它看起来像一个bug，但添加了在中修改的post\\uwp_insert_post 不工作：

$wp_test = array(
  \'post_title\'        => \'test\',
  \'post_content\'      => \'test\',
  \'post_status\'       => \'publish\',
  \'post_type\'         => \'test\',
  \'post_author\'       => 1,
  \'post_date\'         => \'2015-01-22 22:00:12\',
  \'post_date_gmt\'     => \'2015-01-22 22:00:12\',
  \'post_modified\'     => \'2016-04-18 12:12:12\',
  \'post_modified_gmt\' => \'2016-04-18 12:12:12\',
  \'comment_status\'    => \'closed\'
);
$wp_id = wp_insert_post( $wp_test );

post\\u修改日期不起作用，并获得与post\\u日期相同的值，而不是所希望的“2016-04-18 12:12:12”。这是虫子吗？我正在使用wp 4.5（二十一六主题）。我使用以下代码修复了它，但我认为它可能更实用。。。

$wp_test = array(
  \'post_title\'        => \'test\',
  \'post_content\'      => \'test\',
  \'post_status\'       => \'publish\',
  \'post_type\'         => \'test\',
  \'post_author\'       => 1,
  \'post_date\'         => \'2015-01-22 22:00:12\',
  \'post_date_gmt\'     => \'2015-01-22 22:00:12\',
  \'comment_status\'    => \'closed\'
);
$wp_id = wp_insert_post( $wp_test );

// ugly fix
$wpdb->query( "UPDATE $wpdb->posts SET post_modified = \'2016-04-18 12:12:12\',post_modified_gmt = \'2016-04-18 12:12:12\' WHERE ID = $wp_id");

if ( $update || \'0000-00-00 00:00:00\' == $post_date ) {
        $post_modified     = current_time( \'mysql\' );
        $post_modified_gmt = current_time( \'mysql\', 1 );
} else {
        $post_modified     = $post_date;
        $post_modified_gmt = $post_date_gmt;
}

add_filter( \'wp_insert_post_data\', \'alter_post_modification_time\', 99, 2 );
$wp_id = wp_insert_post( $wp_test );
remove_filter( \'wp_insert_post_data\', \'alter_post_modification_time\', 99, 2 );

function alter_post_modification_time( $data , $postarr ) {
    if (!empty($postarr[\'post_modified\']) && !empty($postarr[\'post_modified_gmt\'])) {
        $data[\'post_modified\'] = $postarr[\'post_modified\'];
        $data[\'post_modified_gmt\'] = $postarr[\'post_modified_gmt\'];
    }

    return $data;
}
