/**
|
|
* CFormElementCollection implements the collection for storing form elements.
|
|
*
|
|
* Because CFormElementCollection extends from {@link CMap}, it can be used like an associative array.
|
|
* For example,
|
|
* <pre>
|
|
* $element=$collection['username'];
|
|
* $collection['username']=array('type'=>'text', 'maxlength'=>128);
|
|
* $collection['password']=new CFormInputElement($form, array('type'=>'password'));
|
|
* $collection[]='some string';
|
|
* </pre>
|
|
*
|
|
* CFormElementCollection can store three types of value: a configuration array, a {@link CFormElement}
|
|
* object, or a string, as shown in the above example. Internally, these values will be converted
|
|
* to {@link CFormElement} objects.
