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?

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
$model = Businesses::get();
return view('pages.search', compact('model', 'model'));
}
}
其他回答
DB::table('users')
->where('name', '=', 'John')
->orWhere(function ($query) {
$query->where('votes', '>', 100)
->where('title', '<>', 'Admin');
})
->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'));
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 $query->get();
public function search()
{
if (isset($_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'));
}
}
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();
