在模板中使用Wordpress自定义字段复选框

Question

我在Wordpress中创建了一个元框，其中包含自定义字段，包括复选框。我不确定如何检查我的模板中选中了哪个复选框。

自定义字段

array(
                "name"          => "offer-type",
                "title"         => "Type of offer",
                "description"   => "Please select what kind of offer this is",
                "options"       =>  array( "TYPE A","TYPE B"),
                "type"          => "checkbox",
                "scope"         =>  array( "post" ),
                "capability"    => "edit_posts"
),

我的模板循环

    foreach ($posts as $day => $post) {

    // 2 LINES BELOW ARE RELATED TO QUESTION
    $offer_types = unserialize(get_post_meta($post->ID, "_mcf_offer-type", true));


    echo var_dump($offer_types);

我的var转储正在返回＆＃34; false＆＃34; boolean，而它应该返回所选复选框的值。实施有问题吗？

Answer 1

As per our extended discussions, try calling the post via $post('post_id')

I don't think you need the unserialize either.

Your whole line would become:

$offer_types = get_post_meta($post['post_id'], "_mcf_offer-type", true);
