doforumda Posted June 2, 2012 Share Posted June 2, 2012 I am trying to make json data in php using json_encode() function. Then I will use this data on the client side. I acheived some of the part. My current code displays json data in this format { "data": { "tag":"home", "success":1, "error":0, "uid":"4fc8f94f1a51c5.32653037", "name":"Zafar Saleem", "profile_photo":"http:\/\/example.info\/android\/profile_photos\/profile1.jpg", "places": { "place_photo":"http:\/\/example.info\/android\/places_photos\/place1.jpg", "created_at":"2012-06-02 00:00:00", "seeked":"0" } } } { "data": { "tag":"home", "success":1, "error":0, "uid":"4fc9c413554104.22444656", "name":"Name", "profile_photo":"http:\/\/example.info\/android\/profile_photos\/profile2.jpg", "places": { "place_photo":"http:\/\/example.info\/android\/places_photos\/place2.jpg", "created_at":"2012-06-03 00:00:00", "seeked":"0" } } } { "data": { "tag":"home", "success":1, "error":0, "uid":"4fc9c48c529675.45551665", "name":"Name", "profile_photo":"http:\/\/example.info\/android\/profile_photos\/profile3.jpg", "places": { "place_photo":"http:\/\/example.info\/android\/places_photos\/place3.jpg", "created_at":"2012-06-04 00:00:00", "seeked":"20" } } } what I want to show above data in this form { "data": [ { "tag":"home", "success":1, "error":0, "uid":"4fc8f94f1a51c5.32653037", "name":"Zafar Saleem", "profile_photo":"http:\/\/example.info\/android\/profile_photos\/profile1.jpg", "places": { "place_photo":"http:\/\/example.info\/android\/places_photos\/place1.jpg", "created_at":"2012-06-02 00:00:00", "seeked":"0" } }, { "tag":"home", "success":1, "error":0, "uid":"4fc9c413554104.22444656", "name":"Name", "profile_photo":"http:\/\/example.info\/android\/profile_photos\/profile2.jpg", "places": { "place_photo":"http:\/\/example.info\/android\/places_photos\/place2.jpg", "created_at":"2012-06-03 00:00:00", "seeked":"0" } }, { "tag":"home", "success":1, "error":0, "uid":"4fc9c48c529675.45551665", "name":"Name", "profile_photo":"http:\/\/example.info\/android\/profile_photos\/profile3.jpg", "places": { "place_photo":"http:\/\/example.info\/android\/places_photos\/place3.jpg", "created_at":"2012-06-04 00:00:00", "seeked":"20" } } ] } here is my php code that generates json data database function that gets data from database public function getHome() { $result = mysql_query("SELECT * FROM places") or die(mysql_error()); // check for result $no_of_rows = mysql_num_rows($result); if ($no_of_rows > 0) { while($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $data[] = $row; } return $data; /* $result = mysql_fetch_array($result); return $result; */ } else { // user not found return false; } } here is where I make json on php if($db->getHome()) { $data = $db->getHome(); foreach($data as $r) { $response['success'] = 1; $response['uid'] = $r['uid']; $response['name'] = $r['name']; $response['profile_photo'] = $r['profile_photo_path']; $response['places']['place_photo'] = $r['place_photo_path']; $response['places']['latitude'] = $r['latitude']; $response['places']['longitude'] = $r['longitude']; $response['places']['created_at'] = $r['created_at']; $response['places']['seeked'] = $r['total_completed']; echo json_encode(array('data' => $response)); } } else { $response['error'] = 1; $response['error_msg'] = 'No data available'; echo json_encode($response); } Quote Link to comment Share on other sites More sharing options...
smoseley Posted June 2, 2012 Share Posted June 2, 2012 if($db->getHome()) { $data = $db->getHome(); $response = array('data' => array()); foreach($data as $r) { array_push($response['data'], array( 'success' => 1, 'uid' => $r['uid'], 'name' => $r['name'], 'profile_photo' => $r['profile_photo_path'], 'places' => array( 'place_photo' => $r['place_photo_path'], 'latitude' => $r['latitude'], 'longitude' => $r['longitude'], 'created_at' => $r['created_at'], 'seeked' => $r['total_completed'], ) )); } } else { $response = array('error' => 1, 'error_msg' => 'No data available'); } echo json_encode($response); Quote Link to comment Share on other sites More sharing options...
smoseley Posted June 2, 2012 Share Posted June 2, 2012 By the way... this is HORRIBLY inefficient... will execute your query twice: if($db->getHome()) { $data = $db->getHome(); Instead, do this... so you execute your query only once: $data = $db->getHome(); if(!empty($data)) { Cheers Quote Link to comment Share on other sites More sharing options...
