  $mainvisual_size = 'full';
  $mainvisual_image = wp_get_attachment_image_src( $mainvisual_attachment_id, $mainvisual_size );
  $mainvisual = $mainvisual_image[0];
  echo $mainvisual;
?>

日付

<?php
  $week = array( "日", "月", "火", "水", "木", "金", "土" );
  $date = DateTime::createFromFormat('Ymd', get_field('event-date'));
  $datetime = new DateTime($date->format('Y-m-d'));

  echo $date->format('Y'); //年
  echo $date->format('m'); //月
  echo $date->format('d'); //日
  echo $date->format('D'); //曜日
  echo $week[$datetime->format("w")]; //曜日　日本語
?>

<?php
  $relation_posts = get_field('relation');
  if($relation_posts):
?>
<ul>
  <?php foreach( $relation_posts as $post ): ?>
  <li><a href="<?php echo get_permalink( $post->ID ); ?>"><?php echo get_the_title( $post->ID ); ?></a></li>
  <?php endforeach; ?>
</ul>
<?php endif; wp_reset_postdata(); ?>

has_sub_field

<?php 
  if(get_field("content")): while(has_sub_field("content")):

          array(
               'key'     => 'color',
               'value'   => 'red',
               'compare' => 'NOT LIKE',
          ),
          array(
               'key'     => 'price',
               'value'   => array( 500, 2000 ),

指定したget_sub_fieldを一つのみ取出す

<?php
  $count = 0;
  while(the_flexible_field("content")):
    if(get_row_layout() == "text"): $count++; // layout - count
      if($count == 1):
        $first_txt = get_sub_field("text");
        $first_row_txt_html = strip_tags($first_txt); //hmtlタグを取り除く
        echo mb_substr($first_row_txt_html, 0, 100, 'UTF-8'), '…'; //文字数100文字に設定
      endif;
    endif;
  endwhile;
?>

get_row_layoutの最初にあるテキストを出力

<?php
  $rows = get_field ( 'content' );
  $first_row = $rows[0];
  $first_row_txt = $first_row['text'];
  echo $first_row['text'];
?>

チェックボックスの値を表示

$cfcb = get_field_object('field_name');
$cfcbId = get_post_meta($post->ID,'field_name');
$cfcbId = $cfcbId[0];
if($cfcb) {
  foreach($cfcbId as $v) {
    echo '<span class="ico-'. $v. '">' . $cfcb['choices'][$v] .'</span>';
  }
}

ACFのwysiwygエディタの機能を制限

add_filter('acf/fields/wysiwyg/toolbars', 'my_toolbars');
function my_toolbars( $toolbars ){

	// Uncomment to view format of $toolbars
	/*
	echo '< pre >';
		print_r($toolbars);
	echo '< /pre >';
	die;
	*/
 
	// Add a new toolbar called "Very Simple"
	// - this toolbar has only 1 row of buttons
	$toolbars['Very Simple'] = array();
	$toolbars['Very Simple'][1] = array('bold', 'italic', 'link', 'unlink');
	
	$toolbars['Very Simple (No Link)'] = array();
	$toolbars['Very Simple (No Link)'][1] = array('bold', 'italic');
 
	// Edit the "Full" toolbar and remove 'code'
	// - delet from array code from http://stackoverflow.com/questions/7225070/php-array-delete-by-value-not-key
	if( ($key = array_search('code',$toolbars['Full' ][2])) !== false){
    unset( $toolbars['Full'][2][$key]);
	}
 
	// return $toolbars - IMPORTANT!
	return $toolbars;
