So far i write a code to store employee details in the database, and to send message in admin email heirs my code.
<?php
#database coding
if(!empty($_POST['txtfstname']) && !empty($_POST['txtlstname']) && !empty($_POST['txtemail']) && !empty($_POST['txtempno']))
{
$con=mysqli_connect("servername","username",'password',"database");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
// escape variables for security
$firstname = mysqli_real_escape_string($con, $_POST['txtfstname']);
$lastname = mysqli_real_escape_string($con, $_POST['txtlstname']);
$empno = mysqli_real_escape_string($con, $_POST['txtempno']);
$pass = substr(hash('sha256', mt_rand()), 0, 50);
$email = mysqli_real_escape_string($con, $_POST['txtemail']);
$email_code = md5($_POST['txtfstname'] + microtime());
if (!preg_match("/([\w\-]+\#[\w\-]+\.[\w\-]+)/",$email))
{
}
else
{
$sql="INSERT INTO empreg (first_name, last_name, email, emp_no, password, email_code)
VALUES ('$firstname', '$lastname','$email','$empno','$pass','$email_code')";
if (!mysqli_query($con,$sql))
{
die('Error: ' . mysqli_error($con));
}
echo "1 record added";
}
mysqli_close($con);
#email Coding
# It's best to just make sure each element isn't empty, using the empty() function.
# Note that if a field is not set, it is NULL, which is consdered empty, so there
# is no need to use the isset() function as well.
$firstname = trim(stripslashes(htmlspecialchars($_POST['txtfstname'])));
$lastname = trim(stripslashes(htmlspecialchars($_POST['txtlstname'])));
$email = trim(stripslashes(htmlspecialchars($_POST['txtemail'])));
$ip = $_SERVER['REMOTE_ADDR'];

{
# Return Error - Invalid Email
$msg = 'The email you have entered is invalid, please try again.';
}
else
{
# Sending the Email Message
# I moved this into the else clause. By putting it outside it was getting
# sent even if the email was invalid, which isn't exactly a good idea :)
$to = 'adminemail#something.com'; // Send email to receipient
$subject = 'Employee Registration'; // Give the email a subject
$message = 'From: ' . $firstname . "\r\r\n" . $lastname . "\r\r\r\n" . 'IP Address: ' . $ip; // Our message above including who sent it
$message_body .= "Please click on link to activate Employee \n\n email=$email $email_code ";
# Here I am capturing the return value of the mail() function so that I
# can check if it was actually successful. Just because the function is
# executed does not mean the email was sent. The return value tells us
# whether it was or not.
$success = mail($to,$subject,$message_body); // Send our email
if($success)
{
# The email was sent successfully!
$msg = 'Thank you for your message.';
}
else
{

$msg = 'An error occured. The mail could not be sent.';
}
}
}
else if (!isset($_POST['submit']))
{
# If the form hasn't been submitted yet, then do nothing. Do not prompt to enter a name just yet.
}
# One of the fields was empty. This finds out which one and creates a message
# to indicate which it was.

Answer 1

Ok, so, basically click the link, redirect this way:
The $user variable must be having the username of the user who is getting their account activated.
Activate
So, in the activate.php:
<?php
if(isset($_GET['user']) && strlen($_GET['user']) > 0) {
// Update the users activated status from 0 to 1 by running a query.
// Mail to the employee of his account activation
} else {
// No user selected.
}
To resolve the issue of the Mail being received in Spam folder, save the email to your contacts/unblock that email and it will be received in the Inbox.

Answer 2

I am not really experienced in PHP, but I have sent emails before using the mail() function.
To learn more about these you can look on:
W3Schools
Php Documentation
I hope this helps you :)
