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
$variable = array('this' => 1,
'that' => 1
'that' => 1,
'this_too' => 1,
'that_too' => 1,
'this_as_well' => 1,
'that_as_well' => 1,
'this_one_too' => 1,
'that_one_too' => 1,
'this_one_as_well' => 1,
'that_one_as_well' => 1);
foreach ($variable as $key => $value) {
User::where($key, '=', $value);
}
其他回答
$variable = array('this' => 1,
'that' => 1
'that' => 1,
'this_too' => 1,
'that_too' => 1,
'this_as_well' => 1,
'that_as_well' => 1,
'this_one_too' => 1,
'that_one_too' => 1,
'this_one_as_well' => 1,
'that_one_as_well' => 1);
foreach ($variable as $key => $value) {
User::where($key, '=', $value);
}
使用这个
$users = DB::table('users')
->where('votes', '>', 100)
->orWhere('name', 'John')
->get();
根据我的建议，如果你正在做筛选或搜索
那么你应该选择:
$results = User::query();
$results->when($request->that, function ($q) use ($request) {
$q->where('that', $request->that);
});
$results->when($request->this, function ($q) use ($request) {
$q->where('this', $request->that);
});
$results->when($request->this_too, function ($q) use ($request) {
$q->where('this_too', $request->that);
});
$results->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();
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'));
