PHP-EWS:在日历项目上设置多个扩展属性 [英] PHP-EWS: Set multiple extended properties on calendar item

问题描述

是否可以使用PHP EWS在日历项上设置多个自定义属性?除了此之外，我没有找到任何文档.检索扩展属性的示例.我能够将其用于单个字段，但是我想知道您是否可以设置多个自定义属性. API 似乎暗示了这种可能性.

Is it possible to set multiple custom properties on a calendar item using PHP EWS? I haven't been able to find any documentation on this except this example of retrieving extended properties. I was able to get it working for a single field, but I'm wondering if you can set multiple custom properties. The API seems to allude to that possibility.

例如，在ExtendedPropertyType.php中定义了以下属性:

For example, the following properties are defined in ExtendedPropertyType.php:

class EWSType_ExtendedPropertyType extends EWSType
{
    /**
     * ExtendedFieldURI property
     *
     * @var EWSType_PathToExtendedFieldType
     */
    public $ExtendedFieldURI;

    /**
     * Value property
     *
     * @var string
     */
    public $Value;

    /**
     * Values property
     *
     * @var EWSType_NonEmptyArrayOfPropertyValuesType
     */
    public $Values;
}

$Values属性似乎是一个数组，但是我无法在其中成功存储任何内容.我的解决方法是将值数组折叠成JSON字符串并将其存储在$Value属性中(请参见下面的答案).那行得通，但感觉有点破旧.有没有更好的办法?

The $Values property appears to be an array, but I was never able to store anything there successfully. My workaround was to collapse an array of values into a JSON string and store it in the $Value property (see my answer below). That works, but it feels a little hackish. Is there a better way?

推荐答案

在此同时，这是我的解决方法(只是相关的部分).将多个值作为JSON字符串存储在$Value属性中:

Here's my workaround in the mean time (just the pertinent pieces). Store multiple values as a JSON string in the $Value property:

在保存日历项时设置属性:

Set the property when saving the calendar item:

// define custom property
$extendedProperty = new EWSType_PathToExtendedFieldType();
$extendedProperty->PropertyName = 'MyCustomProperty';
$extendedProperty->PropertyType = EWSType_MapiPropertyTypeType::STRING;
$extendedProperty->DistinguishedPropertySetId = EWSType_DistinguishedPropertySetIdType::PUBLIC_STRINGS;
$request->Items->CalendarItem->ExtendedProperty = new EWSType_ExtendedPropertyType();
$request->Items->CalendarItem->ExtendedProperty->ExtendedFieldURI = $extendedProperty;

// store custom data as JSON string
$custom_data = array(
    'scheduled_by' => 'staff',
    'send_to' => $users_email
);
$request->Items->CalendarItem->ExtendedProperty->Value = json_encode($custom_data);

在读取日历时检索属性:

Retrieve the property when reading the calendar:

// initialize the request
$request = new EWSType_FindItemType();
$request->Traversal = EWSType_ItemQueryTraversalType::SHALLOW;
$request->ItemShape = new EWSType_ItemResponseShapeType();
$request->ItemShape->BaseShape = EWSType_DefaultShapeNamesType::ALL_PROPERTIES;
$request->ItemShape->AdditionalProperties = new EWSType_NonEmptyArrayOfPathsToElementType();

// get custom property
$extendedProperty = new EWSType_PathToExtendedFieldType();
$extendedProperty->PropertyName = 'MyCustomProperty';
$extendedProperty->PropertyType = EWSType_MapiPropertyTypeType::STRING;
$extendedProperty->DistinguishedPropertySetId = EWSType_DistinguishedPropertySetIdType::PUBLIC_STRINGS;
$request->ItemShape->AdditionalProperties->ExtendedFieldURI = array($extendedProperty);

解码响应中每个日历项的JSON:

Decode the JSON for each calendar item in the response:

// get JSON data from custom property
$custom_data = json_decode($item->ExtendedProperty->Value, true);
