Question

我自定义了一个参数来添加按钮上传<input type="file" name="file">

时如何上传

您需要调整一些内容才能使上传工作。

将表单的enctype更改为enctype="multipart/form-data"
如果使用MVC架构，请在表单中添加task和controller。

上传文件非常简单，因为Joomla有filesystem个包。您上传文件所需的只是致电JFile::upload($src, $dest)。

阅读文件系统包，你会发现很多有用的东西。这是链接http://docs.joomla.org/How_to_use_the_filesystem_package

以下是上传代码的内容（来自Joomla文档）

/**
 * Uploading function for Joomla
 * @param int $max maximum allowed site of file
 * @param string $module_dir path to where to upload file
 * @param string $file_type allowed file type
 * @return string response message
 */    
function fileUpload($max, $module_dir, $file_type){
        //Retrieve file details from uploaded file, sent from upload form
        $file = JRequest::getVar('file_upload', null, 'files', 'array'); 
        // Retorna: Array ( [name] => mod_simpleupload_1.2.1.zip [type] => application/zip 
        // [tmp_name] => /tmp/phpo3VG9F [error] => 0 [size] => 4463 ) 

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

                if($file['size'] > $max) $msg = JText::_('ONLY_FILES_UNDER').' '.$max;
                //Set up the source and destination of the file

                $src = $file['tmp_name'];
                $dest = $module_dir . DS . $filename;

                //First check if the file has the right extension, we need jpg only
                if ($file['type'] == $file_type || $file_type == '*') { 
                   if ( JFile::upload($src, $dest) ) {

                       //Redirect to a page of your choice
                        $msg = JText::_('FILE_SAVE_AS').' '.$dest;
                   } else {
                          //Redirect and throw an error message
                        $msg = JText::_('ERROR_IN_UPLOAD');
                   }
                } else {
                   //Redirect and notify user file is not right extension
                        $msg = JText::_('FILE_TYPE_INVALID');
                }

        }
        return $msg;
}
