    Filename pattern

    Hello
     
    is it possible to restrict allowed filenames through a regex pattern like in the cuteeditor ?
     
     <security name="filenamePattern">^[a-zA-Z0-9\._-]+$</security>
     
    thanks,

    Hi Luuuukke,
     
    You can limit the file name by your own logic in API "CuteWebUI_AjaxUploader_OnSelect" and use method Cancel() to remove it if not match your request. Please try the example below.
     
    "files" is the selected file list. files[i].FileName is the upload file name. 
     
    More detail about the API please refer to http://www.ajaxuploader.com/document/scr/JavaScript-API.htm

    Re: Filename pattern

    Thanks, it works fine :)
     
    in case somebody needs it, here is a check with regex  to disallow whitespaces & special chars in file names
     
     <script>
         function CuteWebUI_AjaxUploader_OnSelect(files) {
             var re = new RegExp('^[a-zA-Z0-9\._-]+$');
             for (var i = 0; i < files.length; i++) {
                 var m = re.exec(files[i].FileName);
                 if (m == null) {
                     files[i].Cancel();
                     alert('The file "'+files[i].FileName + '" was not uploaded (unauthorized filename)');
                 } 
             }
         }  
    </script>

    Re: Filename pattern

    A comma-separated list of regular expressions, used to filter the attachments by file name. Note that the parameter values must be regular expressions. For example:
    To match a file suffix of 'jpg', use .*jpg (not *.jpg).
    To match file names ending in 'jpg' or 'png', use .*jpg,.*png
