## 外掛說明

**Gravity Forms – OTP Verification** allows you to add **One-Time Password (OTP)
verification** to Gravity Forms, ensuring that users enter a valid mobile number
or email address before submitting a form. It helps prevent spam, fake submissions,
and ensures real user authentication.

### **Key Features:**

 * 🔒 **Secure Mobile Verification** – Ensures users verify their phone numbers 
   before submitting.
 * ✅ **Seamless Gravity Forms Integration** – Works with all versions of Gravity
   Forms without conflicts.
 * 🌎 **Supports Persian, Arabic & English Numbers** – Converts and validates all
   number formats.
 * 📡 **Flexible SMS Gateway Support** – Connects to multiple SMS providers via 
   built-in integrations or custom hooks.
 * ⚙️ **Easy Setup** – Configure in just a few clicks with user-friendly settings.

### Features

 * Add an Mobile OTP field to **any Gravity Form**.
 * Prevent form submission **until mobile verification is successful**.
 * Support for **multiple SMS gateways** including custom integrations.
 * Fully compatible with **Gravity Forms’ conditional logic**.
 * Users can **resend OTP** with a cooldown limit (e.g., **3 attempts, 90 seconds
   each**).
 * Supports **hooks & filters** to extend functionality.
 * Works across **all WordPress and WooCommerce sites**.

### Supported SMS Gateways

The plugin supports direct integration with popular SMS gateways as well as widely-
used SMS plugins. You can send OTP messages using your preferred SMS provider or
through supported SMS plugins for maximum flexibility.

 * **Plugin: WSMS (formerly WP SMS) (over 300 gateways)**
 * **Plugin: Persian WooCommerce SMS (over 100 gateways)**
 * **Iranian Gateway: SMS.ir (v1/v2)**
 * **Iranian Gateway: FarazSMS**
 * **Iranian Gateway: IPPanel**

### Supported Email Gateways

The plugin uses the default WordPress email sending function (`wp_mail`). This means
you are free to use **any email service** you want—whether it’s your web host’s 
built-in mail, your WordPress site’s configured SMTP settings, or a third-party 
SMTP plugin. Just configure your preferred email service, and OTP emails will be
sent using that method.

You can also fully customize the OTP email: set a custom sender name, sender address,
subject, and modify the email template as HTML directly from the plugin settings.

Additionally, you can add **any other SMS gateway** via **WordPress hooks and filters**.

### How to Setup the Plugin

 1. **Install & Activate** the plugin.
 2. **Go to Gravity Forms** and create a form.
 3. **Add the OTP Field** from the field settings.
 4. **Configure your SMS Gateway** in plugin settings.
 5. **Save your form**, and OTP verification will be active.

 * **Tippy.js**
 * **Select2.js**
 * **Datatables**
 * **jQuery Confirm**
 * **jQuery Repeater**
