Question

我需要为Magento Blog Module（AW博客）中的帖子创建图片上传字段。因此，每个帖子都需要包含一个图像。

我编辑了以下文件： /home/clients/websites/w_gale/public_html/gale/app/code/community/AW/Blog/Block/Manage/Blog/Edit/Tab/Form.php

添加了这样的字段集：

$fieldset->addField('fileinputname', 'image', array(
            'label'     => Mage::helper('blog')->__('Upload image'),
            'required'  => false,
            'name'      => 'fileinputname',
            'required'  => true,
            'style'     => 'height:100px;border:2px solid #999;',
    ));

在这个文件的顶部，在正确的位置，我定义了这样的形式：

$form = new Varien_Data_Form(array(
            'id' => 'edit_form',
            'action' => $this->getUrl('*/*/save', array('id' => $this->getRequest()->getParam('id'))),
            'method' => 'post',
            'enctype' => 'multipart/form-data',
       )
    );

在Blogcontroller.php中，我添加了以下代码，只是在if ($data = $this->getRequest()->getPost()) {行后面

if(isset($_FILES['fileinputname']['name']) && (file_exists($_FILES['fileinputname']['tmp_name']))) {
            try {

                $uploader = new Varien_File_Uploader('fileinputname');

                $uploader->setAllowedExtensions(array('jpg','jpeg','gif','png')); // or pdf or anything

                $uploader->setAllowRenameFiles(true);
                $uploader->setFilesDispersion(false);

                $path = Mage::getBaseDir('media') . DS ;

                $uploader->save($path, $_FILES['fileinputname']['name']);

                $data['imageurl'] = $_FILES['fileinputname']['name'];

            } catch(Exception $e) {

            }
        } else {       

            if(isset($data['fileinputname']['delete']) && $data['fileinputname']['delete'] == 1)
                $data['imageurl'] = '';
            else
                unset($data['fileinputname']);
        }

但是，上传不起作用。我究竟做错了什么？我在数据库的相应字段中添加了一个特殊行。我手动输入时，前端部分显示数据库值。

这个上传图片的数据助手的方法代码。您需要实现方法getBaseDir()（它可以在您希望存储上传文件的位置返回目录）。

/**
 * Upload image and return uploaded image file name or false
 *
 * @throws Mage_Core_Exception
 * @param string $scope the request key for file
 * @return bool|string
 */
public function uploadImage($scope)
{
    $adapter  = new Zend_File_Transfer_Adapter_Http();
    $adapter->addValidator('ImageSize', true, $this->_imageSize);
    $adapter->addValidator('Size', true, $this->_maxFileSize);
    if ($adapter->isUploaded($scope)) {
        // validate image
        if (!$adapter->isValid($scope)) {
            Mage::throwException(Mage::helper('mycompany_mymodule')->__('Uploaded image is not valid'));
        }
        $upload = new Varien_File_Uploader($scope);
        $upload->setAllowCreateFolders(true);
        $upload->setAllowedExtensions(array('jpg', 'gif', 'png'));
        $upload->setAllowRenameFiles(true);
        $upload->setFilesDispersion(false);
        if ($upload->save($this->getBaseDir())) {
            return $upload->getUploadedFileName();
        }
    }
    return false;
}

您正在使用正确的代码。我通过使用正确的MYSQL数据类型解决了这个问题。当我将数据类型从'text'更改为'varchar（255）'时，它解决了问题

并确保添加以下代码：

$form = new Varien_Data_Form(array(
        'id' => 'edit_form',
        'action' => $this->getUrl('*/*/save', array('id' => $this->getRequest()->getParam('id'))),
        'method' => 'post',
        'enctype' => 'multipart/form-data',
   )
);
