[EventCalendar] re: Showing the event post ONLY on the day it occurs

Hi Alessandro. I've run into the same problem. In theory you can  
enter a future post date, the day of your event, and it will not  
appear until that date. However, by default Wordpress won't display  
future dated posts to anonymous (non logged-in) users so when they  
click on a link to see a future dated event they instead get a "no  
matching item" message. Previously there was a hack to Wordpress to  
work around this but Alex has (rightly) decided its a Wordpress issue  
and should be dealt with as such.

There is a simple plug-in called Future Posts:

	http://www.figby.com/archives/2005/04/12/wordpress-15-plug-in-view- 
future-posts/

that is supposed to fix this exact issue but so far I haven't been  
able to get it to work, at least on the latest Wordpress version on  
my site. There are hints on fixes it in the comments on that page but  
even after correcting for mangling of the posted code it still isn't  
working.

It operates by adding a filter to the SQL commands used to fetch  
entries that removes the clause that specifically checks that the  
post date is <= the current time. I've verified my modified and  
simplified version of the plug-in is in fact doing that, but the  
posts still don't appear for anonymous users.

Here is my test plug-in (between the // ----- comment lines.) The  
original version had several options but for testing I've hard-coded  
it to assume what I want: show future posts when they are viewed as a  
single item. It is saved as futureposts.php, placed in the plug-ins  
folder and activated:

// ----- futureposts.php:
<?php

function wp_future_posts_plugin($content)
{
     if (is_single())
	$content = preg_replace("/ AND post_date_gmt <= \'.+\'/", "",  
$content);
     return $content;
}

add_filter('posts_where', 'wp_future_posts_plugin');

?>
// -----

Not a whole lot to it. The preg_replace line is the key, it matches  
the portion of the command that excludes future posts and replaces it  
with an empty string. Maybe someone else better versed in Wordpress  
SQL usage can see the problem.

This is NOT the official futureposts plug-in code so please don't  
distribute it as such. When there is a working fix it should be  
submitted to the original author so he can incorporate it.
