控制器

public function search_keyword() {
    $keyword = $this->input->post('keyword');
    $data['zipcode_serching_results'] = $this->Provider_Profile_Model->search($keyword);
    $data['searching_data'] = $keyword;

    $userid = $this->session->userdata('uid');
    $data['profile'] = $this->Provider_Profile_Model->getprofile($userid);
    $this->load->view('provider/dashboard', $data);
}

模型

public function search($keyword) {
  $this->db->like('zipcode', $keyword);
  $query = $this->db->get('tblfamily')->result();
  return $query;
}

推荐答案

首先，您必须在表单中添加带有表选项的select标记

First you have to add select tag with table options to your form

<select id="tables" name="tables" form="ID-OF-YOUR-FORM-HERE">
  <option value="tblcaregiver">tblcaregiver</option>
  <option value="tblfamily">tblfamily</option>
  <option value="mercedes">Mercedes</option>
  <option value="tblprovider">tblprovider</option>
</select>

接下来，您必须在控制器中获取选择的数据，并将其传递给模型

Next, you have to fetch the select data in your controller, and pass it on to your model

public function search_keyword() {
    $keyword = $this->input->post('keyword');
    // fetch selected table 
    $table = $this->input->post('tables');
    $data['zipcode_serching_results'] = $this->Provider_Profile_Model->search($keyword, $table); // 2nd parametar added
    $data['searching_data'] = $keyword;

    $userid = $this->session->userdata('uid');
    $data['profile'] = $this->Provider_Profile_Model->getprofile($userid);
    $this->load->view('provider/dashboard', $data);
}

最后，更新您的模型，并动态选择表格

Finally, update your model, and dynamically select table

public function search($keyword, $table) {
  $this->db->like('zipcode', $keyword);
  $query = $this->db->get($table)->result();
  return $query;
}
