在joomla模块中上传文件

Question

我已经搜索了很长一段时间但找不到符合我需要的解决方案.我正在为Joomla 2.5开发一个模块.我需要允许用户在模块配置中从后端上传图像/任何文件类型的功能.

问题:如何在joomla模块中添加文件上载字段.

谢谢!

Answer 1

只是来自joomla文档的示例:

<?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,您的HTML表单必须包含

enctype="multipart/form-data"

否则你不会得到joomla函数的任何结果!
