Advanced Custom Fields (ACF) for Dynamic WordPress Sites

Introduction

When I first started building WordPress websites, most projects were relatively straightforward. A homepage, service pages, a contact form, and perhaps a blog section. The default WordPress editor was usually enough to manage content.

However, as client requirements became more advanced, I realized that modern websites need far more than standard posts and pages. Businesses want team directories, service listings, testimonials, project portfolios, FAQs, image galleries, social media management, and dynamic landing pages.

Trying to manage all this information inside the default editor quickly becomes difficult and unorganized.

This is where Advanced Custom Fields (ACF) completely transforms WordPress development.

Advanced Custom Fields (ACF) allows developers to create structured content fields that are easy for clients to manage while giving developers complete control over how content is displayed on the frontend.

In this article, we’ll explore how Advanced Custom Fields (ACF) helps build dynamic and scalable websites, review commonly used field types, discuss Repeater Fields, Gallery Fields, Theme Options Pages, and examine practical code examples used in real-world WordPress projects.

What is Advanced Custom Fields (ACF)?

Advanced Custom Fields (ACF) is one of the most popular WordPress plugins for creating custom content structures.

Instead of storing everything inside the content editor, developers can create dedicated fields for specific types of information.

For example:

Team Member

Name
Designation
Email
Profile Image
LinkedIn URL

Service

Service Name
Service Icon
Price
Duration
Description

Project

Project Name
Gallery
Client Name
Completion Date
Project URL

By using Advanced Custom Fields (ACF), content remains organized, consistent, and easy to manage.

Why I Use Advanced Custom Fields (ACF) on Almost Every Project

One of the biggest challenges in WordPress development is creating websites that clients can manage without technical knowledge.

Without Advanced Custom Fields (ACF):

Content becomes inconsistent
Editors accidentally break layouts
Updating information becomes difficult

With Advanced Custom Fields (ACF):

Content remains structured
Layouts stay consistent
Editors have a better experience
Development becomes more scalable

For this reason, Advanced Custom Fields (ACF) has become a standard part of my WordPress development workflow.

Understanding ACF Field Groups

Before creating fields, ACF requires a Field Group.

A Field Group is simply a collection of related fields.

Example:

Team Member Field Group

Name
Designation
Email
Phone Number
Profile Image
LinkedIn URL

This ensures all team-related information remains grouped together.

Text Field

The Text Field is one of the most commonly used field types in Advanced Custom Fields (ACF).

Typical uses include:

Names
Job Titles
Service Names
Company Names

Example

<?php

$title = get_field('service_title');

echo $title;

?>

Direct Output

<?php the_field('service_title'); ?>

Output:

Custom WordPress Development

Textarea Field

Textarea fields are ideal for longer descriptions.

Common uses:

Testimonials
Service Summaries
Team Bios

Example

<?php

$description = get_field('service_description');

echo $description;

?>

Output:

We provide custom WordPress development solutions for businesses.

WYSIWYG Editor Field

The WYSIWYG field provides a full content editor experience.

Ideal for:

Service Details
About Pages
Landing Page Content

Example

<?php

$content = get_field('service_content');

echo $content;

?>

This allows content editors to manage rich text content without touching code.

Number Field

Useful for:

Pricing
Years of Experience
Project Counts

Example

<?php

$price = get_field('service_price');

echo '$' . $price;

?>

Output:

$999

Email Field

The Email Field ensures proper email formatting.

Example

<?php

$email = get_field('contact_email');

?>

<a href="mailto:<?php echo esc_attr($email); ?>">
    <?php echo esc_html($email); ?>
</a>

URL Field

Perfect for:

Website Links
Social Media Profiles
Portfolio URLs

Image Field

The Image Field is one of the most frequently used features of Advanced Custom Fields (ACF).

Common uses:

Team Images

Banners
Client Logos

Return Format: Array

<?php

$image = get_field('team_image');

?>

<img
    src="<?php echo esc_url($image['url']); ?>"

>

Return Format: ID

<?php

$image_id = get_field('team_image');

echo wp_get_attachment_image(
    $image_id,
    'full'
);

?>

File Field

Useful for:

PDF Downloads
Brochures
Reports

Example

$file = get_field('brochure');

$status = get_field('project_status');

echo $status;

?>

Checkbox Field

Useful when multiple values can be selected.

