      use only the script bellow “Brand new simple code to deliver JSON POST from Android to PHP” or only the script above “Brand new simple code to deliver JSON POST from Android to PHP”..

      you need to learn basic Java programming if you were new to this project, or you can find any tutorial about how-to make android projects using eclipse over the internet..

      this thread only shows how-to build simple client-server application using android as a client and PHP as a server..

    The php side of the script is giving me an error😦
    Undefined index: HTTP_JSON in C:\wamp\www\post.php on line 2
    Could you help resolve this?

     
    • fahmirahman

      June 30, 2011 at 13:16:55

      you can see at the main.java line 56 – 58 :

      // Post the data:
      httppost.setHeader(“json”,json.toString()); <– this script made the header HTTP_JSON
      httppost.getParams().setParameter(“jsonpost”,postjson);

      So if you dump the $_SERVER on your PHP server side using var_dump($_SERVER) you must be see the HTTP_JSON header there..
      ” Undefined index: HTTP_JSON in C:\wamp\www\post.php on line 2 ” <– this is error code that given by WAMP that notice HTTP_JSON header doesn't exist on your server header.
      There's probably something wrong with your apache config for PHP or I suggest you using LAMPP..🙂

        Thanks so much for the hint. My error was that I was viewing the php file from my wamp server and expecting some output. I didn’t understand that the URL included the json header. No wonder it was showed me Undefined index error. Thanks so much🙂

      I suggest you better use LAMPP for PHP server rather than TOMCAT..🙂

      Do you mean WAMPSERVER running on local host ?? Is that the case you have to use a URL something similar to this. http:\\10.0.2.2\phpfilename.php

    Hi Fahmi,

    Thanks for this fantastic post!

    However i have used your code above and getting the following error in the emulator after trying to post the JSON object to my server:

    “An unexpected error occurred”

    Do you have any idea what might be causing that?

    Thanks

    heyy
    thanks for this hope-giving post

    but what should happen if u let the app run?
    ive pasted ur first script without the JSON and well the app starts, i get a blank application and nothing happens

    than i tried to combine ur previous food-database-connection post with this post and it says “application stopped unexpectedly.please try again”

    im using Xampp

    should i use Wampp or Lampp or an other?
    i really dont know what to do anymore ^^

    Thanks fahmirahman !
    Finally successfull, althought I had to change something : I had to place a big part of your code into an async task.
    To do such a thing, I’ve been inspired by Chathura here :
    http://codeoncloud.blogspot.fr/2013_07_01_archive.html
    His code works fine, I just adapted it to pass parameters to a php script.
    If anyone here is interested, I’ll post the source code of Activity_main.java.

    Hey, this is incredibly helpful, but I have a few questions. Could you explain what exactly setHeader() is doing, and what $_SERVER[‘HTTP_JSON’] retrieves from the server?

    Greetings! Quick question that’s entirely off topic. Do you know how to make your site mobile friendly?

    My blog looks weird when viewing from my apple iphone.
    I’m trying to find a template or plugin that might be able to resolve this issue.

    If you have any recommendations, please share. Thanks!

    Hello,
    I read your example and want to use it for my project. But it doesn’t work. I don’t an error as response. So i an echo count($dataarray); inide the php document. It returns always size 1.

    If I post the Data as the following

    httppost.setHeader(“json”,postjson.toString());

    , It works. But then I only can send an array of 70 elements because otherwise server returns the following message.

    400 Bad Request

    Bad Request
    Your browser sent a request that this server could not understand.
    Size of a request header field exceeds server limit.

        json
        

    Apache/2.4.12 (Win32) OpenSSL/1.0.1m PHP/5.6.11 Server at localhost Port 80

    Can you help me to find out why post the Data as shown in your example doesn’t work for me?
