Question

大家好我正在制作一个Android应用程序，使用php在mysql数据库中上传图像并且工作正常。应用程序将图像成功上传到数据库但问题是我只能上传更小尺寸的图像只能用kbs.I想要它以mbs上传图像。我尝试外翻但直到现在都没有用。有人帮我... 我在php上传图片的代码是：

 <?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";
}
?>

我上传图片的android活动是：

  import android.app.ProgressDialog;

            String phoneNumber = et2.getText().toString();
            String price = et3.getText().toString();

            HashMap<String, String> data = new HashMap<>();
            data.put(UPLOAD_KEY, uploadImage);

            data.put(Fetch.BOOK_NAME, bookname);

            String result = rh.sendPostRequest(UPLOAD_URL, data);

您存储base64的列的数据类型是什么？尝试文本或blob ..也许文本太长，数据类型无法处理。只猜测
