Laravel Where子句-作为var传入？

我希望将where子句动态传递到查询：

User::where('published', '=', '1')->get();

当我尝试传入数组时，会出现以下错误：

$where = ['published', '=', '1'];
User::where($where)->get();

如何传入存储在var中的参数？

您不能这样做。如果出于某种原因，您需要类似但有效的工具，请尝试以下方法：

$where = ['published', '1'];
User::where($where[0], $where[1])->get();

但更好的方法是使用：

在

用户

模型中：

public function scopePublished($query)
{
    return $query->where('published', 1);
}

你能试试这个吗

$attributes = [
                    [
                      'column' =>   'published',
                      'condition' =>   '=',
                      'value' =>  '1'
                    ],
                    [
                      'column' =>   'first_name',
                      'condition' =>   '=',
                      'value' =>  'John' 
                    ],
            ];


 $getUser = User::where(function($query) use($attributes){
                   foreach($attributes as $key => $value){
                   $query->where($value['column'],$value['condition'],$value['value']);
                            }
                        })->get();

您可以执行（部分）原始查询，并将SQL语句作为字符串传入。大概是这样的：

$where = "'published' = '1'";
User::whereRaw($where)->get();

$where = "'published' = :published";
$published = 1;
User::whereRaw($where, compact('published'))->get();

或者像这样：

$where = "'published' = '1'";
User::whereRaw($where)->get();

$where = "'published' = :published";
$published = 1;
User::whereRaw($where, compact('published'))->get();

作用域不是一个更好的方法，因为我必须对每个可能传入的where子句进行作用域
