OpenCart将表单添加到管理页面

Question

opencart 1.5.6

尝试在管理员端添加一个页面，以将图像上传到新文件夹（供网站的其他部分使用）

我有一个问题，就是从表单上载图像后，页面被重定向到了管理主页。 我试图通过在表单响应中重新呈现当前页面来解决此问题，但是现在我只加载了没有更新的页面版本，并且该功能似乎无法运行：

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说我正在实验）

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

        $this->language->load('common/hello');

                $template="common/hello.tpl"; // .tpl location and file

        $this->template = ''.$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(

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

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

  {
    if ($_FILES["file"]["error"] > 0)
  {

      }
else
  {

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


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

如我所说，我是新手，正在尝试使用此软件，以前从未使用过PHP MVC。 任何指针都将适用！

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();

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

模板：

<?php echo $footer; ?>

Answer 1

在您的控制器中，您应该构建OpenCart用于表单发布的所有标准方法，例如：

public function insert()

public function update()

public function getForm()

等等

看看admin/controller/catalog/attribute.php

您将看到一个名为insert()的公共方法，该方法通过$request对象捕获您的帖子数据，即： if (($this->request->server['REQUEST_METHOD'] == 'POST') && $this->validateForm()) {仅在满足条件时才执行内部的所有代码，然后该方法会将您转发到呈现此页面的$this->getForm() 。

我不确定您从何处获得示例代码，但它不正确，或者至少与正常的OpenCart标准不符。

使用其他文件中的现有代码作为新模块的基础。
