PHP代码提交按钮仅刷新页面
我正在使用PHP和SQL server，在进一步解释之前，数据库连接是使用PHP代码提交按钮仅刷新页面,php,html,mysql,Php,Html,Mysql,我正在使用PHP和SQL server，在进一步解释之前，数据库连接是使用require'databaseconnect.PHP'实现的该代码用于注册用户。目前，运行代码只会刷新页面，在花费数小时尝试排除故障后，我仍然找不到错误。任何帮助都将不胜感激。我不知道我是否正确编程，所以这也可能是问题的根源。我的代码如下： <?php session_start(); $message = ""; require 'databaseconnect.php'; if($_POST['reg

POST['register']
是否返回为真？我相信你需要这样设置：
if(isset($_POST['register')){
//do your thing
}
为了防止出现任何警告，首先也应如此，因为第一次加载时将不存在$\u POST['register']
而且，事实上你没有它可能意味着你关闭了错误和警告？
若要尝试此操作，请将ini\u集（“错误报告”，E\u ALL）位于脚本顶部。如果您有任何错误，这应该说明清楚
此外，请确保在您的if语句中重复某些内容！您不知道页面是否只是刷新，因为如果数据库代码中出现错误，它可能永远无法设置$message
希望这有帮助
另外，我注意到您的表单操作被设置为静态页面（保留为空将自动使用当前页面）——当我还是初学者时，有时会犯错误，使用新文件测试某些内容，结果忘记更改操作url。这有时会导致我加载旧的（备份）文件，而不是带有新测试功能的新文件。只是说说而已。我想你能做的就是先显示错误消息（如果有），然后按常规方式尝试调用你的if语句。如果（）{}然后继续往下走…除了未定义的索引之外，你真的有第一个吗，这个谢谢你，这似乎起作用了，我确实看了那个动作部分，这似乎与if语句检查有关，以确保字段已填充。我不可能看到这个答案如何完整地解决这个问题。显然，它遗漏了很多元素。@Fred ii-我告诉他要正确调试他的if语句。这就是问题所在。虽然一个简单的“你的代码应该是这样”是值得赞赏的，但这个社区是关于学习的，而不是让别人为他们工作。最后，他自己解决了这个问题，再次遇到同样问题的机会很小，因为他是通过这种方式从中吸取教训的。
