I'm uploading an ms-excel file with this _cm_uploadFile function

function _cm_fileUpload ($input_name, $temp_file, $wherearray)
{
$file_name = $input_name;
$this->_processFile($temp_file);

return $file_name;
}

The processFile function loads the excel.php file (attached), during the process the screen remain with uploadFile screen, finishing the process the screen turns white.
Any idea why it happens??
Thanks for advance.

You are not uploading an excel file if it as a file extension of '.php'.

If you look inside the 'std.fileupload1.inc' script you will see that it has a blacklist of files which have the 'php' or 'htm' extension. You are only supposed to upload data, not files which could potentially alter the functioning of a web application.

Excuse me, my mistake, english is not my native language; what I mean is that I upload an excel (any .xls on disk) file then process it using the class wich is coded in the excel.php file, then the screen turns white.

You should not be using the _cm_fileUpload() function in this way as the file has not actually been uploaded yet. That method is only supposed to be used for altering the file name. You need to use the _cm_post_fileUpload() method instead.
