Want to release a contrib.... but it does not work

February 17, 2015

So i had this thing that worked before, but after the hoster upgraded php for some reason it does not work

What is it?

Its a set of php files placed in the root folder that are able to list pending orders, list the order data, change the status....

then on a raspberry pi i have a python script (not made by me) that first calls the first files that list all order with the status of 1 (pending)

it then prints out each order...(on a thermal printer in my case)

then changes them to processing and lets the customer know

each time at midnight it changes them to finished

it was made for a pizza delivery that does not have time to check for new orders, nor have time to go and change the status

and the customer would not need to know the day after that they ate a pizza...

until the hoster upgraded their php it has worked....

the php files on the server does still list order numbers when i call them in a browser

but for some strange reason the python script now see's the order number+status as a float and not 2 numbers with a space between...

i want to release this but not before its working...

anyone that can help me with that?

python script is here: https://github.com/boelle/OSCommerceClient/blob/master/OSCommerceClient.py

the files for the root folder is here: https://github.com/boelle/OSCommerceClient/tree/master/php-files

the project initial started out on the arduino platoform but found out a pi was better suited...

when i run the py script i get this error (temp i have made it print to screen what the order number is and the status):

pi@raspberrypi ~ $ sudo python OSCommerceClient.py

Serial printer enabled

Starting polling

anyone that can see where in the code it goes wrong for me? i'm total lost since it has worked for almost an year now....

EDIT: i have made this printer for 3 pizza deliveries.... one is of course not currently working... the others are....

if i call up the file that list pending order on the one that works it is encoded as windows-1252 the other that is not working is UTF-8 (as reported by chrome browser)

otherwise if i ask for details in chrome i get this:

<html>

<body>

"[432 1,"

<br>

"OK]

"

</body>

</html>

its the same for both sites...

so cant it be just the encoding alone that can throw it off? and if so how to i change the encoding on those files alone? is the simpelts way to throw them in a sub folder?

Your script does logging... find the file and see if it printed anything

 
import logging//line17


 logging.debug("processing order "+order);  //line 120
 logging.debug("found order "+str(orderNum)+" status "+str(status)+",")//line 125
 logging.debug("skip order "+str(orderNum)); //line 130
 logging.debug("OK at end of list"); //line 133

Also in above code you have your ip adress listed for the server, is that still the correct IP? (somehow i have a feeling it is where the problem is)

that part of the code is not used.... only the address listed instead of test.com is used.

i plan to clean the code when i have it working again

EDIT: i see the import logging.... but how do i know what file to search for?

i guess this is the downside of having other people do code for you... harder to debug :-/

Btw... how do i force a charset on a single file in root folder? i tried various tricks via htaccess but chrome still reports utf-8

wanted to test if it made a difference if the php page i call can encoding to something different

EDIT2: added this under import logging: logging.basicConfig(filename='example.log',level=logging.DEBUG)
