PHP

Video Upload

The following sections describe how to handle video uploads on your server using PHP as a server-side language. For information on the upload workflow refer to the video upload documentation.

Frontend

Setting up the index page.

  1. On the head section include the Editor style. 

    2. <!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <link href="https://cdn.jsdelivr.net/npm/froala-editor@latest/css/froala_editor.pkgd.min.css" rel="stylesheet" type="text/css" />
  </head>
  2. On the body section include the Editor JS files and define the area for the editor.

    3. <body>  
  <script type="text/javascript" src="https://cdn.jsdelivr.net/npm/froala-editor@latest/js/froala_editor.pkgd.min.js"></script>
    
  <div class="sample">
    <h2>Video upload example.</h2>
    <form>
      <textarea id="edit" name="content"></textarea>
    </form>
  </div>
  3. Initialize the editor and set the video upload URL

    4.   <script>
    new FroalaEditor('#edit', {
      // Set the video upload URL.
      videoUploadURL: '/UploadFiles',
      videoUploadParams: {
        id: 'my_editor'
      }
    })
  </script>
</body>
</html>

The full code should look like this:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <link href="https://cdn.jsdelivr.net/npm/froala-editor@latest/css/froala_editor.pkgd.min.css" rel="stylesheet" type="text/css" />
  </head>
    
  <body>
    <script type="text/javascript" src="https://cdn.jsdelivr.net/npm/froala-editor@latest/js/froala_editor.pkgd.min.js"></script>
    
    <div class="sample">
      <h2>Video upload example.</h2>
      <form>
        <textarea id="edit" name="content"></textarea>
      </form>
    </div>
    
    <script>
      new FroalaEditor('#edit', {
        videoUploadURL: '/UploadFiles',
        videoUploadParams: {
          id: 'my_editor'
        }
      })
    </script>
  </body>
</html>

Backend

upload_video.php handles the upload part. It has basic file format validations that can be easily extended.

TThe uploads directory must be set to a valid location before making uploads. The path can be any folder that is accessible and writable.

If the uploaded video passes the validation step, the server responds with a JSON object containing a link to the uploaded video.

e.g.: {"link":"http://server_address/uploads/name_of_file"}.

<?php

  try {
    // File Route.
    $fileRoute = "/uploads/";

    $fieldname = "file";

    // Get filename.
    $filename = explode(".", $_FILES[$fieldname]["name"]);

    // Validate uploaded files.
    // Do not use $_FILES["file"]["type"] as it can be easily forged.
    $finfo = finfo_open(FILEINFO_MIME_TYPE);

    // Get temp file name.
    $tmpName = $_FILES[$fieldname]["tmp_name"];

    // Get mime type. You must include fileinfo PHP extension.
    $mimeType = finfo_file($finfo, $tmpName);

    // Get extension.
    $extension = end($filename);

    // Allowed extensions.
    $allowedExts = array(
      "mp4",
      "webm",
      "ogg"
    );

    // Allowed mime types.
    $allowedMimeTypes = array(
      "video/mp4",
      "video/webm",
      "video/ogg"
    );

    // Validate file.
    if (
      !in_array(strtolower($mimeType), $allowedMimeTypes) ||
      !in_array(strtolower($extension), $allowedExts)
    ) {
      throw new \Exception("File does not meet the validation.");
    }

    // Generate new random name.
    $name = sha1(microtime()) . "." . $extension;
    $fullNamePath = dirname(__FILE__) . $fileRoute . $name;

    // Check server protocol and load resources accordingly.
    if (
      isset($_SERVER["HTTPS"]) &&
      $_SERVER["HTTPS"] != "off"
    ) {
      $protocol = "https://";
    } else {
      $protocol = "http://";
    }

    // Save file in the uploads folder.
    move_uploaded_file($tmpName, $fullNamePath);

    // Generate response.
    $response = new \StdClass;
    $response->link = $protocol .
      $_SERVER["HTTP_HOST"] .
      dirname($_SERVER["PHP_SELF"]) .
      $fileRoute . $name;

    // Send response.
    echo stripslashes(json_encode($response));

  } catch (Exception $e) {
    // Send error response.
    echo $e->getMessage();
    http_response_code(404);
  }

?>
