Trying to add conditional tabs to my product pages and have managed to get a text field to show but having issue getting the repeater field to display.

Conditional tab: get_field / working

/* Create Technical details tab */
add_filter( 'woocommerce_product_tabs', 'specs_tab' );
function specs_tab( $tabs ) {
  // ensure ACF is available
  if ( !function_exists( 'get_field' ) )
    return;
  $content = trim( get_field( 'technical_details' ) );
  if ( !empty( $content ) ) {
    $tabs[] = array(
      'title' => 'Technical specifications',
      'priority' => 15,
      'callback' => 'show_tech_content'
    );
  }
  return $tabs;
}

function show_tech_content() {
  echo get_field( 'technical_details' );
}

Conditional tab: have_rows / Not working

add_filter( 'woocommerce_product_tabs', 'downloads_tab' );
function downloads_tab( $tabs ) {
  // ensure ACF is available
  if ( !function_exists( 'have_rows' ) )
    return;
  $content = trim( the_sub_field( 'name_pdf' ) );
  if ( !empty( $content ) ) {
    $tabs[] = array(
      'title' => 'Downloads',
      'priority' => 15,
      'callback' => 'show_download_content'
    );
  }
  return $tabs;
}

function show_download_content() {
if( have_rows('downloads') ):
 	// loop through the rows of data
    while ( have_rows('downloads') ) : the_row();
        // display a sub field value
        echo '<p>'.the_sub_field('name_pdf').'<.p>';
    endwhile;
endif;
}

Hi @renee

Could you try this instead. I think it’s possible you could still use have_rows etc. for the looping of the repeater this just feels safer. Also I think your main issue was that you were looking if the_sub_field(‘product_pdf’) existed without first being in a loop (and the_* will always try to echo the results which is not desired when fetching a value for a variable).

<?php
add_filter( 'woocommerce_product_tabs', 'downloads_tab' );
function downloads_tab( $tabs ) {
  // ensure ACF is available
  if ( !function_exists( 'have_rows' ) )
    return;
    
  if ( get_field('downloads') ) {
    $tabs[] = array(
      'title' => 'Downloads',
      'priority' => 15,
      'callback' => 'show_download_content'
    );
  }
  return $tabs;
}

function show_download_content() {
	$downloads = get_field('downloads');
	if( $downloads ):
	 	// loop through the rows of data
	    foreach ( $downloads as $download ) :
	        // display a sub field value
	        echo '<p>'. $download['name_pdf'].'<.p>';
	    endwhile;
	endif;
}
