打开购物车 1.5.6

尝试在管理端添加一个页面以将图像上传到新文件夹（用于站点的其他部分）

我有一个问题，从表单上传图像后，页面重定向到管理主页。我试图通过在表单响应中重新呈现当前页面来解决这个问题，但现在我只是加载了一个没有更新的页面版本，并且该函数似乎没有运行：

模板文件：（hello.tpl）

<?php echo $header; ?>
<div id="content">
  <div class="breadcrumb">
    <?php foreach ($breadcrumbs as $breadcrumb) { ?>
    <?php echo $breadcrumb['separator']; ?><a href="<?php echo $breadcrumb['href']; ?>"><?php echo $breadcrumb['text']; ?></a>
    <?php } ?>
  </div>

<form action="index.php?route=common/helloworld&token=<?php echo $token; ?>"     method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>

<?php
if ($error > 0)
{
echo $error;
}
elseif ($error1 > 0)
{
echo $error;
}
elseif ($error2 > 0)
{
echo $error;
}
elseif ($up > 0)
{
echo $up;
echo $type;
echo $size;
echo $store;
echo $store2;
}
else
{
echo "Upload File";
}

?>
</div> 
<?php echo $footer; ?>

控制器文件（hellowworld.php - 我知道：PI DID 说我正在试验）

<?php
class ControllerCommonHelloworld extends Controller { 
    public function index(){
                // VARS

}
?>

正如我所说，我是新手，正在试验这个软件，以前从未使用过 PHP MVC。任何指针都会被应用！

解决了：

控制器：

<?php
class ControllerCommonHelloworld extends Controller { 
    public function index(){
                     .................

    public function image() {

        $this->language->load('common/hello');
        $template="common/hello.tpl"; // .tpl location and file
        $this->load->model('common/hello');
        $this->template = ''.$template.'';
        $this->children = array(
            'common/header',
            'common/footer'
        );      

        $this->data['token'] = $this->session->data['token'];

        $this->data['breadcrumbs'] = array();

        $this->data['breadcrumbs'][] = array(
            'text'      => $this->language->get('text_home'),
            'href'      => $this->url->link('common/home', 'token=' . $this->session->data['token'], 'SSL'),
            'separator' => false
        );

        $this->data['breadcrumbs'][] = array(
            'text'      => $this->language->get('heading_title'),
            'href'      => $this->url->link('common/helloworld', 'token=' . $this->session->data['token'], 'SSL'),
            'separator' => ' :: '
        );

$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")

|| ($_FILES["file"]["type"] == "image/png"))
&& ($_FILES["file"]["size"] < 200000)
&& in_array($extension, $allowedExts))
  {
    if ($_FILES["file"]["error"] > 0)
  {
  $this->data['error'] = "Error: " . $_FILES["file"]["error"] . "<br>";
  }
else
  {
  $this->data['up'] = "Upload: " . $_FILES["file"]["name"] . "<br>";
  $this->data['type'] = "Type: " . $_FILES["file"]["type"] . "<br>";
  $this->data['size'] = "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
  $this->data['store'] = "Stored in: " . $_FILES["file"]["tmp_name"];

  if (file_exists("/image/TEST/" . $_FILES["file"]["name"]))
      {
      $this->data['error1'] = $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "/image/TEST/" . $_FILES["file"]["name"]);
      $this->data['store2'] = "Moved To: " . "image/TEST/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  $this->data['error2'] = "Invalid file";
  }


    $this->response->setOutput($this->render());
 }
}
?>

模板：

<?php echo $header; ?>
<div id="content">
  <div class="breadcrumb">
    <?php foreach ($breadcrumbs as $breadcrumb) { ?>
    <?php echo $breadcrumb['separator']; ?><a href="<?php echo $breadcrumb['href']; ?>"><?php echo $breadcrumb['text']; ?></a>
    <?php } ?>
  </div>

<form action="index.php?route=common/helloworld/image&token=<?php echo $token; ?>" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>

<?php
if (isset($error))
{
echo $error;
}

if (isset($error1))
{
echo $error1;
}

if (isset($error2))
{
echo $error2;
}

if (isset($up))
{
echo $up;
echo $type;
echo $size;
echo $store;
echo $store2;
}

if (!isset($error) and !isset($error1) and !isset($error2) and !isset($up))
{
echo "Upload File";
}

?>
</div> 
<?php echo $footer; ?>

在您的控制器中，您应该构建 OpenCart 用于表单帖子的所有标准方法，例如：

public function insert()

public function update()

public function getForm()

等等

看一眼admin/controller/catalog/attribute.php

您会看到有一个名为的公共方法insert()，它通过$request对象捕获您的帖子数据，即：if (($this->request->server['REQUEST_METHOD'] == 'POST') && $this->validateForm()) {只有在满足条件时才会执行内部的所有代码，然后该方法将您转发到$this->getForm()呈现页面的位置。

我不确定你从哪里得到你开始的示例代码，但它不正确，或者至少不符合正常的 OpenCart 标准。

使用不同文件中的现有代码作为新模块的基础。
