php - 以编程方式添加带有附件的 Wordpress 帖子

Question

我在 $_REQUEST 中获取了 post_title、post_content 和其他内容以及图像文件。我想将所有这些作为帖子保存在 wordpress 数据库中。我的页面上有

<?php
require_once("wp-config.php");
$user_ID; //getting it from my function
$post_title = $_REQUEST['post_title'];
$post_content = $_REQUEST['post_content'];
$post_cat_id = $_REQUEST['post_cat_id']; //category ID of the post
$filename = $_FILES['image']['name'];

//I got this all in a array

$postarr = array(
 'post_status' => 'publish',
 'post_type' => 'post',
 'post_title' => $post_title,
 'post_content' => $post_content,
 'post_author' => $user_ID,
 'post_category' => array($category) 
 );
$post_id = wp_insert_post($postarr);

?>

这会将数据库中的所有内容作为帖子获取，但我不知道如何添加附件及其帖子元数据。

我该怎么做？有谁能够帮助我？我真的很困惑，花了几天时间试图解决这个问题。

要添加附件，请使用 wp_insert_attachment():

https://developer.wordpress.org/reference/functions/wp_insert_attachment/

示例:

<?php
  $wp_filetype = wp_check_filetype(basename($filename), null );
  $attachment = array(
     'post_mime_type' => $wp_filetype['type'],
     'post_title' => preg_replace('/\.[^.]+$/', '', basename($filename)),
     'post_content' => '',
     'post_status' => 'inherit'
  );
  $attach_id = wp_insert_attachment( $attachment, $filename, 37 );
  // you must first include the image.php file
  // for the function wp_generate_attachment_metadata() to work
  require_once(ABSPATH . "wp-admin" . '/includes/image.php');
  $attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
  wp_update_attachment_metadata( $attach_id,  $attach_data );
?>

要添加元数据，请使用 wp_update_attachment_metadata():
