Prevent Post Duplication - wordpress

Question

I am in charge of managing this site F9 Properties which is built in WordPress. On the home page there is a featured properties section. I noticed that if you listed a property with two different "Status" such as "For Sale or For Lease, the property appeared twice in the carousel. Below is the code for listing the featured properties. I can see that it filters out the properties with the Status "Leased". Can anyone help me add a bit of code to list only one property per post regardless of how many different property status it has?
<?php
/* Featured Properties Query Arguments */
$featured_properties_args = array(
'post_type' => 'property',
'posts_per_page' => 100,
'meta_query' => array(
array(
'key' => 'REAL_HOMES_featured',
'value' => 1,
'compare' => '=',
'type' => 'NUMERIC'
)
)
);
$featured_properties_query = new WP_Query( $featured_properties_args );
if ( $featured_properties_query->have_posts() ) :
?>
<section class="featured-properties-carousel clearfix">
<?php
$featured_prop_title = get_option('theme_featured_prop_title');
$featured_prop_text = get_option('theme_featured_prop_text');
if(!empty($featured_prop_title)){
?>
<div class="narrative">
<h3><?php echo $featured_prop_title; ?></h3>
<?php
if(!empty($featured_prop_text)){
?><p><?php echo $featured_prop_text; ?></p><?php
}
?>
</div>
<?php
}
?>
<div class="carousel es-carousel-wrapper">
<div class="es-carousel">
<ul class="clearfix">
<?php
while ( $featured_properties_query->have_posts() ) :
$featured_properties_query->the_post();
?>
<?php
$status_terms = get_the_terms( $post->ID,"property-status" );
if(!empty( $status_terms )){
foreach( $status_terms as $status_term ){
if($status_term->name=="Leased"){}else{
?>
<li>
<figure>
<a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>">
<?php
the_post_thumbnail('property-thumb-image',array(
'alt' => get_the_title($post->ID),
'title' => get_the_title($post->ID)
));
?>
</a>
</figure>
<h4><?php the_title(); ?></h4>
<p><?php framework_excerpt(8); ?> <?php _e('Know More','framework'); ?> </p>
<span class="price"><?php property_price(); ?></span>
</li>
<?
}
}
}
?>
<?php
endwhile;
wp_reset_query();
?>
</ul>
</div>
</div>

Answer 1

I might be misunderstanding your setup, but I wonder why you're looping over the terms.
I think you should instead consider excluding the leased term within the WP_Query() part (hopefully you can share it).
Then your carousel would be simplified to:
<div class="carousel es-carousel-wrapper">
<div class="es-carousel">
<ul class="clearfix">
<?php while ( $featured_properties_query->have_posts() ) : $featured_properties_query->the_post(); ?>
<li><!-- YOUR POST ITEM HERE --></li>
<?php endwhile; ?>
</ul>
</div>
</div>

You can add the post ID to an array every time an iteration occurs, and check the array if the post has already been rendered:
$shown = array(); // new array
while ( $featured_properties_query->have_posts() ) :
$featured_properties_query->the_post();
$status_terms = get_the_terms( $post->ID, 'property-status' );
if( ! empty( $status_terms ) ){
foreach( $status_terms as $status_term ){
if( $status_term->name == "Leased" || in_array( $post->ID, $shown ){
continue; // post has term "Leased" or already rendered, skip
}
$shown[] = $post->ID; // add post ID to array
?>
<!-- HTML here -->
<?php
}
}
endwhile;
