Clients want to change banners, phone numbers and service lists themselves — but free-form editing breaks layouts easily. ACF (Advanced Custom Fields) solves exactly that: I design the inputs, clients just fill them in.

The idea

1. Create a field group with the inputs you need.
2. Assign it to the right page or content type.
3. Read the values in the template and output them in the design.

Field types I use most

*Repeater and Options pages are ACF PRO features.

Rendering in the theme

<?php $hero = get_field( 'hero' ); ?>
<section class="hero">
  <h1><?php echo esc_html( $hero['title'] ); ?></h1>
  <?php if ( $hero['image'] ) : ?>
    <?php echo wp_get_attachment_image( $hero['image']['ID'], 'large' ); ?>
  <?php endif; ?>
</section>

<?php while ( have_rows( 'services' ) ) : the_row(); ?>
  <h3><?php echo esc_html( get_sub_field( 'name' ) ); ?></h3>
<?php endwhile; ?>

Tips

• Always escape output (esc_html, esc_url, esc_attr).
• Use wp_get_attachment_image() for automatic srcset, dimensions and lazy loading.
• Enable Local JSON (an acf-json folder in the theme) so field settings live in Git and sync between local and server.
• Clear labels and short instructions for clients.
• Set limits — title length, minimum image size, maximum rows — to keep the design intact.
