Magento利用input type=”file”上传图片

首先在模板文件加个表单,内容如下：

<form action=”<?php echo $this->getUploadFile();?>” method=”post” enctype=”multipart/form-data”>
<input type=”file” name=”upload_file”><br/>
<input type=”submit” name=”submitForm”>
</form>

然后，就是在控制器处理图片上传了，代码如下：

$uploader = new Varien_File_Uploader(array(‘tmp_name’=>$_FILES['upload_file']['tmp_name'],’name’=>$_FILES['upload_file']['name']));

//设置允许上传的图片格式
$uploader->setAllowedExtensions(array(‘jpg’,’jpeg’,’gif’,’png’));
$uploader->addValidateCallback(‘catalog_product_image’, Mage::helper(‘catalog/image’), ‘validateUploadFile’);
$uploader->setAllowRenameFiles(true);
$uploader->setFilesDispersion(true);
$result = $uploader->save(Mage::getSingleton(‘catalog/product_media_config’)->getBaseTmpMediaPath());

$imageTmp = $result['file'] . ‘.tmp’;

$mediaModel=Mage::getModel(‘catalog/product_attribute_backend_media’);
//最终保存到数据库的路径

$imageUrl= $mediaModel->_moveImageFromTmp($imageTmp);

最后就是显示图片了，内容如下：

$imageSrc=Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_MEDIA).’catalog/product’.$imageUrl;

<img src=”<?php echo $imageSrc;?>”>
