问题描述

I made a header design in html file and everything worked nice, but when I put it in .php file they became like idle so I can't click or hover them. 我在html文件中进行了标头设计，并且一切正常，但是当我将其放在.php文件中时，它们变得很空闲，因此无法单击或将它们悬停。 PHP code: PHP代码： 

<?php
session_start();
require_once "stuff.php";
if (isset($_SESSION['encnick'])){
    header("Location: my.php");
    return;
}
//On form submit
if (isset($_POST['register'])){
    if (!isset($_POST['nick'])){
        $_SESSION['error'] = "Nickname is required";
        header("Location: register.php");
        return;
    }
    if (!isset($_POST['password'])){
        $_SESSION['error'] = "Password is required";
        header("Location: register.php");
        return;
    }
    if (!isset($_POST['cpassword'])){
        $_SESSION['error'] = "Password is required";
        header("Location: register.php");
        return;
    }
    if ($_POST['password'] !== $_POST['cpassword']){
        $_SESSION['error'] = "Passwords don't match";
        header("Location: register.php");
        return;
    }
    else{
        $statement = $pdo->prepare("SELECT * FROM users WHERE nick = :nick");
        $statement->execute(array(':nick' => $_POST['nick']));
        $row = $statement->fetch(PDO::FETCH_ASSOC);
        if ($row['nick'] === $_POST['nick']){
            $_SESSION['error'] = "This nickname is already taken";
            header("Location: register.php");
            return;
        }
        $statement = $pdo->prepare("INSERT INTO users (nick, password, company, encodednick, user_group) VALUES (:nick, :password, :company, :encodednick, :user_group)");
        $statement->execute(array(
                ':nick' => htmlentities($_POST['nick']),
            ':password' => password_hash($_POST['password'], PASSWORD_BCRYPT),
            ':company' => htmlentities($_POST['company']),
            ':encodednick' => md5($_POST['nick']),
            ':user_group' => "user"
            ));
        $_SESSION['encnick'] = md5($_POST['nick']);
        $encnick = $_SESSION['encnick'];
        header("Location: my.php?id=$encnick");
        return;
    }

The menu printing function in stuff.php file: stuff.php文件中的菜单打印功能： 

function printheader(){
    echo "<div id='header'>
    <img src='images/logo.png'>
    <div id='hlinks1'>
        <a href='../index.php'>Home</a>
        <a href='../about.html'>About</a>
        <a href='../support.php' id='hsupbtn'>Support</a>
    </div>
    <div id='hlinks2'>
        <a href='../register.php' id='hregbtn'>Register</a>
        <a href='../login.php'>Login</a>
    </div>
</div>
<div style='height: 110px; position: relative;'></div>";
}

So I mean that when I hover or click links nothing happens at all, they are idle like pictures, but if I disconnect main.css file they start working normally. 所以我的意思是，当我悬停或单击链接时，什么都没有发生，它们像图片一样闲置，但是如果我断开main.css文件的连接，它们将开始正常工作。
