XUpload - Block certain characters in file naming.

[ap]

Is there a way to program in the config file a way to alert a user if their file names contain any special chracters like @, #, %, etc. It would be nice to alert a user that they used a character not support in their file names. Like the way the script only allows certain extensions. Macintosh has a problem with certain chacters.

There's filaname_mask option in config in Pro version. But it don't show alert, just don't save file and set status=unallowed filename in POST request.
You can validate filename when selecting file with JS. Just add another regexp in checkExt function in xupload.js

Not sure I followed you on this. What do I need to add, and where under the .js script and under the config script. Thanks

Ok then

In xupload.js update checkExt() function to this:

Code: Select all

function checkExt(obj)
{
    value = obj.value;
    if(value=="")return true;
    var re = new RegExp("^.+\.("+ext_allowed+")$","i");
    if(!re.test(value))
    {
        alert("Extension not allowed for file: \"" + value + "\"\nOnly these extensions are allowed: "+ext_allowed.replace(/\|/g,',')+" \n\n");
        return false;
    }
    var re = new RegExp("[\@\#\%]","i");
    if(re.test(value))
    {
        alert("Selected filename contain bad characters!\n\n");
        return false;
    }
    return true;
}

In this function we show error if filename contain '@','#','%'. You can add other 'bad' symbols to RegExp.

That seems to do the trick. Thanks
