joomla模块中的文件上传

Question

我一直在寻找这个相当长的一段时间，但找不到解决方案来匹配我的需求。我正在为Joomla 2.5开发一个模块。我需要功能来允许用户在模块配置中从后端上载图像/任何文件类型。

问题：如何在joomla模块中添加文件上传字段。

谢谢！

Answer 1

刚从的Joomla文档样本：

<?php 

//Retrieve file details from uploaded file, sent from upload form 
$file = JRequest::getVar('file_upload', null, 'files', 'array'); 

//Import filesystem libraries. Perhaps not necessary, but does not hurt 
jimport('joomla.filesystem.file'); 

//Clean up filename to get rid of strange characters like spaces etc 
$filename = JFile::makeSafe($file['name']); 

//Set up the source and destination of the file 
$src = $file['tmp_name']; 
$dest = JPATH_COMPONENT . DS . "uploads" . DS . $filename; 

//First check if the file has the right extension, we need jpg only 
if (strtolower(JFile::getExt($filename)) == 'jpg') { 
    if (JFile::upload($src, $dest)) { 
     header("Location: http://".$_SERVER["HTTP_HOST"]."/administrator"); Redirect to a page of your choice 
    } else { 
    echo "error !"; //Redirect and throw an error message 
    } 
} else { 
    echo "Wrong extension !"; //Redirect and notify user file is not right extension 
} 

?>

请记住，你的HTML表单必须包括

enctype="multipart/form-data"

否则你不会得到任何结果的joomla功能！
