使用Eloquent很容易创建多个where检查:

首先:(使用简单的where)

$users = User::where('name', $request['name'])
    ->where('surname', $request['surname'])
    ->where('address', $request['address'])
    ...
    ->get();

第二个:(在数组中分组where)

$users = User::where([
    ['name', $request['name']],
    ['surname', $request['surname']],
    ['address', $request['address']],
    ...
])->get();

你也可以在里面使用条件(=，<>，等等)，就像这样:

$users = User::where('name', '=', $request['name'])
    ->where('surname', '=', $request['surname'])
    ->where('address', '<>', $request['address'])
    ...
    ->get();

$projects = DB::table('projects')->where([['title','like','%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])
->orwhere([['owner', 'like', '%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])->get();

$variable = array('this' => 1,
                    'that' => 1
                    'that' => 1,
                    'this_too' => 1,
                    'that_too' => 1,
                    'this_as_well' => 1,
                    'that_as_well' => 1,
                    'this_one_too' => 1,
                    'that_one_too' => 1,
                    'this_one_as_well' => 1,
                    'that_one_as_well' => 1);

foreach ($variable as $key => $value) {
    User::where($key, '=', $value);
}

多个地方

您还可以将一个条件数组传递给where函数。数组的每个元素都应该是一个数组，包含通常传递给where方法的三个参数:

Model::where([
    ['status', '=', '1'],
    ['subscribed', '<>', '1'],
])->get();

多个或Where子句

如果你需要在圆括号内对"or"条件进行分组，你可以将闭包作为第一个参数传递给orWhere方法:

Model::where('votes', '>', 100)
        ->orWhere(function ($query) {
            $query->where('name', 'abcd')
                ->orWhere(function ($query) {
                    $query->where('name', 'cdef')
                        ->where('votes', '>', 50);
                });
        })
        ->get();

上面的例子将产生以下SQL语句:

select * from `users` where `votes` > 100 or (`name` = "abcd" or (`name` = "cdef" and `votes` > 50));

多指针where with whereNot和orWhereNot方法

whereNot和orWhereNot方法可用于对给定的查询约束组求反。例如，以下查询排除清仓或价格小于10的产品:

$products = Product::where([
        ['status', '=', '1'],
        ['is_feature', '1']
    ])
        ->whereNot(function ($query) {
            $query->where('clearance', true)
                ->orWhere('price', '<', 10);
        })
        ->get();

一定要对子查询应用任何其他过滤器，否则or可能会收集所有记录。

$query = Activity::whereNotNull('id');
$count = 0;
foreach ($this->Reporter()->get() as $service) {
        $condition = ($count == 0) ? "where" : "orWhere";
        $query->$condition(function ($query) use ($service) {
            $query->where('branch_id', '=', $service->branch_id)
                  ->where('activity_type_id', '=', $service->activity_type_id)
                  ->whereBetween('activity_date_time', [$this->start_date, $this->end_date]);
        });
    $count++;
}
return $query->get();

您可以在where子句中使用数组，如下所示。

$result=DB::table('users')->where(array(
'column1' => value1,
'column2' => value2,
'column3' => value3))
->get();
