在Wordpress中向相关帖子添加高级自定义字段

Question

I am trying to add a custom field value to related posts functionality, but am currently totally stuck at this:

<div class="relatedposts">  
<h3>Related posts</h3>  
<?php  
$orig_post = $post;  
global $post;  
$tags = wp_get_post_tags($post->ID);  

if ($tags) {  
$tag_ids = array();  
foreach($tags as $individual_tag) $tag_ids[] = $individual_tag->term_id;  
$args=array(  
'tag__in' => $tag_ids,  
'post__not_in' => array($post->ID),  
'posts_per_page'=>4, // Number of related posts to display.  
'caller_get_posts'=>1  
);  

$my_query = new wp_query( $args );  

while( $my_query->have_posts() ) {  
$my_query->the_post();

?>  

<div class="relatedthumb">  
<a rel="external" href="<? the_permalink()?>">
<?php 
$image = wp_get_attachment_image_src(get_field('image'), 'full');
print_r( $image[0] ); ?>
<?php the_title(); ?>
<img src="<?php echo $image[0]; ?>" />
</a>  
</div>  

<? }  
}  
$post = $orig_post;  
wp_reset_query();  
?>  
</div> 

This mostly works as it is code found online, it is just where to put the reference to the custom field that I seem to be missing. I am unable to place the variable and print_r of this anywhere to see the results.

Answer 1

foreach($tags as $individual_tag) { $meta_values = get_post_meta($post->ID,'');

    if (in_array('VALUE SEARCHING FOR',$meta_values) {
        $tag_ids[] = $individual_tag->term_id;
    } // if
} // foreach

Fill in the appropriate blanks and this should filter your tags properly.
