Benefits of Custom Field Groups

- Dynamic Content: Use custom fields to display dynamic data on your site.
- Simplified Admin Interface: Provide intuitive options for non-technical users to manage content.

Getting Started with ACF
Installing ACF
Before creating your first custom field group, ensure ACF is installed and activated on your WordPress site.
- Go to your WordPress dashboard.
- Navigate to Plugins > Add New.
- Search for “Advanced Custom Fields” and click Install Now.
- Once installed, click Activate.
You’re now ready to create your first custom field group!
Step-by-Step Guide to Creating a Custom Field Group
Step 1: Access the ACF Interface
- From your WordPress dashboard, navigate to Custom Fields in the left-hand menu.
- Click Add New to create a new field group.
This will take you to the field group editor, where you can configure your custom fields.
Step 2: Name Your Field Group
Give your field group a descriptive name that reflects its purpose. For example, if you’re creating fields for a portfolio project, name it “Portfolio Fields.”
Step 3: Add Custom Fields
Click the Add Field button to create a new field.
Field Options
- Field Label: Enter a descriptive label, such as “Project Title” or “Completion Date.”
- Field Name: This is auto-generated based on the label but can be edited if needed.
- Field Type: Select the type of input, such as text, image, or date picker.
Example Fields for a Portfolio Project:
- Project Title (Text Field)
- Client Name (Text Field)
- Completion Date (Date Picker)
- Project Description (Text Area)
Step 4: Configure Field Settings
For each field, configure additional settings to ensure it behaves as desired.
Key Field Settings
- Required: Make the field mandatory for content entry.
- Default Value: Set a pre-filled value to save time for users.
- Conditional Logic: Show or hide fields based on specific criteria.
Example: Use conditional logic to display a “Project Budget” field only if a “High-Priority” checkbox is selected.
Assigning the Field Group
Step 5: Set Location Rules
In the Location Rules section, define where this field group should appear. For example:
- Assign to Post Type > Portfolio to show fields on portfolio posts.
- Assign to Page > Home to display fields on the homepage editor.
Step 6: Publish the Field Group
Once you’ve added all fields and configured the settings, click the Publish button. Your field group is now active and ready for use.
Displaying Custom Fields on Your Site
Using PHP in Templates
To display custom field data on your site, use ACF functions like get_field() or the_field() in your theme templates.
Example Code
<?php
$project_title = get_field('project_title');
$completion_date = get_field('completion_date');
if ($project_title) {
echo '<h2>' . esc_html($project_title) . '</h2>';
}
if ($completion_date) {
echo '<p>Completion Date: ' . esc_html($completion_date) . '</p>';
}
?>
Add this code to your theme file (e.g., single-portfolio.php) to display custom fields dynamically.
Using Page Builders
If you’re using a page builder like Elementor, you can display custom fields without coding.
- Edit the page or post with Elementor.
- Add a widget, such as Text or Heading.
- Use the Dynamic Tags option to select your custom field.
For more details, visit the Elementor dynamic content guide.
Advanced Techniques for Custom Fields
Repeater Fields
Repeater fields allow you to add multiple rows of data, such as lists of team members or product specifications.
Example Code for Repeater Fields
<?php
if (have_rows('team_members')) {
echo '<ul>';
while (have_rows('team_members')) {
the_row();
echo '<li>' . esc_html(get_sub_field('name')) . ' - ' . esc_html(get_sub_field('role')) . '</li>';
}
echo '</ul>';
}
?>
Conditional Logic
Conditional logic ensures only relevant fields appear in the admin interface.
Example Use Case: Display a “Sale Price” field only if the “On Sale” checkbox is selected.
Testing and Debugging
Enable Debugging
Debugging ensures your custom fields function correctly.
Steps to Enable Debug Mode
- Edit your
wp-config.phpfile. - Add the following lines:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
- Review the debug log in the
wp-content/debug.logfile for issues.
Use Query Monitor
The Query Monitor plugin helps identify performance issues related to custom fields.
Real-World Applications
Portfolio Websites
Add fields like client names, project descriptions, and tools used for portfolio projects.
E-Commerce Stores
