A $_POST variable may not have a value, so you should do the following:

$name = isset($_POST['name']) ? mysql_real_escape_string($_POST['name']) : '';

or move the assignments within the if.

Add on: Your query is incorrect, check that you have the syntax right.

It's called the ternary operator, a shorthand if/else construct. See the manual, example #2.

suppose i fill the form and click the submit button.the pages not go to next page.but i includer the header funtion.header('location:register_success.php');

Did you fix your query, as I mentioned earlier ?

$query = " insert into users(name,username,emailid,password,)values ('$name','$username','$emailid','$password')";
i think query is correct

my table name is users. my table is create table users(id int(11) auto increment,name varchar(100),username varchar(100),email id varchar (100), password varchar(100), primary key(id));
