带有上传功能的 WordPress 3.0 自定义帖子类型 [英] WordPress 3.0 custom post type with upload

问题描述

有没有办法在自定义帖子类型编辑页面上插入一个(或多个)上传字段?

Is there a way to insert one (or more) upload field on a custom post type edition page?

我不想使用包含所有字段和内容的 midia 画廊.

I don't want to use the midia gallery with all the fields and stuff.

推荐答案

这是一个相当基本的示例，但它应该可以帮助您；

This is a fairly basic example, but it should get you on your way;

function my_upload_field()
{
    echo '<input type="file" name="my_upload_field" />';
}
add_action('init', create_function('',
    'add_meta_box("my_upload_field", "Upload File", "my_upload_field", "post");'));

function handle_upload_field($post_ID, $post)
{
    if (!empty($_FILES['my_upload_field']['name'])) {
        $upload = wp_handle_upload($_FILES['my_upload_field']);
        if (!isset($upload['error'])) {
            // no errors, do what you like
        }
    }
}
add_action('wp_insert_post', 'handle_upload_field', 10, 2);

查看 add_meta_box 上的代码，并查看 wp_handle_upload()(从 3.0 开始，第 239 行 wp-admin/includes/file.php)了解更多信息.

Check out the codex on add_meta_box, and take a look at wp_handle_upload() (line 239 wp-admin/includes/file.php as of 3.0) for more information.
