Selecting a Repeater Field in ACF Based on Product Size in WordPress

WordPress is one of the most popular content management systems due to its high adaptability and support from various plugins, allowing developers to easily add more advanced capabilities to websites. One of these plugins is "Advanced Custom Fields" or ACF, which enables the creation of custom fields for each post type in WordPress.

In ACF, Repeater Fields give you the ability to add multiple sets of information to a single post. For example, you can add multiple details such as size, colors, and so on for each product. Here, I will show how you can select a specific row from this Repeater based on product size.

Suppose you want to filter product details based on a specific size. This can be done using PHP functions and snippets that I'll be explaining further in the code and descriptions.

To implement this capability and select a specific Repeater row based on product size, you must first put ACF in a suitable format in the WordPress template. Then, by utilizing the functions and specific snippets, we aim to reach our goals.

// Suppose the size of interest is "Large"
if( have_rows('product_details') ): // Check if this field has rows or not
  while ( have_rows('product_details') ) : the_row(); // Start the loop to display each row
    $size = get_sub_field('size'); // Get the size value
    if( $size == 'Large' ) : // Check this condition for the size
      the_sub_field('product_name'); // Display the product name for the specific size
    endif;
  endwhile;
endif;
