Hello,

I'm using the upload components for uploading some images and videos. The problem I'm having is that when people upload files with spaces or special characters in the filename I'm having problem displaying them on my site.

I know that CCS modifies the filename and adds the file uploaded timestamp, but in addition to that, I want to rename the file, I need it to be only alphanumerical numbers and underscores (_).

For example, someones uploads a file named: "video de área prueba del año.flv"
I want it to me renamed to: 200806271527420.video_de__rea_prueba_del_a_o.flv

In other words, any character other than alphanumerical and underscores will be replaced with an underscore (_).

Any idea where I could change this?

Thanks
G

Hi

Here is where you would make that change. I have ran into the same problem and had to fix it also

You can make the fix in Classes.php

In the fileupload object you will see where ActualFileName gets the timestamp added.

After that code use string replace and just replace spaces with the underscore.

Works like a gem.

Thanks, That work....

Added this to the clsFileUpload class:

$replace_filename = array("á", "é", "í", "ó", "ú", "ñ", "Á", "É", "Í", "Ó", "Ú", "Ñ", "¿", "?", "!", "'", " ");

Then modified this line:

$ActualFileName = date("YmdHis") . $index . "." . str_replace($replace_filename, "_", $FileName);

You Guys Rock!!!!!

This has solved a problem I have had for some time and will save me a lot of emails and frustrated students.

Is this something YES ought to think about implementing?

Thanks again.

Hi

I sent this fix to YES back in version 3 along with several other fixes like FCKeditor failing on hidden controls, MySql error processing.... etc.

In every case they say they will consider fixing the bugs but they never seem to do it.

We are now on version 4 and no fixes for this and others have appeared.

Have fun..

Hi all

Here is my working code:

Add it after this:
// move uploaded file to temporary folder
$file_exists = true;

  
$replacefilenamesrc = (array ("á", "é", "í", "ó", "ö", "ő", "ú", "ü", "ű", "Á", "É", "Í", "Ó", "Ö", "Ő", "Ú", "Ü", "Ű", "ľ", "Ľ", "š", "Š", "č", "Č", "ť", "Ť", "ž", "Ž", "ý", "Ý", "ä", "ň", "Ň", "ô", "ď", "¿", "?", "!", "'", " "));  
$replacefilenamedst = (array ("a", "e", "i", "o", "o", "o", "u", "u", "u", "A", "E", "I", "O", "O", "O", "U", "U", "U", "l", "L", "s", "S", "c", "C", "t", "T", "z", "Z", "y", "Y", "a", "n", "N", "o", "d", "_", "_", "_", "_", " "));  
  
$NewFileName = str_replace($replacefilenamsrc, $replacefilenamedst, $FileName);

And replace $FileName in the line:

$ActualFileName = date("YmdHis") . $index . "." . $FileName;

with $NewFileName

Final code is:

$ActualFileName = date("YmdHis") . $index . "." . $NewFileName;
