    The error (unshown in your question) is based on this Contact no. being your column.

    First, it contains a space and a period. If that is your actual column name, you should consider renaming it to Contact_no or use backticks around it.

    I.e.:

    `Contact no.`

    or removing the period and rename it to (and in your DB):

    `Contact no`

    change to

    (FirstName, LastName, Address, City, `Contact no.`)

    or remove the period and rename it in DB to Contact no

    (FirstName, LastName, Address, City, `Contact no`)

    or rename it in your DB to Contact_no with an underscore

    (FirstName, LastName, Address, City, Contact_no)

    using that type of naming convention is not considered good practice. MySQL will complain about it.

    For more information on table/column indentifiers, visit the MySQL.com website:

    Also, remove all the isset from your variables.

    $first=mysqli_real_escape_string($con,$_POST['first']);

    etc.

    You may also be injecting characters that MySQL does not agree with, apostrophes, slashes etc.. Using only mysqli_real_escape_string is not sufficient. Add stripslashes()

    I.e.:

    $first=stripslashes($_POST['first']);
$first=mysqli_real_escape_string($con,$_POST['first']);

    etc.

    Using prepared statements would be easier to use.
