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。
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);
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;
}
