When we are about take a picture the camera output is displayed on the screen. 
How do we take a snap without displaying the camera output on the webpage?

In HTML File either remove hook for on Completion
I mean remove or comment this
webcam.set_hook( 'onComplete', 'my_completion_handler' );

or remove code from my_completion_handler() javascript function to not show 
image

The way this code works and starts the webcam and takes the picture and
allows for saving the image, do you by any chance hav a similar code for
fingerprint reader. I want a code that starts the fingerprint reader when a
page is loaded and allows for saving the fingerprint on the click event of a
button.

This is my code for test.php
<?php

    $fname = $_POST['txtFname'];
    $lname = $_POST['txtLname'];
    $pno = $_POST['txtUname'];
    $pwd = $_POST['txtPwd'];
    $rpwd =$_POST['rtxtPwd'];

    $grade = $_POST['txtgrade'];

    $des=$_POST['desig'];
    $dep=$_POST['select'];
    $gender=$_POST['rad1'];

    $dateOB=isset($_REQUEST["date1"]) ? $_REQUEST["date1"] : "";
    $dateOJ=isset($_REQUEST["date2"]) ? $_REQUEST["date2"] : "";

$filename = 'Employee_pics/'.$_POST['txtUname'].date('YmdHis') . '.jpg';

if(!is_numeric($pno))
    {
        echo "Invalid Personal Number";
    }
    else if($pwd !== $rpwd)
    {
        echo "Password not Match";
    }
    else
    {
        // encrypting the password //
        //$pwd = md5($pwd);

        // connecting to database //
        $host="localhost"; // Host name
$user="root"; // Mysql username
$pass=""; // Mysql password
$db_name="hospital"; // Database name
$tbl_name="personal_table"; // Table name
// Connect to server and select databse.
$con = mysql_connect("localhost","root");
if (!$con)
{
die('Could not connect: ' . mysql_error());

mysql_select_db("$db_name")or die("cannot select DB");
        // checking username existance //

                        $result=mysql_query("select * from $tbl_name where pno=$pno");

        //$result = mysql_query($sql,$con);
        if($count==0)
        {

            // inserting user into tbl_user //
                    $sql1 = "insert into $tbl_name (pno, desig, grade, fname, lname, dob, dept, password, doj, gender, img ) values('$pno','$des','$grade','$fname','$lname','$dateOB','$dep','$pwd','$dateOJ','$gender','$filename')";

                                    }

                        else
                                {

                                    $result = file_put_contents( $filename, file_get_contents('php://input') );
                                    $url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['REQUEST_URI']) . '/' . $filename;
print "$url\n";
if (!$result) {
    print "ERROR: Failed to write data to $filename, check permissions\n";
    exit();
}
                                    }

        }       

        else
        {           

                    echo "Pno already exists.";

        }
