@NogDogNov 02.2013 — #Easiest(?) way is to use a single page for everything, so that the form page submits to itself. Then you add logic up front to determine whether or not this is a form submission (usually by checking for some $_POST or $_GET element), in which you case you process it, else if not, then you display the form. If the form submission fails, then you can display the form along with a message, plus the values are already there in $_GET or $_POST if you want to use them to prefill the form with what the user had entered.
You may want to make the form page itself a separate file that you can require() as needed, and you could do the same with the "success" page.
How to display a message on another page
I am working on a form for a survey. It is very simple as it only has three radio buttons. After the form is submitted, I have another PHP page handling the form. I am using isset to check to see if each one was ticked. If one was not ticked, I want to display a message asking the user to answer each one. On the other hand, I also want to display a message how can I pass a message once the form is successfully completed. I know how to easily do this in JavaScript but no in PHP.
Anyone care to help me out? Below is the code I have:
This is where I want to display the message. The page that contains this is only a PHP page and not an HTML page. Thanks to anyone that takes a look at this.
<span name=”message”> </span>
[code=php]
session_start();
<?php
if(!isset($_POST[‘whereBuyBooks’]) ||
!isset($_POST[‘rent’]) ||
!isset($_POST[‘usefulness’])){
//How do I get this on the survey page??
$message = ‘Please answer each question’;
}
//Grabs data from form
$whereBuyBooks = $_POST[‘whereBuyBooks’];
$rent = $_POST[‘rent’];
$usefulness = $_POST[‘usefulness’];
//Grabs current time
$curtime = date(“Y-m-d H:i:s”,time());
// Formats data before writing to file
$data = ‘New survery taken on: ‘ .$curtime.”n”;
$data .= ‘Where students buy most books: ‘ .$whereBuyBooks . “n”;
$data .= ‘Do you rent texbooks: ‘ .$rent. “n”;
$data .= ‘How useful do you find our site: ‘ .$usefulness. “nnnn”;
$filename = ‘survey.txt’;
file_put_contents($filename, $data, FILE_APPEND);
//How do I get this on the survey page??
$message = ‘Thank you for completing our survey’;
header(“Location: index.php”);
?>
