passing a variable from page2 to page1

[dudleylearning]

Hi All,

 

couldn't seem to figure how to pass data from page 2 to page 1. On page 2 I have this code block:

# if the form has been posted
if ($_SERVER["REQUEST_METHOD"] == "POST")
{
	# check for empty fields
	if (!empty(trim(($_POST['name'] == ''))))
	{
		$nameErr = "<span class=\"error\">Name is required</span>";
	}
	if (!empty(trim(($_POST['email'] == ''))))
	{
		$emailErr = "<span class=\"error\">Email is required</span>";
	}
	 
	# if all is fine, then add data to the database
	else 
	{
		$sql = 'INSERT INTO author SET
		name = :name,
		email = :email';
		
		$query = $dbConnection -> prepare($sql);
		$query -> bindValue(':name', $_POST["name"]);
		$query -> bindValue(':email', $_POST["email"]);
		$query -> execute();
		
		$message = 'done';
		header('Location: index.php');
		
	}
}

The variable $message I wanted to pass to page 1, where I have this in:

<?php if(isset($_POST['message'])) { echo $_POST['message']; } ?>

I can't seem to figure out the problem? Any tips?

 

Thanks

While you "could" post from one page to another, don't and use sessions.

<?php
// Page 1  
session_start();
$_SESSION['message']=$message;

 

<?php
// Page 2  
session_start();
echo($_SESSION['message']);

I was looking at using $_POST if possible, but couldn't figure it out from my trial.

You can't, at least not in your current workflow. You'd have to create an extra form which the user then has to submit only to help you pass internal data around – which obviously makes no sense. This also violates the purpose of POST request (which are meant to modify data).

 

Use a cookie, session variable or URL parameter. Anything but a POST request.

thanks for the tips. I did it through a URL parameter
