If you’re looking to get the permalink by the slug, then you need to know two things:
So with that said, let’s assume that there’s a page that has the slug: “Register For This Site.” Since the slug is often the page’s title, we can write the following function:
function theme_get_permalink_by_title( $title ) { // Initialize the permalink value $permalink = null; // Try to get the page by the incoming title $page = get_page_by_title( strtolower( $title ) ); // If the page exists, then let's get its permalink if( null != $page ) { $permalink = get_permalink( $page->ID ); } // end if return $permalink; } // end theme_get_permalink_by_title
if( null == theme_get_permalink_by_title( 'Register For This Site' ) ) { // The permalink doesn't exist, so handle this however you best see fit. } else { // The page exists, so do what you need to do. } // end if/else
Although we’re technically getting the page’s permalink by its slug, the slug is often synoymous with the page’s title so I tend to prefer to write my functions so they are a bit more readable – title seems to be a bit clearer than slug.
Notice also that I’m performing a strtolower within the theme_get_permalink_by_title function. WordPress will handle the case when it’s lowercase and I always find it a best practice to normalize whatever input the user has provided given the function.

I was surfing the WordPress Ideas forum as I usually do every other day or so when I came across an interesting idea for a plugin.
The idea was for an easy way to link to other posts within the same blog without those links ever being broken (even if you change the page/post slug in the future).
This is easy if you have a PHP plugin installed. You just use the get_permalink() function. I suppose not all folks want to mess around with PHP though.
Anyway, 15 minutes later, I had the plugin running and a few tests done.
As usual, unzip the get-permalink file. Then, upload it to your /wp-content/plugins directory. Activate it from your WordPress dashboard.
The basic syntax is the same as normal hyperlinks, so there shouldn’t be any confusion about how it works.
If you’re just looking for a simple link to a post or page, just add this when writing a post (the 100 is the ID of the post or page):
[permalink href="100"]Hello world![/permalink]The resulting output would be this:
<a href="http://yoursite.com/link-to-post" title="Title of your post" rel="bookmark">Hello World!</a>Well, there’s more you can do, such as define the title, rel, and class of the link. Something like this might suit your fancy:
[permalink href="100" title="Super cool post title" rel="nofollow" class="red-class"]Cool post[/permalink]How about an image?
[permalink href="100" class="alignleft"]<img src="image.jpg" alt="Example image" />[/permalink]Well, it’s pretty useless to me since I always keep a PHP plugin installed and can easily use a WP function for this. Plus, I don’t plan on changing too many permalinks anyway.
You might say, “Why not just link directly to the post’s URL?” That’s fine, but if you ever change your permalink structure or change a page/post slug, then you’re in for some trouble. You’ll have broken links.
What happens if you ever decide to change your domain name but want to keep the same posts? Well, your links are protected with this method.
The post/page ID never changes though. So, if you’re linking directly to the ID, your links will always be safe.
It’s not a plugin for everybody, but some might find it useful.
I don’t think there should be any major problems, but I did write this pretty quickly. So, let me know if you run into any trouble, and I’ll fix any issues.

The get_permalink() function makes it possible for you to retrieve the current post’s permalink. It’s syntax goes like below:
<?php $permalink = get_permalink( $id, $leavename ); ?>
You see that this function takes two parameters, both optional. The first one, $id, is the one which allows you to manually modify the ID of the post, therefore making you able to choose the post whose permalink you want by it. Obviously, the default value of this parameter is the current post’s ID.
The second one, $leavename, is a boolean operator (that takes either TRUE or FALSE values) that defines the structure of the permalink you will get, or specifically, whether to include the post’s name or just keep the page’s name. To make it more clear, let’s suppose we have set this parameter to FALSE. Instead of getting a result similar to http://www.mywebsite.com/current-post, we will get this one: http://www.mywebsite.com/%currentpostname%. The default value for this parameter is FALSE.
We mentioned before that we can use the get_permalink() function to get the permalink of both the current post and also others’. Let’s see how we can do these in real life!
Showing current post’s permalink
The easiest and most straightforward way to use the function is to find out the current post’s permalink. See the code snippet below:
<?php $permalink = get_permalink(); echo $permalink; ?>
As you might notice, it’s just the syntax, we haven’t defined either parameter.
Showing a certain post’s permalink
We can choose the post whose permalink we want by specifying the $id parameter as seen in the code below:
<?php $permalink = get_permalink(16); echo $permalink; ?>
This way, we have required the information regarding the post with the ID 16.
Showing a certain post’s permalink structure
We can find out a specific post’s permalink structure by displaying the post’s permalink with it’s name. Take a look at the code snippet below:
<?php $permalink = get_permalink(16, true); echo $permalink; ?>
If the permalink of the post whose ID is 16 is something like http://www.mywebsite.com/sixteen when we use the code snippet above, then when we use this line of code it’ll be similar to http://www.mywebsite.com/2015/10/sixteen, or whatever permalink structure you already have set.
This was an example of get_permalink in WordPress.

get_permalink retrieves the permalink of current post to the frontend as a variable but does not echo it out like the_permalink function. If a permalink of another post is required then post ID can be passed to the function.
<? PHP
$permalink = get_permalink( $id, $leavename );
?>
There are two optional parameters for this function:
<? php
$permalink = get_permalink(7);
echo $permalink;
?>
<? php
$permalink = get_permalink(5, true);
echo $permalink;
?>
In WordPress, you can easily change the structure of permalinks in the settings sections as shown in the figure below:
The function is used in wp-include/link-template.php, wp-include/embed.php, wp-includes/comment.php, wp-admin/includes/dashboard.php and other files.
The business purpose of using permalinks are to facilitate the search engines and make efficient SEO. The custom structure or post name is the most suitable if you want the site to be SEO efficient.
Prefer underscores (_) to name the posts instead of dashes (-). It will help in SEO. Also use of keywords could help the post in search engine optimization. The most important tip when using permalink is never change them after publishing the post or page. It will affect the traffic at yur website. If it is necessary, then set up a 301 redirection from old URL to new URL via .htaccess. This could also be done via updating the permalinks and saving the file. It will automatically update the .htaccess file.
