Fatal error: Call to a member function bind_param () on boolean

I am creating an android application that communicates with the web service in order to add data to mysql. When executing the code, the application sends some data and expects a response from the server, the server is responsible for saving the images sent from the application on the same server, sending other data to the database and returning a response to the application, but the server only he manages to save the photos on the server and he can not upload the other data to the database and he returns an error response:

  

Fatal error: Call to a member function bind_param () on boolean

this is my server php code:

 <?PHP
    $hostname_localhost="localhost";
    $database_localhost="photogo";
    $username_localhost="root";
    $password_localhost="Root1234";
    $con=mysqli_connect($hostname_localhost,$username_localhost,$password_localhost,$database_localhost);
        $u_name = $_POST["u_name"];
        $localname = $_POST["localname"];
        $zone = $_POST["zone"];
        $category = $_POST["category"];
        $latitude = $_POST["latitude"];
        $logitude = $_POST["longitude"];
        $comment = $_POST["comment"];
        $image = $_POST["image"];
        $date="".date("Y-m-d H:i:s")."";
        $name=$u_name."_".date("d_m_Y_H_i_s").".jpg";


        $path = "images/".$name;
        //$url = "http://$hostname_localhost/ejemploBDRemota/$path";
        $url = "images/".$name;
        file_put_contents($path,base64_decode($image));
        $bytesFiles=file_get_contents($path);
        $sql="INSERT INTO dataimage VALUES(?,?,?,?,?,?,?,?,?,?)";

        $stm=$con->prepare($sql);

        $stm->bind_param('ssssssddss',$bytesFiles,$url,$u_name,$localname,$zone,$category,$latitude,$logitude,$comment,$date);

        if($stm->execute()){
            echo "register";
        }else{
            echo "noRegister";
        }

        mysqli_close($con);
