我正在尝试使用前端的帖子而不登录将照片上传到 wordpress。首先，我添加了添加帖子的功能，而无需使用插件在 wordpress 中从前端上传照片。现在我正在尝试通过在这个插件上添加一些代码来添加照片上传功能。但是添加代码后它不会上传照片，但它可以成功发布。我不知道我的错在哪里。请帮我。我的代码如下，

function guestposts_shortcode( $atts ) {
    extract ( shortcode_atts (array(
    'cat' => '1',
    'author' => '1',
    'thanks' => get_bloginfo('home'),
), $atts ) );

return '<form enctype="multipart/form-data" class="guests-post" action="'. plugin_dir_url("guest-posts.php") .'guest-posts/guest-posts-submit.php" method="post">    




<strong>' . __('Post Title:', 'guest-posts') . '</strong><br>
<input type="text" name="title" size="60" required="required" placeholder="' .__('Post title here', 'guest-posts') . '"><br>

 <input type="file" name="upload" id="file"><br>

    <strong>' . __('Story', 'guest-posts') . '</strong>
    '. wp_nonce_field() .'
        <textarea rows="15" cols="72" required="required" name="story" placeholder="' . __('Start writing your post here', 'guest-posts') . '"></textarea><br>
    <strong>' . __('Tags', 'guest-posts') . '</strong><br>
        <input type="text" name="tags" size="60" placeholder="' . __('Comma Separated Tags', 'guest-posts') . '"><br><br>
    <strong>' . __('Your Name', 'guest-posts') . '</strong><br>
        <input type="text" name="author" size="60" required="required" placeholder="' . __('Your name here', 'guest-posts') . '"><br>
    <strong>' . __('Your Email', 'guest-posts') . '</strong><br>
        <input type="email" name="email" size="60" required="required" placeholder="' . __('Your Email Here', 'guest-posts') . '"><br>
    <strong>' . __('Your Website', 'guest-posts') . '</strong><br>
        <input type="text" name="site" size="60" placeholder="' . __('Your Website Here', 'guest-posts') . '"><br><br><br>
    <input type="hidden" value="'. $cat .'" name="category"><input type="hidden" value="'. $author .'" name="authorid">
    <input type="hidden" value="'. $thanks .'" name="thanks">
    <input type="hidden" value="'. str_replace('/wp-content/themes', '', get_theme_root()) .'/wp-blog-header.php" name="rootpath">
    <input type="submit" value="' . __('Submit The Post', 'guest-posts') . '"> <input type="reset" value="' . __('Reset', 'guest-posts') . '"><br>
    </form>
    ';
}
add_shortcode( 'guest-posts', 'guestposts_shortcode' );

而这段代码处理从上面的代码发送的数据，

ob_start();
require_once($_POST["rootpath"]);

        if (!function_exists('wp_generate_attachment_metadata')){
            require_once(ABSPATH . "wp-admin" . '/includes/image.php');
            require_once(ABSPATH . "wp-admin" . '/includes/file.php');
            require_once(ABSPATH . "wp-admin" . '/includes/media.php');
        }

$title = $_POST["title"];
$story = $_POST["story"];
$tags = $_POST["tags"];
$author = $_POST["author"];
$email = $_POST["email"];
$site = $_POST["site"];
$authorid = $_POST["authorid"];
$category = $_POST["category"];
$thankyou = $_POST["thanks"];
$path = $_POST["rootpath"];
$nonce=$_POST["_wpnonce"];
$filename=$_FILES["file"]["name"];
//$file=$_FILES["file"];
//Load WordPress
//require($path);

//Verify the form fields
if (! wp_verify_nonce($nonce) ) die('Security check'); 

$new_post = array(
        'post_title'    => $title,
        'post_content'  => $story,
        'post_category' => $category,  // Usable for custom taxonomies too
        'tags_input'    => $tags,
        'post_status'   => 'publish',           // Choose: publish, preview, future,     draft, etc.
        'post_type' => 'post',  //'post',page' or use a custom post type if you want to
        'post_author' => $authorid //Author ID
);
//save the new post
    $post_id = wp_insert_post( $new_post ); 




if ($_FILES) {

            foreach ($_FILES as $file => $array) {
                if ($_FILES[$file]['error'] !== UPLOAD_ERR_OK) {
                    return "upload error : " . $_FILES[$file]['error'];

               }

  $wp_filetype = wp_check_filetype(basename($file ), null );
  $wp_upload_dir = wp_upload_dir();

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


          $attach_id = wp_insert_attachment( $attachment, $file, $post_id );
    $attach_data = wp_generate_attachment_metadata( $attach_id, $file );
        wp_update_attachment_metadata( $attach_id,  $attach_data );


            }   
        }
/* Insert Form data into Custom Fields */
add_post_meta($post_id, 'author', $author, true);
add_post_meta($post_id, 'author-email', $email, true);
add_post_meta($post_id, 'author-website', $site, true);

header("Location: $thankyou");

?>

使用media_handle_upload函数要好得多。使用以下函数上传文件并返回附件ID...

function guestposts_handle_attachment( $file_handler, $post_id ) {

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

    $attachment_id = media_handle_upload( $file_handler, $post_id );

    if( !is_wp_error( $attachment_id ) ) {

        return $attachment_id;

    }

    return false;

}

然后，当您处理表单时，您可以使用此代码执行该功能并使上传的文件成为特色图像...

if( !empty( $_FILES ) ) {

    $attachment_id = guestposts_handle_attachment( 'upload', $post_id );

    if( $attachment_id ) {

        set_post_thumbnail($post_id, $attachment_id);

    }

}

希望有帮助。
