php cannot call python

manpreet Best Answer 2 years ago

When I call a simple python-script that blinks LED once, from a PHP-script via browser, nothing happens.

and I add these lines in the sudoers file.

apache ALL=(ALL) NOPASSWD: ALL
apache2 ALL=(ALL) NOPASSWD: ALL
www-data ALL=(ALL) NOPASSWD: ALL
adm ALL=(ALL) NOPASSWD: ALL

/var/www/html owner&Group is www-data and python script owner&Group is www-data also

what is the problem?

php
if (isset($_POST['RedON']))
{
exec('sudo python /var/www/html/xbee.py');
}
if (isset($_POST['RedOFF']))
{
exec('sudo python /home/pi/xbee2.py');
}
if (isset($_POST['YellowON']))
{
exec('sudo python /var/www/html/xbee2.py');
}
if (isset($_POST['YellowOFF']))
{
exec('sudo python /var/www/gpio/yellow_off.py');
}
if (isset($_POST['GreenON']))
{
exec('sudo python /var/www/gpio/green_on.py');
}
if (isset($_POST['GreenOFF']))
{
exec('sudo python /var/www/gpio/green_off.py');
}
?>
