How To Insert Code And Scripts Into WordPress Posts And Pages

Learn how to add code and scripts to content in your WordPress posts and pages.

Inserting Snippets Of Code Into Your PostsOne of the most powerful aspects of using WordPress is that you don’t need to know how to write code to manage a website successfully.

You could come across situations, however, where you may need to insert a block of code into posts or pages in order to add certain functionalities. Useful examples where inserting code snippets into pages or posts may be used to enhance your site include:

  • Current date and time
  • Adding a Google search box
  • Adding a subscription form
  • Display contextual ads
  • Analytics scripts (e.g. Facebook Ads)
  • etc.

Adding code to your pages can give you additional functionality

Some script features can be added through plugins that make handling code easier. In this step-by-step tutorial, we are going to show you how to add snippets of code to your content with and without plugins.

How To Insert Code Into Your Pages - Manual Method

Useful Information

Note: Remember to back up your files and database before adding any scripts or code to WordPress. If you don’t want to perform manual backups, then consider using the services of a professional WordPress provider, or use WordPress backup plugins.

Useful Info

In WordPress, you cannot add code and scripts directly into the visual editor …

Pasting scripts inside the visual editor does not work

(Pasting scripts inside your visual editor does not work)

You can, however, add simple code to WordPress using the text editor. To add code to a post or page, do the following:

First, find or create the code you want to add to your content. You can use a web-based HTML editor (e.g. search online for “Easy HTML Editor“) or use HTML cheat sheets

You can use a free web-based HTML editor or HTML templates to create your HTML code

(You can use a simple HTML editor or HTML templates to create your code. Image source:

Highlight and copy all of the code to your clipboard …

Select and copy the code to your clipboard

(Select and copy your code to the clipboard)

Next, open your post or page and in the Visual Editor, insert a blank line and add a placeholder (e.g. @@@@@) where you would like your code to appear in your content …

(Preview and test any code added to pages)

To learn more about using basic HTML in WordPress, refer to this step-by-step tutorial:


While the above can be used to add simple HTML code to your content, this is not recommended for pasting complex code directly into your content (e.g. lead capture forms, etc.) …

Don't use the text editor to add JavaScript code ... use the methods below instead!

(Don’t use the text editor to add complex code)

Pasting JavaScript code directly into the WP text editor could cause errors.

We recommend using a plugin that automatically processes code using ’shortcodes’ placed into your content.


A ‘shortcode’ is a simple bit of code that allows you to perform complex functions with no coding skills. Shortcodes are typically added to posts, widgets, and pages to trigger a complex script into action.

A shortcode normally looks like a short string of text enclosed by square brackets, e.g. ‘[ezformshortcode]’ …


(What a shortcode looks like)

Shortcodes enable plugin developers to create complex scripts such as user forms, image galleries, content formatting tools, etc., which you then insert into your content using a short text string.

How Shortcodes Work

How to use shortcodes

(How shortcodes work)

The screenshot above explains how WordPress shortcodes work:

[1] You install a plugin that lets you paste snippets of code into a special field (see the tutorial below for an example)

[2] After pasting the code into the field and saving, the plugin creates a unique piece of text that will process this script.

[3] After adding the shortcode to your content, publish or update your page.

[4] WordPress will now automatically call up your function when someone comes to your site.

The great thing about using shortcodes is that you don’t have to mess around with the actual script to get the functionality you want … simply add the shortcode where you would like the script to appear and WordPress does the rest!

How To Add Snippets Of Code To WordPress Content Using Plugins

In the examples below, we explain how to insert code snippets into WordPress using various free WordPress plugins.

Insert HTML Snippet

Insert Html Snippet Plugin For WordPress

(Insert HTML Snippet WordPress Plugin)

As the name suggests, Insert HTML Snippet lets you easily embed HTML code into a post, page, or a sidebar widget.

Essentially, this plugin lets you create HTML snippets and add them to your pages and posts using shortcodes or custom fields.

HTML snippets can store code for just about anything: calculators, forms, tracking codes, etc.

The tutorial below shows you how to add code to your pages and posts using Insert HTML Snippet.

