excluding post from certain category

Hello Pauro. Here is dirty fix for this categoy excluding from Time Machine.

Find line 250 in time-machine.php and replace this code:

foreach ( $r as $post )
{
	// prepare excerpt
	if ( $tm_excerpt == TRUE ) {
		$tm_post_excerpt   = $post->post_excerpt;
		if ( $tm_excerpt_cut == TRUE ) {
			if ( $tm_excerpt_length && mb_strlen($tm_post_excerpt) > ($tm_excerpt_length+1) ) { $tm_post_excerpt = tm_substr_utf8($tm_post_excerpt, 0, $tm_excerpt_length)."…"; }
		}
	}

	// print formated post line
	if ( $options['display_commentnum'] == "1" ) { $pcount = ' (<span title="'.__("Number of comments", "tm").'">'.$post->comment_count.'</span>)'; } else { $pcount = ""; }
	echo '<li>'.substr($post->post_date,0,4).': <a href="'.get_permalink($post->ID).'" title="'.__("Published at", "tm").' '.$post->post_date.'">'.$post->post_title.'</a>'.$pcount.' '.$tm_excerpt_before.$tm_post_excerpt.$tm_excerpt_after.'</li>';
}

with this code:

foreach ( $r as $post )
{
	$pcats = get_the_category($post->ID);
	$no_this = 0;
	foreach ($pcats as $pcat) {
		if ( preg_match("/(5|2)/", $pcat->cat_ID) ) { $no_this = 1; }
	}
	if ($no_this <> 1) {

		// prepare excerpt
		if ( $tm_excerpt == TRUE ) {
			$tm_post_excerpt   = $post->post_excerpt;
			if ( $tm_excerpt_cut == TRUE ) {
				if ( $tm_excerpt_length && mb_strlen($tm_post_excerpt) > ($tm_excerpt_length+1) ) { $tm_post_excerpt = tm_substr_utf8($tm_post_excerpt, 0, $tm_excerpt_length)."&hellip;"; }
			}
		}

		// print formated post line
		if ( $options['display_commentnum'] == "1" ) { $pcount = ' (<span title="'.__("Number of comments", "tm").'">'.$post->comment_count.'</span>)'; } else { $pcount = ""; }
		echo '<li>'.substr($post->post_date,0,4).': <a href="'.get_permalink($post->ID).'" title="'.__("Published at", "tm").' '.$post->post_date.'">'.$post->post_title.'</a>'.$pcount.' '.$tm_excerpt_before.$tm_post_excerpt.$tm_excerpt_after.'</li>';

	} //no_this
}

And also replace in line if ( preg_match("/(5|2)/", $pcat->cat_ID) ) { $no_this = 1; } numbers 5|2 with category ID’s you wish to exclude, separated with pipe sign |.

Nicely done,perfect solution, thank you so much.

Hello great plugin. I want to show just one Category and to exlcude: 5,2,28,57,10,8,20,2,4,29,3,56

How this must to look?

if ( preg_match(“/(5|2|28|57|10|8|20|2|4|29|3|56)/”, $pcat->cat_ID) ) { $no_this = 1; }

is not working

Thanks

I want to use that plugin for a “On this day is happen:”. This data will be take from category with ID=58. I want to exclude all other categories. When I write all my categires instead of 58 … it is no work, when I take from the list just one of the category it is work but I want to show only CAT=58… and none from others. Can you help?

Huh, w/o digging code again, instead of using if( preg_match… ) use exact match

if ( $pcat->cat_ID != 58 ) { $no_this = 1; }

Does this dirty hack works as U expected?

Work perfect. Thanks!

urkekg, just one simple question. What can be the reasson the changes of the plugin to show years ago events from can 58 to be change not in 00:00 my time, because in 1:30 AM they are stil from previos date. On the morning, about 7:00 AM they are with correct date. I assume is somthing with the time zone. My wordpress clock is correctly setup as our time in Bulgaria +3:00 GMT.

Thanks
