Upload video files via PHP and save them in appropriate folder and have a database entry

Tags:

php

I want the user to be able to upload video files to my site and I want them arranged in proper folders plus a database entry so that later I can know the person who uploaded each particular file.

My HTML form is here:

<form method="post" enctype="multipart/form-data">
    <div><?php echo $message; ?></div>
    <?php echo $max_file_size_tag; ?>
    <input type="file" accept="video/*" ID="fileSelect" runat="server" size="20" name="filename" action="/vids/file-upload.php">
    <select name="course">
        <option value="select" selected>Select</option>
        <option value="java">Java</option>
        <option value="python">Python</option>
        <option value="vb">Visual Basic</option>
        <option value="c">C/C++</option>
        <option value="ruby">Ruby</option>
    </select>
    <input type="submit" value="Upload" name="submit">
</form>

And my PHP is here:

<?php

$folder  = isset($_POST["course"]);
$message = "1";

define('DESTINATION_FOLDER','/$folder);

define('MAX_FILE_SIZE', 0);

// Upload success URL. User will be redirected to this page after upload.
define('SUCCESS_URL','learn.learnbrix.com');

// Allowed file extensions. Will only allow these extensions if not empty.
// Example: $exts = array('avi','mov','doc');
$exts = array();

// rename file after upload? false - leave original, true - rename to some unique filename
define('RENAME_FILE', true);

$message = "renamed";
// put a string to append to the uploaded file name (after extension);
// this will reduce the risk of being hacked by uploading potentially unsafe files;
// sample strings: aaa, my, etc.
define('APPEND_STRING', '~');

$message = "string append";
// Need uploads log? Logs would be saved in the MySql database.
define('DO_LOG', false);

// MySql data (in case you want to save uploads log)
define('DB_HOST','  '); // host, usually localhost
define('DB_DATABASE','  '); // database name
define('DB_USERNAME','  '); // username
define('DB_PASSWORD','  '); // password

/* NOTE: when using log, you have to create MySQL table first for this script.
Copy-paste following into your MySQL admin tool (like PhpMyAdmin) to create a table
If you are on cPanel, then prefix _uploads_log on line 205 with your username, so it would be like myusername_uploads_log

CREATE TABLE _uploads_log (
  log_id int(11) unsigned NOT NULL auto_increment,
  log_filename varchar(128) default '',
  log_size int(10) default 0,
  log_ip varchar(24) default '',
  log_date timestamp,
  PRIMARY KEY  (log_id),
  KEY (log_filename)
);

I have no knowledge of PHP, so I don't know what's going wrong. I'd also like to add the capability to accept names and their email addresses.

"Could you suggest a simpler code main thing is uploading the file Data base entry is secondary"

^--- As per OP's request. ---^

Image and video uploading code (tested with PHP Version 5.4.17)

HTML form

<!DOCTYPE html>

<head>
<title></title>
</head>

<body>

<form action="upload_file.php" method="post" enctype="multipart/form-data">
<label for="file"><span>Filename:</span></label>
<input type="file" name="file" id="file" /> 
<br />
<input type="submit" name="submit" value="Submit" />
</form>

</body>
</html>

PHP handler (upload_file.php)

Change upload folder to preferred name. Presently saves to upload/

<?php

$allowedExts = array("jpg", "jpeg", "gif", "png", "mp3", "mp4", "wma");
$extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);

if ((($_FILES["file"]["type"] == "video/mp4")
|| ($_FILES["file"]["type"] == "audio/mp3")
|| ($_FILES["file"]["type"] == "audio/wma")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg"))

&& ($_FILES["file"]["size"] < 20000)
&& in_array($extension, $allowedExts))

  {
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

    if (file_exists("upload/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
      }
    }
  }
else
  {
  echo "Invalid file";
  }
?>
