你可以在add_attachment 和edit_attachment 动作挂钩和使用PHPexif_read_data() 要将EXIF数据添加到附件的元数据，请执行以下操作：

<?php
add_action( \'add_attachment\', \'wpse302908_add_exif\' );
add_action( \'edit_attachment\', \'wpse302908_add_exif\' );

/**
 * Inserts metadata from an image\'s EXIF data.
 *
 * @param  int $post_id The attachment\'s post ID.
 * @return void
 */
function wpse302908_add_exif( $post_id ) {
    // These are the keys for the data you want from the EXIF data.
    $exif_keys = array( \'key_1\', \'key_2\' );
    $exif_data = exif_read_data( get_attachment_image_url( $attachment_id );
    foreach ( $exif_keys as $exif_key ) {
        update_post_meta( $post_id, $exif_key, $exif_data[ $exif_key ] );
    }

}
