Question

我正在一个项目中，我正在其中显示目录中的文件。当用户单击某一行时，它将调用另一个PHP文件，并在其中下载PDF文件，并显示其他代码。当前，当我单击链接时，只有文件正在下载，而我看不到PHP页面。我在做什么错了？

用例：下载的PDF将由用户填写，然后再次上传。.上传和进一步处理的代码位于send-mail.php中。因此，我需要下载文件并将用户也发送到send-mail.php。那是用例。

发生重定向的原始PHP：

<?php
    echo "<table  align='center' class='loopblock'>";
    echo "<tr>
    <th>Existing templates</th>
    </tr>";    
    $path = "/var/www/html/pdf/";
    $files = scandir($path);
    $files = array_diff(scandir($path), array('.', '..'));
    foreach($files as $key){
    echo"<tr class='loop'>
        <td class='click' align='center' width='500' class='loop'><a class='loop' align='center'
          href='/send-email.php?fileName=$key'>$key</a></td>                        
        </a>    
        </tr>";     
    }       
    echo"</table>";
?>

send-email.php：当下面的PHP代码存在时，我看不到HTML代码。

<div class="container">
        <div class="contr"><h2>Drag and Drop your Tempalates to 'Drop Area' (size - under 10Mb)</h2></div>
        <div class="upload_form_cont">
            <div id="dropArea">Drop Area</div>
            <div class="info">
                <div>Files left: <span id="count">0</span></div>
                <div>Destination url: <input id="url" value="/upload.php" readonly/></div>
                <h2>Result:</h2>
                <div id="result"></div>
            <canvas width="500" height="20"></canvas>
            </div>
        </div>
</div>
<script src="js/script.js"></script>
<?php
    ignore_user_abort(true);
    set_time_limit(0); // disable the time limit for this script

    $path = "/var/www/html/pdf/"; // change the path to fit your websites document structure

    $dl_file = preg_replace("([^\w\s\d\-_~,;:\[\]\(\).]|[\.]{2,})", '', $_GET['fileName']); // simple file name validation
    $dl_file = filter_var($dl_file, FILTER_SANITIZE_URL); // Remove (more) invalid characters
    $fullPath = $path.$dl_file;

    if ($fd = fopen ($fullPath, "r")) {
        $fsize = filesize($fullPath);
        $path_parts = pathinfo($fullPath);
        $ext = strtolower($path_parts["extension"]);
        switch ($ext) {
            case "pdf":
            header("Content-type: application/pdf");
            header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\""); // use 'attachment' to force a file download
            break;
            // add more headers for other content types here
            default;
            header("Content-type: application/octet-stream");
            header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
            break;
        }
        header("Content-length: $fsize");
        header("Cache-control: private"); //use this to open files directly
        while(!feof($fd)) {
            $buffer = fread($fd, 2048);
            echo $buffer;
        }
    }
    fclose ($fd);
?>

任何想法我可能做错了什么？谢谢。

更新

将其更改为以下内容：

<div class="container">
        <div class="contr"><h2>Drag and Drop your Tempalates to 'Drop Area' (size - under 10Mb)</h2></div>
        <div class="upload_form_cont">
            <div id="dropArea">Drop Area</div>
            <div class="info">
                <div>Files left: <span id="count">0</span></div>
                <div>Destination url: <input id="url" value="/upload.php" readonly/></div>
                <h2>Result:</h2>
                <div id="result"></div>
            <canvas width="500" height="20"></canvas>

    $fullPath = $path.$dl_file;

    if ($fd = fopen ($fullPath, "r")) {
        $fsize = filesize($fullPath);
        $path_parts = pathinfo($fullPath);
        $ext = strtolower($path_parts["extension"]);
        switch ($ext) {

            echo $buffer;
        }
        fclose ($fd);
        exit();
    }
?> 
</body>
</html>

我终于结束了添加此操作以解决问题：

<?php
$invite = $_GET['fileName'];
echo '<META HTTP-EQUIV="Refresh" Content="0; URL=download_pdf.php?fileName=' . $invite . '">'; 
?>

PHP：使TD可单击并为其添加附加参数
