addNewUser.php

Here i am doing validations and displaying error messages and if it is success sending him to another page.

But i want to show an error message on addUser.php instead of validations page. Please give me a sample code how i can do it.

Answer 1

addNewUser.php

Add the message in the session

$_SESSION["ErrorMsg"]="Name already exists";

And in your addUser.php , you put the following code in the place you need to show the msg :

if($_SESSION["ErrorMsg"])
{
  echo $_SESSION["ErrorMsg"];
  $_SESSION["ErrorMsg"]="";
}
