有人能给我一个上传图片的代码吗？我尝试了很多，但没有一个有效，这就是我所拥有的：

    $post = array(
              \'comment_status\' => $comment_status,
              \'ping_status\'    => \'open\',
              \'post_author\'    => $user_id,
              \'post_content\'   => \'\',
              \'post_status\'    => $status,
              \'post_title\'     => $title,
              \'post_type\'      => \'post\',
             );  
            $post_id = wp_insert_post($post);



    if($_FILES[\'image_imagepost\'][\'error\'] == 0) {

            function insert_attachment($file_handler,$post_id,$setthumb=\'false\'){

// check to make sure its a successful upload
if ($_FILES[$file_handler][\'error\'] !== UPLOAD_ERR_OK) __return_false();

require_once(ABSPATH . "wp-admin" . \'/includes/image.php\');
require_once(ABSPATH . "wp-admin" . \'/includes/file.php\');
require_once(ABSPATH . "wp-admin" . \'/includes/media.php\');

$attach_id = ( $file_handler, $post_id );

if ($setthumb) update_post_meta($post_id,\'_thumbnail_id\',$attach_id);
return $attach_id;
            }

我试着发一篇帖子并上传一张图片，帖子还可以，但图片没有上传到媒体上。谢谢

    $upload = wp_upload_bits( $_FILES[\'image\'][\'name\'], null, file_get_contents( $_FILES[\'image\'][\'tmp_name\'] ) );

    $wp_filetype = wp_check_filetype( basename( $upload[\'file\'] ), null );

    $wp_upload_dir = wp_upload_dir();

    $attachment = array(
        \'guid\' => $wp_upload_dir[\'baseurl\'] . _wp_relative_upload_path( $upload[\'file\'] ),
        \'post_mime_type\' => $wp_filetype[\'type\'],
        \'post_title\' => preg_replace(\'/\\.[^.]+$/\', \'\', basename( $upload[\'file\'] )),
        \'post_content\' => \'\',
        \'post_status\' => \'inherit\'
    );

    $attach_id = wp_insert_attachment( $attachment, $upload[\'file\'], $post_id );

    require_once(ABSPATH . \'wp-admin/includes/image.php\');

    $attach_data = wp_generate_attachment_metadata( $attach_id, $upload[\'file\'] );
    wp_update_attachment_metadata( $attach_id, $attach_data );

    update_post_meta( $post_id, \'_thumbnail_id\', $attach_id );

    wp_redirect( site_url() . \'/thank-you/\' );

    die();
}
