There are two main ways that you can do this. One of them is the standard CakePHP way, and the other is using a custom join.

Joins can be done as follows , substitute your tables instead of mine

Suppose here my table , controller is CourseLessonsReference Controller , so I can join other 2 or many tables as follows:

$conditionForId = array('CourseLessonsReference.course_id'=>$package_id,
    );  


    //Pagination logic
    $this->paginate = $allConditionsFields = array('conditions' => $conditionSearchLessonsByCourse,                                                                                                 
                            "joins" => array(
                                            array(//UserCourse = Course Join
                                                "table" => "courses",
                                                "alias" => "Course1",
                                                "type" => "INNER",
                                                "conditions" => array(
                                                    "Course1.id = CourseLessonsReference.course_id"
                                                )
                                            ),//For Category = Course Join
                                            array(
                                                "table" => "course_categories",
                                                "alias" => "CourseCategory",
                                                "type" => "INNER",
                                                "conditions" => array(
                                                    "CourseCategory.id = Course1.course_category_id"
                                                )
                                            )
                                        ),
                            'recursive' =>  2                               
                            );


 $resultOfJoin = $this->CourseLessonsReference->find('all', $allConditionsFields);

$resultOfJoin will give you result for Joins of 3 tables.

It means join Current table CourseLessonsReference with specified tables in Join tag in $allConditionsFields array .

As you didnt provide schema of your tables , Here in my case , Current Controller/model/table is CourseLessonsReference which will have references. References are associated with Course so course_id is foreign key in course_lessons_reference table . So this is 1 join. Now Course is connected to Category so , course will have course_category_id as foreign key.
