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?

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

如果你的条件是这样的(匹配一个值)，一个简单的更优雅的方式是:
$results = User::where([
'this' => value,
'that' => value,
'this_too' => value,
...
])
->get();
但如果你需要OR子句，那么确保你对每个OR where()子句重复必须满足条件。
$player = Player::where([
'name' => $name,
'team_id' => $team_id
])
->orWhere([
['nickname', $nickname],
['team_id', $team_id]
])
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();
$variable = array('this' => 1,
'that' => 1
'that' => 1,
'this_too' => 1,
'that_too' => 1,
'this_as_well' => 1,
'that_as_well' => 1,
'this_one_too' => 1,
'that_one_too' => 1,
'this_one_as_well' => 1,
'that_one_as_well' => 1);
foreach ($variable as $key => $value) {
User::where($key, '=', $value);
}
DB::table('users')
->where('name', '=', 'John')
->orWhere(function ($query) {
$query->where('votes', '>', 100)
->where('title', '<>', 'Admin');
})
->get();
在Laravel 5.3中(在7.x中仍然如此)，你可以使用更细粒度的数组:
$query->where([
['column_1', '=', 'value_1'],
['column_2', '<>', 'value_2'],
[COLUMN, OPERATOR, VALUE],
...
])
就我个人而言，我还没有发现这个用例超过多个where调用，但事实是你可以使用它。
自2014年6月起，您可以将数组传递到where
只要你想要所有的where use和operator，你可以这样分组:
$matchThese = ['field' => 'value', 'another_field' => 'another_value', ...];
// if you need another group of wheres as an alternative:
$orThose = ['yet_another_field' => 'yet_another_value', ...];
然后:
$results = User::where($matchThese)->get();
// with another group
$results = User::where($matchThese)
->orWhere($orThose)
->get();
以上将导致这样的查询:
SELECT * FROM users
WHERE (field = value AND another_field = another_value AND ...)
OR (yet_another_field = yet_another_value AND ...)
