The checkbox only has one value, which you set in its value="" attribute. If the checkbox is not checked, then it does not send a value on form submit. It only sends this value when it is checked.
yeah, if checked it sends 1, if not checked nothing, on the DB field I have degault set to 0, so if not checked on the front end the DB will insert 0 and on front end if checkbox is ticked it sends 1.
and the dynamic attribute is set to Checked SC_ViewClientDetails.data.ViewClientDetails.Users_Data[0].OnWhatsapp
the checkbox works in terms of showing its checked on selecting from teh DB, but it does not do an update or insert, only if i go directly into the DB and set it to 1 it shows as ticked, if i then untick it, nothing changes on the db, equally if its unticked and i tick it nothing it sent to the server end
