我嘗試使用檔案中的wp_insert_post功能插入帖子functions.php，帖子成功插入，但不適用于特色圖片的附件。
任何人都可以幫助解決這個問題，我下面的代碼有什么問題：
$post_if = $wpdb->get_var("SELECT count(post_title) FROM $wpdb->posts WHERE post_title like '$title'");
if($post_if < 1){
//coded
$new_post = array(
'post_title' => $title,
'post_content' => $contents,
'post_status' => 'publish',
'post_author' => 1,
'post_type' => 'post'
);
$post_id = wp_insert_post($new_post);
$image = "https://fake.org/image.jpg";
$media = media_sideload_image($image, $post_id); //$post_id from wp_insert_post
// therefore we must find it so we can set it as featured ID
if(!empty($media) && !is_wp_error($media)){
$args = array(
'post_type' => 'attachment',
'posts_per_page' => -1,
'post_status' => 'any',
'post_parent' => $post_id
);
// reference new image to set as featured
$attachments = get_posts($args);
if(isset($attachments) && is_array($attachments)){
foreach($attachments as $attachment){
// grab source of full size images (so no 300x150 nonsense in path)
$image = wp_get_attachment_image_src($attachment->ID, 'full');
// determine if in the $media image we created, the string of the URL exists
if(strpos($media, $image[0]) !== false){
// if so, we found our image. set it as thumbnail
set_post_thumbnail($post_id, $attachment->ID);
// only want one image
break;
}
}
}
}
我嘗試了很多教程，我在網上找到了，沒有任何效果。
請任何有這方面經驗的人可以分享一個解決方案。
太謝謝了
uj5u.com熱心網友回復：
您需要先設定“特色圖片”，然后嘗試查詢它。你試圖做相反的事情。還要在wp_insert_attachment函式中而不是在引數中設定父 ID 。
所以試試這個代碼：
$new_post = array(
'post_title' => $title,
'post_content' => $contents,
'post_status' => 'publish',
'post_author' => 1,
'post_type' => 'post'
);
$post_id = wp_insert_post($new_post);
$image = "https://fake.org/image.jpg";
$attachment_file_type = wp_check_filetype(basename($image), null);
$wp_upload_dir = wp_upload_dir();
$attachment_args = array(
'guid' => $wp_upload_dir['url'] . '/' . basename($image),
'post_title' => preg_replace('/\.[^.] $/', '', basename($image)),
'post_mime_type' => $attachment_file_type['type']
);
$attachment_id = wp_insert_attachment($attachment_args, $image, $post_id);
require_once(ABSPATH . 'wp-admin/includes/image.php');
$attachment_meta_data = wp_generate_attachment_metadata($attachment_id, $image);
wp_update_attachment_metadata($attachment_id, $attachment_meta_data);
set_post_thumbnail($post_id, $attachment_id);
這是檔案頁面
wp_insert_attachment
