我在 html 文件中设计了一个页眉，一切正常，但是当我将它放入 .php 文件中时，它们变得空闲，所以我无法单击或悬停它们。 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;
}
}
?>

stuff.php文件中的菜单打印函数:
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>";
}
所以我的意思是，当我悬停或单击链接时，什么也没有发生，它们像图片一样空闲，但如果我断开 main.css 文件，它们就会开始正常工作。
最佳答案
您的打印头功能
<div style='height: 110px; position: relative;'></div>
删除以下内容:-
position: relative
