Collection Grouped By Model
This package allows easily group laravel collection by any php object (model, array/collection of models, etc), not only by scalars (strings, numbers, booleans).
Installation
Install via composer
composer require melihovv/collection-grouped-by-model
Usage
$posts = Post::all()
$postsGroupedByAuthor = (new CollectionGroupedByModel($posts))
->groupByModel(function (Post $post) {
return $post->author_id;
}, function (Post $post) {
return $post->author;
});
foreach ($postsGroupedByAuthor as $authorPosts) {
$authorPosts->model(); // returns posts' author
$authorPosts->collection(); // returns author's posts
}Nested grouping: first group products by category, then by manufacturer.
$products = Product::all();
$groupedProducts = (new CollectionGroupedByModel($products))
->groupByModel(function (Product $product) {
return $product->category_id;
}, function (Product $product) {
return $product->category;
})
->transform(function (CollectionGroupedByModel $productsGroupedByCategory) {
return $productsGroupedByCategory
->groupByModel(function (Product $product) {
return $product->manufacturer_id;
}, function (Product $product) {
return $product->manufacturer;
});
});
foreach ($groupedProducts as $categoryProducts) {
$categoryProducts->model(); // returns category
foreach ($categoryProducts->collection() as $manufacturerProducts) {
$manufacturerProducts->model(); // returns manufacturer
$manufacturerProducts->collection(); // returns products grouped by category and manufacturer
}
}Group by several models
$posts = Post::all()
$postsGroupedByAuthorAndCategory = (new CollectionGroupedByModel($posts))
->groupByModel(function (Post $post) {
return "$post->author_id,$post->category_id";
}, function (Post $post) {
return [$post->author, $post->category];
});
foreach ($postsGroupedByAuthorAndCategory as $authorPostsInCategory) {
list($author, $category) = $authorPostsWithCategory->model();
// or using php 7.1 array destruction
[$author, $category] = $authorPostsWithCategory->model();
$authorPostsWithCategory->collection(); // returns author's posts in category
