copied!<p>In brief (since this is documented in various other places on the internet), magic methods are for setting and getting data. These calls </p> <pre><code>$this->setSomeThing('value'); $this->getSomeThing(); </code></pre> <p>are equivalent to these calls</p> <pre><code>$this->setData('some_thing','value'); $this->getData('some_thing'); </code></pre> <p>The string <code>'some_thing'</code> is a data key. To set and get data with a magic method is this key is CamelCased into 'SomeThing'. </p> <p>You can see <strong>all</strong> the data properties (and therefore derive the magic methods) with a parameterless call to 'getData'</p> <pre><code>var_dump( $this->getData() ); </code></pre> <p>Be careful with <code>var_dump</code> if you're not using <code>xDebug</code>, and many Magento objects are too large and/or too circular to fully display. If you're running into that problem, you can just peek at the keys with </p> <pre><code>var_dump( array_keys($this->getData()) ); </code></pre> <p>That's all magic methods are for in Magento — getting and setting data.</p> <p>Play around with this using a varien object, which is the object all Models and Blocks inherit from in Magento.</p> <pre><code>$o = new Varien_Object; $o->setData('foo','bar'); var_dump($o->getData('foo')); var_dump($o->getFoo('foo')); var_dump($o->getData()); </code></pre> <p>One last thing to keep in mind: If an object's class has a method defined with the same name as a magic method,the magic method is ignored. Sometimes the only way to know for sure if something is a magic method or a real method is to go look at the class definition. </p>
