how to check to see if passwords are identical??

[cluce]

Can someone tell me how to add an onclick behavior and tell it to do this ...

 

if (($_POST["password"]) !== ($_POST["confirmpassword"])){

echo ("passwords must be identical");

 

}else{

 

Instead of putting this on a second page and having duplicate pages to display the error message, I am trying to confirm the passwords before submitting or inserting a new record in the database and if they dont match have it display a message on the same page. Anybody have any ideas? I am using Dreamweaver 8 and PHP and mySQL.

if($_POST["password"]!==$_POST["confirmpassword"]){
$_SESSION[error]="passwords must be identical";
header(Location: login.php);
}

then on your login page, just echo that wherever...
