单击按钮

Question

这是我的路线：

  'router' => array(
    'routes' => array(
         'upload' => array(
            'type' => 'segment',
            'options' => array(
                'route'    => '/products/upload[/:products]',
                'defaults' => array(
                    'controller' => 'Products\Controller\Upload',
                    'action'     => 'index'
                ),
            ),
            'may_terminate' => true,
            'child_routes' => array(
                'uploadsuccessful' => array(
                    'type' => 'literal',
                    'options' => array(
                        'route'    => '/uploadsuccessful',
                        'defaults' => array(
                            'controller' => 'Products\Controller\Upload',
                            'action'     => 'successful'
                        ),
                    ),
                ),
            ),    
        ),
    ),
);

我试图从不同的视图脚本中多次调用此路由，从而提供不同的[/:products]参数。

<a href="<?php echo $this->url('upload', array('products' =>'shoes')); ?>">Upload Shoes Product Image</a>
<a href="<?php echo $this->url('upload', array('products' =>'trainers')); ?>">Upload Trainers Product Image</a>
<a href="<?php echo $this->url('upload', array('products' =>'hats')); ?>">Upload Hat Product Image</a>

这是我的控制器代码。

 <?php

namespace Products\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Products\Form\UploadForm;

class UploadController extends AbstractActionController
{
    protected $_dir = null;

    public function indexAction()
    {   
        $products = $this->params()->fromRoute('products');

        $config = $this->getServiceLocator()->get('Config');
        $fileManagerDir =$config['file_manager']['dir'];

        $this->_dir = realpath($fileManagerDir) . 
            DIRECTORY_SEPARATOR .
            $products; 


        if (!is_dir($this->_dir)) {
            //read, write, execute
            mkdir($this->_dir, 0777);
        }

        $form = new UploadForm($this->_dir, 'upload-form');
        $request = $this->getRequest();

        if ($request->isPost()) {
            $post = array_merge_recursive(
                $request->getPost()->toArray(),
                $request->getFiles()->toArray()
            );

            $form->setData($post);

            if ($form->isValid()) {
                $data = $form->getData();

                $this->setFileNames($data);
                return $this->redirect()->toRoute('upload/uploadsuccessful', array('products' =>$products));
            }
        }
        return new ViewModel(array('form' => $form));
    }

    public function successfulAction()
    {
        $file = array();
        $flashMessenger = $this->flashMessenger();
        if ($flashMessenger->hasMessages()) {
            foreach($flashMessenger->getMessages() as $key => $value) {  
                $file = $value;    
            }
        }
        return new ViewModel(array('file' => $file));
    }

    protected function setFileNames($data)
    {
        unset($data['submit']);
        foreach ($data['image-file'] as $key => $file) {
            rename($file['tmp_name'], $this->_dir . DIRECTORY_SEPARATOR . $file['name']);
        }       
    }
}

我认为这个想法很明确：对于每个[/:products]参数，我尝试在$fileManagerDir中创建具有给定名称的单独文件夹。

但是，有一个问题。当我点击按钮上传($request->isPost() == true)参数$products变为null时，上传的文件就不会转到相应的文件夹。此外，我无法重定向到成功的操作 - 错误出现＆＃34;缺少参数＆＃34;因为$ products为null。

在您的视图脚本中，上传按钮是href链接。这将导致GET REQUEST被发送到控制器而不是POST，也不会出现FILES。除非是这样，否则你正在用外部JS拦截click事件，你在这里没有提到。路径网址应位于表单操作属性中。提交按钮应该是按钮而不是链接（除非您使用的是JS，此处未提及）。确保将表单方法设置为POST。

类似的东西：

<form action="<?php echo $this->url('upload', array('products' =>'shoes')); ?>" method="post" enctype="multipart/form-data">

您需要使用JS处理动态操作或重新设计路由。
