下载表格的pdf文件，并将数据保存在数据库服务器中

Question

我需要知道如何在数据库中保存数据并同时下载它的pdf文件。我已经分别完成了这两个任务，但现在我需要一起执行这两项任务。我现在的代码只是保存数据库中的数据而不下载它的pdf文件 这是代码

$connection = mysql_connect('localhost', 'sujdhuj', 'msRQT0g(pqbX');
mysql_select_db('sujdhuj_dawoodDB',$connection);
if(!$connection){
    die("connection failed:" .mysqli_connect_error());
}
echo "connection hogya successful";
$Sno= $_POST['Sno'];
$Clientname= $_POST['Clientname'];
$Contactno = $_POST['Contactno'];
$Dos= $_POST['Dos'];
$Start= $_POST['Start'];
$End= $_POST['End'];
$Dow= $_POST['Dow'];
$Location= $_POST['Location'];
$Osi= $_POST['Osi'];
$Emhr= $_POST['Emhr'];
$Er= $_POST['Er'];
$Mir= $_POST['Mir'];
$Ea= $_POST['Ea'];
$Cr= $_POST['Cr'];
$Mir1= $_POST['Mir1'];
$Am= $_POST['Am'];
$Ca= $_POST['Ca'];
$Date= $_POST['date'];
$check= $_POST['option_3'];

//$Image= $_Post['image'];

$sql= "INSERT INTO surveyform(Sno, Clientname, Contactno, Dos, Start, End, Dow, Osi, Emhr,    Er,  Mir,    Ea,   Cr,    Mir1,    Am,   Ca,   Date, image) 
 VALUES('$Sno', '$Clientname', '$Contactno', '$Dos','$Start', '$End', '$Dow', '$Osi', '$Emhr', '$Er','$Mir', '$Ea', '$Cr', '$Mir1', '$Am', '$Ca', '$Date' ,'$Image')";

    if(!mysql_query($sql))
    {
        die('caution record not added' . mysql_error());
    }
        echo"1 record added";
