Submit a Pull Request Report a Bug. This post is with regards to handling forms that have more than one submit button. This works fine, except when we want to pass more information with the click of this particular button. Imagine a scenario where you're dealing with user management in some administrative interface. You are presented with a list of user names queried from a database and wish to add a "Delete" and "Modify" button next to each of the names in the list. Naturally the 'value' of our buttons in the HTML form that we want to display will be "Delete" and "Modify" since that's what we want to appear on the buttons' faceplates. In other words, the 'name' of the buttons along cannot carry any uniquely identifying information if we want to process them systematically after submit.

Many people do it the complicated way: setcookie 'name', 'content', time ; But why do you make it so complicated and risk it not working, when the client's time is wrong? Why fiddle around with time ; Here's the easiest way to unset a cookie: setcookie 'name', 'content', 1 ; Thats it.

Caveat: Symbolic links are pre-resolved, so don't trust comparison of paths to be accurate. Caveat: Symbolic links are not pre-resolved, use PHP's 'realpath' function if you need it resolved. Caveat: "Filename" makes you think it is just a filename, but it really is the full absolute pathname. Read the identifier as "Script's filesystem path name". No trailing slash.
