CCourse::GetCourseContent

CDBResult
CCourse::GetCourseContent(
 int COURSE_ID,
 array arAddSelectFileds = Array("DETAIL_TEXT", "DETAIL_TEXT_TYPE", "DETAIL_PICTURE")
);

The GetCourseContent method returns a list of active chapters and lessons sorted in the ascending order.

Remarks

• ID - the lesson or chapter ID;
• NAME - the lesson or chapter name;
• CHAPTER_ID - the parent chapter ID; 
• SORT - sort index;
• DEPTH_LEVEL - required nesting level; 
• TYPE - type of the required object ("LE" - lesson, "CH" - chapter).

To obtain other fields, use the arAddSelectFileds array. The method returns the course tree. If "DETAIL_TEXT", "DETAIL_TEXT_TYPE", "DETAIL_PICTURE" are not used, you are recommended to pass an empty arAddSelectFileds (arAddSelectFileds = Array()).

Parameters

arAddSelectFileds = 
    Array("DETAIL_TEXT", 
          "DETAIL_TEXT_TYPE", 
          "DETAIL_PICTURE")

Return Values

The method returns an instance of the CDBResult object.
