zhq Posted October 3, 2006 Share Posted October 3, 2006 Dear All,The database I used is MySQL. I am trying to block user from downloading files to local temp directory while viewing a confidential document online. I don't know how to do it. Any help will be much appreciated. Thanks a lot in advance.zhq Quote Link to comment Share on other sites More sharing options...
ToonMariner Posted October 3, 2006 Share Posted October 3, 2006 NOt bang up on this but if you use this header...header('Cache-Control: no-cache');that will prevent the browser automatically cahcing the file - then you will need some magic to prevent the user saving the file - javascipt unfortunately so they could disable it. In that case use javascript to construct the page - that way they need it on to see it so you can then control them saving... Quote Link to comment Share on other sites More sharing options...

zhq Posted October 6, 2006 Author Share Posted October 6, 2006 Dear All,Sorry I am not quite clear about this becasue I am new to all the topic. Using "header('Cache-Control: no-cache')", the downloading to the temp directory can be blockbed. For blocking user to use the 'save as' function to save a PDF file, the java script has to be used. Am I right? Instead of using Java script, can PHP script work for this?I need a clear drection so that I know how to start my work. Thanks.zhq Quote Link to comment Share on other sites More sharing options...
