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!