How To Add Code Snippets To Your Content – Tutorial

Download the plugin here, or locate and install the plugin directly from your WordPress dashboard (search for keywords like “Insert HTML, Insert HTML Snippets, etc.“) …

Install 'Insert Html Snippet'

(Locate and install ’Insert Html Snippet’)

Next, activate the plugin …

Activate 'Insert Html Snippet'

(Activate the ‘Insert Html Snippet’ plugin)

After the plugin has been installed, a new item called XYZ Html will be added to the dashboard menu …

Insert Html Snippet - Add a new Snippet

(Create a new Snippet)

This creates, saves, and publishes a new HTML Snippet as a shortcode

You can also create a snippet without having the script code. This is handy if, for example, you are awaiting approval of the code but need to create the content where your code will eventually show up.

In this case, go ahead and create the new snippet with some placeholder content and insert the shortcode into your pages then publish. Once your script has been approved, you can then edit the snippet and replace the content …

You can also create a snippet without having code.

(You can also create a snippet without having your code yet.)

After creating your HTML Snippet the plugin stores it in a separate list in the plugin’s database. You can view all of your stored snippets and shortcodes by selecting XYZ Html > HTML Snippets from your dashboard menu …

Click on the XYZ Html > HTML Snippets plugin menu to view all of your snippets

(Click on the XYZ Html > HTML Snippets menu to view all of your snippets and shortcodes)

A table of all the code snippets you have created will appear in the ‘HTML Snippets’ admin screen …

Snippets table

(Table of snippets and shortcodes)

Because the plugin stores all snippets in a separate database, you can insert one shortcode into multiple pages and control everything from one location. If you update your code snippet, the code will automatically be updated in every instance where the shortcode has been embedded.

You can add shortcodes to your content inside the WordPress visual editor.

To place the code into your content using a shortcode, simply go to your page, widget, or post and select where you would like your code added …

Useful Info

You can deactivate, edit, and delete your snippets …

Deactivate, delete, and edit code snippets

(Edit, delete, and deactivate your snippets)


  • If you delete or deactivate a snippet but leave the plugin active, the shortcode will not display in your content. The plugin will fix your pages so that no content gaps will be noticed by visitors.
  • If you deactivate the plugin, your shortcode will show up in your content.

If you deactivate the HTML Snippets plugin itself, the shortcode will show up in your content

(If you deactivate the plugin itself, your shortcode will display as a line of text in the content)

Tip #2 (Advanced Users): The plugin also uses WordPress Custom Fields to insert code into your content.

Tip #3 – Use WordPress Themes With Drag And Drop Page Building Plugins

Many WordPress themes can be used with drag and drop page-building plugins like Visual Composer or Thrive Content Builder that include built-in script processing features …

(Some themes come with built-in code adding features)

(Some WordPress themes provide built-in code adding features)

Tip #4 – Adding code to the header section of WordPress

With a plugin like EmbeditPro, you easily insert scripts and code into content inside your pages and posts.

Some applications (e.g. analytics and ad conversion tracking tools), however, require code to be added not only to content but also to areas like page headers, footers, etc. (for example, landing pages, opt-in confirmation pages, and so.)

There are a number of WordPress plugins that allow you to add code to the header or footer section of pages. Many of these plugins, however, will add code to all pages, not just the ones you want (check the plugin’s settings – some plugins and themes will add code to all pages and then let you turn the code off on selected pages and posts).

If you need to add code or scripts outside of regular content areas, then you will need to either customize your site or use a plugin like the one below.


The next section is for advanced users. If you need any help modifying scripts on your site, please contact a professional WordPress web developer.

Tip: Checking If You Have Added Scripts Correctly

Some scripts will ask you to verify if you have added the code correctly and some will not.

If you have pasted code into an area like the “header” that is not meant to be visible and you would like to check if the code has been added correctly, then do this:

Viewing Hidden Code In Firefox

First, open up your internet browser (we’ll use Firefox in this example) and go to the page containing the code.

Select Tools > Developer > Page Source from the browser menu …

How to view hidden page code in Firefox

(Tools > Developer > Page Source)

A new window opens with the page code displayed.

Use the search function (Ctrl+F) or scroll down until you can spot the code that you have added (code added to a page header is typically located  between the <head> and </head> tags) …

How to view your code

(Page code)

If you can see the code in your page, then all that’s left is to test your script and make sure that everything is working correctly. If you experience any errors, repeat the process to make sure that you have inserted the code correctly, or get help from a professional. As stated earlier in this tutorial, always back up your files and database before doing anything that involves changing code.
