PHP怎么处理多个页面表单传送过来数据问题 请教！！！
四个文件分别为registry1 registry2 registry3 registry_do.php在前两个文件（registry1 registry2）的表单中输入的信息都在第三个文件（registry3）调用第四个文件（registry_do.php 执行处理文件）时才真正写入数据库。怎样才能确保在传送过程中把前三个文件的信息送到第四个文件（registry_do.php）？下边的代码需要怎么样修改才能把前三个文件的信息写入数据库？请前辈指点迷津，谢谢！

alert("<?php echo "注册完成";?>");

我提交后只能把第三个文件的信息写入数据库，前两个文件的信息不能写入数据库代码哪里有问题呢？？？
