Php 如何使用if语句在某些页面上显示页脚内容

我是php新手，我只想在2页上显示特定的页脚内容

我知道我会使用if语句，但我不知道在php中是否有办法知道显示的是什么页面

下面是footer.php

<?php
/**
 * The template for displaying the footer.
 *
 * Contains the closing of the id=main div and all content after
 *
 * @package WordPress
 * @subpackage Twenty_Eleven
 * @since Twenty Eleven 1.0
 */
?>

    </div><!-- #main -->

    <footer id="colophon" role="contentinfo">

            <?php
                /* A sidebar in the footer? Yep. You can can customize
                 * your footer with three columns of widgets.
                 */
                get_sidebar( 'footer' );
            ?>

            <div class="boli-better">

Touch screens have simplified technology, but there has yet to be a way to capture the precision of a calligrapher or the stroke of an artist. Not only should it meet your needs, but a stylus should have style.

为什么博利更好？
完全加权
触摸屏简化了技术，但至今还没有一种方法可以捕捉书法家的精准度或艺术家的笔触。它不仅应该满足你的需要，而且笔应该有风格。
笔式精度
你的手写笔应该和你的想法一样锋利。薄而清晰的光盘为您提供数字笔所需的准确度。
圆珠笔
以您最舒适的角度握住手写笔。Jot给你自由写作或素描，就像你习惯的那样。
重金属
一旦你掌握了这一点，质量就不会有错。耐用的铝和钢赋予Jot优越的导电性和工艺，可与任何豪华笔媲美。

好的，这就是我想出来的，但是当我将这段代码添加到footer.php时，整个页脚不会出现在网站上

我肯定我犯了一个基本的错误，所以提前谢谢你的帮助

$page = 'shop';
if (is_page($page)) { ?>

看看PHP的。您可能正在查找

$\u服务器['REQUEST\u URI']

if ($_SERVER['REQUEST_URI'] == "/index.php") {
   echo "My stuff to show on /index.php";
}

---

您可以在希望检查的页面上设置一个特殊变量（并在页脚的if语句中使用），或者使用@Christofer Eliasson的答案，该答案使用服务器的请求URI变量检查WP代码。我想说的是，_page（）就是你想要的：

你想要的是：

<?php
     if (is_page(array('page1','page2'))) {
       <!-- Fotter content displayed here --> 
     }
?>

请发布与问题相关的代码。理想情况下，除了问题正文中的代码之外，请添加问题的示例。它将帮助我们帮助您。如果您可以查看，我使用is_page（）将失败的代码添加到问题中。我不认为它是这样工作的，您不需要设置变量。WP会帮你解决的。请阅读：我认为它与文件名不匹配，而是与slug名称匹配。来自Codex：“当显示带有“关于我”的帖子名（slug）的页面时，是页面（'about me'）。@nearyprgrm不幸的是，我没有WP的经验，但根据文档，我最好的猜测是：

WP_reset_query（）；如果（是页面（“商店”）{//做你的事}

。您是否尝试过我的示例，但没有使用WP特定的函数？@nearyorprgrm Sweet！很乐意帮忙。
