How do you repopulate form data after submission in FuelPHP?

Handling file uploads in FuelPHP involves setting up an HTML form for file uploads, configuring your controller to handle the file submission, and processing the uploaded file. Here’s a step-by-step guide on how to manage file uploads in FuelPHP:

1. Create an HTML Form for File Uploads

Make sure your form includes the enctype="multipart/form-data" attribute to support file uploads and use the multiple attribute if you want to upload multiple files.

Example Form (fuel/app/views/upload_form.php):

Example


<form action="<?= Uri::base() ?>upload/process" method="post" enctype="multipart/form-data">
    <input type="file" name="file_upload" />
    <input type="submit" value="Upload File" />
</form>

Handle File Upload in the Controller

In your controller, you will handle the file upload by checking for file input, validating the file, and saving it to the server.

Example Controller (fuel/app/classes/controller/upload.php):

Example


<?php

class Controller_Upload extends Controller
{
    public function action_process()
    {
        // Check if a file is uploaded
        if (Input::file('file_upload'))
        {
            // Get file information
            $file = Input::file('file_upload');
            
            // Define the upload directory
            $upload_path = APPPATH . 'uploads/';

            // Define the file name and path
            $filename = $file['name'];
            $destination = $upload_path . $filename;

            // Check if the file was uploaded without errors
            if ($file['error'] === UPLOAD_ERR_OK)
            {
                // Save the file
                if (Upload::save($file, $filename, $upload_path))
                {
                    return Response::forge('File uploaded successfully.');
                }
                else
                {
                    return Response::forge('Failed to save the file.', 500);
                }
            }
            else
            {
                return Response::forge('File upload error: ' . $file['error'], 400);
            }
        }
        else
        {
            return Response::forge('No file was uploaded.', 400);
        }
    }
}

Summary

Create a Form: Use enctype="multipart/form-data" for file uploads.
Handle File in Controller: Process the uploaded file and save it using Upload::save().
Set Permissions: Ensure upload directory has correct permissions.
Validate and Secure: Validate the file and handle security concerns.
