上载Word文档以创建文件下载（PHP）

Question

I am doing a school project where students can upload study notes to help other students. I have created the ability to upload word/pages files but I want to enable that once the file is uploaded, other users can click on that file and it will download for them.

Not really sure what code to put.. (This is upload.php)

if ($_SERVER['REQUEST_METHOD'] == 'POST') {

        $name     = $_FILES['file']['name'];
        $tmpName  = $_FILES['file']['tmp_name'];
        $error    = $_FILES['file']['error'];
        $size     = $_FILES['file']['size'];
        $ext      = strtolower(pathinfo($name, PATHINFO_EXTENSION));

        switch ($error) {
            case UPLOAD_ERR_OK:
                $valid = true;
                //validate file extensions
                if ( !in_array($ext, array('jpg','jpeg','png','gif', 'docx', 'mp3')) ) {
                    $valid = false;
                    $response = 'Invalid file extension.';
                }

And this is where the files go (files.php)

<?php
        //scan "uploads" folder and display them accordingly
       $folder = "uploads";
       $results = scandir('uploads');
       foreach ($results as $result) {
        if ($result === '.' or $result === '..') continue;

        if (is_file($folder . '/' . $result)) {
            echo '
            <div class="col-md-3">
                <div class="thumbnail">
                    <img src="'.$folder . '/' . $result.'" alt="...">
                        <div class="caption">
                        <p><a href="remove.php?name='.$result.'" class="btn btn-danger btn-xs" role="button">Remove</a></p>
                    </div>
                </div>
            </div>';
        }
       }
       ?>

Cheers!

If you want to add a link where other users can download the files that are uploaded, try adding an <a> tag with the link of the file in it:

<?php
  //scan "uploads" folder and display them accordingly
  $folder = "uploads";
  $results = scandir('uploads');
  foreach ($results as $result) {
    if ($result === '.' or $result === '..') continue;

    if (is_file($folder . '/' . $result)) {
      $file = $folder.'/'.$result;
      echo '<a href="{$file}" target="_blank">{$result}</a><br/>';
      //other codes
    }
  }
?>
