copied!<p>Let's imagine for a minute that your <code>Mcourse</code> table is called <code>courses</code> and model for that table is called <code>Courses</code>, your <code>Lcourse</code> table is called <code>courses_colleges</code> and your colleges table is <code>colleges</code> and model for that table is <code>Colleges</code></p> <p>Now, You should have <code>Courses</code> model with relations:</p> <pre><code>public function relations() { return array( 'colleges' => array(self::MANY_MANY, 'Colleges', 'courses_colleges(course_id, college_id)') ); } </code></pre> <p>Your <code>Colleges</code> model should have similar relations:</p> <pre><code>public function relations() { return array( 'courses' => array(self::MANY_MANY, 'Courses', 'courses_colleges(college_id, course_id)') ); } </code></pre> <p>Now if you want to print out a dropdown with all courses available for a certain college. In your controller action method get the model of that college including its courses:</p> <pre><code>public function actionShow() { $id = 1; // We set just some sample id. You could get it from request ofc. $college = Colleges::model()->with('courses')->findByPk($id); $this->render('show', array('college'=>$college)); } </code></pre> <p>Now in your view print out this:</p> <pre><code>echo CHtml::dropDownList('courses', '', CHtml::listData($college->courses, 'id', 'name')); </code></pre> <p>Where <code>'id'</code> and <code>'name'</code> are columns of your <code>Courses</code> model.</p> <p>Something like that.</p>
