[SOLVED] How to save X,Y Coords with this script

[jaku78]

I'll be honest, I'm not that great with java, and I'm only wondering about this script so I can use it with PHP and My SQL.

 

I found this scipt from a linked website and I'm wondering, do you think its possible to make it save the coords of items in them?

What I'm trying to do with this I Frame Dragable script is make it possible for graphics to be dragged in a image, and save the coordinates of the dragable image in a SQL server file. If someone has a better idea on how I can do this... Just tell me right now, because this is getting quite confusing for a guy that only knows HTML and PHP.

[nogray]

That's a long script to read

 

You can use the drag and drop script in the NoGray javascript library or Yahoo UI library if you want something to run after the object is finished being draged.

 

When the dragging is over, retrive the x and y value using Javascript (the above libraries have built in values) and pass those values to php (either using ajax or iframes)

 

This should save the x and y coord
