我正在设计CI应用程序并陷入ajax查询。基本上我写的函数是当按下保存按钮时将id作为null，即使我点击编辑按钮它显示它拾取正确的id。看起来我在功能上有一些错误。以下是我写的功能：
public function ajax_update()
{
$this->_validate();
$data = array(
//'firstName' => $this->input->post('firstName'),
//'lastName' => $this->input->post('lastName'),
//'gender' => $this->input->post('gender'),
//'address' => $this->input->post('address'),
//'dob' => $this->input->post('dob'),
//'tid' => $this->input->post('tid'),
'name' => $this->input->post('tname'),
);
$this->transport->update(array('tid' => $this->input->post('tid')), $data);
var_dump( $this->input->post());
echo json_encode(array("status" => TRUE));
}
更新功能是
public function update($where, $data)
{
$this->db->update($this->table, $data, $where);
return $this->db->affected_rows();
}
