Question

I’m working on a program that sends data to a server. The server is receiving my data, but only the last bit of it. Here’s my Android code:

ArrayList<NameValuePair> j2 = new ArrayList<NameValuePair>();
j2.add("drink_name", "rootbeer")
j2.add("drink_name", "pepsi")

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("kubie.dyndns-home.com/R2Bar2/getingredients.php");
httppost.setEntity(new UrlEncodedFormEntity(j2));
HttpResponse response = httpclient.execute(httppost);
responseText = EntityUtils.toString(response.getEntity());

But it’s only adding the last entry (pepsi) to the database.
Here’s my php:

 <?php 
$handle = mysql_connect('localhost','root','xxxx'); 
if($handle==false) 
{ 
die('No database connection'); 
} 

$result = mysql_query("TRUNCATE TABLE 'available_ingredients'");

$db=mysql_select_db('r2bar2'); 
$query='INSERT INTO available_ingredients (drink_name) VALUES ("'.$_POST["drink_name"].'")'; 
$result=mysql_query($query); 
?>

Answer 1

try this

j2.add(new BasicNameValuePair("drink_name[]", "rootbeer"));
j2.add(new BasicNameValuePair("drink_name[]", "pepsi"));

what you’re putting in your entity is a List of NameValuePair — so each thing you add should be a NameValuePair, and the BasicNameValuePair is one of those

in the php

<?php
foreach ($_POST["drink_name"] as $drink_name) {
    $query=...
    $result=...
}
?>

but a note of caution — make sure you call mysql_real_escape_string on your inputs to guard against SQL injection attacks.
