Question

I am trying implement a search activity which gets data from a mysql table based on a search.

I want to write a PHP script to use the string entered into the EditText and get the adjacent cell.

For example, Imagine there are two columns of the mysql table: Firstname and surname; I would like to be able to get the surname by searching the Firstname (Entering the Firstname into the EditText. I know this may require a SELECT Surname FROM Names WHERE ... query but how do I indicate the variable from my Java class?

The PHP script so Far:

<?php
mysql_connect("localhost","root","");
mysql_select_db("androidapp");
$sql=mysql_query("SELECT surname WHERE $get'fname'");
while($row=mysql_fetch_assoc($sql)) $output[]=$row;
print(json_encode($output));
mysql_close();
?>

Also, is the HttpGet method appropriate or HttPost method to do this, the result should display the surname in a TextView

Answer 1

i assume you want to send and receive data from php to java (android) through http post or http get. correct me if i am wrong.

basically what you want php to return is the row that matches the first name in the table.

mysql_connect("localhost","root","");

mysql_select_db("androidapp");

$fname = mysql_real_escape_string($_POST['fname']);

$result = mysql_query("SELECT surname FROM names WHERE fname = '$fname'");

//if you want only one record then
$row = mysql_fetch_array($result);

echo json_encode($row);

mysql_close();

always remember to escape the data for any sql injection with php’s mysql_real_escape_string() function. ans also i would prefer HTTP POST.

from your android application you will have to send a http request to the server where the PHP script is.

hope this helps you
