我一直在编辑代码以帮助解决这个问题，因为我仍然会提出同样的问题，但许多问题似乎都在正确的轨道上。我交替使用mysql和mysqli。我查看了我的dbconnect.php文件，发现以下内容，看起来我还需要进行更改，以使其与其他区域中显示的mysqli保持一致。在正确的轨道上，但还没有实现

我刚刚发现dbconnect.php部署的是mysql版本，而不是mysql版本，有什么想法吗

dbconnect.php

<?php

session_start();

if(isset($_SESSION['user'])!="")

{

    header("Location: home.php");

}
$servername = "correctly inserted info";
$username = "correctly inserted info";
$password = "correctly inserted info";
$dbname = "correctly inserted info";

$conn = new mysqli($servername, $username, $password, $dbname);



if(isset($_POST['btn-signup']))

{
$fname = mysql_real_escape_string($_POST['fullname']);

$uname = mysql_real_escape_string($_POST['username']);

$email = mysql_real_escape_string($_POST['email']);

$upass = md5(mysql_real_escape_string($_POST['password']));


 if(mysql_query("INSERT INTO users(fullname,username,email,password)  VALUES('$fname','$uname','$email','$upass')"))


{

    ?>

    <script>alert('successfully registered');</script>

根据最初的回答，我发现我们帮助我走上了正确的道路……以下是其他相关文件，因为总体主题是我正在交换mysql和mysqli。一开始它的一部分似乎起了作用，但现在它完全崩溃了，所以如果有人能帮我把它重新组装起来，我会很感激的。我仍然没有从发布到数据库的响应，这就是为什么我要进行编辑

index.php

<?php

session_start();

if(isset($_SESSION['user'])!="")

{

    header("Location: home.php");

}
$servername = "correctly inserted info";
$username = "correctly inserted info";
$password = "correctly inserted info";
$dbname = "correctly inserted info";

$conn = new mysqli($servername, $username, $password, $dbname);



if(isset($_POST['btn-signup']))

{
$fname = mysql_real_escape_string($_POST['fullname']);

$uname = mysql_real_escape_string($_POST['username']);

$email = mysql_real_escape_string($_POST['email']);

$upass = md5(mysql_real_escape_string($_POST['password']));


 if(mysql_query("INSERT INTO users(fullname,username,email,password)  VALUES('$fname','$uname','$email','$upass')"))

如评论中所述，您混合了

mysql

mysqli

扩展

错误
您与mysql和mysqli之间存在冲突
名称
属性未在此处定义寄存器
在register.php中，您使用类检查isset，如果（isset（$\u POST['btn-signup']）

以及您的表单
名称字段和检索字段错误（表单-占位符=“全名”name=“fname” /在代码中-mysql\u real\u escape\u字符串（$\u POST['fullname']））

改进要检查变量是否为null或空，请使用empty（）关键字改变这个 if(isset($_SESSION['user'])!="") { header("Location: home.php"); } 对此 if(!empty($_SESSION['user'])){ header("Location: home.php"); } 错误修复代码 register.php中的 if(isset($_POST['register'])){ $fname = mysqli_real_escape_string($conn, $_POST['fname']); $uname = mysqli_real_escape_string($conn, $_POST['uname']); $email = mysqli_real_escape_string($conn, $_POST['email']); $upass = md5(mysqli_real_escape_string($conn, $_POST['pass'])); $sql = "INSERT INTO users(fullname,username,email,password) VALUES('$fname','$uname','$email','$upass')"; if(mysqli_query($conn, $sql)) { ?> <script> alert('successfully registered'); </script> <?php } else{ ?> <script> alert('error while registering you...'); </script> <?php } } <button class="btn btn-sm m-r-5" type="submit" name="register">Register</button> 你把mysql和mysqli混在一起了，有两个原因让你失败了，如果（isset（$\u SESSION['user']）！=“”）-另外，这段代码非常熟悉。您从先前发布的问题所在的位置获取了此信息。您的帖子数组失败了，到目前为止给出的所有答案都没有注意到这一点。您的代码中确实存在语法错误。哦和if（isset（$\u POST['btn-signup']）这永远不会发生。请注意到目前为止所有的回答者：你的答案都会失败。仔细检查，你错过了很多东西。如果你收到否决票，他们不会来自我。我发现了其他类似的东西…在dbconnect.php文件中，我也有相同的mysql调整…我有以下几点：仔细检查，并在他们的问题下查看我的评论我调整了，但似乎仍然没有任何更改…单击register时屏幕闪烁，但是数据库中没有显示任何内容…我确信服务器名称、用户名、密码和数据库名称都是正确的。请仔细检查，然后在它们下面查看我的注释question@Fred-我没让你看他们的表格和帖子arrays@Fred-ii-thanx。收到错误了我觉得很好Abdulla；-）仔细检查，然后在他们的问题下查看我的评论
