image uploaded by android is empty to laravel

Android is uploading image from my laravel 5.7 API but the
$request->input('image') is always on empty. I also try it using postman and its working fine. can someone help me out? XD
success result using post man form-data type
if($request->hasFile('image'))
{
$image = $request->file('image');
$name = time().'.'.$image->getClientOriginalExtension();
$destinationPath = public_path('uploads/messenger');
$image->move($destinationPath, $name);
$path = url('')."/webservices/public/uploads/messenger/".$name;
$result=[
"image_url" => $path,
];
$succes = "1";
$successMessage = "Image uploaded";
$errorMessage = "";
}
else
{
$result = (object) array();
$succes = "0";
$successMessage = "";
$errorMessage = "Image not found";
}

use Storage Facades for storing file :
create folder inside storage/app/public/uploads/messenger : with 777 permission
run command : php artisan storage:link to symlink your storage folder content available to public folder
in your controller :
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;
use Illuminate\Support\Facades\Storage;
use Carbon\Carbon;
public function upload_image(Request $request){
try{
// added validator for image field
$validator = Validator::make($request->all(), [
'image'=>'required|mimes:jpeg,jpg,png,gif|max:5120'
]);
if ($validator->fails()) {
$response=array('status'=>'error','result'=>0,'errors'=>implode(',',$validator->errors()->all()));
return response()->json($response, 200);
}else{
if($request->hasFile('image')){
$uniqueid=uniqid();
$original_name=$request->file('image')->getClientOriginalName();
$size=$request->file('image')->getSize();
$extension=$request->file('image')->getClientOriginalExtension();
$filename=Carbon::now()->format('Ymd').'_'.$uniqueid.'.'.$extension;
$imagepath=url('/storage/uploads/messenger/'.$filename);
$path=$request->file('image')->storeAs('public/uploads/messenger/',$filename);
$response=array('status'=>'success','result'=>1,'image'=>$imagepath);
return response()->json($response, 200);
}else{
$response=array('status'=>'error','result'=>0,'errors'=>'no image found');
return response()->json($response, 200);
}
}
}catch(\Exception $e){
$response=array('status'=>'error','result'=>0,'errors'=>'Internal Server Error');
return response()->json($response, 500);
}
}
add Content-Type : multipart/form-data header when uploding image from client side like android or postman

json utf-8 encoding for android

i have some persian(utf8) words on my database for my android app and i am using json for show database information in android app.
I have following code on Databasemanager.php:
function getMusics()
{
$connection = mysqli_connect(DatabaseManager::HOST_NAME, DatabaseManager::USER_NAME, DatabaseManager::PASSWORD, DatabaseManager::DATABASE_NAME);
$sqlQuery = "SELECT * FROM musics where active = 1 order by date desc;";
$result = $connection->query($sqlQuery);
$musicsArray = array();
if ($result->num_rows > 0) {
for ($i = 0; $i < $result->num_rows; $i++) {
$musicsArray[$i] = $result->fetch_assoc();
}
}
echo json_encode($musicsArray);
}
and in GetMusic.php for get json information :
<?php
include "DatabaseManager.php";
$databaseManager = new DatabaseManager();
$databaseManager->getMusics();
but i have bellow jsons on output :
{"id":"3","name":"???","artist":"????? ????","like_count":"1","comment_count":"0","dl_link":null,"photo":"http:\/\/192.168.88.6\/musicarea\/photos\/3.jpg","active":"1","date":"2017-08-04 00:00:00"}
how can i solve it ??
on output(i just use persian language at 2 last rows):
on the app:
on php my admin:

You should set the default client charset to UTF-8. Use mysqli::set_charset OR mysqli_set_charset.
See http://de2.php.net/manual/en/mysqli.set-charset.php for more info.

