好的,我漫长的一天正赶上我......我正在尝试列出自定义的帖子元字段并不断收到通知:未定义的索引:相关标题... 这是数组的样子:
$entries = get_post_meta( get_the_ID(), 'ss-related-posts' );
// print_r($entries);
foreach ( (array) $entries as $key => $entry ) {
$title = '';
$title = $entry['related-headline'];
echo $title;
}
这是我的代码:
{{1}}
我知道我在这里遗漏了一些简单的东西,所以任何帮助都会非常感激。

我按照comments by cale_b中的建议,只需将TRUE
添加到函数调用中即可实现:
$entries = get_post_meta( get_the_ID(), 'ss-related-posts', TRUE );
foreach ( (array) $entries as $key => $entry ) {
$title = $url = $img = "";
$title = $entry['related-headline'];
$url = $entry['related-url'];
$img = $entry['related-image'];
echo $title . "<br>" . $url . "<br>" . $img . "<br>";
}
