我使用Laravel雄辩的查询构建器，我有一个查询，我想在多个条件上有一个where子句。它能起作用，但并不优雅。
例子:
$results = User::where('this', '=', 1)
->where('that', '=', 1)
->where('this_too', '=', 1)
->where('that_too', '=', 1)
->where('this_as_well', '=', 1)
->where('that_as_well', '=', 1)
->where('this_one_too', '=', 1)
->where('that_one_too', '=', 1)
->where('this_one_as_well', '=', 1)
->where('that_one_as_well', '=', 1)
->get();
有没有更好的方法，或者我应该坚持这个方法?

代码示例。
首先:
$matchesLcl=[];
数组在这里被填充使用所需的计数/循环条件，增量:
$matchesLcl['pos']= $request->pos;
$matchesLcl['operation']= $operation;
//+......+
$matchesLcl['somethingN']= $valueN;
更进一步，他又用了这样一种简洁的表达:
if (!empty($matchesLcl))
$setLcl= MyModel::select(['a', 'b', 'c', 'd'])
->where($matchesLcl)
->whereBetween('updated_at', array($newStartDate . ' 00:00:00', $newEndDate . ' 23:59:59'));
else
$setLcl= MyModel::select(['a', 'b', 'c', 'd'])
->whereBetween('updated_at', array($newStartDate . ' 00:00:00', $newEndDate . ' 23:59:59'));
其他回答
使用这个
$users = DB::table('users')
->where('votes', '>', 100)
->orWhere('name', 'John')
->get();
whereColumn方法可以传递一个包含多个条件的数组。这些条件将使用and操作符进行连接。
例子:
$users = DB::table('users')
->whereColumn([
['first_name', '=', 'last_name'],
['updated_at', '>', 'created_at']
])->get();
$users = User::whereColumn([
['first_name', '=', 'last_name'],
['updated_at', '>', 'created_at']
])->get();

你可以在几种情况下使用，
$results = User::where([
['column_name1', '=', $value1],
['column_name2', '<', $value2],
['column_name3', '>', $value3]
])->get();
你也可以这样用，
$results = User::orderBy('id','DESC');
$results = $results->where('column1','=', $value1);
$results = $results->where('column2','<', $value2);
$results = $results->where('column3','>', $value3);
$results = $results->get();
使用Array的条件:
$users = User::where([
'column1' => value1,
'column2' => value2,
'column3' => value3
])->get();
将产生如下查询:
SELECT * FROM TABLE WHERE column1 = value1 and column2 = value2 and column3 = value3
使用匿名函数的条件:
$users = User::where('column1', '=', value1)
->where(function($query) use ($variable1,$variable2){
$query->where('column2','=',$variable1)
->orWhere('column3','=',$variable2);
})
->where(function($query2) use ($variable1,$variable2){
$query2->where('column4','=',$variable1)
->where('column5','=',$variable2);
})->get();
将产生如下查询:
SELECT * FROM TABLE WHERE column1 = value1 and (column2 = value2 or column3 = value3) and (column4 = value4 and column5 = value5)
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();
