圖片在android中使用php上傳大小為0字節

Question

我正在制作一個Android應用程序，使用php上傳mysql數據庫中的圖像。 即時通訊保存在目錄[$ path =“ uploads / $ id.png”; $ actualpath =“ http://www.bsservicess.com/photoUpload/ $ path”]。

問題是圖像正在上載到目錄，但是圖像的大小顯示為0字節。 我不知道是什么問題。它工作得很早，但我不知道為什么它現在上傳0字節的圖像大小。 我嘗試了一切但沒有任何作用。 如果有人知道解決方案，請幫助我。

 <?php 
 if($_SERVER['REQUEST_METHOD']=='POST'){

    $photo= $_POST['photo'];
    $bookname=$_POST['bookname'];
            $phoneNumber=$_POST['phoneNumber'];
            $price=$_POST['price'];

    require_once('loginConnect.php');

    $sql ="SELECT id FROM images ORDER BY id ASC";

    $res = mysqli_query($con,$sql);

    $id = 0;

    while($row = mysqli_fetch_array($res)){
            $id = $row['id'];
    }

    $path = "uploads/$id.png";

    $actualpath = "http://www.bsservicess.com/photoUpload/$path";

    $sql = "INSERT INTO images (photo,bookname,phoneNumber,price) VALUES
     ('$actualpath','$bookname','$phoneNumber','$price')";

    if(mysqli_query($con,$sql)){
        file_put_contents($path,base64_decode($photo));
        echo "Successfully Uploaded";
    }

    mysqli_close($con);
  }else{
    echo "Error";
 }

您可以仔細檢查您的代碼嗎？ 您的$photo永遠不會使用，並且您嘗試解碼的$image也為null。
