magento 如何上传file/image/video

首先创建模块所需要的所有文件夹。
在/app/code/local/Company/ModName/Block/Adminhtml/ModName/Edit/Form.php添加‘enctype’ => ‘multipart/form-data’
这样才能够使用$_FILES 获取值。

code如下：

$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/app/code/local/Company/ModName/Block/Adminhtml/ModName/Edit/Tab/Form.php里，
_prepareForm中，上传文件类型有3种，file,image,imagefile;image类型能预览和删除图片。
code如下：

$fieldset->addField(‘fileinputname’, ‘file/image/imagefile’, array(
‘label’     => Mage::helper(‘pictos’)->__(‘File label’),
‘required’  => false,
‘name’      => ‘fileinputname’,
));

在/app/code/local/Company/ModName/controllers/Adminhtml/ModuleNameController.php 里saveAction，
if ($data = $this→getRequest()→getPost())下面添加如下code：

if(isset($_FILES['fileinputname']['name']) and (file_exists($_FILES['fileinputname']['tmp_name']))) {
try {
$uploader = new Varien_File_Uploader(‘fileinputname’);
$uploader->setAllowedExtensions(array(‘jpg’,'jpeg’,'gif’,'png’)); // or pdf or anything

$uploader->setAllowRenameFiles(false);

// setAllowRenameFiles(true) -> move your file in a folder the magento way
// setAllowRenameFiles(true) -> move your file directly in the $path folder
$uploader->setFilesDispersion(false);

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

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

$data['fileinputname'] = $_FILES['fileinputname']['name'];
}catch(Exception $e) {

}
}

如果你的上传类型是image，请使用如下code来删除图片：

else {

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