<h1>Using CodeIgniter Drivers</h1> |
|

||

||
61 |
<p>Drivers are a special type of Library that has a parent class and any number of potential child classes. Child classes have access to the parent class, but not their siblings. Drivers provide an elegant syntax in your <a href="controllers.html">controllers</a> for libraries that benefit from or require being broken down into discrete classes.</p> |
|
62 |
||
63 |
<p>Drivers are found in the <dfn>system/libraries</dfn> folder, in their own folder which is identically named to the parent library class. Also inside that folder is a subfolder named <kbd>drivers</kbd>, which contains all of the possible child class files.</p> |
|
64 |
||
65 |
<p>To use a driver you will initialize it within a controller using the following initialization function:</p> |
|
66 |
||
67 |
<code>$this->load->driver('<var>class name</var>'); </code> |
|
68 |
||
69 |
<p>Where <var>class name</var> is the name of the driver class you want to invoke. For example, to load a driver named "Some Parent" you would do this:</p> |
|
70 |
||
71 |
<code>$this->load->driver('<var>some_parent</var>');</code> |
|
72 |
||
73 |
<p>Methods of that class can then be invoked with:</p> |
|
74 |
||
75 |
<code>$this->some_parent->some_method();</code> |
|
76 |
||
77 |
<p>The child classes, the drivers themselves, can then be called directly through the parent class, without initializing them:</p> |
|
78 |
||
79 |
<code>$this->some_parent->child_one->some_method();<br /> |
|
80 |
$this->some_parent->child_two->another_method();</code> |
|
