Hi all,
Im trying to add validation to a form to allow PHP to check before its sends the values to another page for them to be uploaded to a database.
The problem i have is that i have taken a, i thought simple PHP validating script off the net and i cant seem to get it to work, its just giving me a blank page. I dont know if the script is outdated, i dont think it is.
The script is here:
<?php
include("validation.php");
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Test Area</title>
<link rel="stylesheet" href="test.css" type="text/css" media="screen" />
</head>
<body>
<div id="container">

<?if(isset($_POST['send'])&amp;amp;amp;amp;amp;amp;amp;amp;&amp;amp;amp;amp;amp;amp;amp;amp;(!validateModel($_POST['model']) || !validatePrice($_POST['price']) || !validateDescription($_POST['description']) ) ):?>
<div id="error">
<ul>
<?if(!validateModel($_POST['model'])):?>

<?if(!validateDescription($_POST['description'])):?>

<?endif?>
</ul>
</div>
<?elseif(isset($_POST['send'])):?>
<div id="error" class="valid">

function validateDescription($description){

}
?>I can't spot the problem, any suggestions?
