Reply To: Random code field for coupons system

Hello @shonlevi ,

If I understand correctly, perhaps you could have 3 fields…

Field 1: Text box for value such as: EXAMPLE

Field 2: Number… for how many coupons to generate

Field 3: Repeater field for the coupon codes.

Then, you could enter values in the first 2 boxes, and then use the update_field function to generate the codes..

Here’s partial example code for updating a repeater:

<?php
$prefix = get_field('prefix', $post_id);
$number_of_coupons = get_field('number_of_coupons', $post_id);
$repeater_field_key = "field_12345678";
$i = 1;
while ($i <= $number_of_coupons) {
 //// use PHP 'rand' or 'shuffle' to generate some random numbers
 //// create a 'value' by joining the 'prefix' with a 'random number'
 //// put your logic in here to add values to the array
  $i++;
}

///// here is how to add one value to the array
$value = array(
  array(
    "coupon_code" => "Foo"
  )
);
update_field( $field_key, $value, $post_id );
?>

Hope that gets you on the right path… clearly there is some work left to do and some testing, but that should get you going!
