I'm running WordPress 2.7, Events 1.6.1, and TinyMCE Advanced 3.2. A client wanted to be able to format the text in the event description. To accomplish this, I replaced the the_event_editor() function in wp-events-manage.php with the following code:
function the_event_editor($content, $dashboard = true) {
wp_admin_css('thickbox');
wp_print_scripts('jquery-ui-core');
wp_print_scripts('jquery-ui-tabs');
wp_print_scripts('editor');
add_thickbox();
wp_print_scripts('media-upload');
if (function_exists('wp_tiny_mce')) wp_tiny_mce();
if(user_can_richedit())
wp_enqueue_script('editor');
echo "<div id='editorcontainer'><textarea rows='6' cols='20' name='events_pre_event' tabindex='4' id='content'>" . $content . "</textarea></div>";
}
This displays the rich text editor with the buttons specified through the TinyMCE Advanced plugin.
