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);

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;
