[thelist] possible jscript/php/frames question!!

What is the purpose of "encrypting" the co-ordinates? If it's to stop someone
between the client and the server from seeing and/or intercepting the data,
then we have something called "SSL" which is eminently suited to this task.

: i suspect that your thought regarding flash is probably the way to go...
: so,
: now i need a flash guru!!!
: if flash would take care of the mouse clicks/capturing the mouse clicks

: encrypting them prior to the coordinates being sent back to the server,
: this
: would solve the mouse/location issue...

: No. This is pretty basic HTML stuff.  The x/y bit is in the spec.  See

: Random shapes?  I don't recall you mentioning that earlier in the
: thread.  If you need to generate shapes on the fly, you'll need image
: generation, which is usually non-trivial.
: http://us2.php.net/manual/en/ref.image.php
: You might check out one of the image classes at phpclasses.org.  I
: believe there are a few classes to make generating shapes a simple

: If you're creating random images on the fly, and need the user to be
: able to click multiple points, and then take all that info and post it
: somewhere, you should probably go to Flash instead.  What you're
: decribing sounds a lot like a real basic Flash game (something like
: "shoot the woozle").  You could still collect the info and send it to a
: php script for processing.
: It would help to have some idea of what you're trying to accomplish.
: Can you give us some more info?
