        $password_conf = $db->real_escape_string($_POST['password_conf']);
        $nick = $db->real_escape_string($_POST['nick']);

        //create_new_user($username, $password, $password_conf, $nick);
        //$db->query
        //('
            //INSERT INTO  `idoctor_db`.`users` (`ID` ,`Login` ,`Password` ,`Name` ,`Level`)

Answer 1

如果运行此查询时没有错误，您将看到一个空白页。

所有工作都在后台进行，查看你的mysql表以确认插件是否有效。

如果您想检查查询的结果......只需执行以下操作

$outcome = $db->query
('

    INSERT INTO  `idoctor_db`.`users` (
    `ID` ,
    `Login` ,
    `Password` ,
    `Name` ,
    `Level`
    )
    VALUES 
    (' 4 ', ' kev4 ', ' root ', ' kevkev4 ', ' 3 ');
');

if($outcome) {
    echo 'success';
} else {
    echo 'failed';
}

Answer 2

编辑完成后......我在您的代码中看到了另一个问题：

<form action="<?php create(); ?>" method="POST">
         <!--     ^ This is not how you submit form data to php... 
             action is supposed to be a URL.. however if left blank 
             it will take you to the same page

请改为尝试：

<?php
    if(isset($_POST["submit"]))
    {       
        $db = new mysqli('localhost', 'root', 'root', 'idoctor_db');

        $username = $db->real_escape_string($_POST['username']);
        $password = $db->real_escape_string($_POST['password']);
        $password_conf = $db->real_escape_string($_POST['password_conf']);
        $nick = $db->real_escape_string($_POST['nick']);

        //create_new_user($username, $password, $password_conf, $nick);
        //$db->query
        //('
        //INSERT INTO  `idoctor_db`.`users` (`ID` ,`Login` ,`Password` ,`Name` ,`Level`)
        //VALUES ('5 ' , 'kev5', 'roo5', 'kevkev5', ' 3 ' );
        //');
    }

?>
