Question

我创建的数据库有2个字段名和路径文件名作为dwm.pdf和路径为C：\ XAMPP \ htdocs中\ P1 \测试。我只是想显示的链接点击与路店的数据库帮助PDF文件。

<?php
$con = mysqli_connect("localhost","root","billa","pdf_trial") or die
("Couldn't connect");
echo "Connected";
$q = "SELECT path FROM pdffiles WHERE filename =dwm"
$r = mysqli_query($q);
$row = mysqli_fetch_assoc($r);
header('Content-type: application/pdf');

?>

我想通过访问，我在mysql中已经存储路径显示在网页的PDF文件。我怎么能做到这一点

Answer 1

您可以访问它从用$row['path']然后再输出readfile() PDF文件中的数据库中检索的路径：

<?php
$con = mysqli_connect("localhost","root","billa","pdf_trial") or die("Couldn't connect to MySQL");
$q = "SELECT path FROM pdffiles WHERE filename = 'dwm'"
$r = mysqli_query($q);
$row = mysqli_fetch_assoc($r);
header('Content-type: application/pdf');
readfile($row['path']);

使用iframe链接您的PDF

<iframe src="http://docs.google.com/gview?url=http://path.com/to/your/pdf.pdf&embedded=true" 
style="width:600px; height:500px;" frameborder="0"></iframe>
