There’s a beta version of this plugin which does this, or you can use the current version, plus a plugin I wrote which adds your CPTs. This you can get from my site@ http://www.getupandrunning.net/2010/06/adding-custom-content-types-to-the-sitemap/

Just download and activate it.

You don’t need to edit wp-register.php (you can do almost anything with WP without editing core files), but you do need to be familiar with filters and actions.

Basicially, you want to add your own action after WP has registered your user, and then you can add posts using wp_insert_post (http://codex.wordpress.org/Function_Reference/wp_insert_post).

I think the action you need to hook into is user_register or profile update. Unfortunately, there isn’t much in the way of documentation for these hooks.

So your code might look something like this:

add_action('user_register', 'my_user_register');
function my_user_register($user_id) {
     $my_post = array(
         'post_title' => 'My post',
         'post_content' => 'This is my post.',
         'post_status' => 'publish',
         'post_author' => $user_id
      );
    wp_insert_post($mypost);
}

You’d have to get to grips with building a custom WP_Query(). You may find the various filters useful, particularly, add_filter('posts_limits','my_post_limit_filter'); which you can use to dynamically set your query limit.

As for your links, or drop down, you’d need some custom query parameter, perhaps ?ppp=10 which you can tack onto the page url.

And then finally use some conditional functions such as is_archive() to test when to modify the page limits.

Hope that gives you some pointers.

Hi Pete, the codex page you linked also links to this: http://www.wphardcore.com/2010/5-tips-for-using-ajax-in-wordpress/

Although it is counter-intuitive, you do need to be sending your requests from the javascript to the admin-ajax.php file. The hooks you define will be called from there, and from there your functions will be called.

Example Hooks:

// this hook is fired if the current viewer is not logged in
add_action( 'wp_ajax_nopriv_myajax-submit', 'myajax_submit' );
add_action( 'wp_ajax_myajax-submit', 'myajax_submit' );

The hook/action name is determined by the action field in the ajax request. So if your action is called “myajax-submit” you’d use the two actions above. The second argument is the name of the function to call in your plugin.

If you’ve just put in that code into your functions.php file then yes, it will run with every page load.

The do_action function normally resides inside other functions where and when you want something particular to happen.

Perhaps you want to link into WordPress’ default hooks (you’ll find a nice list here: http://adambrown.info/p/wp_hooks/hook/actions) such as post_updated. All you need do then is use add_action(‘post_updated’,’my_function’) to do whatever funky stuff you want to do.

The arguments are defined by the do_action function as in the example here: http://codex.wordpress.org/Function_Reference/do_action

So somewhere you’d need:

do_action('publish_page',$arg1,$arg2);

And your function should look something like:

function my_function($arg1,$arg2)
{
   // do something with the args
}

And your add_action should be something like:

add_action($hook,'my_function',10,2);

Where the “2” is the number of arguments.

If you’re testing the new official release from @arnee and had installed my custom post type fix, you had better deactivate mine or else the universe may go spiralling out of control.

@chocks It’s not set up to do that. The settings page only lets you set certain types of posts.

In other news: I’ve updated my plugin plugin to honour excluded PostIDs and Categories for Custom Content Types. You can get the update from my site at: http://www.getupandrunning.net/2010/06/adding-custom-content-types-to-the-sitemap/
