彈出要下載的文件，點擊鏈接

Question

我試圖讓.txt，.xml，.sql文件可以在同一頁面下載，就像.zip，.docx文件一樣彈出並詢問「你想下載這個文件嗎？「。 我研究並發現，這些文件的Windows默認選項在新瀏覽器中打開，但我只想在同一頁面下載。我附加了圖片，就像點擊那些.txt，.xml，.sql文件時需要彈出的圖片一樣。 這怎麼辦？任何人都有這個想法。

 I have corrected by my own. Just putting the code below will successfully pop up any files to ask whether to download or not. This is my new code. 
    The download.php contains the code below: 

     <?php 
     $filename = $_GET["file"]; 
     $contenttype = "application/force-download"; 
     header("Content-Type: " . $contenttype); 
     header("Content-Disposition: attachment; filename=\"" . basename($filename) . "\";"); 
     if($_GET['path'] == 'new_uploads') 
     readfile($_SERVER['DOCUMENT_ROOT']."50dl/admin_panel_new/assets/plupload/new_uploads/".$filename); 
     else 
     readfile($_SERVER['DOCUMENT_ROOT']."50dl/admin_panel_new/assets/plupload/assessment_uploads/".$filename); 
     exit(); 
     ?> 

And the file.php contains this code: 

<img src="<?php echo base_url();?>assets/plupload/assessment_uploads/<?php echo $files->file_name?>" title="DOWNLOAD IMAGE" height="100" width="100" onClick="window.location.href='<?php echo base_url();?>logos/download?file=<?php echo $files->file_name?>&path=assessment_uploads'" class="download"/> 

This will correctly sort out the current issue.

你應該通過在要求的文件下載代碼的標頭。

$task = isset($_REQUEST['task']) ? $_REQUEST['task'] : ''; 
if ($task == 'download'){ 
    header('Content-Description: File Transfer'); 
    header('Content-Type: application/octet-stream'); 
    header('Content-Disposition: attachment; filename='.basename($_REQUEST['file_name'])); 
    header('Content-Transfer-Encoding: binary'); 
    header('Expires: 0'); 
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); 
    header('Pragma: public'); 
    header('Content-Length: ' . filesize($_REQUEST['file_name'])); 
    ob_clean(); 
    flush(); 
    readfile($_REQUEST['file_name']); 
    exit;}

You can use this and it will work like a charm . 
<?php 
     $filename = $_GET["file"]; 
     $contenttype = "application/force-download"; 
     header("Content-Type: " . $contenttype); 
     header("Content-Disposition: attachment; filename=\"" . basename($filename) . "\";"); 
     if($_GET['path'] == 'new_uploads') 
     readfile($_SERVER['DOCUMENT_ROOT']."50dl/admin_panel_new/assets/plupload/new_uploads/".$filename); 
     else 
     readfile($_SERVER['DOCUMENT_ROOT']."50dl/admin_panel_new/assets/plupload/assessment_uploads/".$filename); 
     exit(); 
     ?>
