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 …

How To Insert Code And Scripts In WordPress Posts And PagesOne of the best reasons for using WordPress is that you don’t need to know how to write code to successfully manage a website or blog.

There may be instances, however, where you may decide to paste a script or code snippet into content in order to add desired functions or features. Some common examples where inserting snippets of code into pages would add functionality to your site include:

  • Today’s date
  • Adding a Google search box
  • Adding a subscription form
  • Display contextual banner ads
  • Conversion tracking code (e.g. Google Adwords)
  • etc.

Adding code to content can give you additional functionality

In this step-by-step tutorial, you will learn how to easily embed scripts into WordPress posts and pages with and without plugins.

Inserting Simple HTML Code Into WordPress Pages And Posts Using The Text Editor

Important Info

Note: We recommend backing up your files and database before adding any scripts to WordPress. If you don’t want to perform your own backups, then get assistance from a WordPress professional, or use backup plugins.

You can read about a WordPress backup plugin that can fully automate your backup process here:


Scripts cannot be pasted directly into the WordPress visual editor …

Pasting code inside your 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, locate or create the code you would like to add to your content. You can use a web-based HTML editor (e.g. search online for “Free Online WYSIWYG HTML Editor“) or use HTML templates

You can use an online HTML editor or HTML templates to create your code

(Use a web-based HTML editor or HTML templates to create your HTML code. Source:

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

While the above method is fine for adding simple HTML to your content, this is not recommended for pasting scripts containing JavaScript code directly into your content (e.g. opt-in forms, etc.) …

Don't use the text editor to add Javascript code

(Don’t use the text editor to add Javascript code … use other methods instead!)

Pasting complex directly into the WP text editor can lead to errors.

We recommend using a plugin that automatically processes snippets of code from ’shortcodes’ pasted into your content.

What Is A Shortcode?

A ‘shortcode’ is a simple bit of code that allows you to perform complex functions with no coding or programming knowledge. Shortcodes can typically be used in pages, widgets, and posts to trigger complex scripts into action.

Shortcodes normally look like little bits of text enclosed in square brackets, e.g. ‘[ezformshortcode]’ …

What a WP shortcode looks like

(What a shortcode looks like)

Shortcodes allow WordPress developers to create complex scripts such as image tools, content formatting tools, forms, etc., which you then add to your content via a short text string.

How A Shortcode Works

How to use shortcodes

(How shortcodes work)

The screenshot above explains how to use shortcodes:

[1] First, install a plugin that allows you to paste code snippets into a special field (we’ll show you an example of this in the tutorial below)

[2] After pasting the code snippets into the special field and saving, the plugin creates a unique shortcode for calling up the script.

[3] Copy the shortcode and paste it into a new or existing post, page, or widget where you would like the function to display and publish.

[4] WordPress will now automatically process the script.

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

Embedding Snippets Of Code Into WordPress Posts And Pages Using Plugins

There are various plugins that let you insert code into your WordPress widgets, pages, and posts.

Insert Html Snippet

Insert Html Snippet - WordPress Plugin

(Insert Html Snippet Plugin)

As the name of this plugin suggests, Insert HTML Snippet lets you easily insert snippets of code into pages, posts or sidebar widgets.

How this plugin works is that it lets you create HTML snippets and add them to your pages and posts using shortcodes or custom fields.

HTML snippets can store codes and scripts for just about everything: calculators, javascript codes, etc.

The tutorial below shows you how to use Insert Html Snippet.

How To Insert Code Snippets Into Your Content – Insert Html Snippet Plugin Tutorial

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

In this case, go ahead and create a snippet with placeholder content and insert the shortcode into your content then publish. After your code has been approved, you can then edit the snippet and replace the content …

You can create a new shortcode without having your code snippet yet.

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

Click on XYZ Html > HTML Snippets to view a list of all your shortcodes

Because the plugin keeps all snippets stored in a separate database, you can use the same snippet in multiple pages and control everything from one location. If you edit your code snippet, whatever is controlled by the snippet will automatically be updated in every instance where you have added the shortcode.

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

To place the code into your content using a shortcode, simply open your post or page and place your mouse cursor where you would like to insert the code …

Tip #2 (Advanced Users): EmbedIt Pro also uses WordPress Custom Fields to add code to your content.

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

Most WordPress themes can be used with drag and drop page-building plugins like Visual Composer or Thrive Content Builder that have built-in code processing functionality …

(Some WordPress themes offer built-in code insertion functionality)

(Some themes offer built-in features)

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

A plugin like EmbeditPro allows you to easily insert snippets of code into content inside your pages and posts.

Some applications (e.g. analytics and banner ad tracking tools), however, require code to be added not only to content but also to areas such as headers, footers, etc.

You can find a number of plugins that will allow you to add code to the header section of posts and pages. Many of these plugins, however, add code to all posts and pages, not just the ones you want (some plugins will add code to all pages and then let you turn the code on/off on selected pages).

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

Tip: How To Verify That Your Code Has Been Added 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 that is not meant to be visible (like the ”header” section) and you would like to check if the code has been added correctly, then here’s how to do it:

How To View Hidden Code In Firefox

First, open up your internet browser (we’ll use Firefox in this example) and visit the page that contains your code.

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

Viewing page code in Firefox

(Tools > Developer Tools > Page Source)

A new window opens up with the source code displayed.

Use the search function (Ctrl+F) or scroll down the screen until you can see the code that you have added (if adding code to a page header, it will typically be located  between the <head> and </head> tags) …

How to check that scripts have been added correctly

(Verify if you have added your code correctly)

If you can see the code, then all that’s left is to test your script and make sure that everything is working correctly. If you experience any problems, repeat the process and make sure that your code has been inserted correctly, or get a professional to help you. As stated at the beginning of this tutorial, always back up your files and database before adding, changing or deleting code.
