Using beforeDelete in Model - dusan - 06-08-2020
Hi,
Let's say I have a table called 'projects'. One of the columns contains a filename string. What i'd like to do, is to delete the file after/before deleting the row from the database. I see, that Codeigniter 4's models can now use a callback function. But i don't know how can I access data, particularly the filename field.
Code:
<?php namespace App\Models;
use CodeIgniter\Model;
class ProjectModel extends Model {
protected $table = 'projects';
protected $primaryKey = 'id';
protected $returnType = 'App\Entities\Project';
protected $useSoftDeletes = false;
protected $allowedFields = ['id', 'title', 'desc', 'filename'];
protected $useTimestamps = true;
protected $createdField = 'created_at';
protected $updatedField = 'updated_at';
protected $afterDelete = ['deleteFiles'];
protected function deleteFiles() {
// here i would like to delete the file
}
}Or am I approaching this the wrong way? Should I just get the data in my Controller, delete the file and then delete the row from database? I would do that in CI3 this way, but now i discovered the callbacks in CI4 and I consider this a more elegant way/better practice. Thanks.
