Selective caching: Widget on cached page

All,

The documentation about what I’m interested in:

https://wordpress.org/plugins/wp-optimize/#can%20i%20make%20certain%20parts%20of%20the%20page%20stay%20dynamic%20when%20cache%20is%20enabled%3F

Basically, we’re going to have a cached page of our Locations, but would like to include a LIVE ticker of how many people are in each Location at the moment. So would need to somehow exclude that ticker from being cached.

So at the moment if you want to keep parts of your page dynamic (e.g. adverts, widgets, shopping cart…) AND keep it cached, you will have to use custom solutions using javascript and AJAX to fetch those dynamic parts from the server.

Does anyone have an example of how to do this?

Would be so USEFUL to have a working example,

Best regards,

Mark

Hi,

Thanks for contacting us! While I don’t have a working example of something like this that I can share, I wanted to share how I would approach this type of situation to achieve what you’re looking for.
1. First I would determine if the ticker plugin has any REST API Endpoints. If it does then a custom javascript script could be loaded on the front-end to call that endpoint and then update an HTML element that is on the page.
2. If there is no built-in REST API endpoint with the ticker plugin, I would register a WP Rest API endpoint with PHP code that when called will fetch the data from the database or using a PHP function that the ticker plugin might expose and then send that data back to the front end.
3. When registering the custom WP REST API endpoint I would also ensure that there are nonce checks in place for security purposes and if any user input is sent to the API I would ensure to sanitize the data.
4. Once the custom API endpoint is up and running, a small custom javascript script can be written that calls the API and updates an HTML element on the frontend of the site.
If you don’t have any development experience I would recommend engaging with a web developer for this type of task as hopefully it should be fairly straight forward for them to implement this custom functionality on your site.
