Add Snippet To Project
Are you looking to enhance user navigation on your WordPress site? Adding a "back to parent page" link can greatly improve the user experience, allowing visitors to easily navigate back to the previous page they were on. In this article, we’ll explore how you can achieve this functionality using the get_post_ancestors function in WordPress. Whether you’re a seasoned developer or a beginner, this tutorial will provide you with step-by-step instructions on how to implement a back to parent page link using get_post_ancestors. So, let’s dive right in and enhance your website’s navigation capabilities!
function wpturbo_display_parent_page_link() {
$ancestors = get_post_ancestors();
if (!empty($ancestors)) {
$parent_id = end($ancestors);
$parent_title = get_the_title($parent_id);
$parent_link = get_permalink($parent_id);
echo '<a href="' . $parent_link . '">' . $parent_title . '</a>';
}
}
add_action('wp_footer', 'wpturbo_display_parent_page_link');
The code snippet provided allows you to display a link to the parent page of the current page in a WordPress website. This can be useful when you want to provide a convenient way for users to navigate back to the parent page.
Let’s break down how the code works:
First, we define a new function called wpturbo_display_parent_page_link(). This function will be responsible for retrieving the parent page information and displaying the parent page link.
Inside the function, we use the get_post_ancestors() function to retrieve an array of all the parent page IDs for the current page. This function returns an empty array if there are no parent pages.
Next, we check if the array of ancestors is not empty using the !empty() function. This ensures that we only proceed if there is at least one parent page.
To retrieve the ID of the direct parent page, we use the end() function, which returns the last element of the array. This will be the ID of the immediate parent page.
We then use the get_the_title() function, passing in the parent page ID, to retrieve the title of the parent page.
Similarly, we use the get_permalink() function, passing in the parent page ID, to retrieve the permalink of the parent page.
Finally, we use an echo statement to output an HTML link (<a>) with the parent page title as the link text and the parent page permalink as the link URL.
We hook the wpturbo_display_parent_page_link() function to the wp_footer action, which ensures that the parent page link is displayed in the footer of the current page.
By including this code snippet in your WordPress theme’s functions.php file or in a custom plugin, you can automatically display a link to the parent page on every page where it is applicable.
This can provide a more user-friendly and intuitive navigation experience for your website visitors.
