This tells the browser to submit the form back to the same URL from which it received the form – in this case, the URL of the controller that included this template file. Let’s take a look at the controller for this example. Create an index.php script in the welcome directory alongside your form template. Type the following code into this file: <?php if (!isset($_REQUEST['firstname'])) { include 'form.html.php'; } else3 { $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($lastname, ENT_QUOTES, 'UTF-8') . '!'; } include 'welcome.html.php';5 } ?> This code should look fairly familiar at first glance; it’s a lot like the welcome8.php script we wrote earlier. Let me explain the differences: if (!isset($_REQUEST['firstname'])) { The first thing the controller needs to do is decide whether the current request is a submission of the form in form.html.php or not. You can do this by checking if the request contains a firstname variable. If it does, PHP will have stored the value in $_REQUEST['firstname']. isset is a built-in PHP function that will tell you if a particular variable (or array element) has been assigned a value or not. If $_REQUEST['firstname'] has a value, isset($_REQUEST['firstname']) will be true. If $_REQUEST['firstname'] lacks a value, isset($_REQUEST['firstname']) will be false. For the sake of readability, I like to put the code that sends the form first in my controller. What we need this if statement to check, therefore, is if $_REQUEST['firstname'] is not set. To do this, we use the not operator (!). By putting this operator before the name of a function, you reverse the value that function returns from true to false, or from false to true. Thus, if the request does not contain a firstname variable, then !isset($_REQUEST['firstname']) will return true, and the body of the if statement will be executed. include 'form.html.php'; If the request is not a form submission, the controller includes the form.html.php file to display the form. } else { If the request is a form submission, the body of the else statement is executed instead. This code pulls the firstname and lastname variables out of the $_REQUEST array, and then generates the appropriate welcome message for the name submitted: $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') . '!'; } Instead of echoing the welcome message, the controller stores the welcome message in a variable named $output. include 'welcome.html.php'; } After generating the appropriate welcome message, the controller includes the welcome.html.php template, which will display that welcome message. All that's left is to write the welcome.html.php template. Here it is: <!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>
