Do you want to allow PHP in your WordPress posts and pages?

By adding custom code to your site, you can fine-tune WordPress to better suit your needs. However, by default, WordPress does not let you add PHP directly to your pages or posts.

In this article, we will show you how to allow custom PHP in WordPress posts and pages.

Why Allow PHP in WordPress Posts and Pages?

If you try typing PHP code directly into the WordPress block editor, then you will notice that WordPress strips away a lot of your code or even deletes it entirely.

WordPress doesn’t allow PHP in posts and pages for security reasons. This is because a simple mistake in your PHP code can cause all sorts of common WordPress errors.

However, there are some cases where adding PHP to WordPress posts and pages may be necessary.

For example, if you make money through affiliate marketing, then you might need to add advertising code to your site.

You may also want to develop your own PHP functions to replace the need for certain WordPress plugins. This may be necessary if you think installing a plugin for just one function seems like an overkill.

You can learn more about this topic in our article about WordPress plugins vs functions.php.

With that being said, let’s see how you can allow PHP in WordPress posts and pages.

Allowing PHP in WordPress Posts and Pages

The easiest way to allow PHP code in WordPress posts and pages is by using WPCode. This plugin allows you to create as many code snippets as you want and then add them to your desired post(s) or page(s).

You can learn more about the plugin in our WPCode review.

The first thing you need to do is install and activate the free WPCode plugin. For more details, see our step-by-step guide on how to install a WordPress plugin.

Upon activation, head over to Code Snippets » Add Snippet.

How to add a shortcode in WordPress

Here, you will see all the ready-made snippets you can add to your website. These include snippets that allow you to completely disable WordPress comments, upload files that WordPress doesn’t support by default, and more.

Since you are creating a new snippet, you need to hover over ‘Add Your Custom Code.’ Then, click on ‘Use snippet.’

Adding custom PHP to WordPress

To start, type in a title for the custom code snippet. This can be anything that helps you identify the snippet in the WordPress admin area.

After that, open the ‘Code Type’ dropdown and select ‘PHP Snippet.’

In the code editor, simply either type in or paste the code that you want to use.

After that, scroll to the ‘Insertion’ section.

WPCode offers two ways to insert PHP in pages and posts: by choosing a page-specific location or through shortcodes.

Choosing between Auto Insert or Shortcode insert methods in WPCode

Let’s explore each option one by one:

Inserting PHP Codes in a Page-Specific Location

If you choose the ‘Auto Insert’ method, you can select the ‘Page-Specific’ option and choose where to insert the PHP code snippet.

It can be before the post content, after it, before a specific paragraph, and so on.

Page-specific location options to insert custom code snippets in WPCode

This method is recommended if you want to add custom PHP code in all of your pages and/or posts at once. Once you have chosen a location, you can click on the ‘Inactive’ toggle so that it changes to ‘Active.’

Finally, click on ‘Save Snippet’ to make the snippet live.

Saving custom PHP snippets in WordPress

Now, if you only want to add PHP code snippets in individual pages or posts, then we recommend the shortcode option.

Inserting PHP Code Snippets Using Shortcodes

Since we want to insert custom PHP using shortcode, click on ‘Shortcode.’ WPCode will now show the shortcode that you can add to any page, post, or widget-ready area.

Allowing PHP code in WordPress pages and posts

Pro Tip: If you upgrade to WPCode Pro, you can create a custom shortcode. This feature will come in handy if you have created multiple shortcodes and need to differentiate them.

After that, just make the code snippet active and click ‘Save Snippet.’

Once you have done that, you are ready to add the custom PHP to your WordPress website by opening any page or post.

In the block editor, simply click on the ‘+’ button and type in ‘Shortcode.’ When it appears, select the Shortcode block to add it to the page or post.

How to add a shortcode block to WordPress

You can now paste the shortcode into this block. For more information, please see our beginner’s guide on how to add a shortcode in WordPress.

When you are ready to make the code live, either publish or update the page. Now, if we visit our website, then we will see the shortcode in action.

How to Manage Your PHP Code Snippets

Now that you know how to create custom PHP code snippets, let’s learn how to manage them properly.

To do that, simply go to Code Snippets » Code Snippets.

Enabling and disabling custom PHP code in WordPress

At some point, you may want to remove a custom PHP snippet from your entire website. In this case, you can deactivate the snippet, as this will disable it for every page or post.

To do this, you can just find the code that you want to deactivate and click on its toggle to turn it from Enabled (Blue) to Disabled (Grey).

After that, it’s a good idea to visit your website and check that the deactivated code isn’t causing any problems. If you use the shortcode method, you also need to make sure that all of the shortcode block instances have been removed.

Let’s say you have many code snippets and find that some have been deactivated for a long time. If you won’t be using them any longer, then you can delete them to remove any unnecessary code snippets on your site.

Simply hover over the snippet that you want to delete and then click on ‘Trash’ when it shows up.

    Put something like this in your template to create a javascript var to store the path, then use javascript to write it in your content?

    (removed some chars so this will show up –

    var templateDir = “<php bloginfo(‘template_directory’)>”;
