You UPDATE query is wrong, you wrote:

UPDATE table SET() WHERE VALUES();

Change it to:

UPDATE users
SET userid = '$_POST[userid]',
firstname = '$_POST[firstname]',
lastname = '$_POST[lastname]',
email = '$_POST[email]',
username = '$_POST[username]',
password = '$_POST[password]',
role = '$_POST[role]')
WHERE condition = 'value';

Check this for more info: http://dev.mysql.com/doc/refman/5.5/en/update.html
And remember to sanitize data.

Hello,
I've done it like that:

$sql="UPDATE users SET userid = ('$_POST[userid]',firstname = '$_POST[firstname]',lastname = '$_POST[lastname]',email = '$_POST[email]',username = '$_POST[username]',password = '$_POST[password]',role = '$_POST[role]') WHERE condition = 'value'";

and ive got still problem probobly with ""

Try this:

$sql="UPDATE users SET 
        userid = '$_POST[userid]',
        firstname = '$_POST[firstname]',
        lastname = '$_POST[lastname]',
        email = '$_POST[email]',
        username = '$_POST[username]',
        password = '$_POST[password]',
        role = '$_POST[role]'
        WHERE condition = 'value'";

Remove those parentheses after userid = and before WHERE.

Hello,
got all the time =/

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 'condition = 'value'' at line 9

[cereal]

condition = 'value' is just an example, you have to choose your condition for the WHERE statement, for example, basing on your table write: userid = '$_POST[id]'

Hello,
okay every thing works like a charm thanks for help and sorry for the newbie behavior, have a nice day =]

[cereal]

No problem, change $_GET['userid'] to $_POST['userid'] and it should work. As in my previous post (I edited that post changing $_GET with $_POST after I checked your previous script).
