需要帮助使用来自 JSON 的 wp_insert_post 创建帖子

Question

我正在尝试使用 wp_insert_post 将 JSON 插入 wordpress。我撞到了一堵砖墙。我的代码和我的一些 json 可以在下面看到。

PHP：

<?php
$json_feed = "http://localhost/sample/ss-posts.json";
$json = file_get_contents($json_feed);
$obj = json_decode($json, true);

foreach($obj as $article_array){
    $url = $article_array['url'];
    $title = $article_array['title'];
    $category = $article_array['category'];
    $large_summary = $article_array['wp_post_content'];

    $post = array(
        'post_title' => $title,
        'post_content' => $large_summary,
        'post_status' => 'publish',
        'post_type' => 'post',
        'comment_status' => 'closed',
        'post_template' => 'content.php'
        );

    wp_insert_post ($post, $wp_error);
}
?>

JSON数据：

{
    "post":[
        {
            "title":"Choir to College to Commercial",
            "wp_post_title":"Choir to College to Commercial",
            "wp_post_content":"My entry into the world of music..."
        },
        {
            "title":"How to Master Vocal Technique",
            "wp_post_title":"How to Master Vocal Technique",
            "wp_post_content":"Acquiring command over vocal technique is like ..."
        },
        {
            "title":"How Do You Evaluate Singers?",
            "wp_post_title":"How Do You Evaluate Singers?",
            "wp_post_content":"Many lovers of singing say that they can't put to words ..."
        }
    ]
}

错误：运行此代码时，我收到以下“警告：在第 6 行的 /Users/andrew/Desktop/newtest.php 中为 foreach() 提供的参数无效”。

添加foreach((array)$obj as $article_array){...}时没有错误

在 if (is_object($obj)){...} 语句中包装整个 foreach 循环时也没有错误。

任何帮助或建议将不胜感激。提前致谢！

由于 JSON 对象的结构是 { "post":[ {}, {}, ... ] }，因此使用 json_decode 的结果将是 $obj['post'][ Array, Array, ... ]。因此，在foreach 循环中，您必须遍历$obj['post'] 数组而不是$obj

所以 foreach 必须是：

...
foreach($obj['post'] as $article_array){
...
