A simple PHP module for handling file uploads with ease.

Installation

You can easily install the Upload module using Composer. Run the following command:

composer require lithemod/upload

Usage

Here's a basic example of how to use the Upload module after installation:

1. Handling File Uploads: Create an HTML form for file uploads:

   <form action="upload.php" method="post" enctype="multipart/form-data">
       <input type="file" name="fileToUpload" />
       <input type="submit" value="Upload" />
   </form>

2. Processing the Upload: In your upload.php, use the Upload class to handle the file:

   <?php
   
   require 'vendor/autoload.php'; // Include Composer's autoloader
   
   use Lithe\Base\Upload;
   
   if ($_SERVER['REQUEST_METHOD'] === 'POST') {
       // Create an instance of the Upload class with the uploaded file
       $upload = new Upload($_FILES['fileToUpload']);
   
       // Specify the upload directory and allowed extensions
       $uploadDir = 'uploads';
       $allowedExtensions = ['jpg', 'png', 'gif', 'txt'];
   
       // Move the uploaded file
       $filePath = $upload->move($uploadDir, $allowedExtensions);
   
       if ($filePath) {
           echo "File uploaded successfully: $filePath";
       } else {
           echo "File upload failed.";
       }
   }

Methods

__construct(array $file)

• Initializes the upload instance with the file data.

move(string $uploadDir, ?array $allowedExtensions = null): ?string

• Moves the uploaded file to the specified directory.
• Generates a unique filename to avoid overwriting.
• Optionally validates the file extension against allowed extensions.

isUploaded(): bool

• Checks if a file is successfully uploaded.

getMimeType(): ?string

• Retrieves the MIME type of the uploaded file.

getSize(): ?int

• Retrieves the size of the uploaded file in bytes.

Error Handling

The module throws exceptions for various error scenarios, including:

• Invalid file upload array
• Upload directory does not exist or is not writable
• File extension not allowed

Make sure to wrap the usage of the module in try-catch blocks to handle exceptions appropriately.

try {
    // Upload handling code
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
