unset_list

void unset_list()

Quick Description: Unset the first page list (datagrid)

This functionality simply unset the list (datagrid). So the user is not able to access the list page.

Example:

function unset_list_example()
{
    $crud = new grocery_CRUD();
 
    $crud->set_theme('datatables');
    $crud->set_table('employees');
    $crud->set_relation('officeCode','offices','city');
    $crud->display_as('officeCode','Office City');
    $crud->set_subject('Employee');
 
    $crud->unset_list();
 
    $output = $crud->render();
    $this->_example_output($output);
}

Notice: When a user land to the first list webapge then an unhandle exception with message "You don't have permissions for this operation".

We didn't want to add a show_error there because then you cannot handle the exception. So a quick way to have a default Codeigniter error message is:

try{
    $crud->render();
} catch(Exception $e) {
    show_error($e->getMessage());
}

or if you want to do it with the right way and have a message for the user you can do it like this:

try{
    $crud->render();
} catch(Exception $e) {
   if($e->getCode() == 14) //The 14 is the code of the "You don't have permissions" error on grocery CRUD.
   {
        $this->load->view('permission_denied.php');//This is a custom view that you have to create
        //Or you can simply have an error message for this
        //For example: show_error('You don\'t have permissions for this operation');
   }
   else
   {
    show_error($e->getMessage());
   }
}

And if you want the user to have for example the add form you can easily copy the url of the add form for example: localhost/your_project/index.php/examples/test/add and simply direct him there. Or you can also do this:

try{
    $crud->render();
} catch(Exception $e) {
 
    if($e->getCode() == 14) //The 14 is the code of the "You don't have permissions" error on grocery CRUD.
    {
        redirect(strtolower(__CLASS__).'/'.strtolower(__FUNCTION__).'/add');
    }
    else
    {
        show_error($e->getMessage());
    }
}

You have the freedom to do whatever you like rather than have it into the core library.
