You have an exemple on how you design your database?

I can’t answer your question but I can give you some clues to get to it. Use FireFox with FireBug. FireBug has a tab called “Net”. This tab displays the browser traffic. With Firebug open, you just click on the submit button of the form that you want to simulate and look in the “Net” tab to find the Post Request headers that was sent to google.

Other thing to keep in mind is that the request needs to end with an empty line. You example does not have that at the end. It only adds a new line char after print(data) but does not add an extra empty line)

Hope this helps.

My code is, but doesn work

client.println(“POST /forms/d/……../formResponse HTTP/1.1”);
client.println(“Host: docs.google.com”);
client.println(“Content-Type: application/x-www-form-urlencoded”);
client.println(“Connection: close”);
client.print(“Content-Length: “);
client.println(data.length());
client.println();
client.print(data);
client.println();

Alternative is write code on the Arduino that prints the results from the post request on the serial port.(Make the Arduino print the 1’s 😉
Here are some example code of how to retrieve a webpage -> http://bildr.org/2011/06/arduino-ethernet-client/

It uses client.read();

I have added a second PHP page that will similate what the Arduino is doing. Just make sure to point the second test page to the
correct URL on the line with : FORM action=”abovePage.php”.

< ?php echo 'test'; ?>

Are you running Apache or IIS?

I find that the best way to debug scripting languages is by using elimination. Remove parts of the script you think might be broken and re-test. If it does work without the stuff you took out, you know the part that is left is good(So the working bit has been eliminated). Then add bits back till you find the line with the issue. If you can enable PHP warnings it will be a huge help cause that will point you to the line that is not working.

This works for Arduino’s to. Serial.print’ing debugging info so you can get a better idea of what gets sent/received.

I have made some bug fixes on the sketch. It should now output the Post request on the serial port.

I have also added a PHP example of how it processes the data from the Arduino.

The PHP side works by looking at the Post Data. (That will be the data variable in our script). To retrieve
that in PHP you use the following command : $_POST[“data”] and $_POST[“submit”]

Does that answer your question?

Sorry for my bad english !

Yes… I manged to get this working very well.
My setup:
# Arduino Duemilanove/Uno
# Wiznet ethernet brick. (Same setup as Arduino Ethernet Shield)
# A post request was sent to my webserver every 10 seconds.(Temp+Humid)
# The server page is PHP page that takes the post data and inserts it into a MySQL DB.
# JQuery Mobile + PHP + Google Charts to display the graphs on my production system.

Have you manually tested the post command before trying it on the Arduino?
