Following is the code snippet from my processlogin.php file if(!$_POST["username"] || !$_POST["password"]) { $msg = "You left one or more of the required fields."; echo $msg; //header("Location:http://localhost/login.php"); } This code checks whether all the mandatory fields are filled on not. If not, it shows the error message. Till now everything is fine.

I want to show it above the login form in login.php file. How should I change my code to get my functionality. php html share|improve this question asked Nov 1 '13 at 6:58 user1556433 1 Use javascript or jquery instead of using php for validations –Shoaib Chikate Nov 1 '13 at 7:00 1 I would agree to use something like jQuery AJAX and get a JSON return that you can pass the error message in. It takes a little getting used to at first but can save you a bunch of headaches around this. Another option if you dont want to use javascript is to pass the error message in a session variable and do an isset($_SESSION['my_var']) ? $_SESSION['my_var'] : ""; on it –Cameeob2003 Nov 1 '13 at 7:07 add a comment| 8 Answers 8 active oldest votes up vote 7 down vote accepted I would prefer Jquery Validation or Ajax based Authentication. But still you can do it this way: Put your Error Message in Session like this : $_SESSION['Error'] = "You left one or more of the required fields."; Than simple show it like this: if( isset($_SESSION['Error']) ) { echo $_SESSION['Error']; unset($_SESSION['Error']); } In this case you can assign multiple messages in different Operations. share|improve this answer ed
