conditional delete

vinod_ccv

$_POST['action']=='delete' i want to make a check so that if the $_POST['id'] item is used in another subcategory table. If so i have to stop execution and show the message. Where to incorporate this test in php side?

Just before you call the `process` method on the Editor instance I'd say. Or anywhere before you initialise the Editor instance would do as well.

Thank you Allan,
But how to get the custom error message to client?

Respond with an `error` parameter set: http://editor.datatables.net/server/#error

i would like to customize this Global form error and appear on top of data table window

Well the `error` is the global error so you could use that - but it shows at the bottom of the modal. To show it at the top you would need to create a custom display controller.
