Question

无法在新的浏览器窗口中打开PDF。我有一个PHP代码用来设置PDF并打开它！

<?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"); 
	}

我正在尝试在新的（Chrome）浏览器窗口中打开PDF文件。

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

错误是无法加载PDF文档。

当我执行document.getElementById("edit").action ="date_PDF.php";时，它将打开pdf。

我从ftp服务器获取PDF文件，然后将其显示在date_PDF.php @readfile($ftp_path_pdf_in.$qwerty);

上

问题出在哪里？谢谢！

您尚未定义name_check html元素。另外，您尚未在网址中传递“ type”参数。我认为name_check和type存在于您打开pdf文件的页面上。

如果要使用window.open打开pdf文件，则应使用以下网址：date_PDF.php？type = in

在readfile语句之后，您应该有一个exit语句。请参见readline函数的示例：http://php.net/manual/en/function.readfile.php#refsect1-function.readfile-examples
