$row=mysqli_fetch_array($result);


$pass_encrypt=md5(mysqli_real_escape_string($db,$_POST['defaultcurrentPass']));


if($pass_encrypt == $row["password"]) {

$passnew_encrypt=md5(mysqli_real_escape_string($db,$_POST['changenewPass']));


$str=$db->query("UPDATE users set password='" . $passnew_encrypt . "' WHERE id='" . $_SESSION["userId"] . "'");

$message = "You have successfully changed your password.";

var defaultcurrentPass,changenewPass,RetypePassword,output = true;


defaultcurrentPass = document.frmChange.defaultcurrentPass;

changenewPass = document.frmChange.changenewPass;

RetypePassword = document.frmChange.RetypePassword;


if(!defaultcurrentPass.value) {

defaultcurrentPass.focus();

document.getElementById("defaultcurrentPass").innerHTML = "required";

output = false;

}

else if(!changenewPass.value) {

changenewPass.focus();

document.getElementById("changenewPass").innerHTML = "required";

output = false;

}

else if(!RetypePassword.value) {

RetypePassword.focus();

document.getElementById("RetypePassword").innerHTML = "required";

output = false;

}

if(changenewPass.value != RetypePassword.value) {

changenewPass.value="";

RetypePassword.value="";

changenewPass.focus();

document.getElementById("RetypePassword").innerHTML = "Both Password are not same";

output = false;
