解决opengoo下载中文文件名乱码问题

发现是IE浏览器对于UTF-8的支持不太好要把下载文件名转换成GBK编码。

 

需要修改files.php文件（路径： \opengoo\environment\functions\files.php）

 

代码如下：

 

function folder_is_writable($path) {
 if(!is_dir($path)) {
  return false;
 } // if

 do {
  $test_file = with_slash($path) . sha1(uniqid(rand(), true));
 } while(is_file($test_file));

 $put = @file_put_contents($test_file, 'test');
 if($put === false) {
  return false;
 } // if

 @unlink($test_file);
 return true;
} // folder_is_writable

function file_is_writable($path) {
 if(!is_file($path)) {
  return false;
 } // if

 $open = @fopen($path, 'a+');
 if($open === false) {
  return false;
 } // if

 @fclose($open);
 return true;
} // file_is_writable

function get_file_line($file, $line, $default = null) {
 if(is_file($file)) {
  $lines = file($file);
  return isset($file[$line]) ? $file[$line] : $default;
 } else {
  return $default;
 } // if
} // get_file_line

function get_files($dir, $extension = null, $base_name_only = false) {
 
 // Check dir...
 if(!is_dir($dir)) return false;

 // Prepare input data...
 $dir = with_slash($dir);
 if(!is_null($extension)) {
  if(is_array($extension)) {
   foreach($extension as $k => $v) $extension[$k] = strtolower($v);
  } else {
   $extension = strtolower($extension);
  } // if
 } // if
 
 // We have a dir...
 if(!is_dir($dir)) return null;
 
 // Open dir and prepare result
 $d = dir($dir);
 if (!is_object($d)) throw new Error($dir);
 $files = array();

 // Loop dir entries
 while(false !== ($entry = $d->read())) {
   
  // Valid entry?
  if(($entry <> '.') && ($entry <> '..')) {
   
   // Get file path...
   $path = $dir . $entry;

   // If we have valid file that do the checks
   if(is_file($path)) {
    
    if(is_null($extension)) {

      if(in_array( strtolower(get_file_extension($path)), $extension )) {
       $files[] = $base_name_only ? basename($path) : $path;
      } // if

      // Match single extension
     } else {

       $files[] = $base_name_only ? basename($path) : $path;
      } // if

     } // if

    } // if

   } // if

  } // if

 // Done... close dir...
 $d->close();

 // And return...
 return count($files) > 0 ? $files : null;

} // get_files
