Hi,
I would appreciate help with the following. I am trying to implement a cancel
button on in a php application. In this application a person can login to his
/her account and access a database.
The PHP file that I am working on contains some input boxes and some pull down
lists. According to the user's input and some choices the mypictures.php
will
1) make select statements from the database (I am using MySQL)
2) in a loop has a grep statement that looks for pictures stored in the
database
3) call an excutable file called generatepicture and generatepicture also calls
another excutable gatherparts
A cancel button will be useful when a user makes a big request and then decides
to cancel.
This is a php and linux question as inside my php file there is a loop and
inside the look there is a call "system" call that executes a shell script item
#3 listed above. Inside this shell script there are serveral calls to execute
executables from a third party software
One problem I have is that the php file is rendering itself so I'm not sure
where or if the cancel can be placed or if it will be functional on the
mypictures.php page. Let us say I have solved this problem with a pop up window
that contains the cancel button.
My next linux related problem is that I want to stop the mypictures.php page
itself and I want to stop any exectuables is has started.
I plan on having the cancel button redirecting the user to a fresh new page but
before redirecting I would like to stop the three processes that I mentionned
ie. select statements, grep statement and most importantly the executables that
get called in the background.
I have had problems with the server getting tied up because some of the
executables kept on running.
How do I stop these processes? Should I or could I use the kill command
if so how would I find the process ID of the original mypictures.php and any of
the executables it has called.
Thanks!
