Redirect echo help

[99daocon]

I am new to PHP and I am a bit confused. I know its an easy solution but I can't get my head around it.

 

I have a form which is to send a message to a database.

After the form is sent it redirects you to another page.

This works fine, but I want it to give you some feedback, so basically say that your message has successfully been posted.

Here is my PHP:

 

form.php

 

<?php

function posted(){

global $redirect;

include 'formindb.php';

if $redirect = true;{

echo "Your message has been posted";

}

}

?>

 

formindb.php

 

$redirect = header("Location: form.php");

You can't really use a header after output, so you would use a HTML redirect instead.

Ok so I put this at the end of my php file which sends the form to the database

 

<meta http-equiv="Refresh" content="5; url=/CMS/TEST/form.php">

 

The page says that your message has succesfully been posted then redirects back to the form, but thats not really what I wanted.

It will do though.

 

I would have prefered setting the redirect as a variable, which is true when redirected, and false when not.

So I would include the variable on the other page and if it is true it would echo your message has been posted, if false it wouldnt do anything. Is that possible?

Sure, you can use a session for that or put a setting in a URL like

 

mypage.php?success=yes

 

Then on your other page, use $_GET['success'], and if yes echo something, if empty or no, do something else.

Any examples?

 

I have a basic understanding of session but I am confused as to how it would work in this situation.

Sorry for being a pain.

Sessions are just another variable.

 

On success, just set $_SESSION['success'] = "yes";

 

On your other page, just read  $_SESSION['success'] to see if it == "yes"

 

Make sure you use session_start(); at the top of each page that uses sessions.
