Advanced Custom Fields (ACF) is one of the most powerful WordPress plugins for custom content. The repeater field is especially useful when you want to store and loop through sets of structured data. Here’s how to get started with it.

Working with Repeater Fields Using ACF

Imagine a repeater field called "my_repeater_field" with subfields like "sub_field_1" and "sub_field_2". Here's how to fetch them:

Step 1: Check for Repeater Rows

Use the have_rows() function to confirm there’s data to work with:

<?php
if (have_rows('my_repeater_field')) {
    while (have_rows('my_repeater_field')) {
        the_row();
        $val1 = get_sub_field('sub_field_1');
        $val2 = get_sub_field('sub_field_2');

        echo 'Subfield 1: ' . $val1 . '<br>';
        echo 'Subfield 2: ' . $val2 . '<br>';
    }
}
?>

Step 2: Access Subfield Data

Once inside the loop, use get_sub_field() to extract individual field values. This method allows for displaying each entry as needed.

Why Use Repeater Fields?

ACF repeaters simplify the creation of flexible data structures such as sliders, accordions, and grouped content without cluttering your admin panel. The have_rows() and get_sub_field() combo makes front-end rendering effortless.
