Wp meta value for dropdown box in custom post

Question

I have added one custom post in admin side for adding session details.Inside session post i want to add a speaker data by using dropdown box.but the data is stored in the post meta as "a:2:{i:0;s:2:"91";i:1;s:3:"105";}"

Here 91 and 105 are the ID's of speaker post.

Can anyone suggest me how can parse the data from the metadata.

您的扬声器元数据采用序列化格式。只需使用get_post_meta( $session_id, '_speaker_meta_id', true );，您就可以将扬声器数据作为数组获得，然后您可以随心所欲地执行任何操作。 get_post_meta()自动反序列化序列化数据。
