Wordpress: function to replace content for custom post status - wordpress

Question

I created custom post status "blocked" via register_post_status (like this register_post_status not showing post_status in status dropdown).
Now I want to replace content on posts with this status via functions.php.
I tried something like this
function block_by_status ($post_object) {
global $wp_query;
if( 'blocked' == $wp_query->post->post_status ) {
return 'This post is blocked';
}
}
add_action('the_post','block_by_status');
But it doesn't work, please somebody help?

Answer 1

So for the content you can do something as simple as:
add_filter('the_content', 'block_by_status');
and to hide the title you can use:
add_filter( 'the_title', 'block_by_status', 10, 2 );
If you want to go further than that, I suggest editing the template in the theme folder.
For pages you need to edit page.php and for posts you need to edit posts.php or singular.php, depends on the theme you are using.
So you can do something like this:
In the functions.php file:
function block_by_status ($post_object) {
global $wp_query;
if( 'blocked' == $wp_query->post->post_status ) {
return true;
}
}
and then in the files I referenced above (Depends on your theme):
<?php if (!block_by_status()) { ?>
<?php while (have_posts()) : the_post(); ?>
<h1><?php the_title() ?></h1>
<?php the_content() ?>
<?php get_sidebar() ?>
<?php endwhile; ?>
<?php } else {
echo 'This post is blocked';
} ?>
So you use your function as a boolean and just hide what you dont want users to see.
