如何从解码的 json - wordpress 中的 PHP 多维数组中获取所需的输出？

Question

我这几天一直在敲我的脑袋，我希望比我聪明得多的人（这并不难，因为我是一个完全的新手）能够阐明我的问题。 我有来自不同 API 的 json 数据，第一个 API 为我提供了产品列表和每个产品单独 API 的路由，然后我使用这些 API 获取数据并将其解码为 wordpress 中的 PHP 多维数组。我需要按特定顺序提取值并添加 html 格式，然后将它们返回到字符串中。

这是我的已解码为数组的 json 提要的简化表示，第一个是我从中提取 API 地址的 json：

{
  "data": [
    {
      "product": "Product A",
      "api": "some/api/feeda",
      "catagory": "some catagory"
    },
    {
      "product": "Product B",
      "api": "some/api/feedb",
      "catagory": "other catagory"
    }
  ]
}

然后检索第二个并返回产品 json：

{
  "data": {
    "title": "Product A",
    "catagory": "Catagory 1",
    "specifications": [
      {
        "detail": "Technical detail 1",
        "notes": "",
        "subDetails": [
          {
            "width": "A not so wide version",
            "height": "This one is shorter"
          },
          {
            "width": "a wider version",
            "height": "a taller version"
          }
        ]
      },
      {
        "detail": "Technical detail 2",
        "notes": "a little bit about detail 2 that is different"
      },
      {
        "detail": "Technical detail 3",
        "notes": "something boring to do with detail 3"
      }
    ]
  }
}

我的目标是仅从选定的类别生成帖子，并使用从“规范”（注释和子详细信息）中提取的标题和 html 格式的内容填充它，以便帖子的内容看起来像这样：

<b>Technical detail 1</b>
A not so wide version
a wider version<br>
<b>Technical detail 2</b>
a little bit about detail 2 that is different<br>
<b>Technical detail 3</b>
something boring to do with detail 3<br>

在我开始使用“wp_insert_post”创建一大堆我不想要的帖子之前，我正在使用“echo”，这样我就可以看到我得到了什么结果。我在 PHP 方面已经做到了这一点，并设法为每个产品标题创建了一个列表，但我尝试的其他方法均无效（我确实设法在列表中获得了产品规格，但它们是错误的规格！）

    function product_list($productlist$) {
            $url_request = wp_remote_get('https://main/api/products/v1/all');
            if (is_wp_error($url_request)) {
                return false; // Bail early
            }
            $body = wp_remote_retrieve_body($url_request);
            $url_json = json_decode($body, true);
            $url_data = $url_json['data'];
            if (!empty($url_data)) {
                foreach($product_url as $product) {
                    $singleproduct_url = $product["url"];
                    $singleproduct_urlrequest = wp_remote_get('https://main/api/products/v1'.$single_product_url.
                        '');
                    $singleproduct_body = wp_remote_retrieve_body($singleproduct_urlrequest);
                    $singleproduct_json = json_decode($singleproduct_body, true);
                    $singleproduct_data = $singleproduct_json['data'];
                    $productspecs = $singleproduct_data['specifications'];
                    foreach($productspecs as $productspec) {
                        $specdetail = "<br>".$productspec["detail"];
                        $subdetails = $productspec['subDetails']
                        if (!empty($productspec['note'])) {
                            $productnote = $productspec['note'];
                        } else {
                            foreach($subdetails as $subdetail) {
                                $subdetailtext = $subdetails[width];
                            }
                        };

                        echo '<li>';
                        echo $singleproduct_data["title"];
                        echo $productnote;
                        echo '</li>';
                    }
                    echo '</ul>';
                }
            }

任何帮助将不胜感激！！！

所以我试图解决你的问题并想出了这个功能，我使用了你的产品 json。请尝试一下，让我知道它是否适合您。

$api_json = '{
  "data": [
    {
      "product": "Product A",
      "api": "some/api/feeda",
      "catagory": "some catagory"
    },
    {
      "product": "Product B",
      "api": "some/api/feedb",
      "catagory": "other catagory"
    }
  ]
}';

$product_json = '{
  "data": {
    "title": "Product A",
    "catagory": "Catagory 1",
    "specifications": [
      {
        "detail": "Technical detail 1",
        "notes": "",
        "subDetails": [
          {
            "width": "A not so wide version",
            "height": "This one is shorter"
          },
          {
            "width": "a wider version",
            "height": "a taller version"
          }
        ]
      },
      {
        "detail": "Technical detail 2",
        "notes": "a little bit about detail 2 that is different"
      },
      {
        "detail": "Technical detail 3",
        "notes": "something boring to do with detail 3"
      }
    ]
  }
}';

function generate_posts($product_json, $category){

    $product_arr = json_decode($product_json, true);

    if($product_arr['data']['catagory'] == $category){
        $result = '';
        foreach($product_arr['data']['specifications'] as $spec){
            $result .= "<b>{$spec['detail']}</b> \r\n";
            $result .= (!empty($spec['notes']) ? "{$spec['notes']}<br>\r\n" : "");
            if(!empty($spec['subDetails'])){
                foreach($spec['subDetails'] as $k=>$sub){
                    if($k == (count($spec['subDetails']) -1)){
                        $result .= "{$sub['width']}";
                    }else{
                        $result .= "{$sub['width']} \r\n";
                    }
                }
                $result .= "<br> \r\n";
            }
        }
        return $result;
    }
    return false;
}

echo generate_posts($product_json, 'Catagory 1');

输出：

<b>Technical detail 1</b> 
A not so wide version 
a wider version<br> 
<b>Technical detail 2</b> 
a little bit about detail 2 that is different<br>
<b>Technical detail 3</b> 
something boring to do with detail 3<br>

您可以在此行之后的代码中调用此函数

$singleproduct_body = wp_remote_retrieve_body($singleproduct_urlrequest);
$myProduct = generate_posts($singleproduct_body, $category); //use desired variables
