轉載 : 修改 FCKEditor FileManager 以支援刪除目錄及檔案的功能

原文網址 , 如下

http://www.castlesblog.com/2007/12/06/fckeditor-delete-filefolder/

怕有些人看不懂 , 我把我自己修改步驟寫下 , 我的版本是 2.6.1 且Server端程式是 PHP , 修改後運作很正常

1. 編輯 “fckeditor/editor/filemanager/connectors/php/commands.php” 增加下面三個 function

function DeleteFile( $resourceType, $currentFolder ) {
    $file = $_SERVER[‘DOCUMENT_ROOT’].$_GET[‘FileUrl’];
    if (is_file($file)) {
        unlink($file);
    } else {
        echo ‘<error number=”1″ originaldescription=”unable to locate file”>’ ;
    }
}
function DeleteFolder( $resourceType, $currentFolder ) {
    $folder = $_SERVER[‘DOCUMENT_ROOT’].$_GET[‘FolderName’];
    if (is_dir($folder) )   {
        DELETE_RECURSIVE_DIRS($folder);
    } else {
        echo ‘<error number=”2″ originaldescription=”unable to locate folder”>’ ;
    }
}
function DELETE_RECURSIVE_DIRS($dirname) { // recursive function to delete
    // all subdirectories and contents:
    if(is_dir($dirname))$dir_handle=opendir($dirname);
    while($file=readdir($dir_handle)) {
        if($file!=”.” && $file!=”..”) {
            if(!is_dir($dirname.”/”.$file)) {
                unlink ($dirname.”/”.$file);
            } else {
                DELETE_RECURSIVE_DIRS($dirname.”/”.$file);
            }
        }
    }
    closedir($dir_handle);
    rmdir($dirname);
}

2. 修改 “fckeditor/editor/filemanager/connectors/php/connector.php” 中的 switch 區段需要增加程式碼如下 , 請注意註解後面的兩段 case , 我用紅字標起來就是要新增的部份

switch ( $sCommand ) {
    case ‘GetFolders’ :
        GetFolders( $sResourceType, $sCurrentFolder ) ;
    break ;
    case ‘GetFoldersAndFiles’ :
    GetFoldersAndFiles( $sResourceType, $sCurrentFolder ) ;
    break ;
    case ‘CreateFolder’ :
        CreateFolder( $sResourceType, $sCurrentFolder ) ;
    break ;
    /******ADDED DELETE COMMANDS******/
    case ‘DeleteFile’ :
        DeleteFile( $sResourceType, $sCurrentFolder ) ;
    break ;
    case ‘DeleteFolder’ :
        DeleteFolder( $sResourceType, $sCurrentFolder ) ;
    break ;

}

3. 修改 “fckeditor/editor/filemanager/connectors/php/config.php” 中的設定 $Config[‘ConfigAllowedCommands’]

原來的應該是

$Config[‘ConfigAllowedCommands’] = array(‘QuickUpload’, ‘FileUpload’, ‘GetFolders’, ‘GetFoldersAndFiles’, ‘CreateFolder’) ;

需要修改成這樣

$Config[‘ConfigAllowedCommands’] = array(‘QuickUpload’, ‘FileUpload’, ‘GetFolders’, ‘GetFoldersAndFiles’, ‘CreateFolder’, ‘DeleteFile’, ‘DeleteFolder’) ;

4. 修改 “fckeditor/editor/filemanager/browser/default/frmresourceslist.html” 需要長的像這樣 , 這段有點長 , 主要是修改 oListManager.GetFolderRowHtml 及 oListManager.GetFileRowHtml 及新增 DeleteFile 及 DeleteFolder 兩個 function

oListManager.GetFolderRowHtml = function( folderName, folderPath, folderUrl ) //added folderUrl
{  
    // Build the link to view the folder.
    var sLink = ‘<a href=”#” mce_href=”#” onclick=”OpenFolder(\” + folderPath.replace( /’/g, ‘\\\”) + ‘\’);return false;”>’ ;
 
    return ‘<tr>’ +
            ‘<td width=”16″>’ +
                sLink +
                ‘<img alt=”” src=”images/Folder.gif” mce_src=”images/Folder.gif” width=”16″ height=”16″ border=”0″></a>’ +
            ‘</td><td nowrap colspan=”2″> ‘ +
                sLink +
                folderName +
                ‘</a>’ +
        ‘</td><td align=”right”><a href=”#” mce_href=”#” onclick=”DeleteFolder(\”+folderName+’\’,\”+ folderUrl.replace( /’/g, ‘\\\”) + ‘\’);return false;”>DELETE</a></td></tr>’ ;
}
 
oListManager.GetFileRowHtml = function( fileName, fileUrl, fileSize )
{     
    // Build the link to view the folder.
    var sLink = ‘<a href=”#” mce_href=”#” onclick=”OpenFile(\” + fileUrl.replace( /’/g, ‘\\\”) + ‘\’);return false;”>’ ;
 
