How to use multiple parameters in where clause? - php

Question

I want to make a filter with different parameters. One of parameter is $article_title. But it can be empty . My problem is even if its not empty i get null in return $comments. That is because this part of code:
$q->where('language_id', $default_language_id)->where('title','like',$article_title);
This is my function
public function getResultCommentsWithArticle($comment,$user_firstname,$article_title,$orderBy){
$default_language = Languages::where('default',1)->first();
$default_language_id = $default_language->id;
$comments = ArticleComments::orderBy($orderBy,'desc')
->with(['user', 'article', 'article.translations' => function($q) use($default_language_id,$article_title) {
$q->where('language_id', $default_language_id)->where('title','like',$article_title);
}])->paginate(10);
return $comments;
}
EDIT:
I also tried like this:
$comments = ArticleComments::orderBy($orderBy,'desc')
->with(['user', 'article', 'article.translations' => function($q) use($default_language_id,$article_title) {
$q->where([
['language_id', '=', $default_language_id],
['title', 'like', '%'. $article_title .'%'],
]);
}])->paginate(10);
But i get all comments and not comments with title="something"

Answer 1

$comments = ArticleComments::orderBy($orderBy,'desc')
->with(['user', 'article'])
->whereHas('article.translations', function($q)
use($default_language_id,$article_title) {
$q->where('language_id', $default_language_id)
->where('title','like',$article_title);
})->paginate(10);

Answer 2

Try this:
$comments = ArticleComments::orderBy($orderBy, 'desc')
->with(['user', 'article' => function ($q) use($default_language_id, $article_title) {
$q->with('translations')
->whereHas('translations', function ($q) use($default_language_id, $article_title) {
$q->where('language_id', $default_language_id)->where('title','like',$article_title);
});
}])->paginate();
This will select all comments and it will attach to it articles that match the translation.title and default language id.
In case you want to filter the comments instead of articles you would do this:
$comments = ArticleComments::orderBy($orderBy, 'desc')
->with(['user', 'article.translation'])
->whereHas('article', function ($q) use($default_language_id, $article_title) {
$q->whereHas('translations', function ($q) use($default_language_id, $article_title) {
$q->where('language_id', $default_language_id)->where('title','like',$article_title);
});
})->paginate();
return $comments;
