一、需求:
在数据搜索时最常见的就是调用同一个方法查询,而查询的字段却可能是其中一个或其中的几个字段一起组合查询,例如:对列表的搜索,基本上都是几个字段随意组合搜索。那么在model里就需要判断有那个字段组合,怎么组合。
网上找了很久,Laravel群里也问了几个,都说没有写过,于是自己写个吧。话不多说,见代码:
- function findByParam($param = array())
- {
- $select = new Customer();
- if (isset($param['name']) && '' != $param['name'])
- {
- $select = $select->where('customer.name', '=', $param['name']);
- }
- if (isset($param['phone']) && '' != $param['phone'])
- {
- $select = $select->where('customer.phone', '=', $param['phone']);
- }
- if (isset($param['email']) && '' != $param['email'])
- {
- $select = $select->where('customer.email', '=', $param['email']);
- }
- if (isset($param['tel']) && '' != $param['tel'])
- {
- $select = $select->where('customer.tel', '=', $param['tel']);
- }
- if (isset($param['qq']) && '' != $param['qq'])
- {
- $select = $select->where('customer.qq', '=', $param['qq']);
- }
- if (isset($param['IDCard']) && '' != $param['IDCard'])
- {
- $select = $select->where('customer.IDCard', '=', $param['IDCard']);
- }
-
- $customers = $select->leftJoin("member", function ($join)
- {
- $join->on("customer.memberID", "=", "member.id");
- })
- ->get(array(
- 'customer.id',
- 'customer.name',
- 'customer.sex',
- 'customer.tel',
- 'customer.phone',
- 'customer.address',
- 'customer.email',
- 'customer.qq',
- 'customer.headPic',
- 'customer.birthday',
- 'customer.IDCard',
- 'customer.enable',
- 'customer.memberID',
- 'customer.IDCard',
- 'customer.info',
- 'member.name as mname',
- 'member.discount'
- ));
- return json_encode($customers);
调用的时候,controller里只需要接收这些字段,无论它是否有值,直接加入到$param数组中查询就OK,例如:
- function anyFindbyparam()
- {
- $name = Input::get('name');
- $tel = Input::get('tel');
- $phone = Input::get('phone');
- $email = Input::get('email');
- $qq = Input::get('qq');
- $IDCard = Input::get('IDCard');
- $customer = new Customer();
- $customers = $customer->findByParam(array(
- 'name' => $name,
- 'tel' => $tel,
- 'phone' => $phone,
- 'email' => $email,
- 'qq' => $qq,
- 'IDCard' => $IDCard
- ));
- return $customers;
- }