    // Get the file icon.
    var sIcon = oIcons.GetIcon( fileName ) ;
 
    return ‘<tr>’ +
            ‘<td width=”16″>’ +
                sLink +
                ‘<img src=”‘+fileUrl+'” mce_src=”‘+fileUrl+'” border=”0″ style=”border:1px solid black; margin:5px;” alt=”” height=”70″ /></a>’ +
            ‘</td><td> ‘ +
                sLink +
                fileName +
                ‘</a>’ +
            ‘</td><td align=”right” nowrap> ‘ +
                fileSize +
                ‘ KB’ +
        ‘</td><td align=”right”><a href=”#” mce_href=”#” onclick=”DeleteFile(\”+fileName+’\’,\” + fileUrl.replace( /’/g, ‘\\\”) + ‘\’);return false;”>DELETE</a></td></tr>’ ;
}
 
function DeleteFile( fileName, fileUrl )
{
    if (confirm(‘Are you sure you wish to delete ‘ + fileName + ‘?’)) {
        oConnector.SendCommand( ‘DeleteFile’, “FileUrl=” + escape( fileUrl ), Refresh ) ;
    }
 
}
 
function DeleteFolder( folderName, folderPath )
{
    if (confirm(‘Are you sure you wish to delete \” + folderName + ‘\’ and all files in it?’)) {
        oConnector.SendCommand( ‘DeleteFolder’, “FolderName=” + escape( folderPath + folderName ), Refresh ) ;
    }
}

5. 繼續編輯檔案 “fckeditor/editor/filemanager/browser/default/frmresourceslist.html”

在 GetFoldersAndFilesCallBack 這個 function 中找到一行

oHtml.Append( oListManager.GetFolderRowHtml( sFolderName, sCurrentFolderPath + sFolderName + “/” ) ) ;

修改為

oHtml.Append( oListManager.GetFolderRowHtml( sFolderName, sCurrentFolderPath + sFolderName + “/”, sCurrentFolderUrl ) ) ;

好啦 !! 大功告成 ^^

以上 5 個步驟基本上就可以讓 FCKEditor 具備刪除的功能 , 但這個刪除法的原始作者有修改檔案圖示變成小圖預覽 , 可能有人覺得不習慣 , 其實我也不習慣 , 所以我又把  “fckeditor/editor/filemanager/browser/default/frmresourceslist.html” 中的 oListManager.GetFileRowHtml 改成如下 , 還原成預設的檔案圖示

oListManager.GetFileRowHtml = function( fileName, fileUrl, fileSize )
{
 // Build the link to view the folder.
 var sLink = ‘<a href=”#” mce_href=”#” onclick=”OpenFile(\” + ProtectPath( fileUrl ) + ‘\’);return false;”>’ ;

 // Get the file icon.
 var sIcon = oIcons.GetIcon( fileName ) ;

 return ‘<tr>’ +
   ‘<td width=”16″>’ +
    sLink +
    ‘<img alt=”” src=”images/icons/’ + sIcon + ‘.gif” width=”16″ height=”16″ border=”0″><\/a>’ +
   ‘<\/td><td> ‘ +
    sLink +
    fileName +
    ‘<\/a>’ +
   ‘<\/td><td align=”right” nowrap> ‘ +
    fileSize +
    ‘ KB’ +
  ‘<\/td><td align=”right”><a href=”#” mce_href=”#” onclick=”DeleteFile(\”+fileName+’\’,\” + fileUrl.replace( /’/g, ‘\\\”) + ‘\’);return false;”>DELETE</a></td><\/tr>’ ;
}

後記 :

後來在 FCKEditor 官網發現到有 CKFinder 這套 . 真是很棒的檔案瀏覽器 , 而且對於安全性上有做處理 , 自己試用過後不錯 , 但也是屬於要付費的 , 不過不付費也可以使用 , 相關的 License 說明官網有 , 也是處於模糊地帶可以用在非商業行為上 ..
