How to decode json data from post method for android app in php?
I am developing an application where I pass credentials and then pass it through the post method. On this page, I want to access the regno and pass value that were filled in on the login page. But I am not getting the value. I tried to iterate over values like $ data-> regno but got Null value. Please tell me what I am doing wrong.
<?php
ini_set('display_errors', '0');
error_reporting(0);
require_once("include/db.php");
class mysendclass{
public $name="Invalid";
public $priority=-1;
public $url="";
}
class myrecclass{
public $regno="";
public $pass="";
}
$e=new mysendclass();
$g=new myrecclass();
if(isset($_POST))
{
$data=json_decode(file_get_contents('php://input'));
foreach ($data AS $key => $value) $g->{$key} = $value;
$query = "SELECT priority, name, url FROM users WHERE regno='{$data->regno}' AND pass='{$data->pass}' LIMIT 1";
echo ($query);
$res = mysql_query($query, $conn) or die(mysql_error());
$found = mysql_fetch_array($res);
echo ($found);
if($found)
{
$e->name=$found['name'];
$e->priority=$found['priority'];
$e->url=$found['url'];//url
}
echo json_encode($e);
}
?>
When I submit the credentials, I get this despite posting the correct credentials from the database:
{"name":"Invalid","priority":-1,"url":""}

use this.
<?php
$abc = array();
$abc['my_first_name'] = "Suresh";
$abc['my_last_name'] = "Kumar";
echo json_encode($abc);
?>
return valid json sting -
{"my_first_name":"Suresh","my_last_name":"Kumar"}
This is a simple example for your understanding. In your request, you are encoding an object, not an array, I'm not sure but I think this is your problem try this ...
<?php
ini_set('display_errors', '0');
error_reporting(0);
require_once("include/db.php");
class mysendclass{
public $name="Invalid";
public $priority=-1;
public $url="";
}
class myrecclass{
public $regno="";
public $pass="";
}
$records = array();
$e=new mysendclass();
$g=new myrecclass();
if(isset($_POST))
{
$data=json_decode(file_get_contents('php://input'));
foreach ($data AS $key => $value) $g->{$key} = $value;
$query = "SELECT priority, name, url FROM users WHERE regno='{$data->regno}' AND pass='{$data->pass}' LIMIT 1";
echo ($query);
$res = mysql_query($query, $conn) or die(mysql_error());
$found = mysql_fetch_array($res);
echo ($found);
if($found)
{
$records['name']=$found['name'];
$records['priority']=$found['priority'];
$records['url']=$found['url'];//url
}
echo json_encode($records);
}
?>
