Hi I have a form and buttons insert, update, delete with input boxes. Method is post , action $PHP_SELF (php 4.0.6+MSSQL) When user presses insert button then i have action=$PHP_SELF&operation=insert&name=SomeName&lname= &SomeLName&... After submit it all goes well and data are inserted into the table. But when i am testing this page and click refresh i guess that same date will be inserted one more time, or updated or deleted depending on the opeartion. How can i prevent this ?
