    <?php
$fn=$_POST['f_name'];

$gen=$_POST['sex'];
$dob=$_POST['dob'];
$em=$_POST['email'];
$un=$_POST['u_name'];
$pd=$_POST['pswd'];
$mb=$_POST['mob'];
$con=mysqli_connect('localhost','username','password','db')
   or die("Error connecting to database");
$query="INSERT INTO user_details(First_Name, Last_Name, Gender, DOB, Email_Address,
Username, Password, Mobile_No) VALUES                   
('$fn','$ln','$gen','$dob','$em','$un',SHA('$pd'),'$mb')";
echo $gen;
$result=mysqli_query($con,$query) 
  or die("Error querying the database");

mysqli_close($con);
$name=$fn.' '.$ln;
echo "<b>Welcome $name</b>";
    ?>
  </body>
</html>

What I am trying to do in this code is to take data from an HTML form and store it into a MYSQL database. I even thoroughly checked my database for any type conflicts or any datatype length issues but still I am not getting it.
I don’t know why it is showing >> Error quering the database ?
Thanks in advance.

    Change 

    $result=mysqli_query($con,$query) 
  or die("Error querying the database");

    to 

    $result=mysqli_query($con,$query) 
  or die($mysqli->error);

    This will provide you with the exact error message from the server .. docs are here
