杂货杂货过滤问题

Question

I want to know how to filter the retrieval of the records in my table. I am using grocery_crud on top of codeigniter. I don't know how to put a condition on the results that are retrieved. For example,i have a customers crud and i want to retrieve only the ones in new york. Please help

this is my function and i want to narrow the results before rendering the view

    public function employees(){
        $crud = new grocery_CRUD();
        $crud->set_subject('employees');
        $crud->set_table('employees');
        $crud->columns('firstName','email');
        $crud->display_as('firstName','first name');
        $crud->display_as('email','e-mail address');
        $crud->required_fields('email');
        $output = $crud->render();

        $this->output($output);
    }

Answer 1

You would use the where function:

$crud->where('city','New York');

There are a lot of nifty functions available !
