Alright. So i got MikeD to fix my problem of showing different forms based on a selection in jQuery, but now I'm getting undefined "climate" on line 4 of sim.php

Sim.php

Code: Select all

$disaster = 20-($disaster * 2);

  $climate = 49;

$finalscore = $predators + $disaster + $climate + $food + $disease + $water;

I'm not sure why you're using Jquery in a form.
Although, i've found one thing in your jquery script that i think it is not being identified:

Code: Select all

$( "select#climate" ).change(function()

This will use the select tag with the id of climate. And in your select you are only saying that the name of the select is climate, not the ID. I don't think that's the same.

Other than that.. you don't seem to have a select called climate to send the POST["climate"], thus saying it is not defined.

Hope that's the problem

Yep, you need to actually give the SELECT tag a name="climate". ID is not picked up on the server-side.

Oh okay. He probably meant for me to do that, but I neglected to do so. Also, I'm using jQuery because I just want climate to be shown, then depending on which climate you choose, a different form appears

Aye. And I thought I did everything right. It's undefined in sim.php on line 4

You need to form your HTML better, I think. You are just lumping everything into the HTML tag. Try copy and pasting all of your code that needs to output HTML to be displayed in the browser into this template:

Code: Select all

<!doctype html>

<html lang="en">
<head>
  <meta charset="utf-8">

  <title>The HTML5 Herald</title>
  <meta name="description" content="The HTML5 Herald">
  <meta name="author" content="SitePoint">

  <link rel="stylesheet" href="css/styles.css?v=1.0">  
</head>

<body>
  <script src="js/scripts.js"></script>
</body>
</html>

Of course, if you are using jQuery's ready event, feel free to move any JS scripts back up to the head. But both a HEAD and BODY tag are required. When left out, strange things can happen, such as form data being malformed when sent to the server.
