[Picture Guide] How To Add MailChimp Optin-Box To Your WordPress Sidebar

With the new version of WordPress, adding HTML to a sidebar widget is easy. In this post, I will show you step by step instructions to put MailChimp form into your sidebar. You can do this with other email marketing services too. The key is to get the HTML code of your form.

The step by step guide

Step 1: Login to your account

First of all, please login to your MailChimp account

Here, I’m in my account dashboard. Now, look at the top menu, you will see a menu item called Lists. Click on that.

Step 2: Select your list

A list is a collection of your subscribers. For example, you are a sleep instructor. Your audience are interested in sleep training. However, instead of putting all the people in one big list, you can split them into multiple lists to make it easier to manage. Here, as you can see I have two lists: Time Management Tips and Software. I select the Time Management Tips list.

Now, notice that at the right side of each list, you will see a dropdown, click on that and select Signup forms.

Step 3: Get the HTML code of your form

Here, you will see the form editor. You can add or subtract the fields if you need to. Then, copy the part under the title Copy/Paste onto your site

Step 4: Go to your Widget area

You may go to this area before. It’s under Appearance->Widgets

Step 5: Add a custom HTML widget to your sidebar

Your theme could have one or more places for you to put the widgets. Those areas called sidebars (though sometimes you will see they appear at the footer). As you can see in my site here, I have one sidebar at the left and 4 areas in the footer.

I’m going to drag and drop a Custom HTML into the sidebar.

Step 6: Put the HTML code of your form into the widget

Now simply paste the HTML code into the Content box. You can give it a title (it will display as a h3 above your form). I don’t put anything this time.

Now click on Save and then Done.

Step 7: See your form

As you can see, the form is now on the left sidebar.

How To Use Visual Composer In The Category Page

Visual Composer is a very popular plugin to visually create your content. There are many widgets, components in the plugin. In addition, there are other plugins that add more functionalities and widgets to Visual Composer make it the love of many WordPress users.

However, Visual Composer can only be used on regular pages/posts. If you want to use it to create content for your category page, you are out of luck. Visual composer doesn’t support creating content for the category page.

In case you don’t know where to put content on your category, here it is:


As you can see, there is a text editor for you to put the content, descriptions for the category but that’s it. There is no visual composer editor available.

So, how can you enable visual composer in the category page?

Meet the plan

Our plan is quite simple. Instead of putting the content directly into the editor of the category page, we will create a draft post and then display the content of that draft post as the content of the category page.

Why a draft post?

Because you don’t want your visitor to see this post since it’s not a independent post by itself. The sole purpose of this post is to contain the content for the category page.

As a post, you can use all the features of Visual Composer to compose its content.

Let’s look at a diagram, shall we?

Now, let’s get to the step by step implementation.

Step-by-step to use Visual Composer to create content for your category page

  1. Create the content of your category page in a regular post using Visual Composer
  2. Save that regular post as a draft
  3. Get the draft post’s ID
  4. Install Display Posts Shortcode plugin
  5. Find out what theme your site is using
  6. Create a template file for your category page
  7. Display the content of the draft post in your category using shortcode

I assume that you are familiar with the steps 1 and 2. Creating a post and save it as a draft are quite trivial so I won’t explain in details here.

Step 3: Get a post’s ID

After creating the draft post, make sure you get the post ID and save it somewhere. You can get the post ID of any post by following the instructions below:


Step 4: Install Display Posts Shortcode plugin

You can navigate to Plugins->Add new and search for this term: Display Posts Shortcode and install the one as in the image below:


Step 5: Find out what theme your site is using

This step is quite simple, please go to Appearance->Themes and you will see what theme is currently active. We need to know this information for the next step.

Step 6: Create a template file for your category page

This step sounds scary for people who don’t know how to code. However, it is very simple. You need to access to your themes folder on your server to complete this step. You can access the files via cPanel or FTP or ssh. Please ask your hosting provider for those details. All hosting providers should have no problem sending you those details.

Here I use Filezilla FTP client to access my files. Please go to wp-content/themes on your sever.

In the previous step, I found out that my site is currently using the theme Blog One, I can see the folder of that theme here:

I will click inside that folder to see all the files:


Here, we pay close attention to the one file called single.php. We are going to create a template file for the category using that file.

Now, go find your category ID. The method is similar to finding post’s ID.

  1. Go to Posts->Categories
  2. Hover on the Edit link of your category
  3. Look at the status bar of your browser (bottom left)
  4. Locate the tag_ID value

And that’s your category ID.

For example, my Blog category ID is: 1


Now, copy the single.php file and name it category-1.php (if your category ID is 300, you need to create a file called category-300.php);


If you use an FTP client such as FileZilla, you need to download the single.php to your computer first, then rename the file to the new name.

Open the file with your favorite text editor. On Mac, you have Sublime text. I use Notepad++ since I’m on Windows.

Your file may be a bit different, however, it will look something like that.

Now, we need to remove the content of the file from the <?php to ?> in the image above:

Then, put the following code right at the place where you have just removed the old content:

Make sure you replace the your_draft_post_ID with the actual draft post ID you got from above.

Now, upload the file to your theme folder (sample folder with the single.php) and you are done.

Now, what you put in the draft post will appear on your category page.

One last thing, please NEVER publish the draft post.

I hope this post has been helpful. Now you can use Visual Composer to create content for your category page.

How To Install WordPress Plugins, Themes From URL

Sometimes you need to install plugins, themes. Maybe for yourself, maybe for clients. Many times, you see this error:

The common way to fix this problem is to use FTP upload or access via cPanel. However, many times we don’t have that luxury.

So, this plugin I created based on the the other plugin WP Developer Assistant (An awesome plugin that saved my life countless times but the author haven’t updated for years and it’s not working with php 7). It has one function: allow you to upload files to folders on your servers without touching php.ini, without having access to FTP…

The UI is simple and straightforward. If you don’t know how to use, please let me know.
