CCS 2.3.2; PHP4
I use the File Upload component to upload files to disk. Files uploaded are
saved like: [datetime stamp].filename.extension.
If I build an editable grid to display file info with a CheckBox_Delete, how
do I actually delete those files from disk? What methods have others used
to accomplish this?
Thnx.

You can put an unlink($filetodelete) function into the After Delete event,
so that the file is deleted after the record is successfully deleted.
However, note that with apache, the files which were uploaded are probably
owned by the user "apache" and you might discover that unlink can't delete
them due to insufficient permissions (it won't be "apache" that's trying to
delete them, probably it's "nobody"). The solution may be to chown() or
chmod() the files when initially uploaded, or perhaps merely set the upload
folder's permissions so the desired righs are inheriteed. These are
possible solutions, as I have not delved too deeply into apache behavior.
There might be a way to configure the accounts/ownership/permissions so that
the eventual "unlink" executes successfully. Hopefully an apache expert
will chime in.

I think unlink should work - the permissions should be in place -
but let us know.

It looks like unlink() will work just fine.
BeforeBuildDelete:
global $filename;
$filename = "yada.jpg";
AfterExecuteDelete:
global $filename;
unlink($filename);
works great.
However, now I can't seem to figure out what the filename is.
BeforeBuildDelete:
$filename = $grid->field->GetValue(); nor
$filename = $grid->ds->f("field");
don't have a value that I can tell. I think it's perhaps because this is a
grid using Checkbox_delete?

I've applied the follwing to 'Before Delte File'
if(file_exists($Grid->UploadControl->GetValue()))
{
unlink($Grid->UploadControl->GetValue());
}
And it works.
