PHP and redirection

Question

I am fairly new to this site and have a question about a problem that I have recently. How to interact with a page on which we just made a redirection? That is, after validating a form, I would like to be able to redirect the user to the login page and show him a success message such as: Successful registration! But I can not do it.

Not the prettiest solution, but it will work.

The header function can be used to redirect a user to a page.

header("Location: myFile.php?message=success"); // success can be changed to fail

You can then use this code on the destination page to display the message accordingly.

if(isset($_GET['message'])) {

    if($_GET['message'] == 'success') {
        echo 'Registered successfully!';
    } elseif($_GET['message'] == 'fail') {
        echo 'Registration failed.';
    }

}

To do a redirect use the header() function:

header("Location: [you-url]");

To show a message I suggest you use $_SESSION[] or $_GET[] both of these variables are superglobal variables:

http://php.net/manual/en/language.variables.superglobals.php

Also remember if you use $_SESSION[] then you have to put session_start() at the beginning of each page...

TRY THIS ($_SESSION[]session solution):

$_SESSION['message'] = "Successful Registration";
header("Location: [redirect-url]");

On the display page:

<?php

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

?>

TRY THIS ($_GET[] solution):

header("Location: [redirect-url]?message=Successful%20Registration");

On the display page:

<?php

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

?>

You can change these up depending on if it failed or not!

Your `$_GET` solution won't work since you have a space in the parameter. You should change the space to `%20`. – rpm192 Nov 04 '18 at 19:39
@rpm192 Usually it auto adds it but I changed it anyway – Nov 04 '18 at 20:09
You added it to the `$_SESSION` one, I was talking about the `$_GET` one. – rpm192 Nov 04 '18 at 20:11
@rpm192 my bad! – Nov 04 '18 at 20:17

I'd use $_SESSION variables to store the message you wish to display. Echo the contents of this $_SESSION variable when you want to show it and then UNSET() the variable once you're done
