问题描述

我试图通过 PHP 获取并将图像插入 wordpress 环境之外的自定义帖子。

如何移动/上传该图像到 wordpress 上传目录年份日期文件夹格式就像 wordpress 做，并将该图像设置为特色图像反对定制的帖子？

还要将图片上传到自定义展示廊？

以下是我的代码

$filename = $image['name'];
$target_path = "../wp-content/uploads/";
$target_path = $target_path . $filename;
$wp_filetype = wp_check_filetype(basename($filename), null );
$wp_upload_dir = wp_upload_dir();
$attachment = array(
    'guid' => $wp_upload_dir['baseurl'] . '/' . basename( $filename ),
    'post_mime_type' => $wp_filetype['type'],
    'post_title' => preg_replace('/.[^.]+$/', '', basename($filename)),
    'post_content' => '',
    'post_status' => 'inherit',
);
$attach_id = wp_insert_attachment( $attachment, $target_path, $post_id );
$attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
wp_update_attachment_metadata( $attach_id, $attach_data );
set_post_thumbnail( $post_id, $attach_id );

我设法将图像上传到我的 uploads 目录，但无法创建年份和日期文件夹。这有什么 wp 功能吗？

最佳解决方案

这不能简单地用 media_sideload_image()完成吗？

似乎很简单只有在不在管理区域的情况下，您必须在 WordPress 中包含一些库，包括：

// only need these if performing outside of admin environment
require_once(ABSPATH . 'wp-admin/includes/media.php');
require_once(ABSPATH . 'wp-admin/includes/file.php');
require_once(ABSPATH . 'wp-admin/includes/image.php');

// example image
$image = 'http://example.com/logo.png';

// magic sideload image returns an HTML image, not an ID
$media = media_sideload_image($image, $post_id);

// 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;
            }
        }
    }
}
