Laravel中的where高級(jí)使用方法實(shí)例講解

$username = '';// 收貨人姓名
$hospital_id = ''; // 醫(yī)院id
# 判斷是否有姓名搜索
if (!empty($request->username)) {
  $username = $request->username;
}
# 判斷是否有醫(yī)院搜索
if (!empty($request->hospital_id)) {
  $hospital_id = $request->hospital_id;
}
# 執(zhí)行
$data = DB::table('test')
->where(function($query)use($username){
	# 進(jìn)行判斷
  if (!empty($username)) {
    $query->where('username','Like',"%$username%");
  }
})
->where(function($query)use($hospital_id){
	# 進(jìn)行判斷
  if (!empty($hospital_id)) {
    $query->where('hospital_id','=',$hospital_id);
  }
})
->get()
->toArray();
dd($data)
