WordPress: get post_parent title

I've created a custom sidebar that grabs the p开发者_开发知识库ost parent's pages:

query_posts("post_type=page&post_parent=6"); 

I'd like to grab the title of the post_parent (i.e. "About"). the_title won't work because it's the title of the child pages.

How can I output the post_parent title?

---

echo get_the_title( $post->post_parent );

or

echo get_the_title( X );

Where X is any valid post/page ID.

No need to get a complete post object just for one property.

It looks like you've already got the ID of the parent post, so you can just use this:

<?php
    $parent_post_id = 6;
    $parent_post = get_post($parent_post_id);
    $parent_post_title = $parent_post->post_title;
    echo $parent_post_title;
?>

(Insert your parent post id at $parent_post_id)

This is the clean and nice code you need:

It is also save to use when there is more than one parent hierarchy level.

<?php 

    $current = $post->ID;

    $parent = $post->post_parent;

    $grandparent_get = get_post($parent);

    $grandparent = $grandparent_get->post_parent;

    ?>

    <?php if ($root_parent = get_the_title($grandparent) !== $root_parent = get_the_title($current)) {echo get_the_title($grandparent); }else {echo get_the_title($parent); }?>

---

I know it's super old question, but in case anyone was looking for some nice one-liner. Here it is:

echo get_the_title( wp_get_post_parent_id( get_the_ID() ) );

If you want to keep title filter go with:

echo apply_filters( 'the_title', get_the_title( wp_get_post_parent_id( get_the_ID() ) ) );

WordPress 5.7 introduces a new helper function to more easily fetch the parent post's ID: get_parent_post()

This can also be used in conjunction with has_parent_post(), so you could have something like looks like:

<?php if ( has_parent_post() ) : ?>
    <a href="<?php the_permalink( get_parent_post() ); ?>">
        <?php the_title( get_parent_post() ); ?>
    </a>
<?php endif; ?>

Note that these functions accept a "child post ID" as a parameter, which defaults to the current post.

I wrote this, it will grab the parent post and then echo the parents title and such. Have a look and let me know if it works for you.

This should even work outside of the wordpress loop as well.
