What You’ll Have to Automate WordPress Navigation Menus

To comply with together with this put up, you’ll want:

A growth or testing set up of WordPress, with some pages and subpages added, and
A code editor.

The entire code is on GitHub so for those who get caught, you possibly can interrogate that to see what you need to be doing.

Organising the Code

I’m going so as to add this code to a plugin in order that I’ve nonetheless obtained it if I ought to change my theme in future. That manner, I can then code the operate from my plugin into my theme so as to add the navigation menu or part menu in the correct place. In case your theme has hooks, you may use a number of of these so as to add your code.

If you happen to’re working with a 3rd get together theme that doesn’t have hooks, you’ll have so as to add code to the theme. Don’t code this instantly into the theme: as a substitute, create a toddler theme and add your code to that. Simply make a reproduction of the theme template file from the mother or father theme that you simply need to edit, add that to your little one theme and edit it.

Step one is to create the plugin. I’m making a folder for mine in my wp-content/plugins folder. Making a folder means I can add extra recordsdata to the plugin in future if I have to, similar to a stylesheet or embody recordsdata.

First it’s essential add the opening code to your plugin, in feedback, to inform WordPress what that is:

Now activate your plugin.

Subsequent, for those who’re utilizing a toddler theme, set that up. I’m utilizing a toddler of the Twenty Seventeen theme – right here’s my stylesheet:

When you’ve performed this, in case your website doesn’t have already got some pages in it, add some. They should have a multi-level construction. Listed below are my dummy pages:

Now let’s begin including the code to the plugin.

Making a Perform to Checklist All Pages Hierarchically

We’re going to make use of the wp_list_pages() operate to fetch all of the pages and checklist them out with hyperlinks. However first we have to outline some arguments for that. Begin by creating your operate and together with the arguments:

The arguments are quite simple – there’s only one for the extent of pages we need to go all the way down to. Setting this at 2 signifies that prime stage pages and their sub pages can be displayed, however nothing decrease down.

Now let’s add the wp_list_pages() operate after the arguments:

Right here’s the total operate:

Including the Perform to the Theme

Proper now, the operate doesn’t present something anyplace on my website. To alter that, we have to add a duplicate of the header from the mother or father theme to the kid theme and edit that.

Begin by duplicating your header file into your little one theme and open it. In twenty seventeen the code for the navigation menu is in template-parts/navigation/navigation-top.php which suggests I want so as to add a duplicate of that file in the identical location in my little one theme, in order that it’s referred to as appropriately from the header.php file. In your theme it could be the header.php file itself that you must copy.

Relying in your theme, the code for the menu can be completely different. In twenty seventeen, that is the code I want to exchange:

Edit your nav menu code so as to add a brand new operate, with the prevailing code inside an else{} assertion:

The conditional statements are vital: first it checks if the operate you added to your plugin is current (i.e. if the plugin is activated) and if that’s the case, it runs the operate from that. If not, it runs the nav menu as regular.

Now let’s check out my website:

The hyperlinks are displaying up however there are a few issues. I don’t need it to say ‘Pages’ on the prime (which is the default for the wp_list_pages() operate) and I need to order the pages extra successfully. You’ll see that the house web page is in the midst of the checklist, which isn’t supreme.

Bettering the Perform

Let’s return to the plugin code and tweak it to repair these issues.

Discover the arguments you already outlined for wp_list_pages():

And edit it:

This provides two further arguments:

The markup earlier than the checklist, which now says ‘Menu’ as a substitute of ‘Pages’.
The order by which the pages are displayed.

You could return to the enhancing screens on your pages and set the web page order for every of them. Give your private home web page a price of 0 and the opposite prime stage pages values increased than that.

Now if you view the menu it is going to seem like this:

You may also alter the menu order of the second stage pages. These won’t ever show above prime stage pages so you can begin at 0 or 1 for every set of sub pages. It’s a good suggestion to not make these numbers subsequent, so you possibly can slot further pages in in future if you wish to.

Nested menu displaying first and second stage pages.

Automating Your Navigation Menus Can Save Work and Minimise Errors

In case your website is completely page-based, then utilizing this method will prevent including new pages to the menu if you create them. If you happen to’re growing a website for a consumer and also you’re undecided they’ll have the abilities or the boldness to edit the navigation menus, then it future proofs the location and minimises the chance of error. You have to to indicate your consumer tips on how to set the menu order for brand spanking new pages, however you received’t want to show them the menus performance.

And for those who don’t need to use this in your principal navigation menu, you may at all times use it in your footer or after your content material as a substitute. This manner your website guests have someplace to go after they’ve completed studying every web page.
