I have images for articles, and when I am updating article I would like to check if the images are the same, if not I would like to delete them but if it is possible I would like to delete the whole collection without another query, something like what I have in the code below $images->delete();. This is my function:
$images = Media::where('article_id', $article->id)->get(); foreach($images as $image) { $article_images[] = $image->original_name; } foreach($files as $file) { $filePathArr = explode('/', $file); $fileName = array_pop($filePathArr); $originalFile = explode('-', $fileName); $originalFileName = array_pop($originalFile); $newFiles[] = $originalFileName; } if ($newFiles != $article_images){ $images->delete(); }

To delete a whole model collection in Laravel you can make use of the "delete()" method on the collection instance itself. Imagine you have a post and you want to delete the one with an id of 1, 2, 3, 4, 5 then you can write your code like below. <? php Post::query() ->whereIn('id', [1, 2, 3, 4, 5]) ->delete();
In the first example, we are going to use the truncate() function, which is used to delete all the records. In the second example, we will delete records on the basis of the id. So we will specify some id and use the delete() function to delete all the records of that particular id.
Laravel Eloquent Deleting You can delete data after writing it to the database. You can either delete a model instance if you have retrieved one, or specify conditions for which records to delete. To delete a model instance, retrieve it and call the delete() method: $user = User::find(1); $user->delete();
You just can't delete from database without making a query.
You will have to make new request like this:
Media::where('article_id', $article->id)->delete(); It's just one simple query, so there shouldn't be any performance penalty.
If we are talking about collection with 100's of items, you can optimize the query like this:
Media::whereIn('id', $images->pluck('id'))->delete(); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
