Secure Custom Field after excerpt [additional]

Hey Ismael

Excellent thanks and I’ve combined the two functions for simplicity and posting here if anyone else wants a function that adds custom fields to grid posts (ALB) and single posts (Non-ALB).

// Helper function to generate the custom event details HTML
function generate_custom_event_details($post_id) {
    $event_date = get_post_meta($post_id, 'event_date', true);
    $event_time = get_post_meta($post_id, 'event_time', true);
    $event_location = get_post_meta($post_id, 'event_location', true);

    $custom_output = '<div class="custom-event-details">';
    if ($event_date) {
        $custom_output .= '<p class="event-date"><strong>Event Date:</strong> ' . esc_html($event_date) . '</p>';
    }
    if ($event_time) {
        $custom_output .= '<p class="event-time"><strong>Event Time:</strong> ' . esc_html($event_time) . '</p>';
    }
    if ($event_location) {
        $custom_output .= '<p class="event-location"><strong>Event Location:</strong> ' . esc_html($event_location) . '</p>';
    }
    $custom_output .= '</div>';

    return $custom_output;
}

// Filter for avf_post_slider_entry_excerpt
add_filter('avf_post_slider_entry_excerpt', function ($excerpt, $prepare_excerpt, $permalink, $entry, $context) {
    $custom_output = generate_custom_event_details($entry->ID);

    // Check if the "Read More" link exists in the excerpt
    $read_more_position = strpos($excerpt, '<a');
    if ($read_more_position !== false) {
        // Insert the custom output before the "Read More" link
        $before_read_more = substr($excerpt, 0, $read_more_position);
        $read_more_and_after = substr($excerpt, $read_more_position);
        return $before_read_more . $custom_output . $read_more_and_after;
    }

    // Append custom output if no "Read More" link is found
    return $excerpt . $custom_output;
}, 10, 5);

// Filter for the_content
add_filter('the_content', function ($content) {
    if (is_singular('post')) {
        $custom_output = generate_custom_event_details(get_the_ID());
        $content .= $custom_output;
    }

    return $content;
}, 10);
