problem with sending data

Dear I have problem with writing large data (large text) in the database or any file . If we try to do, the field in the DB or the file will be empty . (We lose the data) . I mean by large data more them 60 Kbyte . But if we try to write small text (less then 60K) , the text will be added normally in the DB or in the files . Knowing that all settings are good : max_allowed_packet=10M ; Maximum size of POST data that PHP will accept. post_max_size = 8M And the DB accept large text normally . Do you have any Idea how we can solve this problem ? Or is there any setting i must change it ? If you can help me Waiting your answers ASAP Thanks MOSES Feb. 8 , 2009
