how can i display the form error if the form action is some other page than itself.
for example, i have a form, after submitting it goes to validate_form.php page. There i assign error to a variable, eg. $error = "Please enter your name";
Now i want to print this error on the original form page, how can i get this $error value on the form page ?
thanks.

You could set the error message in a session variable, or pass it as a GET parameter back to the original page. I'd be more inclined to use the first option but either is fine

validate_form.php

PHP Code:

// Validate form
if ($form_does_not_validate) {
     $_SESSION['formError'] = "There was an error...";
     header("Location: form.php");
     exit();
} 

form.php

PHP Code:

// If an error is set
if (isset($_SESSION['formError'])) {
     echo $_SESSION['formError'];
} 

or

validate_form.php

PHP Code:

// Validate form
if ($form_does_not_validate) {
     header("Location: form.php?formError=1");
     exit();
} 

form.php

PHP Code:

// List of error messages that are possible
$errorList[0] = "Fields were left empty".
$errorList[1] = "You did not agree to the terms and conditions";
$errorList[2] = "blah blah...";
// and so on

// If an error is set
if (isset($_GET['formError'])) {
     echo $errorList[ $_GET['formError'] ];
}
