php - 如何让插入查询与两个 if(isset 语句一起使用？

Question

在用户个人资料上，有一个评论框，其他用户可以在其个人资料上发表评论。我现在正在开发一个动态评论区域，该区域具有不断变化的文本框，具体取决于 A. 您正在查看自己的个人资料 B. 查看别人的个人资料 C. 根本没有登录。

我现在正在尝试实现“更新”，当您在自己的页面上时，在评论框中输入内容，然后它会输出到页面上的指定区域。 (将在社区页面上输出它，但还没有)

在此配置文件页面上，我的插入查询可以很好地插入常规注释(第一个插入查询)，现在我尝试使用第二个插入查询添加第二个 if(isset 语句，但执行此操作时遇到问题。

点击提交按钮后，它没有插入，页面加载为空白。顺便说一句，我是 php 的新手。谢谢:

Answer 1

您将 SQL 放入名为 $query2 的变量中，但在 mysql_query() 调用中将其发送到数据库时，您使用名为 $query 的变量。
