im trying to update my data using a checkbox. It needs to change the value "active" from 0 to 1" when the checkbox has been clicked.
That means that the content should be gone until later when you return it it becomes in store again. (delete but without real delete).
There's some screenshots from my databases in mysql and also the php code below:
Would really appreciate some help.
Thanks
