Question

我有这个片段（我想从.xml文件中获取元素）：

$movies = simplexml_load_file('http://www.example.com/example.xml');
$out = "";

foreach ($movies as $movie) {
    $properties = array(
        'photo'   => $movie->image,
        'title'   => $movie->title,
        'desc'    => $movie->teaser,
        'channel' => $movie->channel,
        'date'    => $movie->date);

    $out .= $modx->getChunk('tpl_movies-item', $properties);
}

return $out;

和chunk tpl_movies-item：

<article>
    [[+photo]]
    [[+title]]
    [[+desc]]
    [[+date]]
    [[+channel]]
    aaa
</article>

它仅显示＆＃34; aaa＆＃34; （但是当我将数组中的值更改为字符串时，例如，当我添加＆＃34; echo $ properties [＆＃39; photo＆＃39;]＆＃34;它打印正确的值）时＆＃39;降序＆＃39; =＆GT; ＆＃34; lololololol＆＃34;它运作正常。你能帮帮我，我该怎么办？

问题可能出在你的foreach语句中，因为simplexml_load_file()需要->children()来遍历手头对象的不同子节点。尝试：

foreach ($movies->children() as $movie) {
    $properties = array(
        'photo'   => (string)$movie->image,
        'title'   => (string)$movie->title,
        'desc'    => (string)$movie->teaser,
        'channel' => (string)$movie->channel,
        'date'    => (string)$movie->date);

    $out .= $modx->getChunk('tpl_movies-item', $properties);
}

尝试将属性转换为string，如上例所示，因为它们可以作为对象返回。

Chunk没有看到论点
