Sending Android Data To Script?

I am developing an application that will involve interaction with a MySQL database whereby the posted data is handled using PHP. From an Android app, i send HttpRequests to a PHP file [at localhost], which creates a connection to a MySQL database and drops some data in a table.

The problem that I am having is that I have installed XAMPP [Apache server, MySQL] but when I start the Apache service, and start the Android application it doesn't fetch any data. What are the best requirements that will help me get out of this mess so that I may connect my Android app to a MySQL database then do some scripting using PHP?

Fetch Data From Android To Webserver?

I have a certain concept in mind, but I an unsure what my possibilities are.

User enters a name (html form) on a webpage Webserver sends push notification to the Android device of the user Application looks for this name in the contactslist and finds the corresponding phone number
Application instantly sends this information back to the webserver, where the user can use the returned phone number.

The only step I am unsure about is #4. I presume I'd have to use a temporary MYSQL database and use reverse AJAX or something alike to get the returned data to the user without him having to refresh the page (this entire process needs to be completed within a couple of seconds at most - the faster, the better).

Pass Data From Android To Mysql?

Ive been trying to send gps data from my android app to a mysql database using php but Im not sure if everything is set up right because I can see through the logcat that the data is being sent from android but its just not getting sucked up by the database.Aside from some recommendations does any body have any tutorials that would show specifically the php to server code.Also is it pssible to just send the data straight to the database without something like php? I dont think so but I had to ask.here is the php that I am using with the addresses and stuff taken out for obvious reasons.

In my android App I obtain the HttpResponse that contains 1 or 0.But is this safe? Using echo is the best way to obtain an answer from the script?

Android App Sends Data To Script - Expectation Failed V2.0?

I have asked a question recently on StackOverflow: Android app sends data to PHP script - Expectation failedI didn't get the expected answer so I try another time with new clues.First, I've found someone who gets the same error on this website: http://www.anddev.org/novice-tutorials-f8/doing-http-post-with-the-current-sdk-t5911-15.htmlI've tested every code on this forum and other websites, sanitizing them or using as written, but I always return the same error: 417 Expectation Failed.. I don't know anything about status error different from 404, 500, and so on..Chances are the reason why your code isn't working is because you don't understand how to build an HTTP request. The code is fine, your headers and content probably isn't!Using a network protocol analyser (such as Wireshark), or FireBug or Chrome's built in development tools, read the POST requests you make to websites then rebuild them (using the same headers) in Android.

Add Name Value Data To An Android HTTP File Upload POST Request?

I have an android photo upload script that uploads fine if I use $_GET to read some data, I want to use all $_POST. The problem is I need to append data do the posted request to include basic name value pairs along with the file upload. I can get this to work if I have the server use $_GET and just add the extra data in the url string, but I want to use post. Is there a way to encode other post data in the file upload that the server can read using $_POST. Heres the function, notice the URL string where, I'm trying to get the variables api_key,session_key, and method to be sent in the POST request.

public void uploadPhoto(FileInputStream fileInputStream, String sessionKey) throws IOException, ClientProtocolException {
URL connectURL = new URL(API_URL +"?api_key=" +API_KEY+ "&session_key=" + sessionKey + "&method=" + ApiMethods.UPLOAD_PHOTO); //server ignores this data

[code]....

EDIT: I'm thinking something like the following is needed for each added param

dos.writeBytes("--" + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data;name=api_key=" + lineEnd + lineEnd + API_KEY);
dos.writeBytes(lineEnd);
dos.writeBytes("--" + boundary + "--" + lineEnd);

Android JSON HttpClient To Send Data To Server With HttpResponse?

I am currently trying to send some data from and Android application to a php server (both are controlled by me). There is alot of data collected on a form in the app, this is written to the database. This all works. In my main code, firstly I create a JSONObject (I have cut it down here for this example):

JSONObject j = new JSONObject();
j.put("engineer", "me");
j.put("date", "today");
j.put("fuel", "full");
j.put("car", "mine");
j.put("distance", "miles");

Next I pass the object over for sending, and receive the response:

[Code]...

However the data received on the server cannot be parsed to a JSON string. It is badly formatted I think (this is the first time I have used JSON): If in the php file I do an echo on $_POST['vehicle'] I get the following: {"date":"today","engineer":"me"} tell me where I am going wrong, or if there is a better way to achieve what I am trying to do?

When I do that, the new page appears and the new page receives the value for the first variable. For some reason the second and third parts of the data aren't received in the new page, although they are present right before this line in the sending page. What am I doing wrong?

Data Interaction Before Sending To DB

Using Macromedia MX with PHP 4.

I have created a page that enables a new table entry into my database. This was done using the MX wizard - and works fine.

My Question:
I have a tick box that can be checked as part of the data. I want to automatically complete one of the database fields with the current date and time when the tick box is checked.

How do I:

1. Capture the tick event?
2. Pass a variable in PHP containing the date / time into the Form Input box, or directly into the database?

Sending Binary Data Via UDP

I'm trying to send a packet of binary data to a UDP server. If I send
a text string, it works fine. If I attempt to send binary data, it
sends a UDP packet with 0 bytes of data (just the headers). I can see
this because I'm running Ethereal and watching the packets.

I'm defining the packets as shown below:

$text_msg = "Hello, world
";
$binary_msg = chr(0x01).chr(0x02).chr(0x03).chr(0x00).chr(0xA0);
$binary_msg_size = 5;

Initially, I tried using
$fp = fsockopen("udp://" . $server,$port,$errno,$errstr)
and
fwrite($fp,$binary_msg,$binary_msg_size)

Since this didn't work, I then tried
$sock = socket_create(AF_INET,SOCK_DGRAM,SOL_UDP);
and
socket_sendto($sock,$binary_msg,$binary_msg_size,0 ,$server,$port);

For both methods, sending $text_msg worked, but sending $binary_msg
resulted in a UDP packet with 0 data bytes being sent.

I've found examples of sending binary data, but they used TCP, and
I've found examples of sending UDP, but they send text strings.

Anyone have experience with sending binary data to a UDP server?

Data From Form Not Sending?

I'm having an issue with receiving form data to my mail server.

It's very basic, but I need some experienced eyes on it. It sends to the recipient (me) correctly, I receive the sender info in the email. When sent, it directs the viewer to the page I want.

in the body of the email, I get this :

From:
E-Mail:
Message:
period : Within 1 month

It appears the "period" field is working correctly, however, some other fields are missing like the name and type field. It also looks like the message, and from fields carry no data over. In other words, I type in a message and click submit, message doesn't not appear in the email.

Code:
<?php
$to = "myemail@mydomain.us";
$subject = "Contact Us";
$name = $_REQUEST['name'];

Sending Data To My Database

I have ms access database (im know mysql is better but please bare with me) and within it  is a product list. That product list is called and displayed on my product page. After the price of an item has been echo'ed out i have a small text field where the user of the system is required to type the product id ($ProductId) on all the items they wish to select and then proceed to click submit.

Once the submit button has been pressed i want to send all of the data typed into the little text fields into a single cell separated by commas in the database.

Product 1  <----i want this one
Product 2
Product 3
Product 4
Product 5 <-----I wantthis one

I just get ',,,' sent tothe database however if i type product id like this:

Product 1  <----i want this one
Product 2  <----I want this one as well
Product 3  <----i want this one too
Product 4
Product 5

I get 1,2,3 sent into the database. Code:
