HomeBackend DevelopmentPHP Tutorial[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!!)


回复讨论(解决方案)

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');

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
