check if posts are in custom taxonomy

[kokosan]

Hi, I almost finish. Could you tell me abit about this? I want to show div in the result if posts are in custom taxonomy “topic1” (for example). I have different design to show based on custom taxonomy. In the result template, I don’t kow how to check if posts are in taxonomy “topic1”.

<?php 
$key = count_val';
if ($r->content_type == 'pagepost' ) {
$meta_value = get_post_meta( $r->id, $key, true );
?>
<div> //show this div on the result if posts are in taxonomy "topic1"
<span><?php echo $meta_value;?></span>
</div>
<?php
}
?>

Hi,

I am not exactly sure where this code is placed, so it highly depends. But you are using get_post_meta, which is for custom fields and not taxonomies. If you are checking for taxonomies, then maybe use the get_terms function or similar.

Hi, sorry for not being clear. The code below displays the div on every post. I want to display the div below only if a post has custom taxonomy “topic1”. In this case, use $r->content_type == 'pagepost' or 'term'?

<?php
if ($r->content_type == ‘pagepost’ ) {
?>
<div>show this div on the result if posts are in taxonomy “topic1″</div>
<?php
}
?>

But the problem is, that posts can’t have taxonomies – posts can only have terms from custom taxonomies associated to them.
Taxonomies are the “group” for terms, for example categories are part of a taxonomy called “categories” etc..

If you want to check if the post is in a specific category, then use the has_term() function. With this you can check if a post is within a specific category or any other taxonomy term.

I can get it done now, somehting like this

add_filter( 'asp_results', 'asp_show_element_taxonomy', 10, 1 );
function asp_show_element_taxonomy( $results ) {
	foreach ($results as $k=>&$r) {
	    $extext = get_post_meta($r->id, 'example_text', true);
      if (has_term('', 'exampletaxonomies',$r->id))
	  	$r->content = "<span>$extext</span><span>show this div</span>";
	}
	return $results;
}

Very awesome plugin, actually no need to create a separated custom post type to achieve this like I think before.

One problem is that filter by this taxonomy is not working. I asign two posts to this taxonomy and add it to filter. When I click this filter, it show all posts, in stead of the twe posts that has this taxonomy . But, I see the two posts if use Uncategorized category filter.

For the filter, try this configuration: https://i.imgur.com/Iu8w0WB.png
That should exclude posts which have not been assigned any terms from the taxonomy.
