $couponCodeSixValue; // Code
    $amount = '10'; // Amount
    $discount_type = 'fixed_cart'; // Type: fixed_cart, percent, fixed_product, percent_product
                        
    $coupon = array(
        'post_title' => ''.$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 );

This is my code and I am trying to add a coupon for my online store but it's not working

add_action( 'woocommerce_before_cart', 'sh_coupons_matched' );
function sh_coupons_matched() {
global $woocommerce;
$sh_coupon = 'OnlineShop';
if ( $woocommerce->cart->has_discount( $sh_coupon ) ) return;
foreach ( $woocommerce->cart->cart_contents as $key => $values ) {
$autocoupon = array( 65 );
if( in_array( $values['product_id'], $autocoupon ) ) {
$woocommerce->cart->add_discount( $cw_coupon );
wc_print_notices();
}
}
}

I have followed this WooCommerce coupon code tutorial to implement the whole process

@mikejolley, is this code still correct for WC4?

@dcx15 yikes it's 8 years old but it should work. However, I'd suggest looking into using the WC_Coupon class instead. https://docs.woocommerce.com/wc-apidocs/class-WC_Coupon.html

Thanks for confirming Mike!

For anyone else that stumbled on this gist via Google, I found this answer on SO useful https://stackoverflow.com/a/61874195. All of the other blog posts and SO answers seem to be very outdated in Google results.

How can we add something like add X quantity of any product and get Y % off?

@Stevemoretz

Better using the wc_coupon instance with its save method now.

@mikejolley Does this work in 2023? I'm just starting a new store with my own designs and I can't really afford to pay for those 50$ a month plugins (not before I will actually start making some money on this :D)
Thank you for all the effort you put in this so far!
