Store 3 as 1

[Dysan]

How do i store data from three textboxs, as one field?
e.g.

If textbox 1 contains "one", textbox 2 contains "two", and textbox 3 contains "three", then the field should contain "onetwothree".

<?php

$sql="INSERT INTO Person (Firstname, Lastname, Sex)
VALUES
('$_POST[Firstname]','$_POST[Lastname]','$_POST[Sex]')";

if (!mysql_query($sql,$con))
{
  die(mysql_error());
}
echo $_POST[Name] . "'s Record Added Successfully!";

mysql_close($con)
?>

could you just concatenate those variables?By the way don't insert user input straight from $_POST into your db, you would be vulnerable for SQL injections.

you need to filter input with mysql_real_escape_string() For other security issues checkout this article.

Use one textbox. Alternatively, have three fields in your table since it implies that those values are separate.
