Hi, I would appreciate help on the following.
I have been looking up ways to implement a cancel button with php. Basically, I have a mypictures.php file. There are select statements, grep statements, and a call to executables. I don't understand why there isn't that much around about this cancel topic? Have I been looking in the right places? The cancel button can be used if the user does not want to wait a long time for a big request and wait for the pictures to render. Also, I have had problems with the executables tying up the server. They can use the big stop button at the top of the Internet Explorer I think but I would like to make it user friendly and have the option to cancel in the php application itself. I want the cancel button to also direct the user to a page ready for a new search. Can I use posix_get pid and then posix_kill to kill the current instance of mypictures.php. Will this work? I'm not sure how to kill the executables started by this particular mypictures.php. Other people can open another session and I don't want to kill their mypictures.php or executables that they started. What is the difference between posix_getpid() and getmypid()? Are they the same thing? For the cancel button I was thinking of using a popup window or just use the mypictures.php that the top header part of the mypictures.php that is rendering and use an XML HTTP Request object to be able to cancel without sending another request. Are these ideas practical and possible? thanks! --------------------------------- Post your free ad now! Yahoo! Canada Personals
