@rakibtg Your right, for more complex joins that is excellent and a very nice solution.
I think if the developer just needs simple joins, providing an alternative method can make the business code much cleaner and the usage much easier.
$userStore = \SleekDB\SleekDB::store('user', './sleekdb_test_scripts');
$articleStore = \SleekDB\SleekDB::store('article', './sleekdb_test_scripts');
$users = $userStore
->simpleJoin($articleStore, ['_id', '=', 'author'], 'articles')
->fetch();If the developer has to join three stores:
$userStore = \SleekDB\SleekDB::store('user', './sleekdb_test_scripts');
$articleStore = \SleekDB\SleekDB::store('article', './sleekdb_test_scripts');
$commentStore = \SleekDB\SleekDB::store('comments', './sleekdb_test_scripts');
$users = $userStore
->simpleJoin($articleStore, ['_id', '=', 'author'], 'articles')
->simpleJoin($commentStore, ['_id', '=', 'user'], 'comments')
->fetch();If the developer needs for example also the articles related to the comments:
$userStore = \SleekDB\SleekDB::store('user', './sleekdb_test_scripts');
$articleStore = \SleekDB\SleekDB::store('article', './sleekdb_test_scripts');
$commentStore = \SleekDB\SleekDB::store('comments', './sleekdb_test_scripts');
$users = $userStore
->simpleJoin($articleStore, ['_id', '=', 'author'], 'articles')
->simpleJoin([$commentStore, $articleStore], [['_id', '=', 'user'], ['comments.article', '=', '_id']], 'comments')
->fetch();Or:
$userStore = \SleekDB\SleekDB::store('user', './sleekdb_test_scripts');
$articleStore = \SleekDB\SleekDB::store('article', './sleekdb_test_scripts');
$commentStore = \SleekDB\SleekDB::store('comments', './sleekdb_test_scripts');
$users = $userStore
->simpleJoin($articleStore, ['_id', '=', 'author'], 'articles')
->simpleJoin([$commentStore, $articleStore], [['_id', '=', 'user'], ['article', '=', '_id']], 'comments')
->fetch();Where the second condition just consider the comments-result and joins it with the article store.
But I don't know what could be a nice name for the method.

That is an awesome idea!
Wouldn't it be nicer if we could tweak the join method, for a much easier use?
I am thinking about something like this:
public function join($storeToJoin, $condition, $resultPropertyName)With an usage like this:
$articleStore = \SleekDB\SleekDB::store('article', './sleekdb_test_scripts');
$userStore = \SleekDB\SleekDB::store('user', './sleekdb_test_scripts');
$users = $userStore->join($articleStore, ['author', '=', '_id'], 'articles')->fetch();Or add a new method called leftJoin with a more easy use.

@Timu57 Thanks for your input. I have thought about it at first, but then I realised that we could achieve more with closure JOIN function.
For example,
- Nested join
- Nested join pagination
- Sorting ... etc.
Code example:
<?php
$userStore
->join(function ($user) use ($articleStore) {
return $articleStore
->where('author', '=', $user['_id'])
->join(function ($article) use ($userStore) {
return $userStore
->in('_id', '=', $article['likedUsers'])
->orderBy('desc', '_id' )
->limit(10);
}, 'likedBy');
}, 'articles')
->fetch();Let me know your opinion.
