PHP注册表问题，数据库没有接收数据

我有一个用于完美工作的登录系统，我正在编辑并且我的电脑失去了力量，某处有一个错误，我无法看到是否寻找。

有人能发现吗？

<?php
If($_POST){
    mysql_connect("localhost","root","password_here");
    mysql_select_db("users");
    if(isset($_POST['register-submit'])){
    $user_name = $_POST['newusername'];
    $password = $_POST['newpassword1'];
    $email = $_POST['newemail'];
    $name = $_POST['newname'];
    }
    $passwordmd5 = md5($password);
    $query = "insert into username (username,password,email,name) values ('$user_name','$passwordmd5','$email','$name')";
    $query = "DELETE FROM username WHERE username = ''";

    mysql_connect("localhost","root","Oliver");
    mysql_select_db("videos");
    $query = "DELETE FROM videos WHERE name = ''";

    if (mysql_query($query)){
        echo 'registration successful';
        exit;
    }

}
?>

我确定它与$query有关，但无法看到错误。 但是，如果我复制查询并替换像insert into username (username,password,email,name) values ('Usernamehere','Passwordhere','Emailhere','Namehere')这样的数据它可以正常工作，那么它可能与表单有关，不确定。

提前致谢

新代码 

<?php
If($_POST){
mysql_connect("localhost","root","Oliver");
mysql_select_db("users");

$query = "insert into username (username,password,email,name) values ('$user_name','$passwordmd5','$email','$name')";
mysql_query($query) or die(mysql_error());

if (mysql_query($query)){
echo '<center><h1 style="color: green">!Registation Suncessfull!</h1></center>';
}

?>

我不知道该代码是否有效，但如果确实如此，那么执行的唯一查询就是最后一个，就在

之前 
if (mysql_query($query))

该查询是：

$query = "DELETE FROM videos WHERE name = ''";

所以，你的代码唯一能做的就是删除名称为空的表'videos'中的所有行，然后显示“注册成功”。没有意义。

如果你想要执行每个$ query，你应该在每个$ query =“”声明之后调用mysql_query（$ query），否则你只是改变变量的值而不对新值做任何事情。

试试这个：

if($_POST){


    if(isset($_POST['register-submit'])){
    $user_name = $_POST['newusername'];
    $password = $_POST['newpassword1'];
    $email = $_POST['newemail'];
    $name = $_POST['newname'];
    $passwordmd5 = md5($password);
    $query = "insert into username (username,password,email,name) values ('$user_name','$passwordmd5','$email','$name')";   
    mysql_connect("localhost","root","Oliver");
    mysql_select_db("users");
        if (mysql_query($query)){
            echo 'registration successful';               
        } else {
            echo "registration error";
        }
    } else {
        echo "no register-submit";
    }
}

问题在于您使用删除语句重写$query并插入了插入。

不要使用mysql_ * old函数更改MYSQLi或PDO的API并使用预处理语句。

$query = "insert into username (username,password,email,name) values ('$user_name','$passwordmd5','$email','$name')";
//reassign
$query = "DELETE FROM username WHERE username = ''";

mysql_connect("localhost","root","Oliver");
mysql_select_db("videos");
//reassign again!
$query = "DELETE FROM videos WHERE name = ''";

if (mysql_query($query)){

解决此问题：

<?php
    if($_POST){
        mysql_connect("localhost","root","Oliver");
        mysql_select_db("users");
        $query = "insert into username (username,password,email,name) values ('$user_name','$passwordmd5','$email','$name')";
        if (mysql_query($query)){
            echo '<center><h1 style="color: green">!Registation Suncessfull!</h1></center>'; 
        }else{
            echo 'Erro: '. mysql_error();
        }
    }
?>

您发布的更新后的问题：

  

解析错误：语法错误，register.php上的文件意外结束   第134行

最后缺少}。即if($_POST){结尾}在哪里？

此外，不要像这样运行两次查询：

$query = "insert into username (username,password,email,name) 
values ('$user_name','$passwordmd5','$email','$name')";
mysql_query($query) or die(mysql_error());
if (mysql_query($query)){
            echo 'registration successful';}

将更改设为：

$res = mysql_query($query) or die(mysql_error());
if ($res){
echo '<center><h1 style="color: green">!Registation Suncessfull!</h1></center>';
}

修正：

<?php
if($_POST){
mysql_connect("localhost","root","Oliver");
mysql_select_db("users");

$query = "insert into username (username,password,email,name) 
VALUES ('$user_name','$passwordmd5','$email','$name')";
$res = mysql_query($query) or die(mysql_error());

if ($res){
echo '<center><h1 style="color: green">!Registation Suncessfull!</h1></center>';
}
}
?>
  

注意：这仍然是非常不良做法，我恳请您停止使用   已弃用的 mysql函数并移至mysqli或PDO   准备好的陈述，知道为什么/如何帮助。
