使用 Kaltura API 版本访问自定义数据字段:3.1.5 和 PHP

Question

我已经为我的视频创建了一个名为"记录日期"的自定义元数据字段，我想知道如何在按类别对数据进行排序时回显此信息。这是我到目前为止使用的代码片段。

$pager = new KalturaFilterPager();
$pager->pageIndex = "1";
$pager->pageSize = "200";
if(isset($_REQUEST['category'])){
    $category = $_REQUEST['category'];
}
else{
    $category = "";
}
$filter = new KalturaMediaEntryFilter();
$filter->categoriesMatchOr = $category;
$filter->orderBy = KalturaMediaEntryOrderBy::CREATED_AT_DESC;
$entries = $client->media->listAction($filter, $pager);
if (!$entries)
{
   $entries = array();
}
?>
<ol id="list">
<?php 
$count = 0;
foreach ($entries->objects as $entry)
{
 echo '<li id="'.$count.'"><img src="'.$entry->thumbnailUrl.'"/> <strong>Name:</strong> '.$entry->name.' <strong>Record Date:</strong> '.date('m/d/Y', $entry->createdAt).' <strong>Duration:</strong> '.$entry->duration.' sec</li>';
 $count++;
}
?>
</ol>

我想将$entry->createdAt 替换为我的自定义元数据字段值。任何帮助将不胜感激。

我已经通过在foreach()语句中应用KalturaMetadataFilter()来解决问题。这是代码。

foreach ($entries->objects as $entry){
    $filter_meta = new KalturaMetadataFilter();
    $filter_meta->metadataObjectTypeEqual = KalturaMetadataObjectType::ENTRY;
    $filter_meta->objectIdEqual = $entry->id;
    $filter_meta->statusEqual = KalturaMetadataStatus::VALID;
    $metadataPlugin = KalturaMetadataClientPlugin::get($client);
    $result = $metadataPlugin->metadata->listAction($filter_meta);
    //print_r($result);
    if(isset($result->objects[0]->xml)){
        $xml = simplexml_load_string($result->objects[0]->xml);
        $record_date = (int)$xml->RecordDate;
    }
    else{
        $record_date = $entry->createdAt;
    }
    echo '<li id="'.$count.'"><img src="'.$entry->thumbnailUrl.'"/> <strong>Name:</strong> '.$entry->name.' <strong>Record Date:</strong> '.date('m/d/Y', $record_date).' <strong>Duration:</strong> '.$entry->duration.' sec</li>';
    $count++;
}

Answer 2

您应该调用 entry.list，然后用逗号（例如 '0_jhb23ad，0_jhbasd3,0_askdja3'）内爆您在结果中收到的条目 ID，然后调用 metadata.list 在字段 'objectIdIn' 中传递条目 ID 列表。

顺便说一句，你有一个错误——

$filter->orderBy = 'CREATED_AT_DESC';

没有效果，应该是

KalturaMediaEntryOrderBy::CREATED_AT_DESC;
