Im editing a plugin for woocommerce that normally generates random coupon codes. but i needed it to generate them in order (000001, 000002, 000003, etc etc or 1, 2, 3, etc etc). but i cant make it work. ive messed around with if statements and everything. i’ll post what i have now and the original code.

My code now:

function wccg_get_random_coupon() {

// Generate unique coupon code
$random_coupon = '';
$length        = 6;
$charset       = '0123456789';
$count         = strlen( $charset );

while ( $length-- ) {
    for ($a = 0; $a <= $count; $a++) {
    
$random_coupon = implode( '-', str_split( strtoupper( $random_coupon ), 6 ) );

// Ensure coupon code is correctly formatted with WC Core filter
$coupon_code = apply_filters( 'woocommerce_coupon_code', $random_coupon );

// Additional filter that only executes for this plugin, not for other WC Core coupons
$random_code = apply_filters( 'woocommerce_coupon_generator_random_coupon_code', $coupon_code );

return $random_code;
} }

}

Original code:

        function wccg_get_random_coupon() {

// Generate unique coupon code

        $random_coupon = '';
        $length        = 12;
        $charset       = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
        $count         = strlen( $charset );

        while ( $length-- ) {
                $random_coupon .= $charset[ mt_rand( 0, $count-1 ) ];
        }

        $random_coupon = implode( '-', str_split( strtoupper( $random_coupon ), 4 ) );

    // Ensure coupon code is correctly formatted with WC Core filter
        $coupon_code = apply_filters( 'woocommerce_coupon_code', $random_coupon );

   // Additional filter that only executes for this plugin, not for other WC Core coupons
    $random_code = apply_filters( 'woocommerce_coupon_generator_random_coupon_code', $coupon_code );

    return $random_code;

}
