Trying to get property of non-object in aside - php

Question

I´m trying to do a simple blog with Laravel 5.3. Index page include aside with categories and tags, and we can filter different post with categories or tags names.
In routes I have this.
Route::get('categories/{name}',[
'as'=>'front.search.category',
'uses'=>'FrontController#searchCategory'
]);
Route::get('tags/{name}',[
'as'=>'front.search.tag',
'uses'=>'FrontController#searchTag'
]);
In Article
public function scopeSearchCategory($query,$name){
$query->where('name','=',$name);
}
In Tag
public function scopeSearchTag($query,$name){
$query->where('name','=',$name);
}
In FrontController.
public function searchCategory($name){
$tags=Tag::all();
$sliders=Slider::all();
$categories = Category::SearchCategory($name)->first();
$articles = $categories->articles()->paginate(5);
$articles->each(function($articles){
$articles->category;
$articles->images;
});
return view('front.index')->with('articles', $articles)->with('sliders', $sliders)->with('categories', $categories)->with('tags',$tags);
}
public function searchTag($name){
$categories=Category::all();
$sliders=Slider::all();
$tags = Tag::SearchTag($name)->first();
$articles = $tags->articles()->paginate(5);
$articles->each(function($articles){
$articles->category;
$articles->images;
});
return view('front.index')->with('articles', $articles)->with('sliders', $sliders)->with('categories', $categories)->with('tags',$tags);
}
In aside
<aside class="panel panel-primary">
<div class="panel-heading">
<h2 class="panel-title">{{trans('app.title_categories')}}</h2>
</div>
<div class="panel-body">
<ul class="list-group">
#foreach($categories as $category)
<a href="{{route('front.search.category',$category->name)}}">
<li class="list-group-item">
<span class="badge">{{$category->articles->count()}}</span>
{{$category->name}}
</li>
</a>
#endforeach
</ul>
</div>
</aside>
<aside class="panel panel-success">
<div class="panel-heading">
<h2 class="panel-title">Tags</h2>
</div>
<div class="panel-body">
<ul class="list-group">
#foreach($tags as $tag)
<a href="{{route('front.search.tag',$tag->name)}}">
<li class="list-group-item">
<span class="badge">{{$tag->articles->count()}}</span>
{{$tag->name}}
</li>
</a>
#endforeach
</ul>
</div>
</aside>
When a click on aside href to filter tags or categories return 'Trying to get property of non-object'. If I remove scopeSearchs and put in FrontController functions $Tag:all() or Category:all() href works, but filter fail, return all post. ¿Any idea why return this error? ¿Can´t do foreach if return one object?

Answer 1

You should use
$tags = Tag::searchTag($name)->first();
When you are using scope function it should always be camelCase
so searchTag() should be start with small s not capital s
You should remove foreach
use this
<a href="{{route('front.search.tag',$tags->name)}}">
<li class="list-group-item">
<span class="badge">{{$tags->articles->count()}}</span>
{{$tags->name}}
</li>
</a>
