I Suppose you have created a MANY_MANY relation as given below.

Book Model:

 'authors' => array(self::MANY_MANY, 'Author', 'authorbook(book_id,author_id)'),

Author Model:

 'books' => array(self::MANY_MANY, 'Book', 'authorbook(author_id, book_id)'),

Note: authorbook is the table name containing ids

Make a selected checkBoxList

 $books = CHtml::listData(Book::model()->findAll(), 'id', 'name'); $selected_keys = array_keys(CHtml::listData( $model->books, 'id' , 'id')); echo CHtml::checkBoxList('Author[books][]', $selected_keys, $books);

checkBoxList function is taking three parameters.

Field name
Array of models ids those were previously selected
Options data

2nd parameter is important here, because it makes the checkBoxList selected.
