Then in pass2php.php add this:
Code: Select all
<?php
lg($device.' = '.$status)
Then we know that the path and filename is good.

this one i don`t understand? This is the same line you ask me to comment out in pass2php.php?

Yes, but now it's placed inside pass2php/TEST.php
We need to check step by step where the script stops by adding lg commands.

Edit: oh, sorry, forgot to change the filename in my previous post.

Ok now i understand... you said to put this line pass2php.php. If i put this line in pass2php/TEST.php nothing happens in the log when i press the switch:

Wait a minute, where did you get this part?

Code: Select all

if(@include 'http://127.0.0.1/secure/pass2php/'.$device.'.php'){

That should be a path, not a url:

Code: Select all

if(@include '/volume1/web/secure/pass2php/'.$device.'.php'){

Permissions are good on the folder/file so the user that runs the webserver can read them?

found the error i think.... when running as user pi i get a acces denied error. How can i change apache2 settings to run command as root without losing security....

or maybe its better to move the map to a new dir under /home/pi/ ?

EDIT: changed file to another directory which pi user has rights to but still nothings happens when pressing TEST switch.

Code: Select all

<?php error_reporting(E_ALL);ini_set("display_errors","on");date_default_timezone_set('Europe/Amsterdam');

		}else apcu_store('s'.$device,$status);
		apcu_store('t'.$device,time);
		$dev=$device;

}

output of cat:

raspberrypi% cat /home/pi/domoticz/scripts/lua/pass2php/pass2php/TEST.php
<?php
lg($device.' = '.$status)
if($s['TEST']=='On')sw($i['Verlichting Dressoir'],'On');

Never run a webserver as root...
You should check under wich user your webserver runs, mostly www-data or similar
That user needs access to the secure/pass2php folder and the TEST.php file

Its running as user and group pi

EDIT: Ok changed everything back to www-data and make www-date the owner of var/www folder. Added pi to the user-group www-data and set the permission to 775.... But still nothings happens when i press the switch button

Looks like the TEST.php isn`t being found or something.. is there anyway to log this which call is being made (or isn`t made)

make a file /var/www/test.php:

Code: Select all

<?php
error_reporting(E_ALL);
ini_set("display_errors","on");
include('/var/www/secure/pass2php/TEST.php');

Call the page in your browser http://192.168.x.x/test.php
Output must be something like 'call to undefined function lg...' because that function doesn't exist in that file.
I'm expecting a output like 'file not found', or 'permission denied',...

You are right.....

Code: Select all

Warning: include(/var/www/html/secure/pass2php/TEST.php): failed to open stream: Permission denied in /var/www/html/test.php on line 4

Warning: include(): Failed opening '/var/www/html/secure/pass2php/TEST.php' for inclusion (include_path='.:/usr/share/php') in /var/www/html/test.php on line 4

so there are still permission issues. Do you have some guide to set the permissions the right way...

Thanx for helping me out so fast! really appreciate it

If www-data is the user that runs the webserver

sudo chmod 755 /var/www/secure
sudo chmod 755 /var/www/secure/pass2php
cd /var/www/secure
sudo chmod 644 *
cd /var/www/secure/pass2php
sudo chmod 644 *

So, 755 for dirs (read/write/execute for owner, read/execute for others) and 644 for php files (read/write for owner, read for others).

ok did this all but makes no changes... still getting acces denied. Is this because domoticz is running as pi? or is this all php related?
Or do i have to restart apache or php or something after this changes?

This is apache related, but very strange.
Are there other files in /var/www
otherwise, chmod everything
sudo chmod -R 777 /var/www
that gives everybode read/write/execute permissions on /var/www and everything below that.

And you're sure /var/www/html is the root of Apache? Isn't that normally just /var/www?

on raspbian jessie this has changed to /var/www/html if have read somewhere. Now did chmod 777 and now it executed at least its giving me another error instead of acces denied:

Code: Select all

Parse error: syntax error, unexpected 'if' (T_IF) in /var/www/html/secure/pass2php/TEST.php on line 3

EDIT: Have it working now... was missing ";" after log line

now the output in domoticz is this when pressing the switch TEST:

Code: Select all

2017-01-30 18:16:45.317 User: Admin initiated a switch command (563/TEST/On)
2017-01-30 18:16:45.317 (Dummy) Light/Switch (TEST)
2017-01-30 18:16:45.798 => TEST = On

this is my code in TEST.php:

Code: Select all

<?php
lg($device.' = '.$status);
if($s['TEST']=='On')sw($i['Verlichting Dressoir'],'On');
if($s['TEST']=='Off')sw($i['Verlichting Dressoir'],'Off');
?>

I see the log but nothing is happening when i flip the switch.... Should is see a log line when php is trying to sending a command to domoticz?

Lol, yes, a simple ; can break a whole script.
It should have been in the domoticz log, if you look at it in bash (not in web ui).

what do you mean look into the log in bash? Is there another way to acces domoticz log and does that give more information why my switch is not switching? Maybe i need the code with APCU command in it because all is stored now with APCU_store ?

EDIT: Have something working but it only switch when using the IDX... This code is working for turning my test lights on and off:

Code: Select all

<?php
lg($device.' = '.$status);

if ($status=="On") {
	lg("Switching on..");
   sw(580,'On');
} else {
	lg("Switching off...");
	sw(580,'Off');
}

Result in domoticz:

Code: Select all

2017-01-30 20:21:29.916 User: Admin initiated a switch command (563/TEST/On)

But when i try to use the sw functions this way it doesn`t work :

Code: Select all

 sw($i['Verlichting Dressoir'],'On');

and when using apcu this isn`t working also:

Code: Select all

sw(apcu_fetch('sVerlichting Dressoir'),'On');
