Set error log level to info. After that the module will start logging  
which file it started/stopped uploading, it’s content type and temporary  
path.

upload\_set\_form\_field  
($upload\_file\_name,$upload\_file\_type,$upload\_tmp\_path).can i print this  
variable in log file.can i use  
seperate log file for to print this variable.if it is possible how can i

mr Valery,

```
       Thanks for Information .now I am Seeing the information of

```

that file is getting printed in the log file .when i chenge log level to  
info it is printing automatically info into log file.In this upload  
module i want to add checksum and size of the file of that file to get  
printed in that log file . can i do that?if it is , how? because you  
have written upload\_aggregate\_form\_field directive ($upload\_file\_md5  
,$upload\_file\_size).these variables are used to store checksum and file  
size .i want these values to get printed in that log file.if it  
possible?

Thanks For the Reply

An alternative could be a directive in upload module that logs a line  
per file into the error log. May be one day I’ll implement it.
