Laravel 5.2 - 带阵列的过滤器

我正在做一个搜索过滤器,我有3个输入"市政","类别","关键字",我' m尝试将值插入数组IF输入不为空。像这样:

public function search(Request $request)
    {


        $filter = array(["'visible', '=' , 1"],["'expire_date', '>', $current"]);

        if(!empty($termn)){
                $filter[] =["'title', 'LIKE' , '%'.$termn.'%'"];
        }
        if(!empty($request->input('category'))){
                $filter[] = ["'category_id', '=', $input_category"];
        }
        if(!empty($request->input('municipality_id')))  {
                $filter[] = ["'municipality_id', '=', $input_municipality"];
        }

        dd($filter);

        $posts = Post::where($filter)->get();
}

但它不能很好地过滤,dd($ filter)返回如下: enter image description here

也许数组的结构不行,我也试过这样: laravel 5.2 search query 但它不起作用。 没有dd($ filter)我有这个错误:

感谢您的帮助!

您可以将where()实例中的query builder函数链接为:

$query = Post::where('visible', 1)->where('expire_date', '>', $current);

if(!empty($termn)){
        $query->where('title', 'LIKE', '%'.$termn.'%')
}
if(!empty($request->input('category'))){
        $query->where('category_id', $input_category)
}
if(!empty($request->input('municipality_id')))  {
        $query->where('municipality_id', $input_municipality)
}

$posts = $query->get();

您使用的where子句错误。请参阅以下文档:

模型中where子句的选项应作为参数发送到链式方法(NOT数组值)中,如下所示:

public function search(Request $request)
    {
        $current = Carbon::now();
        $current = new Carbon();
        $termn = $request->input('keyword');
        $input_category = $request->input('category');
        $input_municipality = $request->input('municipality_id');


        $posts = Post::where('visible', 1)->where('expire_date', '>', $current);

        if(!empty($termn)){
                $posts->where('title', 'LIKE' , '%'.$termn.'%');
        }
        if(!empty($request->input('category'))){
                $posts->where('category_id', '=', $input_category);
        }
        if(!empty($request->input('municipality_id')))  {
                $posts->where('municipality_id', '=', $input_municipality);
        }

        $post_results = $posts->get();
        dd($posts_results);
}

请注意,您可以将查询作为数组表(而非模型)的数组发送,如下所示:

$users = DB::table('posts')->where([
    ['visible', '=', '1'],
    ['expire_date', '>', $current],
    // ...
])->get();
