Question

我有一个if语句的问题，我正在尝试使用php include激活我正在使用的页面，这是我的包含代码;

<?php
echo '
<div class="container">
<nav class="navbar navbar-inverse">
    <div class="container-fluid">
        <div class="navbar-header">
                <a class="navbar-brand" href="/womsy/home.php">Womsy</a>
        </div>
            <ul class="nav navbar-nav">
                <li <?php if ($page = "home") {class=active;} else {echo "Failed to load active class."} ?><a href="?page=home">Home</a></li>
                <li><a href="?page=blog">Blog</a></li>
                <li><a href="?page=projects">Projects</a></li>
                <li><a href="?page=contact">Contact</a></li>
                <li><a href="?page=about">About</a></li>
            </ul>
    </div>
</nav>';
?>

这就是我的方式：

<?php
include ('php/includes/menu.php');
?>

所以我试图激活“主页”页面，有人可以帮我这个吗？

试试这个：

<?php
$page = "";
if(isset($_GET["page"]) && $_GET["page"] != "") {
$page = $_GET["page"];
}
?>

<div class="container">
<nav class="navbar navbar-inverse">
    <div class="container-fluid">
        <div class="navbar-header">
                <a class="navbar-brand" href="/womsy/home.php">Womsy</a>
        </div>
            <ul class="nav navbar-nav">
                <li <?php if ($page == "home") { echo "class='active'";} ?>><a href="?page=home">Home</a></li>
                <li <?php if ($page == "blog") { echo "class='active'";} ?>><a href="?page=blog">Blog</a></li>
                <li <?php if ($page == "projects") { echo "class='active'";} ?>><a href="?page=projects">Projects</a></li>
                <li <?php if ($page == "contact") { echo "class='active'";} ?>><a href="?page=contact">Contact</a></li>
                <li <?php if ($page == "about") { echo "class='active'";} ?>><a href="?page=about">About</a></li>
            </ul>
    </div>
</nav>

Answer 2

您需要修复if块

if ($page = "home")

到

if ($page == "home")

Answer 3

我认为你有错误

<?php if ($page = "home") {class=active;} else {echo "Failed to load active class."} ?>

应该是

<?php if ($page == "home") {class=active;} else {echo "Failed to load active class."} ?>

导航栏当前类更改php包括
