I am converting an existing web GUI to include SANE compatibility . I am working on getting things like scanner info , etc .
When the web GUI executes a shell_exec(scanimage -T -d scannername) from PHP , I get nothing on the web GUI . I can echo the command and paste into terminal and it works. I can also use shell_exec(scanimage -L) and shell_exec(scanimage -V) successfully, as well as initiate a scan I am using the test backend and maybe this has something to do with it? I have added www-data (debian web user) to the groups saned, scanner and adm and still no luck with the one command from web server Thanks Mark
