    <p>So basically I'm making a leap from procedural coding to OOP. I'm trying to implement the principles of OOP but I have a nagging feeling I'm actually just writing procedural style with Objects.</p> <p>So say I have a list of pipes/chairs/printers/whatever, they are all all listed as products in my single table database. I need to build a webapp that displays the whole list and items depending on their type, emphasis is on 'correct' use of OOP and its paradigm.</p> <p>Is there anything wrong about just doing it like:</p> <blockquote> <pre><code> CLass Show { public function showALL(){ $prep = "SELECT * FROM myProducts"; $q = $this-&gt;db-&gt; prepare($prep); $q-&gt;execute(); while ($row = $q-&gt;fetch()) { echo "bla bla bla some arranged display".$row['something'] } } </code></pre> </blockquote> <p>and then simply </p> <pre><code>$sth = new show(); $sth-&gt;showAll(); </code></pre> <p>I would also implement more specific display methods like:</p> <p>showSpecificProduct($id)->($id would be passed trough $_GET when user say clicks on one of the links and we would have seperate product.php file that would basically just contain</p> <pre><code>include('show.class.php'); $sth = new show(); $sth-&gt;showSpecificProduct($id); </code></pre> <p>showSpecificProduct() would be doing both select query and outputing html for display.</p> <p>So to cut it short, am I going about it allright or I'm just doing procedural coding with classes and objects. Also any ideas/hints etc. on resolving it if I'm doing it wrong?</p>

    1. COA good start would be to start thinking in terms of the Single Responsibility Principle: http://en.wikipedia.org/wiki/Single_responsibility_principle ('formatting html for display' could be considered a responsibility)

    2. COI think this is a very good question. Most people find it difficult to get their head around OOP to begin with, but it is *definitely* worth the effort. Asking questions will keep you away from bad habits and practices from the beginning.

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.
