WordPress REST API里增加特色图片地址缩略图 - 5ucms论坛

//API中添加特色图片
function post_fetured_image_json( $data, $post, $context ) {
$featured_image_id = $data->data['featured_media']; // 获取图片ID
$featured_image_url = wp_get_attachment_image_src( $featured_image_id, 'original' ); // 获取图片地址
if( $featured_image_url ) {
$data->data['thumbnailurl'] = $featured_image_url[0];
}
return $data;
}
add_filter( 'rest_prepare_post', 'post_fetured_image_json', 10, 3 );
添加到functions.php就好

function dw_rest_prepare_post( $data, $post, $request ) {
$_data = $data->data;
$params = $request->get_params();
if (has_post_thumbnail($data)) {
//如果有特色缩略图，则输出缩略图地址
$image = wp_get_attachment_image_src( get_post_thumbnail_id($_data['id']), 'full' );
$post_thumbnail_src = $image[0];
} else {
@$output = preg_match_all('/<img.+src=[\'"]([^\'"]+)[\'"].*>/i', $post->post_content, $matches);
if (!empty($matches[1][0])) {
global $wpdb;
$att = $wpdb->get_row($wpdb->prepare("SELECT ID,guid FROM $wpdb->posts WHERE guid LIKE '%s'", $matches[1][0]));
if ($att) {
$post_thumbnail_src = $att->guid;
} else {
$post_thumbnail_src = $matches[1][0];
}
} else {
// 默认图片路径
$post_thumbnail_src = null;
}
}
$_data['thumbnailurl'] = $post_thumbnail_src;
// if ( ! isset( $params['id'] ) ) {

// }
$data->data = $_data;
return $data;
}
