     return false; 
    } else { 
     $('.first_name').hide();

請幫我....

變化，這在您添加AJAX單引號（'）

data:{ 
        'first_name' : first_name ,'last_name' : last_name ,'dob' : dob , etc... 
       }, 

在CONTROLER成員

function register(){ 
     $add_user = array(
        'mem_name'=> $this->input->post('first_name'), 
        'mem_lastname'=> $this->input->post('last_name'), 
        'mem_dob'=> $this->input->post('dob'), 
        'mem_gender'=> $this->input->post('gender'), 
        'mem_email'=> $this->input->post('email_id'), 
        'mem_address'=> $this->input->post('address'), 
        'mem_zipcode'=> $this->input->post('zipcode'), 
        'mem_phone'=> $this->input->post('phone'), 
        'mem_password'=> $this->input->post('password'), 
    ); 
     $this->member_model->add_user($add_user); 
    } 

在member_model

function add_user($add_user){ 
    $insert = $this->db->insert('membership', $add_user); 
}
