I am working on a Laravel Livewire application and need to refactor the file upload functionality to use an event and listener approach for better scalability and separation of concerns. I’m encountering issues where the processed_participants
array is empty after implementing the new structure. Below are the details of my implementation and the issues I’m facing.
Current Implementation
Here’s the original file_uploaded
function in the CreateNewBatchForm
Livewire component:
CreateNewBatchForm Livewire Component
public function file_uploaded(FileUpload $file_upload, $file_upload_type) {
$this->file_uploaded_successfully = true;
$this->file_upload = $file_upload;
$this->file_upload_type = $file_upload_type;
// Reset our array of processed participants
$this->processed_participants = ['accepted' => [], 'rejected' => []];
if ($file_upload_type == "xlsx" || $file_upload_type == "xls") {
$import = new AppImportsParticipantsImport();
Excel::import($import, $file_upload->file_location);
$participants = $import->get_participants();
} else {
$csv_data = Storage::get($file_upload->file_location);
$lines = explode(PHP_EOL, $csv_data);
$participants = [];
foreach ($lines as $line) {
$participants[] = str_getcsv($line);
}
}
// Process participants here...
}
Refactoring Steps
-
Created an Event:
FileUploaded
with parametersFileUpload
model instance and file type. -
Implemented a Listener:
ProcessUploadedFile
to process the file. -
Dispatched the Event: From the Livewire component replacing direct processing logic.
Issues Encountered
After refactoring, the processed_participants
array remains empty despite files being uploaded successfully. There are no error messages logged, making it difficult to diagnose the issue.
Specific Questions
-
How can I ensure the event-driven architecture processes the file uploads correctly?
-
What could be causing the
processed_participants
array to return empty and how can I debug this issue effectively?
Environment
-
Laravel Version: 8.x
-
Livewire Version: 2.x
-
PHP Version: 7.4
What are the best practices for refactoring the file_uploaded method to use events and listeners in Laravel?
