Using WordPress get_permalink() for Easy URL Generation

Broken links frustrate users and harm search visibility. In WordPress, ensuring accurate URL generation is paramount. The WordPress get_permalink() function directly addresses this, dynamically retrieving the correct URL for pages and posts, along with custom post types.

This prevents manual URL updates, which are prone to errors and time-consuming. For developers, understanding this function is crucial for building robust and maintainable WordPress sites.

In this blog, I’ll explain how the WordPress development experts use get_permalink() among other key functions and get the best of these for the website.

What is get_permalink()?

The get_permalink() function in WordPress is used to retrieve the permalink (or permanent URL) of a specific post, page, or custom post type. A permalink is the full URL that points to a specific piece of content on your website.

For example, if you have a blog post titled “How to Use WordPress,” the permalink might look something like this: https://yourwebsite.com/how-to-use-wordpress/

The WordPress get_permalink() function allows you to programmatically retrieve this URL, which can be useful in various scenarios, such as creating custom navigation, generating links dynamically, or simply displaying the URL of a post.

Syntax

The basic syntax of the get_permalink() function is as follows:

get_permalink( int|WP_Post $post, bool $leavename = false ): string|false

$post (int|WP_Post)

This parameter can be either a post ID (integer) or a WP_Post object. If you pass a post ID, the function will retrieve the permalink for that specific post. If you pass a WP_Post object, it will use that object to retrieve the permalink.

$leavename (bool)

This is an optional parameter that defaults to false. If set to true, the function will return the permalink structure without replacing the placeholder for the post name. This is useful if you want to manipulate the URL structure before finalizing it.

Return Value

The function returns the full permalink structure as a string if successful. If the post does not exist or an error occurs, it returns false.

In short, get_permalink() is a handy WordPress function that fetches the permanent URL of posts, pages, or custom content. It’s perfect for creating dynamic internal links, custom navigation, or simply displaying URLs programmatically.

By mastering this function, you can enhance your site’s flexibility and user experience. Next, we’ll dive into practical examples and tips to help you use WordPress get_permalink() effectively. Let’s get started!

How to Use WordPress get_permalink()?

Whether you’re working within the WordPress Loop, retrieving URLs for specific posts, or handling custom post types, get_permalink() provides a simple yet powerful way to generate permalinks dynamically.

Using get_permalink() is straightforward. Below are some common use cases and examples to help you understand how to implement this function in your WordPress theme or plugin.

Retrieving the Permalink of the Current Post

If you’re inside the loop (e.g., in a single post template), you can retrieve the permalink of the current post using the following code:

$permalink = get_permalink();

echo '<a href="' . esc_url($permalink) . '">Read More</a>';

In this example, get_permalink() is called without any parameters, so it automatically retrieves the permalink of the current post in the loop.

Retrieving the Permalink of the Post by ID

If you want to retrieve the permalink of the post by its ID, you can pass the post ID as a parameter:

$post_id = 123; // Replace with your post ID

$permalink = get_permalink($post_id);

echo '<a href="' . esc_url($permalink) . '">Visit Post</a>';

This code will output a link to the post with the ID of 123.

Retrieving the Permalink of a Page

You can also use WordPress get_permalink() to retrieve the permalink of a page. Pages in WordPress are just another type of post, so the function works the same way:

$page_id = 456; // Replace with your page ID

$permalink = get_permalink($page_id);

echo '<a href="' . esc_url($permalink) . '">Visit Page</a>';

Using get_permalink() with Custom Post Types

WordPress allows you to create custom post types, and get_permalink works seamlessly with them. For example, if you have a custom post type called product, you can retrieve the permalink of a specific product like this:

$product_id = 789; // Replace with your product ID

$permalink = get_permalink($product_id);

echo '<a href="' . esc_url($permalink) . '">View Product</a>';

Using the $leavename Parameter

The $leavename parameter can be useful if you want to manipulate the URL structure before finalizing it. For example, if you want to retrieve the permalink structure without replacing the placeholder for the post name, you can do the following:

$post_id = 123; // Replace with your post ID

$permalink = get_permalink($post_id, true);

echo $permalink; // Outputs something like: https://yourwebsite.com/%postname%/

This can be useful if you want to programmatically modify the URL before using it.

With get_permalink(), generating dynamic URLs for your content is quick and easy. Whether you’re linking posts or customizing permalink structures, this function is a versatile tool for any WordPress project. Next, let’s cover some best practices to ensure you’re using it effectively.

Best Practices For Using WordPress get_permalink

While get_permalink() is a powerful tool, there are a few common mistakes that can trip you up if you’re not careful. In this section, we’ll highlight these pitfalls and provide best practices to ensure you’re using the function efficiently and securely. By keeping these tips in mind, you’ll be able to avoid errors and make your WordPress projects more robust.

While get_permalink() is a powerful function, there are some common pitfalls and best practices to keep in mind:

Always Escape URLs

When outputting URLs in your theme or plugin, always use the esc_url() function to ensure that the URL is properly escaped and safe to use:

$permalink = get_permalink($post_id);

echo '<a href="' . esc_url($permalink) . '">Visit Post</a>';

Check for False Returns

Since get_permalink can return false if the post does not exist or an error occurs, it’s a good practice to check the return value before using it:

$permalink = get_permalink($post_id);

if ($permalink) {

echo '<a href="' . esc_url($permalink) . '">Visit Post</a>';

} else {

echo 'Post not found.';

}

Use get_the_permalink() for Simplicity

If you’re inside the loop and want to retrieve the permalink of the current post, you can use the simpler get_the_permalink() function, which is a wrapper for get_permalink:

$permalink = get_the_permalink();

echo '<a href="' . esc_url($permalink) . '">Read More</a>';

Consider Caching

If you’re retrieving permalinks for multiple posts in a loop, consider caching the results to improve performance. WordPress already caches permalinks internally, but if you’re performing complex operations, caching can still be beneficial.

By following these best practices and being mindful of common pitfalls, you’ll ensure that your use of get_permalink() is both effective and secure. A little attention to detail goes a long way in building reliable WordPress sites. Now that you’re armed with these tips, you can confidently implement get_permalink() in your next project.
