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:
代码语言:javascript复制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:
代码语言:javascript复制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;
}
