Wordpress - Query comments by post meta - wordpress

Question

I am using the code below (simplified) to display a list of the last 10 comments:
<?php
$args = array(
'post_type' => 'tarefa',
'number' => '10',
'order' => 'DESC',
'orderby' => 'comment_date',
//'meta_key' => 'field_name',
//'meta_value' => 'field_value',
);
$comments_query = new WP_Comment_Query;
$comments = $comments_query->query( $args );
foreach ( $comments as $comment ) {
echo '<p>';
echo get_the_title($comment->comment_post_ID) . '<br>'; //post title
echo $comment->comment_content; // comment content
echo '</p>';
};
?>
Question:
Well, meta_key and meta_value seem to be associated to comment_meta... But in my case, I have to display comments based on post_meta key and value.
Any sugestions?

Answer 1

You can try this code.
You need to add a query for posts to get array of post ides with meta key.
Then use that array into comments query argument.
//QUERY FOR POSTS WITH META KEY AND VALUE (META QUERY)
$post_args = array(
'post_type' => 'post',
'meta_key' => 'meta key',//Meta key of post
'meta_value' => 'meta value',//String or Numeric value
'meta_compare' => '=',
);
$post_query = new WP_Query( $post_args );
$posts_array= array();
if ( $post_query->have_posts() ) {
while ( $post_query->have_posts() ) {
$post_query->the_post();
$posts_array[] = get_the_ID(); //Array of post ids
}
wp_reset_postdata();
}
//YOUR COMMENT ARGS SHOULD BE THIS
$args = array(
'post_type' => 'tarefa',
'number' => '10',
'order' => 'DESC',
'orderby' => 'comment_date',
'post__in' => $posts_array, //THIS IS THE ARRAY OF POST IDS WITH META QUERY
);
Try this , then let me know the result.

My first question here at Stackoverflow and that worked perfectly.
Thank you very much, Souvik!
Below the final result (simplified):
$post_args = array(
'post_type' => 'tarefa',
'posts_per_page' => -1,
'meta_key' => 'field_name',
'meta_value' => 'field_value',
);
$post_query = new WP_Query( $post_args );
$posts_array= array();
if ( $post_query->have_posts() ) {
while ( $post_query->have_posts() ) {
$post_query->the_post();
$posts_array[] = get_the_ID(); //Array of post ids
}
wp_reset_postdata();
}
//YOUR COMMENT ARGS SHOULD BE THIS
$args = array(
'number' => '30',
'order' => 'DESC',
'orderby' => 'comment_date',
'post__in' => $posts_array, //THIS IS THE ARRAY OF POST IDS WITH META QUERY
);
$comments_query = new WP_Comment_Query;
$comments = $comments_query->query( $args );
foreach ( $comments as $comment ) {
echo '<p>';
echo get_the_title($comment->comment_post_ID) . '<br>'; //post title
echo $comment->comment_content; // comment content
echo '</p>';
};
