[ThinkPHP]关联查询问题
使用ThinkPHP框架开发.
User模型里关联了personalapply表:
'personalapply' =>array(
'mapping_type'=>self::HAS_MANY,
'foreign_key'=>'uid',
'mapping_name'=>'personalapply',
),
控制器里:根据前端接收的字段查询筛选(字段为personalapply表里字段)
//获取个人中心的申请信息
$limit_year = $_GET['limit_year'];
$loanuse = $_GET['loanuse'];
//申请表关联查询条件
$user=D('user');
$applymap['limit_year'] = $limit_year;
$applymap['loanuse'] = $loanuse;
$userapply=$user->relation('personalapply')->where($applymap)->select();//只能查询user表字段,不能查询personalapply表字段,
问题:想要user表跟personalapply表关联后怎么根据变量查询 personalapply里数据,得出关联后的查询数据。模型里condition只能写死!不能传变量。(我新手也看手册了,手册里没有,估计是我知道的函数不全,ThinkPHP不行我就使用PHP SQL查询了,求大神指出ThinkPHP实现的方法,THX!!)

建议你使用视图模型来查询:写一个自定义Model(如果是TP3.2版本,别忘了引入命名空间)
class UserPersonalapplyViewModel extends ViewModel{ public $viewFields = array( 'User'=>array( 'User表需要取的字段1', '字段2', '字段3' ), 'personalapply'=>array( 'personalapply表需要取得字段1', '字段2', '字段3', '_on'=>'User.主键=personalapply.uid', '_type'=>'LEFT' ), );}
然后在控制器里实例化这个模型来取数据即可。
$UserPersonal = D('UserPersonalapplyViewModel');

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
