How send-otp.php and sendMail.php Work Together

1️⃣ send-otp.php – Generates OTP and Calls sendMail.php

• This script handles the OTP generation and stores it in the database.
• After storing the OTP, it calls sendMail() to send an email.

2️⃣ sendMail.php – Sends the Email

• This script uses PHPMailer to send the email.
• It receives the email body and sends the email via SMTP.

📌 How They Work Step-by-Step

1️⃣ User Requests OTP (JavaScript)

• The front-end (JavaScript) sends an AJAX request to send-otp.php when the user enters an email.

2️⃣ send-otp.php Handles the Request

✔️ Extracts the user's email from $_POST.
✔️ Validates the email format.
✔️ Generates a random 6-digit OTP.
✔️ Stores the OTP in the database (otp_codes table).
✔️ Prepares the email body (HTML format).
✔️ Calls sendMail() function to send the email.
✔️ Returns a JSON response to the front-end.

3️⃣ sendMail.php Sends the Email

✔️ Uses PHPMailer to send an email via SMTP.
✔️ Configures SMTP settings (host, username, password, encryption, port).
✔️ Sends the email to the user with the OTP.
✔️ Logs errors if the email fails.
