PHP Pass Data with Redirect

Question

PHP Redirect with Post Data

Hi,

I am a newbie PHP programmer and trying to code a small blog.

I will explain what I am trying to do.

• page1.php: Has a table of all posts in the blog
• page2.php: This page has a form where you can add a Post

Page 2 posts to itself and then processes the data, if it successful then uses header() to redirect back to page1 which shows the table.

Now what I want to do is to be able to have a small message on page 1 above the table saying your blog post has been successfully submitted but I’m not sure how I can pass data back to page 1 after the form processing.

Answer 1

Set it as a $_SESSION value.

in page2:

$_SESSION['message'] = "Post successfully posted.";

in page1:

if(isset($_SESSION['message'])){
    echo $_SESSION['message']; // display the message
    unset($_SESSION['message']); // clear the value so that it doesn't display again
}

Make sure you have session_start() at the top of both scripts.

EDIT: Missed ) in if(isset($_SESSION['message']){

Answer 2

You could also just append a variable to the header location and then call it from the page.

header('Location: http://example.com?message=Success');

Then wherever you want the message to appear, just do:

if (isset($_GET['message'])) {    
   echo $_GET['message'];
}
