Auto Refresh Clients on post update/new post

  • Hey all

    I have a monitor running, showing the front page of the blog (I run the wordpress backend locally) – I would like this to work similar to a live update/blog, but I dont know how to automatically update the clients when changes are made to the post.

    Is there away to make clients update automatically, on new posts/updated content? As said the wordpress runs locally so I can make some custom changes, I am just not sure where to start.

    Can you help me?

    Cheers
    Marcus

  • Hi there,

    There is an action you can hook into right after the post has been saved:

    add_action( 'save_post', 'run_my_function' );

    What you could do here is send out an email to your users when you add/update your posts using this action.

    See here for reference to the action:

    I had a look at it, but I am not sure it makes sense in this case. If I add the action to my index.php, It would be triggered when I create a new post using the wp-admin tool?

    I’ve started looking into the post.php in the wp-admin folder, to see if I can run some code when the post is created, that maybe can help me. I am not sure yet

    I have found the code that is called when a post is created or edited in the wp-admin. I have tried to make a cURL request from there, but it seems like it does not get called.

    I dont get any error message, but my server it not reached. Is there anything that could prevent a curl call from being executed?

    Or is there a helper function somewhere in the wp-admin code for making a http request, that I could use?

    It’s possible cURL is not enabled on your particular server, it’s not a module always loaded by default. WP offers the HTTP API for your use.

    That said, and maybe I’m misunderstanding, but I don’t see what you would be requesting via HTTP from a client. For a client to pick up new posts, an easy solution would be to add a meta refresh tag to the page so it simply reloads the page at a particular interval. The browser should then just make a HEAD request to see if anything has changed, and if not, the local cached version is used, so there shouldn’t be a huge sever load by doing this.

    A more customized approach is possible to further reduce server load by having the client do a custom request that queries for the latest post date (preferably without loading the WP environment). If the latest post date is later than the one on the client page, a full page reload could be invoked, unless you want to play around with AJAX requests that just insert the latest posts into the current content.

    Actually it is because my setup is a bit special (I suppose wordpress is not really what should be used for this), and Im just trying to hack something together. That said I actually made it work yesterday, but it is way to complex/overengineered.

    Your solution is actually a good simple strategy, I will try it out a bit later today. Cheers!
