Let´s play araound and create a nice Theme for Constructr CMS. We will build a simple basic PHP-based Theme. We will have Page Titles, a Typo Head – linked to the Root-Level, an static Intro Section, a Text based Navigation and a Content Section. Thats all we need for our first Theme. How to create the Page-Titles? Take a Look at the following simple Code:
<?php
//Including some neccessary Files
require_once(‘data/config/config.inc.php’);
require_once(‘data/config/constructr_define.inc.php’);
require_once(‘content_decoder.inc.php’);
require_once(‘data/php/constructr.class.php’);
// Grabbing the actual Host and URL
$host = $_SERVER['HTTP_HOST'];
$uri = rtrim(dirname($_SERVER['PHP_SELF']), ‘/\\’);
// Creating some Paths for including Grafix, linking to CSS and Javascript
$ROOT_PATH = ‘http://’ . $host . $uri;
$IMG_PATH = ‘http://’ . $host . $uri . ‘/data/workspace/pix/’;
$CSS_PATH = ‘http://’ . $host . $uri . ‘/data/workspace/css/’;
$UPL_PATH = ‘http://’ . $host . $uri . ‘/data/workspace/uploads/’;
$JS_PATH = ‘http://’ . $host . $uri . ‘/data/workspace/js/’;
// Open the main Database Connnection to grab Pages and Content
$db =& new constructr($HOST,$USER,$PASSWD,$DATABASE);
?>
First, we include all the needed Files to interact with Constructr CMS. The $host and $uri Section is needed for the Navigation and the inclusion for the following Paths. In the next Part we set some relative Links for Images, CSS-Files, the Uploads and Javascript. Finaly we create the DB-Connection. That´s the Head of our main index.php-File.
<!DOCTYPE html
PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN”
“DTD/xhtml1-strict.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml” xml:lang=”de” lang=”de”>
<head>
<meta http-equiv=”content-type” content=”iso-8859-1″ />
<link rel=”stylesheet” type=”text/css” href=”<?php echo $CSS_PATH; ?>style.css” />
Above You will see the HTML-Head with the included CSS-File for the Style. The main Template FIle is a simple PHP-Document.
<?php
if(!isset($_GET['show_page']))
{
echo ‘<title>My Page Title</title>’;
}
else
{
echo ‘<title>My Page Title – ‘ . strtoupper($_GET['show_page']) . ‘</title>’;
}
?>
</head>
<body>
Above you will see the simple Creation of the Page Titles. The “$_GET['show_page']” is our Page Alias we will get from the CMS-Logic, to select the rght Content and more.
We just take the $_GET['show_page'] and transform it into uppercase Letters – thats all.
<div id=”head”>
<div id=”inner_head”>
<h1><a href=”<?php echo $ROOT_PATH; ?>”><span class=”orange”>My Typo Head – Could be a Graphic too</span></a></h1>
<p>

</p>
</div><!–EOF DIV INNER_HEAD–>
</div><!–EOF DIV HEAD–>
This will be our Head-Section of the Template. We link the Typo-Logo to the Root-Path we created above. Then follows a static Part – it will be the same at every Page.
<div id=”navigation”>
<div id=”inner_navigation”>
<p>
<?php
$get_pages = $db -> query(”
SELECT *
FROM $DB_TABLE_CONSTRUCTR_PAGES
WHERE page_visibility = ‘1′
ORDER BY page_lft ASC
“);
while ($all_pages = $db -> fetch_array($get_pages))
{
$page_id = $all_pages['page_id'];
$page_name = $all_pages['page_name'];
$page_alias = $all_pages['page_alias'];
$page_lft = $all_pages['page_lft'];
$page_class = $all_pages['page_class'];
$ACT_SHOW_PAGE = $_REQUEST['show_page'];
if(isset($ACT_SHOW_PAGE) && $ACT_SHOW_PAGE == $page_alias)
{
if($page_lft == ‘1′)
{
echo ‘<a href=”http://’ . $host . $uri . ‘/” title=”http://’ . $host . $uri . ‘/” class=”orange”>’ . $page_name . ‘</a>’;
}
else
{
echo ‘ <a href=”http://’ . $host . $uri . ‘/’ . $page_alias . ‘/” title=”http://’ . $host . $uri . ‘/’ . $page_alias . ‘/” class=”orange”>’ . $page_name . ‘</a>’;
}
}
else
{
if($page_lft == ‘1′)
{
echo ‘<a href=”http://’ . $host . $uri . ‘/” title=”http://’ . $host . $uri . ‘/”>’ . $page_name . ‘</a>’;
}
else
{
echo ‘ <a href=”http://’ . $host . $uri . ‘/’ . $page_alias . ‘/” title=”http://’ . $host . $uri . ‘/’ . $page_alias . ‘/”>’ . $page_name . ‘</a>’;
}
}
}
?>
</p>
</div><!–END OF INNER_NAVIGATION–>
</div><!–END OF NAVIGATION–>
That´s all we need for displaying the Navigation. We just select all visible Pages orderd by page_lft (Nested Sets-Structure).
