checkbox on the detail page
Design and Skin Customization
your asking me to build it, then tell you how I did it?
There are many ways to do it. The way that first jumps to mind is to put a jquery event onto the checkbox eg:
http://stackoverflow.com/questions/6017558/checkbox-checked-or-unchecked-with-jquery-and-mysql
Then post that to a processor in a module:
your-site/checkboxchecker/update
then build a module called:
bmCheckboxchecker
That controls the url 'checkboxchecker'.
When the checkbox is checked that url will be called via ajax and you can do whatever processing you need to do.
Return the result via json_encode() to update the page visually.
Its a little bit fiddly but totally doable.
The standard way would be for the user to open the jrFile form and check the checkbox then click update.
