Auto Coupon Generate for Gravity Forms for WordPress Plugin Directory

Auto Coupon Generate for Gravity Forms lets you automatically create a unique discount coupon code every time a visitor submits a Gravity Form. The generated code is saved directly as a Gravity Forms coupon and can optionally be emailed to the user straight away – no manual work required.

A common use case is a two-step flow: a user fills out a registration or survey form, receives a unique coupon code by email, and then uses it on a subsequent order form to claim their discount.

Key Features

Automatically generates a unique, random coupon code on every form submission.

Coupon codes are saved directly to the Gravity Forms Coupons Add-On – no extra steps needed.

Configurable code length, character set, and optional prefix so codes match your brand.

Supports both flat (fixed amount) and percentage discount types.

Set a minimum order value that must be met before the coupon applies.

Control how many times each coupon can be used in total.

Optional start date and expiration date for time-limited promotions.

Built-in email notification – send the generated coupon code to the user’s email address automatically after submission. The email subject and body are fully customisable, and you can use the {coupon_code} placeholder anywhere in the message body.

Coupon Log page in the WordPress admin showing a full history of every coupon generated, including the code, the form it came from, and the date it was created.

Shipping is excluded from discount calculations by default – the discount applies to the order subtotal only.

Secure: uses random_int() for cryptographically safe code generation, proper nonce verification, and capability checks on all admin pages.

Requirements

WordPress 5.2 or higher

PHP 7.0 or higher

Gravity Forms (any recent version)

Gravity Forms Coupons Add-On (must be installed and active)

The plugin will check for these dependencies on activation and will not activate if either Gravity Forms or the Coupons Add-On is missing.

Configuration After activating the plugin, go to Generate Coupon Setting in the WordPress admin menu. The settings page is divided into three sections.

Coupon Generate Form Settings These settings control how coupon codes are generated and what discount they carry.

Form ID – The ID of the Gravity Form that will trigger coupon generation on submission. To find your form ID, go to Forms in your WordPress admin; the ID is shown in the form list.

Coupon Field ID – The ID of the field inside that form where the generated coupon code will be pre-populated (using the gform_field_value_uuid filter). This is typically a hidden field.

Coupon Length – The number of random characters in the coupon code (not counting any prefix). For example, a length of 8 with the prefix SALE- would produce codes like SALE-A3BX92KQ.

Coupon Code Prefix – Optional text to prepend to every generated code (e.g. SUMMER-). Leave blank for no prefix.

Coupon Code Characters – The pool of characters used when generating the random part of the code. The default is 1234567890QWERTYUIOPASDFGHJKLZXCVBNM. You can narrow this down – for example, removing easily confused characters like 0, O, 1, and I.

Discount Type – Choose Percentage to deduct a percentage of the order total, or Flat to deduct a fixed amount.

Discount Amount – The value of the discount. If Discount Type is Percentage, enter a number between 1 and 100. If Discount Type is Flat, enter the currency amount (e.g. 10 for $10 off).

Max Usage – The maximum number of times the generated coupon can be used across all customers. Enter 1 to make it single-use.

Minimum Price – The minimum order subtotal (excluding shipping) a customer must reach before the coupon becomes valid. Leave blank for no minimum.

Start Date – The date from which the coupon becomes valid, in MM/DD/YYYY format. Leave blank to make it valid immediately.

Expiration Date – The date on which the coupon expires, in MM/DD/YYYY format. Leave blank for no expiry.

Coupon Usage Form Settings

Form ID – The ID of the Gravity Form where customers will enter and apply their coupon code (your checkout or order form). The generated coupon will be scoped to this form inside the Gravity Forms Coupons Add-On.

Email Notification Settings These settings are all optional. If you do not enable email notifications, coupons are still generated and saved – users just will not receive an automatic email.

Email Field ID – The ID of the field in the coupon-generate form that holds the user’s email address. The plugin will read the submitted value from this field and send the notification to that address.

Email Subject – The subject line of the notification email. Default: Your Coupon Code.

Email Body – The body of the notification email. Use the placeholder {coupon_code} anywhere in the text and it will be replaced with the actual generated code before sending. Default message is provided but you can customise it freely.

Enable Email – Check this box to activate automatic email sending. When unchecked, no email is sent regardless of the other email settings.

The email is sent using WordPress’s built-in wp_mail() function. Delivery depends on your server’s mail configuration or any SMTP plugin you have installed.

Coupon Log Go to Generate Coupon Setting > Coupon Log in the WordPress admin to see a table of every coupon that has been generated by the plugin. The table shows the coupon code, the form it was generated from, and the date and time it was created. The log displays the 100 most recent entries in reverse chronological order.
