Stefin, your program is missing 1 line.

PHP Code:
$userInfo = mysqli_fetch_assoc($result); 
This need to be added after code

PHP Code:
if ($result->num_rows == 0) {
    die("User with email address <b>$email</b> not found");
} 
What that line do is fetch (means read, get, etc..) user information from MySQL query result.

@annie made that mistake (but actual code worked, i verified), @sherly copied it @stefin reported the mistake :D

@sherly

This is wrong code. You put code for index.html in lost_password.html

Please reupload the code, try to understand, if you don't understand ask here, that help everyone.

Now stefin asked the question, and we found a problem with posted codes.
