Advanced Custom Fields是一款自定义文章字段的插件，功能较为强大，字段可以分组来指派，那么我们如何显示某个字段组下的字段呢？
也就是如何get fields from group，我们需要用到一个方法get_field_object。
<?php //or insert the ID of your fields Group. $groupID='116'; $custom_field_keys = get_post_custom_keys($groupID); foreach ( $custom_field_keys as $key => $fieldkey ) { if (stristr($fieldkey,'field_')) { //echo $key . " => " . $fieldkey . "<br />"; //echo $field['label'] . ': ' . $field['value']; //echo $fieldkey . "<br />"; $field = get_field_object($fieldkey, $groupID); $acf_field_name = $field['name']; $attachment = get_field($acf_field_name); echo "<img src='".$attachment['url']."' title='".$attachment['title']."'/>"; } } ?>以上代码参考自wordpress.stackexchange.com/questions/95126/acf-get-fields-from-group
