POST的数据为空
下面是我想实现的：
用户点击编辑之后利用ajax调用一个新的界面，然后编辑完之后单击提交POST到后台操作

但是发现post之后都是空数据，是什么原因呢？该怎么解决呢？
下面是我的编辑页代码

<?php <br />session_start();<br>include("../conn/conn.php");<br>include("../inc/func.php");<br>$pw_id=$_GET['pw_id'];<br>$sql="SELECT `pw_id`,`k1`,`k2`,`k3`,year,`student_num`,`week_time`,`has_exam`,paee_work_theory.`remark`,`co_tid`,`verify`,`weeks`,paee_course.name FROM `paee_work_theory`,paee_course WHERE paee_course.pc_id=paee_work_theory.pc_id and pw_id='$pw_id' order by paee_work_theory.pw_id desc";<br>$record=mysql_query($sql,$conn);<br>$row=mysql_fetch_array($record);	<br>header('Content-type:text/html;charset=GBK');<br>?><br>

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
