我的基本场景如下：
我的服务器上有一个目录，每隔一段时间就会通过ftp充满图像。我想将这些图像移动到wp upload目录，然后使用将其添加到媒体库wp_insert_attachment(). 我想wp_handle_sideload() 这是正确的函数，但如果为其中一个图像提供绝对路径，则返回错误。
以下是我目前的代码：
function oo_attach_images($images, $id){
//$images is an array of anbsolute image paths, $id is the id of a post I want the images to be attached to.
require_once(ABSPATH . \'/wp-admin/includes/file.php\');
require_once(ABSPATH . \'/wp-admin/includes/image.php\');
foreach($images as $image){
$override = array(\'test_form\' => FALSE);
$file = wp_handle_sideload($image, $override);
print_r($file); //returns: Array ( [error] => )
$attachment = array(
\'post_mime_type\' => $file[\'type\'],
\'post_title\' => basename($image),
\'post_content\' => \' \',
\'post_status\' => \'inherit\'
);
$attach_id = wp_insert_attachment( $attachment, $file[\'file\'], $id );
$attach_data = wp_generate_attachment_metadata( $attach_id, $file[\'file\'] );
wp_update_attachment_metadata( $attach_id, $attach_data );
}
}
我研究了类似的问题，但其中列出的解决方案似乎都与侧载本身的失败无关。坦率地说，我认为我没有将正确的文件路径传递给
wp_handle_sideload(), 但由于它在法典中没有记录，我不知道它可能会得到什么样的输入。有人知道我需要做什么改变才能让这一切顺利吗？

这是一段令人惊讶的简单代码，最终实现了它的预期目标：
function oo_attach_images($images, $id){ //$images is an array of image urls, $id is the ID of the post I want the images to be attached to
require_once(ABSPATH . \'/wp-admin/includes/file.php\');
require_once(ABSPATH . \'/wp-admin/includes/media.php\');
require_once(ABSPATH . \'/wp-admin/includes/image.php\');
foreach($images as $image){
$array = array( //array to mimic $_FILES
\'name\' => basename($image), //isolates and outputs the file name from its absolute path
\'type\' => wp_check_filetype($image), // get mime type of image file
\'tmp_name\' => $image, //this field passes the actual path to the image
\'error\' => 0, //normally, this is used to store an error, should the upload fail. but since this isnt actually an instance of $_FILES we can default it to zero here
\'size\' => filesize($image) //returns image filesize in bytes
);
media_handle_sideload($array, $id); //the actual image processing, that is, move to upload directory, generate thumbnails and image sizes and writing into the database happens here
}
}

我使用了Anatol的代码，但在使用HTTP提取图像时遇到了麻烦。要解决此问题，请先使用download\\u url获取图像的本地副本。
了解media\\u handle\\u sideload返回附件id号也很有用，您可以在上载图像后使用该id号显示图像。
foreach($images as $image){
$tmp_name = download_url( $image ); // get the image and save it locally temporarily
$array = array(
\'name\' => basename( $image ),
\'type\' => \'image/jpeg\',
\'tmp_name\' => $tmp_name,
\'error\' => 0,
\'size\' => filesize( $tmp_name )
);
$_image_id = media_handle_sideload($array, $id);
$_src = wp_get_attachment_url( $_image_id );
echo \'<img src="\' . $_src . \'" />\';
}

// determine if in the $media image we created, the string of the URL exists
if(strpos($media, $image[0]) !== false){
// if so, we found our image. set it as thumbnail
set_post_thumbnail($new_post_id, $attachment->ID);

break;
