How to show your calendar on external sites using an iFrame

October 19, 2021

The EventON plugin does not yet have an API to allow embedding calendars on external sites. However, you can work around this by making use of an iFrame. Let us walk through the steps that you’ll need to take:

Step 1:

Log in to your FTP client and locate your current theme folder. If your site is currently running the Twenty Twenty One theme, then the path to this theme would be: …/wp-content/themes/twentytwentyone/

Step 2:

Create a new PHP file and call it eventon-iframe.php. Next, open this file using a text editor.

Step 3:

Copy the code below and paste it into the newly created PHP file:


On line 3 of this code, we are requesting a core WordPress file wp-load.php and the path to this file may change if you are using a child theme or if you are using a custom directory structure. Please ensure that you update the path to this file in case it is not on the location shared on the above code.


In case you are interested in customizing the shortcode that will be used in this logic, you can do so by modifying line 21 of the snippet above.

Step 4:

Head over to your homepage and append the path to the file we created above. You should do this after adding the trailing slash to the homepage URL. Here is an example:


The result should look like so on the browser:


Click enter and you should see your EventON calendar displayed with 100% width on this page.

If you see the EventON calendar and it works great you are good to go to the next step. If not, you may see some errors on the page that may be related to an incorrect path or a missing file. Try to address those errors or you can start over in case you missed a step.

Step 5:

Now go to your external site where you want to show your EventON calendar. Find the page you want to show the calendar and add the HTML code shown below:

Make sure you are entering this into the HTML tab and not the text tab in your WYSIWYG editor

NOTE: You can customize the height and width of your iframe by modifying the height and width attributes. We recommend ensuring the scrolling attribute to yes to accommodate slide-down styles on the calendar.


You can get even more creative with the iFrames by using CSS styles to make it look fancier.

Step 6:

Once you publish that page or save changes the EventON calendar should work perfectly inside the iFrame on your external website.


Happy iFraming!
