    <p>It's the first time I use OOP with PHP 5.. so this is my problem..</p> <p>I have a file <code>disp.php</code> that contains a class named class disp (model in MVC)</p> <pre><code>&lt;?php class disp{ public $n_pages; public $current_page; private $cmd2; /***************SQL command generator*******************/ private function getCmd2($cmd1,$id,$first_entry,$perpage,$tri){ $cmd2=str_replace('COUNT(*)','*',$cmd1); $cmd2=$cmd2.' ORDER BY '.$id.' '.$tri.' LIMIT '.$first_entry.','.$perpage; return $cmd2; } /********************Items display******************/ function dispItems($cmd1,$id,$perpage,$tri){ require('global/connection.inc.php'); try{ foreach($pdo-&gt;query($cmd1)as $r){ $n_pages=ceil($r[0]/$perpage); if (isset ($_GET['pg'])){ $current_page=intval($_GET['pg']); if ($current_page&gt;$n_pages){ $current_page=$n_pages; } if ($current_page&lt;=0){ $current_page=1; } } else{ $current_page=1; $_GET['pg']=1; } } $i=1; $first_entry=($current_page-1)*$perpage; $objet=new disp(); $cmd2=$objet-&gt;getCmd2($cmd1,$id,$first_entry,$perpage,$tri); $data=array(); $i=0; foreach($pdo-&gt;query($cmd2) as $r){ $data[$i]=$r; $i++; } return $data; }catch(PDOException $e){} } } </code></pre> <p>this is the file <code>news.php</code> (controller in MVC):</p> <pre><code>require MODELS_DIR.'disp.php'; $objet=new disp(); $news=$objet-&gt;dispItems('SELECT COUNT(*) FROM tbl_nouveautes','ID_EVENT',10,'DESC'); $c_page=$objet-&gt;$current_page; $n_pages= $objet-&gt;$n_pages; require VIEWS_DIR.'disp-news.php'; </code></pre> <p>in this code, I created an object (objet) of the type disp... I want to use the variables declared in the function <code>dispItems</code>, (<code>$n_pages</code> and <code>$current_page</code>) in the view (<code>disp-news.php</code>)</p> <p>so I think that the class variables are the same variables in the function <code>dispItems()</code>... but when trying to access them from the controller ...using object. it shows me a error :</p> <p>See:</p> <pre><code>Notice: Undefined variable: n_pages in C:\Program Files\EasyPHP-5.3.6.1\www\example\admin\global\news.php on line 14 Fatal error: Cannot access empty property in C:\Program Files\EasyPHP-5.3.6.1\www\example\admin\global\news.php on line 14 </code></pre> <p>Inspite of <code>$n_pages</code> and <code>$current_pages</code> being public in the class disp</p> <p>thank you in advance</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
