Backend
upload_video.php file will do the upload part. It has basic file format validations this can be easily extended.
The uploads directory must be set to a valid location before any uploads are made. The path can be any folder that is accessible and write available.
After processing the uploaded video, if it passes the validation, the server will respond 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);
