To make it clearer this

<?php if( $qualite ): ?>
	<?php foreach( $posts as $post ): 
					
	echo '<dd class="filtr" data-filter=".'.  $post->ID .'">'. get_the_title( $post->ID ) .'</dd>';
	?><?php endforeach; ?>
	<?php endif; ?

is giving me multiple copies of the same. How can i strip the duplicates out? I have been looking at array_unique and DISTINCT but I can’t figure out how to implement this here.
I have currently implemented some jquery that removes the duplicates but i am not exactly happy about that solution. Any pointers. Thanks
