Create Wordpress plugin to auto generate coupons for Gravity Forms

We want to create a custom plugin that will auto create coupon codes for Gravity Forms. We currently have a custom coded solution that does this, but we want it built as part of the UI, so that we can easily create these for each form. Part of this functionality is adding restrictions for the coupons based on selections, this is not a core part of GF coupons and will need to be built. We have created a simple example of this which you can use as a basis for your code. I will provide FTP, WP and cPanel access to our site for you to build this and can provide support if needed. Project details are below.


- When creating a new form, this plugin will add a new item under the 'Settings' for the form (currently contains: Form Settings, Notifications, Confirmations, etc.). The new settings page will have options to allow GF to create unique coupon codes upon form submission. The generated coupon code can be included as a merge tag in the confirmation or notification. After receiving the coupon code a customer can use it on other forms for a discount.

Example User Workflow

- User goes to form "Enter your email to get a discount coupon"

- User fills out the form

- User gets an email with their unique coupon code and a link to a different registration form

- User uses the coupon code on that form for the discount

1. When editing or creating a form, add a new items under 'Settings' called 'Auto Create Coupon'

2. This settings page will have these options (these 7 are same as current coupon options):

- Applies to Which Form?: Select dropdown with list of existing Gravity Forms. First option is 'Any Form'

- Coupon Prefix: Text field where user can add a prefix to the randomly generated coupon code

- Coupon Amount: Two fields:

> Dropdown: to select: Flat($) or Percentage(%)

> Text: Input either the flat discount or percentage discount of the coupon

- Start Date: Date when the coupon starts being valid

- End Date: Date when the coupon stops being valid

- Usage Limit: Number of times the coupon can be used

- Is Stackable: Checkbox, can be used with other coupons

3. Coupon Restrictions: These are also on the settings page, but are different from existing options. These settings are used to limit the coupon to certain options on a form. It would work similar to the Gravity Forms 'Conditional' settings. Fields in this section are:

- Enable Conditions: Checkbox to allow conditions or disable

- Source Form: Dropdown: Select from existing forms, this field will determine which fields are available for the conditional logic.

- Rules: See attachment. This section will include the rules that determine if a coupon should be allowed to be used on a form. For example, the coupon may be valid if: City = New York OR City = San Francisco.

> This type of logic appears in numerous other areas and I'm hoping that the UI code can be imported without building a custom solution.

> If the conditional logic code cannot be imported, then we may want to build these out as 'Feeds.' Feeds have built in options to add and save conditional logic. Our usage wouldn't exactly match Gravity Forms, but I think that could be customized more easily to match our goal.

> If the existing conditional logic UI cannot be used, then this can be simple text fields like 'input_7' 'equals' 'New York'. Where the user would just type in field ids, conditions and strings to match.

> Ultimately, how the field is built , is up to you. I haven't researched exact options, so you should go with the best solution you find. The functionality must allow the user to input fields and matching values. Must allow for 1 or more conditional statements and allow them to be evaluated using OR or AND.

4. Create the coupon upon form submission.

- Write PHP code to create a new coupon whenever a user submits the form. The created coupon should have the settings selected in the form options. Most options match to existing settings. The 'Conditional' options may need to be stored in post_meta or some other way so they can be looked up later.

- In our site there is a plugin called 'gf-auto-coupon-generate' that does this. You may want to look at that code to see how it is handled.

5. Create Merge Tag that can be used to display the generated coupon code in Confirmations and Notifications.

- Create a merge tag {generated_coupon_code} that can be added in messages to display the unique coupon code that was created.

6. Create code to restrict coupon usage based on the conditional settings. (attachment #3)

- When a user enters the coupon on a form and clicks 'Apply,' we need to check if the coupon code matches the conditional restrictions. If not, it should return a message "This coupon is not valid for your current selections." If the message can be more specific about which field, that would be great.

- GF has a hook called 'gform_coupons_can_apply_coupon' which can be used to limit coupon usage. In our [login to view URL] at line 2260 there is an example where we hard coded a restriction based on selected field values. To get this working, I had to modify core files in the 'gravityformscoupons' plugin. If you can get this restriction working without modifying core files, that would be best. Possibly, our plugin could fire a different AJAX call to handle the conditional check.

You can work on our live site, but be aware that people may be using this. Be very cautious not to bring the site offline. If you need a test environment, I can create a backup of our live site that you can use to build the plugin out. Would like to have this completed in about 2 weeks. Please let me know if you have any questions.
