how to redirect php page with parameters into new tab or window

javascript, php, redirect

Solution

The php header should be :

header("location:Delivery_form.php?cnno=".$cnno."&copies=".$nocopy);

Script

echo "<script type=\"text/javascript\">
        window.open('Delivery_form.php?cnno=".$cnno."&copies=".$nocopy."', '_blank')
    </script>";

Problem

I have print option in my application. When user click on print button the print page should be open in another tab/window. Again I am sending some parameters with print page as it contain dynamic values. to do so i have used php header as ``` header("location:Delivery_form.php?cnno=$cnno&copies='$nocopy'"); ``` but it is redirecting in parent page. and javascript window.open as ``` echo "<script type=\"text/javascript\">". "window.open('Delivery_form.php?cnno='".$cnno."&copies=".$nocopy ")". "</script>"; ``` please help me to achieve this funcnality.
