Question

当我更改此$ this-> load-> view（'profile'，['getPlacetype'=> $ getPlacetype]，$ custom_errors）时，我在做什么方面遇到麻烦。对此 $ this-> load-> view（'profile'，['getPlacetype'=> $ getPlacetype]，$ custom_errors）; 没有未定义的索引，但是选择数据将没有

profilecon

    public function index(){

    $this->load->model('Placetype');
    $getPlacetype = $this->Placetype->getPlacetype();


    if (!isset($_SESSION['username']) || empty($_SESSION['username'])) {
        header("Location: ".base_url()."index.php/login_con/login");
        die();

    }
    $custom_errors["nadate"] = false;
    if (isset($_POST['profile'])) {
        $this->form_validation->set_rules('mobilenum', 'Mobile Number', 
     'required');
        $this->form_validation->set_rules('homeadd', 'Home Address', 
     'required');
        $this->form_validation->set_rules('startdate', 'Start Date', 
     'required');
        $this->form_validation->set_rules('enddate', 'End Date', 
     'required');

        $custom_errors["nadate"] = ($this->verifydate($_POST["startdate"], 
      $_POST["enddate"]) < 3 ? false : true);


        //if form validation true
         if($this->form_validation->run() == TRUE && $this- 
        >verifydate($_POST["startdate"], $_POST["enddate"]) < 3) {
        $data = array(
                'username' => $this->session->userdata("username"),
                'mobilenum' => $_POST['mobilenum'],
                'homeadd' => $_POST['homeadd'],
                'startdate' => $_POST['startdate'],
                'enddate' => $_POST['enddate'],
            );

            $_SESSION["profile_data"] = $data;
            redirect("shopping_cart","refresh");
          }

          }

        $this->load->view('profile',     
        ['getPlacetype'=>$getPlacetype],$custom_errors );

向视图发送大量数据并不难。要了解的是如何使用发送到视图的数组。简而言之，数组中的每个key都是视图中variable的名称。该数组必须是关联数组。

请记住

//this line
$getPlacetype = $this->Placetype->getPlacetype();
// should be changed to this
$view_data['getPlacetype'] = $this->Placetype->getPlacetype();

然后

$custom_errors["nadate"] = ($this->verifydate($_POST["startdate"],
// changed to
$nadate = ($this->verifydate($_POST["startdate"],
                        $_POST["enddate"]) < 3 ? false : true);

您可以删除该行

$custom_errors["nadate"] = false;

更改此

if($this->form_validation->run() == TRUE && 
   $this->verifydate($_POST["startdate"], $_POST["enddate"]) < 3) {

到

if($nadate === TRUE && $this->form_validation->run() === TRUE) {

如果未执行上述代码，则创建一条错误消息并加载视图

$view_data['custom_errors'] = "Start and End dates were wrong";
$this->load->view('profile', $view_data);

视图的相关部分可以这样完成。

<div class="form-group">
    <label for="place_type">City/Province</label>
    <select name="place_type">
        <option value="place_type">-Please Select One-</option>
        <?php
        if(count($getPlacetype)) :
            foreach ($getPlacetype as $getplacetype):
                ?>
                <option value=<?php echo $getplacetype->place_id; ?>>
                    <?php
                    echo $getplacetype->place_type;
                    echo $getplacetype->place_price;
                    ?>
                <span> PHP Shipping Fee</span>
                </option>

                <?php
            endforeach;
            else:
               echo isset($custom_errors) ? $custom_errors : NULL;
            endif;
            ?>
    </select>
</div>

希望这演示了如何做您想做的事。

尝试一下：将数组定义为空白。

   public function index(){
  $data = array();

///在这里您可以使用$ data和firstArray之类的内容，您可以在视图页面中传递。

$data['firstArray']=get data;
$data['secondArray']=get data;
 $this->load->view(''profile', $data);
}