Example

$skills = get_field('skills');

if($skills):

    foreach($skills as $skill):

        echo '<li>' . $skill . '</li>';

    endforeach;

endif;

?>

Output:

WordPress
PHP
JavaScript

Radio Button Field

Useful when only one option can be selected.

Example

$package = get_field('package_type');

echo $package;

?>

Output:

Date Picker Field

Relationship Field

One of the most powerful features in Advanced Custom Fields (ACF).

if($services):

foreach($services as $service):

?>

<h3>
    <?php echo get_the_title($service); ?>
</h3>

<?php

endforeach;

endif;

?>

Repeater Field Explained

The Repeater Field is one of the most valuable features in Advanced Custom Fields (ACF) Pro.

It allows users to add unlimited rows of content.

Common uses:

FAQs
Testimonials
Team Members
Pricing Tables

FAQ Example

Fields:

Question
Answer

Code:

<?php

if( have_rows('faqs') ):

while( have_rows('faqs') ):

the_row();

?>

<h3>

<?php the_sub_field('question'); ?>

</h3>

<p>

<?php the_sub_field('answer'); ?>

</p>

<?php

endwhile;

endif;

?>

Team Repeater Example

Fields:

Name
Designation
Image

Code:

<?php

if( have_rows('team_members') ):

while( have_rows('team_members') ):

the_row();

$image = get_sub_field('image');

?>

<img src="<?php echo $image['url']; ?>">

<h3>

<?php the_sub_field('name'); ?>

</h3>

<p>

<?php the_sub_field('designation'); ?>

</p>

<?php

endwhile;

endif;

?>

Gallery Field Explained

The Gallery Field allows multiple images to be managed from one location.

Perfect for:

Portfolio Websites
Construction Projects
Product Showcases

Gallery Grid Example

<?php

$images = get_field('project_gallery');

if($images):

?>

<div class="gallery-grid">

<?php foreach($images as $image): ?>

    <img
        src="<?php echo esc_url($image['sizes']['medium']); ?>"
        alt="<?php echo esc_attr($image['alt']); ?>"
    >

<?php endforeach; ?>

</div>

<?php endif; ?>

CSS:

.gallery-grid{
    display:grid;
    grid-template-columns:repeat(3,1fr);
    gap:20px;
}

Gallery Slider Example

Many developers combine Advanced Custom Fields (ACF) with Swiper.js.

<?php

$images = get_field('project_gallery');

?>

<div class="swiper">

<div class="swiper-wrapper">

<?php foreach($images as $image): ?>

<div class="swiper-slide">

<img
src="<?php echo $image['url']; ?>"
alt="<?php echo $image['alt']; ?>"
>

</div>

<?php endforeach; ?>

</div>

</div>

This creates a fully dynamic image slider.

Flexible Content Field

The Flexible Content Field works like a custom page builder.

Possible layouts:

Hero Section
Content Section
FAQ Section
Gallery Section
CTA Section

Example

<?php

if( have_rows('page_builder') ):

while( have_rows('page_builder') ):

the_row();

if( get_row_layout() == 'hero_section' ):

get_template_part(
'template-parts/hero'
);

elseif( get_row_layout() == 'faq_section' ):

get_template_part(
'template-parts/faq'
);

endif;

endwhile;

endif;

?>

Creating a Theme Settings Page

One of my favorite uses of Advanced Custom Fields (ACF) is creating a Theme Settings page.

Examples:

Phone Number
Email Address
Social Media Links
Footer Copyright

Create Admin Menu

if(function_exists('acf_add_options_page')){

    acf_add_options_page(array(

        'page_title' => 'Theme Settings',

        'menu_title' => 'Theme Settings',

        'menu_slug'  => 'theme-settings',

        'capability' => 'edit_posts',

        'redirect'   => false

    ));

}

Managing Social Media Links

Fields:

facebook_url
instagram_url
linkedin_url
youtube_url

Display Example

<?php

$facebook = get_field(
'facebook_url',
'option'
);

?>

<a href="<?php echo esc_url($facebook); ?>">

Facebook

</a>

Displaying Header Contact Information

Fields:

phone_number
email_address

Code:

<?php

echo get_field(
'phone_number',
'option'
);

echo get_field(
'email_address',
'option'
);

?>

Now the client can update contact information from one central location.
