Yii Model Behavior: Reduces annoying need to check if model attributes and relations are empty

ESelector

Reduces annoying need to check if model attributes and relations are empty/null/undefined.

Install

1. Place ESelector in your extensions directory

2. Attach the ESelectorBehavior to your model or base model

public function behaviors()
{
	return array(
		'ESelectorBehavior'=>'ext.ESelector.ESelectorBehavior',
	);
}

##Examples

echo $model->selector('title', 'NO TITLE'); 

The above is equivalent to:

if( empty($model->title) ) {
	echo 'NO TITLE';
} else {
	echo $model->title;
}

###ESelector also works with relationships

echo $model->selector('contact.fullname', 'No Name');
echo $model->selector('contact.address.city', 'No City');

The above is equivalent to:

if( !is_null($model->contact) && !empty($model->contact->fullname) ) {
	echo $model->contact->fullname)
} else {
	echo 'No Name';
}
if( !is_null($model->contact) && !is_null($model->contact->address) && !empty($model->contact->address->city) ) {
	echo $model->contact->address->city;
} else {
	echo 'No City';
}

##Wow ESelector is so much easier!
