Sorry, reading it back now I agree it isn’t really clear what I’m trying to accomplish 😉

I have added a two custom fields to attachments (media) using ACF.

Whenever I choose a featured image in a post, I want the custom fields for this particular attachment to show below the featured image, and save them when saving the post.

Ugh, I was in the assumption that that wouldn’t work in a walker, but I just tried a simple custom field and it works without problems.

I’ll try to fix it this way, thanks! 🙂

Hi James,

I have a flexible content field called “menu” (it’s a Restaurant menu), which has a repeater field, where each repeater field has a title. I want each title of this section as a dropdown menu for the corresponding page in the menu.

See below my export of the particular field:

I’d want the “Categorie” sub_field in my menu. I’m using a custom walker, the entire code can be seen below. It works, as long as the repeater field is the 2nd field in my flexible content.

class Cusom_Menu extends Walker_Nav_Menu {
	static $count=0;
	function start_el(&$output, $item, $depth, $args) {
		global $wp_query;
		$indent = ( $depth ) ? str_repeat( "\t", $depth ) : '';
		
		$class_names = $value = '';
		$classes = empty( $item->classes ) ? array() : (array) $item->classes;
		$class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item ) );
		$class_names = ' class="page-item-'. $item->object_id .' ' . esc_attr( $class_names ) . '"';

		if ($depth==0) self::$count=0;  // reset var when we are in first level
        if ($depth==1 && self::$count==1) {  // if we are in submenu and items count is 1...
	       $output .= '<li class="terug mobile-only"><a href="#"><i class="fa fa-lg fa-chevron-left" aria-hidden="true"></i> Terug</a></li>';
	       $parent = $item->menu_item_parent;
	       $output .= '<li class="mobile-only"><a class="hoofd-item" href="#">hoi' . $parent->ID .'</a></li></a></li>';
        }

		$output .= $indent . '<li id="menu-item-'. $item->ID . '"' . $value . $class_names .'>';
		$attributes = ! empty( $item->attr_title ) ? ' title="' . esc_attr( $item->attr_title ) .'"' : '';
		$attributes .= ! empty( $item->target ) ? ' target="' . esc_attr( $item->target ) .'"' : '';
		$attributes .= ! empty( $item->xfn ) ? ' rel="' . esc_attr( $item->xfn ) .'"' : '';
		$attributes .= ! empty( $item->url ) ? ' href="' . esc_attr( $item->url ) .'"' : '';
		$parent = wp_get_post_parent_id($item->object_id);
		$thumbnail = '';
  		if ( has_post_thumbnail( $item->object_id ) and 1 == $depth ) {
   			$thumbnail = get_the_post_thumbnail( $item->object_id );
 		}
		$item_output = $args->before;
		
		
		if (1 == $depth and $thumbnail and $parent == 43){
			$item_output .= '<a'. $attributes .' class="hoofdlink">';
			$item_output .= '<div class="afbeelding">' . $thumbnail . '</div><span>';
		} else {
			$item_output .= '<a'. $attributes .' class="link-'. $depth .'">';
		}
		$item_output .= $args->link_before . apply_filters( 'the_title', $item->title, $item->ID ) . $args->link_after;
		if (1 == $depth and $thumbnail and $parent == 43){
			$item_output .= '</span>';
		}
		$item_output .= '</a>';
		$repeater_value = get_post_meta($item->object_id, 'flexibele_content_1_menukaart-repeater', true);
		
		if (1 == $depth and $repeater_value and $parent == 43){
  			for ($i=0; $i<$repeater_value; $i++) {
    			$meta_key = 'flexibele_content_1_menukaart-repeater_'.$i.'_categorie';
    			$meta_key = 'flexibele_content_1_menukaart-repeater_'.$i.'_categorie';
    			$sub_field_value = get_post_meta($item->object_id, $meta_key, true);
    			$sub_field_link = (str_replace(' ', '-', strtolower($sub_field_value)));
		    	$item_output .= '<div><a class="sublink" href="' . esc_attr( $item->url ) .'#'. $sub_field_link .'">';
		    	$item_output .= $sub_field_value;
		    	$item_output .= '</a></div>';
 			}
		}

		$item_output .= $args->after;
		$output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
		self::$count++;
	}

	function start_lvl( &$output, $depth = 0, $args = array() ) {
        $indent = str_repeat("\t", $depth);
        $output .= "\n$indent<ul class='sub-menu'><div class='wrapper clearfix'>\n";
    }
    function end_lvl( &$output, $depth = 0, $args = array() ) {
        $indent = str_repeat("\t", $depth);
        $output .= "$indent</div></ul>\n";
    }
}

Hi James,

Thank you. I figured out it saved its data like this. The thing I’m struggling with is automatically finding the correct number. This is the code I currently have:

$repeater_value = get_post_meta($item->object_id, 'flexibele_content_1_menukaart-repeater', true);
		
		if (1 == $depth and $repeater_value){
  			for ($i=0; $i<$repeater_value; $i++) {
    			$meta_key = 'flexibele_content_1_menukaart-repeater_'.$i.'_categorie';
    			$sub_field_value = get_post_meta($item->object_id, $meta_key, true);
    			$sub_field_link = (str_replace(' ', '-', strtolower($sub_field_value)));
    	$item_output .= '<a class="sublink" href="' . esc_attr( $item->url ) .'#'. $sub_field_link .'">';
    	$item_output .= $sub_field_value;
    	$item_output .= '</a>';
 			}
		}

Actually, I found out what went wrong. I had another meta_query which overruled the one sent above.

Consider this question as solved.

Hi,

I actually solved it by making an array and then check for duplicate custom fields, like so:

 <?php
$args         = array(
    'post_type' => 'deals'
);
$the_query    = new WP_Query($args);

$unieke_deals = array();
if ($the_query->have_posts()):
    while ($the_query->have_posts()):
        $the_query->the_post();
        $bedrijf = get_field('company');
        if (!in_array($bedrijf, $unieke_deals)):
            $unieke_deals[] = $bedrijf;
?>
<?php the_field('company'); ?>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a><br />
  <?php
        endif;
    endwhile;
endif;
?>

It’s a row from the Flexible Content! 🙂
