PHP 从 WordPress 中的元键数组打印变量

发布于 2024-11-05 05:02:25 字数 768 浏览 0 评论 0原文

我正在尝试从以下数组中打印列表中的“artistName”元键：（

$postID = $post->ID;
$meta = get_post_meta($postID, $_artistMeta->$postID, TRUE);
print_r($meta);

打印以下内容）

   Array
    (
        [_artistMeta] => Array
            (
                [0] => a:1:{s:10:"artistName";a:2:{i:0;s:33:"la-semilla-de-la-cultura-africana";i:1;s:9:"radiohead";}}
            )
    )

所以我想打印/回显艺术家姓名（“la-semilla-de-la-cultura-africana”和“radiohead”）...我尝试了以下两个：

foreach ($meta['artistName'] as $artist) {
     echo $artist;
}

什么都不打印...或者

foreach ($meta['_artistMeta'] as $artist) {
     echo $artist['artistName'];
}

打印“a”。

如果您能帮助我解决这里的语法问题，我将不胜感激！谢谢！

I'm trying to print the 'artistName' meta keys in a list from the following array:

$postID = $post->ID;
$meta = get_post_meta($postID, $_artistMeta->$postID, TRUE);
print_r($meta);

(which prints the following)

   Array
    (
        [_artistMeta] => Array
            (
                [0] => a:1:{s:10:"artistName";a:2:{i:0;s:33:"la-semilla-de-la-cultura-africana";i:1;s:9:"radiohead";}}
            )
    )

So I want to print/echo the artist names ("la-semilla-de-la-cultura-africana" and "radiohead")... I tried the following two:

foreach ($meta['artistName'] as $artist) {
     echo $artist;
}

which prints nothing... OR

foreach ($meta['_artistMeta'] as $artist) {
     echo $artist['artistName'];
}

which prints "a".

If you can help me with the syntax here, I'd really appreciate it!
Thanks!

你应该使用 unserialize 来取回 php 数组

$postID = $post->ID;
$meta = get_post_meta($postID, $_artistMeta->$postID, TRUE);
$artists = unserialize($meta['_artistMeta'][0]);
foreach ($artists['artistName'] as $artist)
{
     echo $artist;
}

you should use unserialize to get back a php array

$postID = $post->ID;
$meta = get_post_meta($postID, $_artistMeta->$postID, TRUE);
$artists = unserialize($meta['_artistMeta'][0]);
foreach ($artists['artistName'] as $artist)
{
     echo $artist;
}
