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?
当前回答
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();

其他回答
Model::where('column_1','=','value_1')
->where('column_2 ','=','value_2')
->get();
OR
// If you are looking for equal value then no need to add =
Model::where('column_1','value_1')
->where('column_2','value_2')
->get();
OR
Model::where(['column_1' => 'value_1',
'column_2' => 'value_2'])->get();
多个where子句
$query=DB::table('users')
->whereRaw("users.id BETWEEN 1003 AND 1004")
->whereNotIn('users.id', [1005,1006,1007])
->whereIn('users.id', [1008,1009,1010]);
$query->where(function($query2) use ($value)
{
$query2->where('user_type', 2)
->orWhere('value', $value);
});
if ($user == 'admin'){
$query->where('users.user_name', $user);
}
终于得到了结果
$result = $query->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 = $results->get();
public function search()
{
if (isset($_GET) && !empty($_GET))
{
$prepareQuery = '';
foreach ($_GET as $key => $data)
{
if ($data)
{
$prepareQuery.=$key . ' = "' . $data . '" OR ';
}
}
$query = substr($prepareQuery, 0, -3);
if ($query)
$model = Businesses::whereRaw($query)->get();
else
$model = Businesses::get();
return view('pages.search', compact('model', 'model'));
}
}
你可以在Laravel 5.3中使用eloquent
所有的结果
UserModel::where('id_user', $id_user)
->where('estado', 1)
->get();
部分结果
UserModel::where('id_user', $id_user)
->where('estado', 1)
->pluck('id_rol');
