Display the calendar manually

This plugin doesn’t support a shortcode or a function to call manually, so you may find some troubles if you use more than one TheLoop on your page. I guess I’ll share with you what I’ve done to overcome this.

Now before reading on, note that there’s already a topic here about using shortcode. When this method may work, it requires editing the plugin files, which is a big no-no.

OK now this is how the calendar is being output (as of version 1.10.5):

1. File app/controller/class-ai1ec-app-controller.php line 492:
add_filter( 'the_content', array( &$this, 'append_content' ), PHP_INT_MAX - 1 );

2. And at line 530:

function append_content( $content )
	{
		// Enclose entire content (including any admin-provided page content) in
		// the calendar container div
		if( in_the_loop() )
			$content =
				'<div id="ai1ec-container" class="ai1ec-container timely">' .
				$content . $this->page_content .
				'</div>';

		return $content;
	}

Basically, the plugin hooks into the_content() function and inject the calendar output there. With this approach, if you have multiple WP_Query on the page, the first the_content() call will have the calendar attached, which is not necessary what you may need.

These steps can be done to “fix” this approach:

1. Remove the filter, so that the calendar is not automatically populated. Put this into functions.php or at the beginning of your template:

remove_filter('the_content', array(Ai1ec_App_Controller::get_instance(), 'append_content'), PHP_INT_MAX - 1);

2. Manually store the calendar output into a string. Use this code for the first Loop on the page:

if (have_posts()) {
	the_post();
	the_content();
	$calendarContent = Ai1ec_App_Controller::get_instance()->append_content('');
}

3. Now we have the calendar string in a variable. A normal <?=$calendarContent?> can be used to output it anywhere.

Hope this helps someone.
