[wp-hackers] Pseudo-Cron

[Martin at Cleaver.org]

Instead of

wp_schedule_event(time(), 'hourly', 'my_hourly_event');

A helpful syntax would be:
wp_schedule_event(0, 'hourly', 'my_hourly_event');

If you use 0 you end up with a stuck event in the table.

I know this because I built a dashboard viewer for cron entries. It'd be
neat if it could become bundled and turned into a cron entry editor.

        return $s;

add_action('admin_menu', 'wp_cron_add_pages');

function wp_cron_menu() {
        $format = "%X %x";
        print "<table>";
        print "<tr><td>Now<td>".strftime($format,time())."</td></tr>";
        print "</table>";

        global $wp_filter;
        print "<pre>";
        print mrjc_show_cron_schedules();
        print "</pre>";
}

function mrjc_show_cron_schedules() {

  $timeslots = _get_cron_array();
  if ( empty($timeslots) )
    return $ans+"Nothing scheduled";

  $ans = '';
  $count = 1;
  foreach ( $timeslots as $time => $tasks ) {
    $ans .= "Entry #$count: Anytime after ".strftime("%c",$time)." execute
tasks:";
    foreach ($tasks as $procname => $task) {
      $ans .= $procname." ";
      $count++;
    }
    $ans .= "\n";
  }
  return $ans;

}
