Step 1) Install webserver
$ sudo apt-get install apache2 -y
Step 2) Make a directory under /var/www/html/
$ sudo mkdir /var/www/html/sharedoc/
$ sudo mkdir /var/www/html/sharedoc/uploads
$ sudo vim /var/www/html/sharedoc/fileUploadScript.php
<?php
$currentDirectory = getcwd();
$uploadDirectory = "/uploads/";
$errors = []; // Store errors here
$fileExtensionsAllowed = ['sql','jpeg','pdf','jpg','png','exe','dmg','tar.gz','gz','zip']; // These will be the only file extensions allowed
$fileName = $_FILES['the_file']['name'];
$fileSize = $_FILES['the_file']['size'];
$fileTmpName = $_FILES['the_file']['tmp_name'];
$fileType = $_FILES['the_file']['type'];
$fileExtension = strtolower(end(explode('.',$fileName)));
$uploadPath = $currentDirectory . $uploadDirectory . basename($fileName);
if (isset($_POST['submit'])) {
if (! in_array($fileExtension,$fileExtensionsAllowed)) {
$errors[] = "This file extension is not allowed. Please upload a JPEG or PNG file";
}
if ($fileSize < 1024) {
$errors[] = "File exceeds maximum size (4MB)";
}
if (empty($errors)) {
$didUpload = move_uploaded_file($fileTmpName, $uploadPath);
if ($didUpload) {
echo "The file " . basename($fileName) . " has been uploaded";
} else {
echo "An error occurred. Please contact the administrator.";
}
} else {
foreach ($errors as $error) {
echo $error . "These are the errors" . "\n";
}
}
}
?>
Step 4) Add below following content in /var/www/html/sharedoc/index.html
$ sudo vim /var/www/html/sharedoc/index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>File Upload</title>
</head>
<body>
<form action="fileUploadScript.php" method="post" enctype="multipart/form-data">
Upload a File:
<input type="file" name="the_file" id="fileToUpload">
<input type="submit" name="submit" value="Start Upload">
</form>
</body>
</html>
Step 5) Type localhost/sharedoc in browser and add any file.
$ ls /var/www/html/sharedoc/uploads/
