hi richard , thanks for ur response. as from your suggestion i try to solve my problem like following this instruction-
( A simpler solution maybe to set the users' home page to their /my page - which will give them a list of the courses they are already on (Site Administration > Appearance > Navigation > Default Home Page for Users = My Home). Clicking the course title will take them to that course and clicking Turn Edit On will allow them to edit the content of the course.)
but i m not able to solve my need.please do u have any solution for this cause i m not trying to create a new plugin but want to do the work which is possible to solve inside moodle.
waiting for ur response.
