wordpress圣经 的源码 有问题吗?
wordpress 圣经 在讲Chapter 5: Extending WordPress with Plugins时,有个例子,我在试用时出现这样的问题,请高手指点:
Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'copyright-notices' not found or invalid function name in E:\xampp\htdocs\chinese\wp-includes\plugin.php on line 405:

call_user_func_array($the_['function'], array_slice($args, 0, (int) $the_['accepted_args']))

附原码:

/*

Plugin Name: Copyright Notices

Plugin URI: http://emmense.com/copyright-notices/

Description: A plugin that allows the user to set Copyright text in the theme and control it from WordPress Admin.

Author: Aaron Brazell

Version: 1.0

Author URI: http://technosailor.com/

function i18n_copyright()

{

$plugin_path = plugin_basename( dirname( __FILE__ ) .'/translations' );

load_plugin_textdomain('copyright-notices', $plugin_path );

}

add_action('init','i18n_copyright');



function copyright_notices_admin_page() {

add_submenu_page( 'plugins.php',__('Copyright Notices Configuration'), __('Copyright Notices Configuration','copyright-notices'), 0, 'manage_options', 'copyright-notices', 'copyright_notices_admin');

}

add_action('admin_menu', 'copyright_notices_admin_page');

function copyright_notices_admin()

{

if( $_POST['submit'] )

{

if( check_admin_referer('copyright_notices_admin_options-update') )

{

$options_saved = false;

if( $oldvalue = get_option('copyright_notices_text') )

{

update_option( 'copyright_notices_text', $_POST['copyright_text'] );

if( $oldvalue == get_option('copyright_notices_text') )

{

$options_saved = true;

}

}

else

{

if( add_option( 'copyright_notices_text', $_POST['copyright_text'] ) )

{

$options_saved = true;

}

}

}

}

if( $options_saved )

{

echo '

' . __('Options Saved','copyright-notices') . '.

';

}



?>
