Php JSON Response Array - php

Question

I have this php code. As you can see i query a mysql database through a function showallevents. I return a the $result to the $event variable. With the while loop i assign the values that i get from event to a response array and every time the loop happens the rows are stored in the data array. Surely i am failing somewhere because despite i am getting a correct number of responses all the values that i get at json are "null". Also it tells me something about JSONarray cannot be converted to jsonobject
if (isset($_POST['tag']) && $_POST['tag'] != '')
{
// get tag
$tag = $_POST['tag'];
// include db handler
require_once 'include/DB_Functions.php';
$db = new DB_Functions();
// response Array
$response = array("tag" => $tag, "success" => 0, "error" => 0);
// check for tag type
if ($tag == 'showallevents')
{
// Request type is show all events
// show all events
$event = $db->showallevents();
if ($event != false)
{
$data = array();
while($row = mysql_fetch_assoc($event))
{
$response["success"] = 1;
$response["uid"] = $event["uid"];
$response["event"]["date"] = $event["date"];
$response["event"]["hours"] = $event["hours"];
$response["event"]["store_name"] = $event["store_name"];
$response["event"]["event_information"] = $event["event_information"];
$response["event"]["event_type"] = $event["event_type"];
$response["event"]["Phone"] = $event["Phone"];
$response["event"]["address"] = $event["address"];
$response["event"]["created_at"] = $event["created_at"];
$response["event"]["updated_at"] = $event["updated_at"];
$data[]=$response;
}
echo json_encode($data);
}
else
{
// event not found
// echo json with error = 1
$response["error"] = 1;
$response["error_msg"] = "Events not found";
echo json_encode($response);
}
}
else
{
echo "Access Denied";
}
}
?>
the DB_Functions.php
<?php
class DB_Functions
{
private $db;
//put your code here
// constructor
function __construct()
{
require_once 'DB_Connect.php';
// connecting to database
$this->db = new DB_Connect();
$this->db->connect();
}
// destructor
function __destruct()
{
}
/**
* Select all events that are after yesterday.
*/
public function showallevents()
{
$result = mysql_query("SELECT * FROM events WHERE date >= CURDATE()");
return($result);
}
}
?>
ok the code that helped me put all data into an array was this
$data = array();
while($row = mysql_fetch_assoc($event))
{
$response["success"] = 1;
$response["event"]= $row;
$data[]=$response;
}
echo json_encode($data);

Answer 1

You've merged two independent pieces of code and wound up with a mess whose result is unclear.
You can create an associative array in two ways:
$array = (key=>value, key2=>value2);
You can also use:
$array[key]=value;
$array[key2]=value2;
Note that both 'key' and 'value' are simply variables; you can use strings there, or pass in a variable from someplace else.
When doing similar things, I use the following approach:
$response["success"] = 1;
$response["uid"] = $event["uid"];
$response["event"]["date"] = $event["date"];
$response["event"]["hours"] = $event["hours"];
$response["event"]["store_name"] = $event["store_name"];
$response["event"]["event_information"] = $event["event_information"];
$response["event"]["event_type"] = $event["event_type"];
$response["event"]["Phone"] = $event["Phone"];
$response["event"]["address"] = $event["address"];
$response["event"]["created_at"] = $event["created_at"];
$response["event"]["updated_at"] = $event["updated_at"];
$data[]=$response;

Answer 2

What is your $response variable?
In PHP to create associative arrays, you use => and not =
for example:
$array = ('key1' => 'value1', 'key2' => 'value2');

Answer 3

if you just want to return all the arrays, can you use mysql_fetch_assoc in stead of mysql_fetch_row?
if ($tag == 'showallevents')
{
// Request type is show all events
// show all events
$event = $db->showallevents();
if ($event != false)
{
$data = array();
while($row = mysql_fetch_assoc($event))
{
$data[] = $row;
echo json_encode($data);
}
else
{
// event not found
// echo json with error = 1
$response["error"] = 1;
$response["error_msg"] = "Events not found";
echo json_encode($response);
}
}
else
{
echo "Access Denied";
}
}
