Question

我正在尝试将图片上传到名为＆＃39; event_items＆＃39;的自定义帖子类型。我在那里有一个名为“event-image＆＃39;”的自定义字段。我非常喜欢它去那里，但如果它使用自定义的帖子类型特色图像，那就没问题了。

无法确定如何或在何处添加它。已尝试过示例，但尚未使用过。谢谢。

         <?php
         if(isset($_POST['submit'])){
            $title=$_POST['title'];
            $body=$_POST['body'];
            $news_category=$_POST['region_names'];
            $state=$_POST['state'];

            // Create post object 
$post = array(
  'post_title'    => $title,
  'post_content'  => $body,
  'post_type'     =>'event_items',
  'post_status'   => 'pending',
  'post_author'   => 1
);

     // Insert the post into the database ref.https://codex.wordpress.org/Function_Reference/wp_insert_post
$post_id = wp_insert_post( $post, $wp_error='' );

if($post_id!=0){

     ///upload image ref. 
     https://codex.wordpress.org/Function_Reference/add_post_meta

    ///ref. https://codex.wordpress.org/Function_Reference/wp_handle_upload
    if ( ! function_exists( 'wp_handle_upload' ) ) require_once( ABSPATH . 'wp-admin/includes/file.php' );
$uploadedfile = $_FILES['image'];
$upload_overrides = array( 'test_form' => false );
$movefile = wp_handle_upload( $uploadedfile, $upload_overrides );
if ( $movefile ) {
   // echo "File is valid, and was successfully uploaded.\n";
   var_dump( $movefile);
} else {
    echo "Possible file upload attack!\n";
}


    add_post_meta($post_id, 'event_photo', $movefile['url'] );

如果我做对了，你想支持自定义帖子类型中的精选图片部分，所以你要做的只是将这一行添加到你的functions.php中：

add_post_type_support( 'your Custom Post Type Name', 'thumbnail' );

它会添加精选图片功能，然后您可以在循环“the_post_thumbnail()”或循环外使用get_the_post_thumbnail($post_id);获取缩略图。