<div id=”content”>
<div id=”inner_content”>
<?php
if(!isset($_GET['show_page']))
{
$get_page_id = $db -> query(”
SELECT *
FROM $DB_TABLE_CONSTRUCTR_PAGES
WHERE page_lft = ‘1′
LIMIT 1
“);
$act_page_id = $db -> fetch_array($get_page_id);
$page_id = $act_page_id['page_id'];
$page_name = $act_page_id['page_name'];
$page_class = $act_page_id['page_class'];
$get_page_content = $db -> query(”
SELECT *
FROM $DB_TABLE_CONSTRUCTR_CONTENT
WHERE page_id = ‘$page_id’
AND visibility = ‘1′
ORDER BY sort ASC
“);
$content_counter = $db -> num_rows($get_page_content);
if($content_counter != 0)
{
while ($act_content = $db -> fetch_array($get_page_content))
{
$id = $act_content['id'];
$page_id = $act_content['page_id'];
$content = $act_content['content'];
$visibility = $act_content['visibility'];
$sort = $act_content['sort'];
echo unhtmlentities(base64_decode($content));
}
}
else
{
echo ‘No Content available on Page ‘ . $page_name;
}
}
else
{
$db =& new constructr($HOST,$USER,$PASSWD,$DATABASE);
$host = $_SERVER['HTTP_HOST'];
$uri = rtrim(dirname($_SERVER['PHP_SELF']), ‘/\\’);
$show_page = $_REQUEST['show_page'];
$get_page_id = $db -> query(”
SELECT *
FROM $DB_TABLE_CONSTRUCTR_PAGES
WHERE page_alias = ‘$show_page’
LIMIT 1
“);
$act_page_id = $db -> fetch_array($get_page_id);
$page_id = $act_page_id['page_id'];
$page_name = $act_page_id['page_name'];
$get_page_content = $db -> query(”
SELECT *
FROM $DB_TABLE_CONSTRUCTR_CONTENT
WHERE page_id = ‘$page_id’
AND visibility = ‘1′
ORDER BY sort ASC
“);
$content_counter = $db -> num_rows($get_page_content);
if($content_counter != 0)
{
while ($act_content = $db -> fetch_array($get_page_content))
{
$id = $act_content['id'];
$page_id = $act_content['page_id'];
$content = $act_content['content'];
$visibility = $act_content['visibility'];
$sort = $act_content['sort'];
echo unhtmlentities(base64_decode($content));
}
}
else
{
echo ‘No Content available on Page ‘ . $page_name;
}
}
?>
</div><!–EOF DIV INNER_CONTENT–>
</div><!–EOF DIV CONTENT–>
Thats all we will need to grab the Content from our Database.
We need a Footer:
<div id=”footer”>
<div id=”inner_footer”>
© <?php echo date(‘Y’); ?> Alle Rechte vorbehalten. Webdesign & Programmierung <a href=”http://phaziz.com/”>phaziz <span class=”pink”>interface</span> design</a>.
</div><!–EOF INNER_FOOTER–>
</div><!–EOF FOOTER–>
Static Content with a little PHP for displaying the actual Year. And now, close the HTML-File and the Database Connection:
</body>
</html>
<?php
$db -> close();
?>
We are done! Thats all we need to create a individual Theme for Constructr CMS – a little HTML, a nice CSS-Style and a little PHP for grabbing the Page-Title, the Navigation and the Content.
