php - PHP提交表单无法正常工作

问题描述

我对这里的 php 文件有一点问题。表单的标题应该是“Inregistrare”，但总是在页面显示“>”之后它不应该。此外，提交表单不显示错误消息，在 Chrome 中它只是像文本文件一样显示代码。可以请你帮我弄清楚？ PHP：

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8>
 <link rel="icon" type="image/gif" href="icon.png">
<title>Înregistrare</title>
<link rel="stylesheet" type="text/css" href="resources.css">
</head>
<body>
<?php
require_once 'config.php';
$user= $email = $pass = $cpass = "";
$usererr = $emailerr = $passerr = $cpasserr = "";
$user=trim($POST["username"]);
$pass=trim($POST["pass1"]);
$cpass=trim($POST["pass2"]);
$email=trim($POST["email"]);
if($_SERVER["REQUEST_METHOD"] == "POST"){
        if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
                    $emailerr = "Intoduceți o adresă de email validă.";
        }
        else if(empty($email)){
            $usererr = "Introduceți un nume de utilizator.";
        }
        if(empty($user)){
            $usererr = "Introduceți un nume de utilizator.";
        }
        else if(!preg_match("/^[a-zA-Z0-9] *$/",$user)){
            $usererr = "Folosiți doar cifre sau litere.";
        }
        else{
            mysqli_stmt_bind_param($stmt, "s", $user);
            if(mysqli_stmt_execute($stmt)){
                mysqli_stmt_store_result($stmt);
                if(mysqli_stmt_num_rows($stmt) == 1){
                    $usererr = "Acest nume de utilizator nu este disponibil.";
                }
            } else{
                echo "Oops! Ceva nu a mers bine. Te rugăm să încerci mai târziu.";
            }
            mysqli_stmt_close($stmt);
        }
        if(empty($pass)){
        $passerr = "Introduceți o parolă.";} 
        elseif(strlen($pass) < 6){
            $passerr = "Parola trebuie să aiba cel puțin 6 caractere.";
        }
        if(empty($cpass)){
            $cpasserr = 'Vă rugăm confirmați parola.';}
        if($pass != $cpass){
            $cpasserr = 'Parolele nu se potrivesc.';
        }

        //if(empty($usererr) && empty($passerr) && empty($cpasserr)){
    }