You have to add the header that it tells the client the response is encoding with utf-8
header('Content-Type: text/html; charset=utf-8');

EDIT
function getMusics()
{
$connection = mysqli_connect(DatabaseManager::HOST_NAME, DatabaseManager::USER_NAME, DatabaseManager::PASSWORD, DatabaseManager::DATABASE_NAME);
$sqlQuery = "SELECT * FROM musics where active = 1 order by date desc;";
$result = $connection->query($sqlQuery);
$musicsArray = array();
if ($result->num_rows > 0) {
for ($i = 0; $i < $result->num_rows; $i++) {
$musicsArray[$i] = $result->fetch_assoc();
}
}
header("Content-type: application/json; charset=utf-8");
echo json_encode($musicsArray);
}

white thumbnail for uploaded video in android app

I am making api's for my android app using Slim framework.But when i upload video to local server from my android app by calling api,it generates white thumbnail for video in my app.How can i get the thumbnail for the uploaded video.
My code for making api is:
$app->post('/do_upload', 'authentication', function () use ($app) {
verifyRequiredParams(array('albumId'));
global $user_id;
$response = array();
$file_path = "../uploads/$user_id/photo_gallery/thumbnails/";
if (!file_exists($file_path)) {
mkdir($file_path, 0777, true);
}
$thumbnail = $user_id . "/photo_gallery/thumbnails/";
$response = array();
if (isset($_FILES["files"])) {
$temp = explode(".", $_FILES['files']['name']);
$detectedType = $_FILES["files"]["name"];
$filetype = substr($detectedType, strpos($detectedType, ".") + 1);
$newfilename = 'shared_' . rand(1, 99999) . '.' . end($temp);
$file_path = $file_path . basename($newfilename);
$thumbnail = "$user_id/photo_gallery/thumbnails/" . $newfilename;
$filename = "$user_id/photo_gallery/thumbnails/" . $newfilename;
$mobile_thumbnail = "$user_id/photo_gallery/thumbnails/" . $newfilename;
if (move_uploaded_file($_FILES['files']['tmp_name'], $file_path)) {
}
$albumId = urldecode($app->request->post('albumId'));
$caption = urldecode($app->request->post('caption'));
$db = new DbHandler();
if (($filetype == "gif")
|| ($filetype == "png")
|| ($filetype == "jpeg")
|| ($filetype == "jpg")
|| ($filetype == "JPEG")
|| ($filetype == "PNG")
|| ($filetype == "GIF")
|| ($filetype == "JPG")
) {
$type = "image";
$result = $db->SharedImage($albumId, $user_id, $caption, $filename, $thumbnail, $mobile_thumbnail, $type);
} else {
$type = "video";
$result = $db->SharedImage($albumId, $user_id, $caption, $filename, $thumbnail, $mobile_thumbnail, $type);
}
if ($result != "null") {
while ($res = $result->fetch_assoc()) {
$response = array();
$response["id"] = $res["id"];
$response["event_id"] = $res["event_id"];
$response["album_id"] = $res["album_id"];
$response["status"] = $res["status"];
$response["filename"] = $res["filename"];

$response["taken"] = $res["taken"];
$response["copied_from"] = $res["copied_from"];
$response["media_size"] = $res["media_size"];
$response["thumbnail_size"] = $res["thumbnail_size"];
echoRespnse(200, $response);
}
} else {
$response["message"] = "response contain no data";
echoRespnse(200, $response["message"]);
}
} else {
$response ["error"] = true;
$response ["message"] = "Please select a file to upload";
echoRespnse(200, $response);
}
});
Please tell me why the thumbnail of video uploded is white and how can i get the video cover.

Using ffmpeg ,My problem was solved.Here is the code exec('ffmpeg -y -i '.$file_path.' -vcodec mjpeg -ss 00:00:01 -vframes 1 -an -s 620x440 -f rawvideo '.$image.'',$thumb_stdout, $retval);
This created a thumbnail at path $image of size 620*440.

