Explanation

Want to tidy up your WordPress posts by hiding those pesky meta elements? Here's a simple way to do it!

Removing Meta Data from Posts:

This code uses a filter to remove meta data from your post content. It looks for any HTML elements with the class post-meta and strips them out. This means any meta information wrapped in a <div class="post-meta"> tag will be hidden from view on the front end.

Hiding Meta Boxes in the Admin Area:

If you want to clean up the post editing screen in the admin area, this code also removes certain meta boxes. It hides the Custom Fields, Comments Status, Comments, and Author boxes, making the editing interface less cluttered.

By adding these functions to your theme's functions.php file, you can easily manage what meta information is visible both on your site and in the admin area. Just remember, this doesn't delete the data; it simply hides it from view.

Code
<?php
// Function to remove post meta data from WordPress posts
function wp_dudecom_remove_post_meta() {
    // Remove meta data from the post content
    add_filter('the_content', 'wp_dudecom_filter_post_meta', 20);
}

// Callback function to filter out meta data
function wp_dudecom_filter_post_meta($content) {
    // Use regular expressions to remove meta data
    $content = preg_replace('/<div class="post-meta">.*?<\/div>/s', '', $content);
    return $content;
}

// Hook the function to WordPress
add_action('init', 'wp_dudecom_remove_post_meta');

// Function to hide custom meta boxes in the WordPress admin
function wp_dudecom_hide_custom_meta_boxes() {
    // Remove specific meta boxes from the post editing screen
    remove_meta_box('postcustom', 'post', 'normal'); // Custom Fields
    remove_meta_box('commentstatusdiv', 'post', 'normal'); // Comments Status
    remove_meta_box('commentsdiv', 'post', 'normal'); // Comments
    remove_meta_box('authordiv', 'post', 'normal'); // Author
}

// Hook the function to the admin menu
add_action('admin_menu', 'wp_dudecom_hide_custom_meta_boxes');
?>
