Okay so I set up a registration form and everything goes well when registering but when I go and check in MySQL database the row is created but only the id field is filled not the First Name, Second Name, Email and Password.

Here's the .PHP for processing the registration :

mysql_select_db("mlsconnection_99k_dbusers", $con);

$sql="INSERT INTO Persons (FirstName, LastName, Email, Password)
VALUES
('$_POST[firstname]','$_POST[lastname]','$_POST[Email]','$_POST[Password]')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
echo "User created, Thanks for Registrating";

mysql_close($con)
?>

ALLWAYS use mysql_real_escape_string()
or you will be hacked read http://www.php.net/manual/en/security.database.sql-injection.php

mysql_select_db("mlsconnection_99k_dbusers", $con);

$sql="INSERT INTO Persons (FirstName, LastName, Email, Password)
VALUES
(".mysql_real_escape_string($_POST[firstname])."','".mysql_real_escape_string($_POST[lastname])."','".mysql_real_escape_string($_POST[Email])."','".mysql_real_escape_string($_POST[Password])."')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }
echo "User created, Thanks for Registrating";

mysql_close($con)

Thanks for the help =)

Got any idea why doesn't the form fill the rows?

refering to array's in a string doesn't work

sql= "bla $_POST[lastname] bla";

wrong (bla bla)

sql= "$lastname"

ok

sql= "bla ".$_POST[lastname]."bla";

also ok

Don't understand you xD how should the code look like? what should I change? :)

the code i posed shoud work
(didn't test)

It gave an error: Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '','','','')' at line 3

you must use

$_POST['lastname']

not

$_POST[lastname]

sorry i didn't seed that
