尝试在新的浏览器窗口中打开pdf文件

Cant get the PDF open in new browser window. There is a php code I use to set the PDF and open it!

<?php
if (($_POST['name_check']=="in") || ($_GET['type']=="in")){
    header('Content-Type: application/pdf; charset=windows-1257');
    header("Content-Disposition: inline; ");
    header('Accept-Ranges: bytes');
    $file_type = "in";
    $flag = 0;
}
else{
    header('Content-Type: application/pdf; charset=windows-1257');
    header("Content-Disposition: inline;");
    header('Accept-Ranges: bytes');
    $file_type = "out";
    $flag = 1;
}

?>
<?php session_start();   
    if (((isset($_SESSION['UserID'])) and (isset($_SESSION['Pin_code']))) and (isset($_COOKIE['CookieMy']))){
        $form='<form action="login.php" method="get" style="width: 900px;margin: -1px auto -57px auto;" class="exit_but">
        <input type="submit" name="exit" value="EXIT" style="margin-left: 800px;"></form>';
        echo $form;         
    } else {
        header("Location: login.php"); 
    }
?>

I'm trying to open PDF file in the new (Chrome) browser window.

document.action =window.open('date_PDF.php', 'newWindow', 'width=1000, height=1000');

Error is Failed to load PDF document.

When I do document.getElementById("edit").action ="date_PDF.php"; it opens pdf.

I get the PDF file from the ftp server and than display it on date_PDF.php @readfile($ftp_path_pdf_in.$qwerty);

Where is the problem? Thank you!

    You have not defined the name_check html element. Also you have not passed the 'type' parameter in the url. I think the name_check and type are present on the page from where you open the pdf file.

    If you want to open the pdf file using window.open then you should use the url: date_PDF.php?type=in

    After the readfile statement you should have an exit statement. See the example for the readline function: http://php.net/manual/en/function.readfile.php#refsect1-function.readfile-examples
