Self submitting form, then refresh page?

Question

I have a page in PHP with a form that contains multiple checkmarks. These checkmarks can be used to either DELETE the records or create LABELS for whatever is selected.

I got the delete section going just fine as I use the same page ($_SERVER['PHP_SELF']) to run a query, but the labels isn't working because I need to pass the values to another page called PDF_Label_Print.php. I would like to stay away from session variables if possible.

The page works, but sometimes it doesn't refresh automatically. Any ideas? Thanks!

if (isset($_GET['labels']) && (is_array($news_ids) && count($news_ids) > 0))
{
    $label_list  = implode(',', $news_ids);
    echo "<form action='PDF_Label_Print.php' method='post' name='frm' target='_blank'>
    <input type='hidden' name='full_list' value='". htmlentities(serialize($label_list)) ."' />
    <input type='hidden' name='tbl_name' value='" . $_SESSION['officeid'] ."' />
    <input type='hidden' name='report' value='list' />
    <input type='hidden' name='avery' value='5160' />
    </form>";

    echo "<script language='JavaScript'>document.frm.submit();</script>";
    // refresh page.

    echo '<script language="javascript">window.location = "welcome.php"</script>';
}

Answer 1

the problem is that after submitting a form javascript might stop working till the post is done, and the form action is another page.BUT again, when submitting a form (without ajax) the page should refresh automatically.

So what you need is on the PDF_Label_Print.php page to redirect back to the welcome page

header("location:welcome.php"); // or anyother page you want to redirect after posting

Thank you for everyone who took to their time to look at my question.

Turns out I was able to resolve the issue by using POST instead of GET on my form. The header location is now refreshing the page correctly.
