Step 5 - Creating our first view
All we need now is to pass the data above to a view. Let's create all our views in a "views" sub-folder.
<!-- views/view_BlogIndex.php -->
<?require_once("ViewHelper.php");?>
<?ViewHelper::DisplayHeader("Blog index");?>
<h1>Blog index</h1>
<p>You can <a href="index.php?cmd=BlogAddForm">add messages</a> !</p>
<form action="index.php" method="post">
Search: <input name="search">
<input type="submit" value="Search!">
</form>
<?
foreach($data as $message)
echo("<div class=\"message\">
<h2>{$message['title']}</h2>
<p>{$message['message']}</p>
<a href=\"index.php?cmd=BlogDelete&id={$message['id']}\">Delete this message</a>
</div>");
?>
<?ViewHelper::DisplayFooter();?>
The code itself it pretty simple. It loops through the data array using a foreach statement.
Note that instead of duplication the <HEAD> section in all our views, we have decided to move it to a helper function. All our views can then include the helper file and call the DisplayHeader and DisplayFooter function:
// views/ViewHelper.php
//############################################################################
// ViewHelper
//############################################################################
class ViewHelper
{
//############################################################################
// Displays HTML Header
//############################################################################
static function DisplayHeader($pageTitle = "")
{
echo("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
echo("<html>");
echo(" <head>");
echo(" <title>{$pageTitle}</title>");
echo(" <link type=\"text/css\" href=\"views/style.css\" rel=\"stylesheet\">");
echo(" </head>");
echo(" <body>");
}
//############################################################################
// Displays HTML Footer
//############################################################################
static function DisplayFooter()
{
echo(" </body>");
echo("</html>");
}
}
All you need now is to include your view from your command.
Update the doExecute() function as follow:
// Command_BlogIndex.php
//############################################################################
// doExecute
//############################################################################
function doExecute(Request $request)
{
// Create manager object
$manager = new ManagerMessage();
// Get data from database object
$data = $manager->getAllMessages();
// Include view
include("views/view_BlogIndex.php");
}
Note: I'll let you create your own style sheet, mine is boring anyway :)
Checkpoint
The home page of your blog should now be working!!!
