我有一个隐蔽的参数,即应穿透一个价值载荷的行为,但必须把纽伦放在外。
The problem is when pressing on the F5 (refresh) button after pressing the submit button because the url already contain &act=save so prssing on F5 actually pass (to cgi) the save value again (and it perform the save action again even I didn t press on the submit button.
The queston is how can I prevent sending the &act=save on pressing the reffresh button?
增 编
增 编 you all but the submit button is a save button - means I wish to leave the user the abbility to perfrom addiitonal save so don t wany to leave the page. From this reason, I don t think that the session may help to distinguish between the second save or the first refresh.
