WordPress ，本地锚点而不是 wp_nav_menu 的完整链接

发布于 2025-01-17 18:02:35 字数 732 浏览 0 评论 0原文

我正在尝试将 href 更改为本地锚点。我的想法是使用 preg_replace 来剥离 home_url();

而不是......

<a href="http://example.com/menu-item/">Menu Item</a>

...我想

<a href="#menu-item/">Menu Item</a>

到目前为止创建我的代码：

$menu_one = wp_nav_menu(
array(
    'echo' => 0,
    'container' => false,
    'menu_class' => '',
    'menu_id' => '',
    'theme_location' => 'main-menu'
    )
);

//get home url
$homeurl = home_url();

$menu_one = preg_replace( $homeurl, '#', $menu_one );
echo '<ul id="main-menu">' . $menu_one . '</ul>';

我目前收到错误 preg_replace()：分隔符不能是字母数字或反斜杠；任何帮助将不胜感激（我的 php 知识非常有限，也许还有一种更优雅的方法来做到这一点）

I'm trying to change the href to a local anchor. My idea was to use preg_replace to strip the home_url();

Instead of....

<a href="http://example.com/menu-item/">Menu Item</a>

...I'd like to create

<a href="#menu-item/">Menu Item</a>

My code so far:

$menu_one = wp_nav_menu(
array(
    'echo' => 0,
    'container' => false,
    'menu_class' => '',
    'menu_id' => '',
    'theme_location' => 'main-menu'
    )
);

//get home url
$homeurl = home_url();

$menu_one = preg_replace( $homeurl, '#', $menu_one );
echo '<ul id="main-menu">' . $menu_one . '</ul>';

I currently get the error preg_replace():
Delimiter must not be alphanumeric or backslash; Any help would be appreciated (my php knowledge is quite limited and also maybe there is a more elegant way to do this)

您需要将 $homeurl 包装在 /$homeurl/ 等分隔符中，使其成为有效的正则表达式模式。

此外，转义 URL 中的某些字符也很重要。

// Some characters must be "escaped" e.g the / must become \/.
$homeurl = preg_quote( $homeurl );

// Wrap the string in a delimiter that preg_replace expects:
$homeurl = "/$homeurl/";

// Now try it:
$menu_one = preg_replace( $homeurl, '#', $menu_one );

You need to make your $homeurl into a valid regex pattern by wrapping it in a delimiter like /$homeurl/.

Also, it is vital to escape some of the characters in the URL.

// Some characters must be "escaped" e.g the / must become \/.
$homeurl = preg_quote( $homeurl );

// Wrap the string in a delimiter that preg_replace expects:
$homeurl = "/$homeurl/";

// Now try it:
$menu_one = preg_replace( $homeurl, '#', $menu_one );
