    <p>The approach seems right (Except you need to use $this-> to access the property), but: Do yourself a flavour and have a look at how getter and setter are normaly used. A getter should return something, while a setter sets something. If you need to do "something" internal, you should use another method, or even do it in the constructor, etc..</p> <pre><code>class Item{ public $itemid; public $itemattribute; function __construct($itemid){ $this-&gt;itemid = $itemid; } public function getItemId(){ return $this-&gt;itemid; } //option 1:) public function calculateAttributeValue(){ $this-&gt;itemAttribute = foo($this-&gt;itemid); } //option 2:) public function calculateAttributeValue($func){ $this-&gt;itemAttribute = $func($this-&gt;itemid); } //option 3:) (lazy loading) public function getItemAttribute(){ if ($this-&gt;itemAttribute == null){ $this-&gt;itemAttribute = foo($this-&gt;itemid); } return $this-&gt;itemAttribute; } //option 4 (eager loading) function __construct($itemid){ $this-&gt;itemid = $itemid; $this-&gt;itemAttribute = foo($this-&gt;itemid); } public function getItemAttribute(){ return $this-&gt;itemAttribute; } } </code></pre> <p>However it is a GOOD idea, to either use eager OR Lazy loading. Whenever you need to "call" another function in order to compute a value, BEFORE a getter will return a value, your design becomes sensitive to "calling the functions in the right order", which will be bad for large Classes, and even worse, if one calculation depends on another calculation done prior...</p> <p>Bad usagE:</p> <pre><code>$myClass = new Item(5); $myClass-&gt;CalulateA(); $myClass-&gt;CalculateB(); $myClass-&gt;getB(); </code></pre> <p>Better:</p> <pre><code>$myClass = new Item(5); //calculates A and B $myClass-&gt;getB(); </code></pre> <p>or</p> <pre><code>$myClass = new Item(5); $myClass-&gt;getA(); //calculates A. $myClass-&gt;getB(); //calculates B and A when required. </code></pre>

    1. COVery good and valuable input. I was wondering about performing all my populating functions when I initiated the class (eager loading i suppose).

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.
