The aikb_render_post_meta($post_id) function is responsible for displaying the meta information for posts in your Knowledge Base (views, likes, author, date, and reading time). It is fully customizable using WordPress filters, which allows you to change visibility, labels, design, and output.

Filter: aikb_post_meta_visibility

Purpose:
Control which meta elements are displayed (views, likes, date, read time, author).

Default behavior:

$visibility = array(
    'views'  => true,
    'likes'  => true,
    'date'   => true,
    'read'   => true,
    'author' => true,
);

Usage Example:
Hide views and likes:

add_filter('aikb_post_meta_visibility', function($visibility) {
    $visibility['views'] = false;
    $visibility['likes'] = false;
    return $visibility;
});

Keys you can use:

• views – Post views count
• likes – Number of helpful votes
• date – Published or updated date
• read – Reading time
• author – Author name

Filter: aikb_post_meta_labels

Purpose:
Change the text labels for meta elements.

Default behavior:

$labels = array(
    'views'   => 'views',
    'likes'   => 'Likes',
    'post_by' => 'By',
    'read'    => 'min read'
);

Usage Example:
Rename “views” to “Seen” and “Likes” to “Helpful”:

add_filter('aikb_post_meta_labels', function($labels) {
    $labels['views'] = 'Seen';
    $labels['likes'] = 'Helpful';
    return $labels;
});

Filter: aikb_post_meta_design

Purpose:
Customize the HTML wrapper class or inline styles for the meta block.

Default behavior:

$design = array(
    'wrapper_class' => 'aikb-post-meta',
    'wrapper_style' => '',
);

Usage Example:
Add a custom class and style:

add_filter('aikb_post_meta_design', function($design) {
    $design['wrapper_class'] .= ' my-custom-class';
    $design['wrapper_style'] = 'background-color:#f5f5f5; padding:10px;';
    return $design;
});

Filter: aikb_post_meta_output

Purpose:
Modify the final HTML output of the meta block. You can append, prepend, or completely replace the output.

Default usage:

return apply_filters('aikb_post_meta_output', $html, $post_id, $views_count, $yes_count, $date_label, $display_date, $author_name);

Usage Example:
Add custom text at the end of meta:

add_filter('aikb_post_meta_output', function($html, $post_id, $views, $likes, $date_label, $date, $author) {
    $html .= '<span class="custom-meta">Thank you for reading!</span>';
    return $html;
}, 10, 7);
