filter by year

Hi @matdeweb

Perhaps the best solution here would be creating a custom field that pulls only the post-year data and saves it as a value. This way, you can create a filter based on it in the form of a simple list of years.

HI @matdeweb

That would require a custom code which will be fired on the post save/update.
Something like this (please note that this is not a tested code/solution this is just an example):

<?php
add_action('save_post', 'update_post_year_custom_field', 10, 3);

function update_post_year_custom_field($post_id, $post, $update) {
    // Prevent autosave from triggering the update
    if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
        return;
    }

    // Check if this is a revision or an unsupported post type
    if (wp_is_post_revision($post_id) || !in_array($post->post_type, ['post'])) {
        return;
    }

    // Verify user permissions
    if (!current_user_can('edit_post', $post_id)) {
        return;
    }

    // Get the post's publish date
    $post_date = get_the_date('Y-m-d', $post_id);
    if ($post_date) {
        // Extract the year
        $year = date('Y', strtotime($post_date));
        // Update the custom field 'post_year' with the year
        update_post_meta($post_id, 'post_year', $year);
    }
}
?>

Best regards
