I am developing the admin panel for my web application. On the index of the member management section is a list of the newest member accounts. There is a checkbox for each member that an admin can check to delete multiple users at once. I use jQuery to submit the form with a link. Since the form is on the index of the member management section(members/home), I want the process of the form to be on members/delete. When the members/delete controller is accessed, there is an option of providing a single member ID in a URL segment or the admin can use the form on the members index page.
My problem is that none of the data from the checkboxes is being passed to the members/delete controller. I have tried $this->input->post('delete_members') and $_POST['delete_members']. I have also tried changing the method of the form to GET and then $_GET['delete_members']. I get "Undefined index: delete_members with everything I try. Any ideas?
PS: I have a route that changes members/delete to members/home/delete
Members controller: (members/home)
