I am having trouble when uploading media to a WordPress site with the JSON REST API.
With the following code I can upload the photos, but no info is assigned to them, not even the name - in fact the name automatically becomes the URL and filename (without the extension).
$username = "ZX";
$password = "ZX";
$host = '';
$data = json_encode($data);
$file = '/Users/xx.png';
$imagedata = file_get_contents($file);
$process = curl_init($host);
curl_setopt($process, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($process, CURLOPT_BINARYTRANSFER, TRUE);
curl_setopt($process, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($process, CURLOPT_TIMEOUT, 50);
curl_setopt($process, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($process, CURLOPT_POSTFIELDS, $data);
curl_setopt($process, CURLOPT_HTTPHEADER, array('Content-Type:image/png','Content-Disposition:attachment;filename='.$file));
$return = curl_exec($process);
print_r($return);
How would I assign data, like the following, to the uploads?
$data = array(
"status" => "draft",
"title" => "Photo media",
"description" => "Photo media1",
"media_type" => "image",
"alt_text" => "alternate text"
);

Reset to default 3This is not possible via the API; you need to fetch the image yourself, and send the data to the API yourself. Blockquote

How to side load images
Note that the media_sideload_image() return value can be an instance of \WP_Error as well. You then just need to attach it to a post, which is quite simple:
$media = media_sideload_image(
'http://i.imgur/bcJvAj0.jpg',
$post->ID,
'Some image description',
'src'
);
if ( ! empty( $media ) and ! is_wp_error( $media ) ) {
// reference new image to set as featured
$attachments = get_posts( [
'post_type' => 'attachment',
'posts_per_page' => 1,
'post_status' => 'any',
'post_parent' => $post->ID,
] );
if ( is_array( $attachments ) ) {
set_post_thumbnail( $post->ID, $attachments[0]->ID );
}
// Test print our image. The return value is the src of the sideloaded image.
printf( '<img src="%s" />', $media );
}
The internals
A short back trace through core that explains why you should stick with the API:
Take a look at the source of media_sideload_image() to see it uses download_url() internally, which uses wp_safe_remote_get(), a wrapper for \WP_HTTP::get(). This means it offers the whole WP API while being quite safe, debuggable and easy to use. The return value of download_url() is the result of wp_tempnam(), which takes all possible /tmp locations into account (there are plenty) and makes sure your location is writeable. The media_handle_sideload() will generate all needed attachment data and meta data.