how to extract jsonarray in java when two arrays in output

How to retrieve the ids array from the following JSON Object.
{"bets":[{"bet":[{"gid":"10","Result":null}]},{"bet":[{"gid":"7","Result":null}]},{"bet":[{"gid":"3","Result":null},{"gid":"6","Result":"2"}]},{"bet":[{"gid":"6","Result":"2"},{"gid":"4","Result":"1"}]},{"bet":[{"gid":"6","Result":"2"},{"gid":"4","Result":"1"}]}]}{"ids":["9c9nogs6of","ank4kt3gqo","jfgrt91nk4","a8qmoq7v4q","8mov5ita1t"]}
I've tried
allids = jObj.getJSONArray("ids");
which should work because it works with jObj.getJSONArray("bets"); however I receive this error in logcat E/Buffer Error﹕ Error converting result org.json.JSONException: No value for ids
PHP FILE
<?php
// get tag
$param= $_POST['param'];
$bet = explode("//",$param);
$allbetslength = count($bet);
$ultresponse["bets"] = array();
$idresponse["ids"] = array();
for ($x = 0; $x < $allbetslength; $x++) {
$indid = substr($bet[$x],0,10);
array_push($idresponse["ids"], $indid);
$bet[$x] = substr($bet[$x],10);
$id = explode(",",$bet[$x]);
$arrlength = count($id);
// include db handler
require_once 'include/Check_Bets.php';
$db = new Check_Bets();
$response["bet"] = array();
for($y = 0; $y < $arrlength; $y++) {
$result= $db->checkuserbets($id[$y]);
array_push($response["bet"], $result);
}
array_push($ultresponse["bets"], $response);
array_push($ultresponse["bets"], $idresponse["ids"]);
}
echo json_encode($ultresponse);
?>

Titanium Alloy Android Login

I am having an issue with a Titanium App, the issue is only with Android, iOS is fine.
So I have a login form that queries the database, pretty straightforward. But for some reason it is not passing the params to the login script.
My JS function in app, have set the alert on the else statement to print out the $.email.value and password values which read fine. But with the current $response which is just a json it shows the values as being blank? The php form is also below. As I have said this is working fine on iOS
function login(e) {
//function to use HTTP to connect to a web server and transfer the data.
var sendit = Ti.Network.createHTTPClient({
onerror : function(e) {
Ti.API.debug(e.error);
alert('There was an error during the connection');
},
timeout : 100000,
});
//Here you have to change it for your local ip
sendit.open('GET', 'http://soyo.taylorhoganit.co.uk/post_auth.php');
var params = {
email : $.email.value,
password : $.password.value,
};
sendit.send(params);
//Function to be called upon a successful response
sendit.onload = function() {
var json = this.responseText;
var response = JSON.parse(json);
if (response.logged == true)
{
var landing = Alloy.createController("landing").getView();
$.index.close();
landing.open();
// Ti.App.Properties.setString('email', $.email.value);
// Ti.App.Properties.setString('password', $.password.value);
//alert("Username: " + response.username);
}
else
{
alert($response);
}
};
};
PHP Script
<?php
// Connect to the database(host, username, password)
$con = mysql_connect('replaced values');
if (!$con)
{
echo "Failed to make connection.";
exit;
}
$db = mysql_select_db('soyo');
if (!$db)
{
echo "Failed to select db.";
exit;
}
$email = $_POST['email'];
$password = $_POST['password'];
$sql = "SELECT * FROM users WHERE email = '" . $email . "' AND password = '" . $password . "'";
$query = mysql_query($sql);
// If we find a match, create an array of data, json_encode it and echo it out
if (mysql_num_rows($query) > 0)
{
$row = mysql_fetch_array($query);
$response = array(
'logged' => true,
'email' => $row['email']
);
echo json_encode($response);
}
else
{
// Else the username and/or password was invalid! Create an array, json_encode it and echo it out
$response = array(
'logged' => false,
'message' => $email + $password
);
echo json_encode($response);
}
?>

You did a mistake by using $response in the alert. It is a PHP variable not JS.
var response = JSON.parse(json);
// ...
alert($response); // Here should be just `response`
Edit: The another problem is that you are sending GET request while in PHP you accept POST ,so you can't get any params...

There is a mistake when you want to show alert.
You are using now is alert($response);
Remove $ from $response and use alert(response);, it will work properly.
