I'm trying to create a website that allows for easy theme adding/manipulation like wordpress and other CMS systems do. To do this I'd like to make it so the theme file that delivers the content uses as little php code as possible. At the moment this is the (extremely simplified) class
class getparents {
var $parentsarray;
function get_parents() {
$this->parentsarray = array();
$this->parentsarray[] = array('Parent0',3,1);
$this->parentsarray[] = array('Parent1',8,2);
$this->parentsarray[] = array('Parent2',2,3);
return $this->parentsarray;
}
}
And retrieving it like this:
$parents = new getparents();
?><table><?php
foreach($parents->get_parents() as $rowtable)
{
echo "<tr><td>$rowtable[0] has category ID $rowtable[1] and is on level $rowtable[2] </td></tr>";
}
?></table><?php
But I want to make the retrieving more like this:
<table>
<tr><td><?php echo $cat_title; ?> has category ID <?php echo $cat_id; ?> and is on level <?php echo $cat_level; ?> </td></tr>
</table>
Which basically mean the class would just return the value in an understandable way and automatically keep on looping without the user having to add *foreach($parents->get_parents() as $rowtable)* or something similar in their theme file.
Here's an example wordpress page to (hopefully) illustrate what I mean. This page retrieves all posts for the current wordpress category which is what I'm trying to mimic in my script, but instead of retrieving posts I want to retrieve the category's parents, but I don't think it's important to explain that in detail.
<?php
/**
* The template for displaying Category Archive pages.
*
* @package WordPress
* @subpackage Twenty_Ten
* @since Twenty Ten 1.0
*/
get_header(); ?>
<div id="container">
<div id="content" role="main">
<h1 class="page-title"><?php
printf( __( 'Category Archives: %s', 'twentyten' ), '<span>' . single_cat_title( '', false ) . '</span>' );
?></h1>
<?php
$category_description = category_description();
if ( ! empty( $category_description ) )
echo '<div class="archive-meta">' . $category_description . '</div>';
/* Run the loop for the category page to output the posts.
* If you want to overload this in a child theme then include a file
* called loop-category.php and that will be used instead.
*/
get_template_part( 'loop', 'category' );
?>
</div><!-- #content -->
</div><!-- #container -->
<?php get_sidebar(); ?>
<?php get_footer(); ?>
Note: My actual question doesn't have anything to do with wordpress at all so I didn't add it as a tag.
UPDATE: I think my question may have been unclear. Here's a messy example (that works nevertheless)
index.php
<?php
include_once("class.php");
include_once("config.php");
if(isset($_GET['catid']))
{
$getproducts = new getproducts($_GET['catid']);
$catproductsarray = $getproducts->getarray();
$indexxx = 0;
foreach($catproductsarray as $rowtable)
{
include("templates/$template/all_products.php");
$indexxx++;
}
}
class.php
class getproducts {
var $thearrayset = array();
public function __construct($indexx) {
$this->thearrayset = $this->makearray($indexx);
}
public function get_id($indexxx) {
echo $this->thearrayset[$indexxx]['id'];
}
public function get_catID($indexxx) {
echo $this->thearrayset[$indexxx]['catID'];
}
public function get_product($indexxx) {
echo $this->thearrayset[$indexxx]['name'];
}
public function makearray($indexx) {
$thearray = array();
if(!is_numeric($indexx)){ die("That's not a number, catid."); };
$resulttable = mysql_query("SELECT * FROM products WHERE catID=$indexx");
while($rowtable = mysql_fetch_array($resulttable)){
$thearray[] = $rowtable;
}
return $thearray;
}
public function getarray() {
return $this->thearrayset;
}
}
templates/default/all_products.php
<!-- The below code will repeat itself for every product found -->
<table>
<tr><td><?php $getproducts->get_id($indexxx); ?> </td><td> <?php $getproducts->get_catID($indexxx); ?> </td><td> <?php $getproducts->get_product($indexxx); ?> </td></tr>
</table>
So basically, index.php gets loaded by user after which the amount of products in mysql database is taken from the class. For every product, all_products.php gets called with $indexxx upped by one.
Now the only thing the user has to do is edit the HTML all_products.php and the products will all be displayed differently. This is what I'm going for, but in a clean, responsible way. Not like this, this is a mess!
UPDATE2: I found a better way to do it, but added it as an answer. Seemed more fitting and pevents this question from getting any longer/messyer than it already is.
