Question “Build Your Own Database Driven Web Site Using PHP & MySQL" Chapter 3

Hello,

I am currently working on Chapter 3 in the book “Build Your Own Database Driven Web Site Using PHP & MySQL”. I am on the section that discusses Templates, One Controller and I am unable to get the examples in the book to work properly.

When I view the 'welcome' examples in my browsers (chrome and safari) the first name: and last name: inputfields appear however after filling out the form and hit the 'go' button nothing happens.

Here is the code:

index.php:

Code:

<?php
if (!isset($_REQUEST['first name']))
{
include 'form.html.php';
}
else
{
$firstname = $_REQUEST['firstname'];
$lastname = $_REQUEST['lastname'];
if ($firstname == 'Kevin' and $lastname == 'Yank')
{
$output = 'Welcome, oh glorious leader!';
}
else
{
$output = 'Welcome to our web site, ' .
htmlspecialchars($firstname, ENT_QUOTES, 'UTF-8') . ' ' .
htmlspecialchars($lastname, ENT_QUOTES, 'UTF-8') . '!';
}
include 'welcome.html.php';
}
?>

form.html.php

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>Form Example</title>
<meta http-equiv="content-type"
content="text/html; charset=utf-8"/>
</head>
<body>
<form action="" method="post">
<div><label for="first name">First name:
<input type="text" name="first name" id="first name"/></label>
</div>
<div><label for="lastname">Last name:
<input type="text" name="lastname" id="lastname"/></label>
</div>
<div><input type="submit" value="GO"/></div>
</form>
</body>
</html>

welcome.html.php

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>Form Example</title>
<meta http-equiv="content-type"
content="text/html; charset=utf-8"/>
</head>
<body>
<p>
<?php echo $output; ?>
</p>
</body>
</html>

Hi jrealist. Welcome to SitePoint.

This is not really my area, but I'll just make this point:

Have a look at this code:

Code:

<input type="text" name="first name" id="first name"/>

You can't have a gap in an id name (and probably name attribute also), so firstly try removing all those gaps and see if the form works any better. If not, it might be worth moving this thread to the PHP forum. Let us know how you go.
