After adding layouts to the Flexible Content Field, you can configure a few additional settings related to how it appears when viewed in the Admin area.

  • Minimum Layouts: Sets a limit on how many layouts are required.

 Template usage   

The ACF Flexible Content field returns a multi-dimensional array containing the layouts and their sub-field values.

Accessing the value is done via the have_rows, the_row, get_sub_field, and the_sub_field functions.

 Loop example   

This example demonstrates how to loop over an ACF Flexible Content field value and access subfields from different layouts.

<?php

// Check value exists.
if( have_rows('content') ):

    // Loop through rows.
    while ( have_rows('content') ) : the_row();

        // Case: Paragraph layout.
        if( get_row_layout() == 'paragraph' ):
            $text = get_sub_field('text');
            // Do something...

        // Case: Download layout.
        elseif( get_row_layout() == 'download' ): 
            $file = get_sub_field('file');
            // Do something...

        endif;

    // End loop.
    endwhile;

// No value.
else :
    // Do something...
endif;

 Display layouts   

This example demonstrates how to loop through a Flexible Content field and generate HTML for different layouts.

<?php if( have_rows('content') ): ?>
    <?php while( have_rows('content') ): the_row(); ?>
        <?php if( get_row_layout() == 'paragraph' ): ?>
            <?php the_sub_field('paragraph'); ?>
        <?php elseif( get_row_layout() == 'image' ): 
            $image = get_sub_field('image');
            ?>
            <figure>
                <?php echo wp_get_attachment_image( $image['ID'], 'full' ); ?>
                <figcaption><?php echo $image['caption']; ?></figcaption>
            </figure>
        <?php endif; ?>
    <?php endwhile; ?>
<?php endif; ?>
