尝试挂接到“save\\u post”操作：

add_action( \'save_post\', \'your_state_term_save\' );

function your_state_term_save( $post_id ){

    // Bail if we\'re doing an auto save
    if( defined( \'DOING_AUTOSAVE\' ) && DOING_AUTOSAVE ) return;

    //check if they selected your state term
    $state = isset($_POST[\'tax_input_field_name\']) ? $_POST[\'tax_input_field_name\'] : \'\'; //make sure of what the input name is here...

    //insert post meta
    update_post_meta($post_id,\'state\',$state);
}
