Form submission to echo differently depending on user inputs.

Hello,

I have a simple form with just one text input and a submit button:

<form method="POST" action="results.php">
<label for="results_submit_code">Type in your code here:</label>
<input type="text" name="results_submit_code" value="?????">
<input type="submit" value="Submit" class="results_submit_button">
</form>

So ideally, what I want to happen is for the user to type in a unique code which they are given e.g. 0000, and then the form to echo out a message linked with 0000. Another user might have the code 1111. Using the same form, a different message would be echoed after inserting 1111.

I am thinking of making an array e.g.

<?php
$code = array();
$code [0000] = "message for 0000";
$code[1111] = "message for 1111";
?>

So I'm thinking maybe I put the array into the value? And using the if/else statements to say if 0000 is entered echo 0000? Not sure where to start really, all help much appreciated!

<?php
if(isset($_POST['results_submit_code'])){
     $code = array(0000 => "0000 Message", 1111 => "1111 Message");
     $result = $code[intval($_POST['results_submit_code'])];
     if($result != null){
          echo $result;
     }else{
          echo "No meesage for this code";
     }
}

?>

<form method="POST" action="results.php">
<label for="results_submit_code">Type in your code here:</label>
<input type="text" name="results_submit_code" placeholder="?????">
<input type="submit" value="Submit" class="results_submit_button">
</form>

Give that a try :D
