Getting json response for android from PHP
Question
I am newbie in php, kindly pardon me if I looks silly. I am still learning step by step with the help of online forums and stack community.
I have a form online which code is as below:
<?php
define('DIR_APPLICATION', str_replace('\'', '/', realpath(dirname(__FILE__))) . '/');
include(DIR_APPLICATION."config.php");
ob_start();
session_start();
$msg = 'none';
$sql = '';
if(isset($_POST['email']) && $_POST['email'] != '' && isset($_POST['password']) && $_POST['password'] != ''){
if($_POST['usertype'] == 'admin'){
//here for admin
$sql= mysql_query("SELECT * FROM admin WHERE a_email = '".make_safe($_POST['email'])."' and password = '".make_safe($_POST['password'])."'",$link);
}
else if($_POST['usertype'] == 'teacher'){
//here for teacher
$sql= mysql_query("SELECT * FROM teacher WHERE t_email = '".make_safe($_POST['email'])."' and t_password = '".make_safe($_POST['password'])."'",$link);
}
else if($_POST['usertype'] == 'student'){
//here for student
$sql= mysql_query("SELECT * FROM student WHERE s_email = '".make_safe($_POST['email'])."' and s_password = '".make_safe($_POST['password'])."'",$link);
}
else if($_POST['usertype'] == 'parents'){
//here for parent
$sql= mysql_query("SELECT * FROM parent WHERE p_email = '".make_safe($_POST['email'])."' and p_password = '".make_safe($_POST['password'])."'",$link);
}
else if($_POST['usertype'] == 'librarian'){
//here for employee
$sql= mysql_query("SELECT * FROM user WHERE u_email = '".make_safe($_POST['email'])."' and u_password = '".make_safe($_POST['password'])."'",$link);
}
else if($_POST['usertype'] == 'accountant'){
//here for employee
$sql= mysql_query("SELECT * FROM user WHERE u_email = '".make_safe($_POST['email'])."' and u_password = '".make_safe($_POST['password'])."'",$link);
}
if($row = mysql_fetch_array($sql)){
//here success
$_SESSION['objLogin'] = $row;
$_SESSION['login_type'] = $_POST['usertype'];
if($_POST['usertype'] == 'admin'){
header("Location: dashboard.php");
die();
}
else if($_POST['usertype'] == 'teacher'){
header("Location: t_dashboard.php");
die();
}
else if($_POST['usertype'] == 'student'){
header("Location: s_dashboard.php");
die();
}
else if($_POST['usertype'] == 'parents'){
header("Location: p_dashboard.php");
die();
}
else if($_POST['usertype'] == 'accountant'){
header("Location: a_dashboard.php");
die();
}
else if($_POST['usertype'] == 'librarian'){
header("Location: l_dashboard.php");
die();
}
}
else{
$msg = 'block';
}
}
function make_safe($variable)
{
$variable = strip_tags(mysql_real_escape_string(trim($variable)));
return $variable;
}
?>

This form works perfectly.
But my issue is I am creating an android form for this online version where I need a json response. So I tried the following in the browser:
mydomain.com/index.php?email=user@example.com&password=mypass&usertype=student
This results in the same page.
I am confused why this is not entering the page. I can understand that somewhere I am wrong but can't figure it out.
Kindly help please.

As @Akhil @Vijay and @MiguelJimenez suggested
I changed $_POST to $_REQUEST and it worked like a charm
So, if any one getting stuck in this issue this might help you guys hopefully.
