在我添加 php.ini 之前，我有一个完美显示的会员注册表单。一旦添加了 php 代码，表单就会完全消失。我已经尝试了一切，但我认为在这个阶段需要一双新的眼睛。任何帮助将不胜感激。干杯。

<?php

if ( $_POST['registerbtn'] ) {
    $getuser = $_POST['user'];
    $getemail = $_POST['email'];
    $getpass = $_POST['pass'];
    $getretypepass = $_POST['retypepass'];

    if ($getuser) {
        if ($getemail) {
            if($getpass) {
                if ($getretypepass) {
                    if ($getpass === $getretypepass) {
                        if ( (strlen($getemail) >= 7) && (strstr($getemail, "@")) && (strstr($getemail, "."))) {
                            require("./connect.php");

                            $query = mysql_query("SELECT * FROM users WHERE username='$getuser'");
                            $numrows = mysql_num_rows($query);
                            if ($numrows == 0){
                                    $query = mysql_query("SELECT * FROM users WHERE email='$getemail'");
                                    $numrows = mysql_num_rows($query);
                                    if ($numrows == 0){

                                        $password = md5($password);
                                        $date = date("F d, Y");
                                        $code = md5(rand());

                                        $query = mysql_query("SELECT * FROM users WHERE username='$getusername'");

您的 echo 语句位于 if ( $_POST['registerbtn'] ) {} 块内，这意味着如果未提交表单，则不会显示该表单。

您在 PHP 代码中有错误，这些错误会阻止任何东西运行。

我建议通过 PHPLint 之类的东西运行您的代码以查看错误。

此外，您可能需要考虑以更易于阅读和维护的方式构建代码。

例如，您可以避免所有那些嵌套的 if 语句并将其编写为：

if (!$getuser) {
   $errormsg = "You must enter username to register.";
}
else if (!$getemail) {
   $errormsg = "You must enter email to register.";
}

我认为你需要使用 else

<?php

if (isset($_POST['registerbtn'])) {
    $getuser = $_POST['user'];
    $getemail = $_POST['email'];
    $getpass = $_POST['pass'];
    $getretypepass = $_POST['retypepass'];

    if ($getuser) {
        if ($getemail) {
            if($getpass) {
                if ($getretypepass) {
                    if ($getpass === $getretypepass) {
                        if ( (strlen($getemail) >= 7) && (strstr($getemail, "@")) && (strstr($getemail, "."))) {
                            require("./connect.php");

                            $query = mysql_query("SELECT * FROM users WHERE username='$getuser'");
                            $numrows = mysql_num_rows($query);
                            if ($numrows == 0){
                                    $query = mysql_query("SELECT * FROM users WHERE email='$getemail'");
                                    $numrows = mysql_num_rows($query);
                                    if ($numrows == 0){

                                        $password = md5($password);
                                        $date = date("F d, Y");
                                        $code = md5(rand());

                                        mysql_query("INSERT INTO users VALUES (
                                            '', '$getuser', '$getpassword', '$getemail', '0', '$getcode', '$getdate'
                                        )");



                                        $query = mysql_query("SELECT * FROM users WHERE username='$getusername'");
                                        $numrows = mysql_num_rows($query);
                                        if ($numrows == 1) {

                                            $message .= "You must activate your account t login.";

                                        }
                                        else
                                            $errormsg = "An error has occured. Your account was not created.\n";


                            }
                            else
                                $errormsg = "There is already a user with that email";

                            }
                            else

编辑：正如 Armon Toubman 所提到的，只有在相关数据已发布到页面时才会显示该表单。您需要将表单移到 if 语句之外。请参见下面的代码：

<?php

if ( $_POST['registerbtn'] ) {
    $getuser = $_POST['user'];
    $getemail = $_POST['email'];
    $getpass = $_POST['pass'];
    $getretypepass = $_POST['retypepass'];

    if ($getuser) {
        if ($getemail) {
            if($getpass) {
                if ($getretypepass) {
                    if ($getpass === $getretypepass) {
                        if ( (strlen($getemail) >= 7) && (strstr($getemail, "@")) && (strstr($getemail, "."))) {
                            require("./connect.php");

                            $query = mysql_query("SELECT * FROM users WHERE username='$getuser'");
                            $numrows = mysql_num_rows($query);
                            if ($numrows == 0){
                                    $query = mysql_query("SELECT * FROM users WHERE email='$getemail'");
                                    $numrows = mysql_num_rows($query);
                                    if ($numrows == 0){

                                        $password = md5($password);
                                        $date = date("F d, Y");
                                        $code = md5(rand());

                                        mysql_query("INSERT INTO users VALUES (
