我正在尝试生成自定义array 从PHP函数传递wp_localize_script 但我似乎无法设置页面条件。

我有以下功能：

function mb_scripts_settings() {

    // blanks
    $mb_ajax_form_type = $mb_get_page_slug = $mb_redirect = $mb_redirect_time = $mb_form_disable = $mb_array = \'\';


    // get the form type
    $mb_ajax_form_type      = ( is_front_page() ? \'change\'  : \'submit\'  );

    // get the page
    $mb_get_page_slug       = get_page_link();

    // generate the url for redirection
    $mb_form_area           = ( ( is_page(\'admin\') && isset($_GET[\'mbtab\']) )   ? $_GET[\'mbtab\']    : null  );
    $mb_form_area_url       = ( empty($mb_form_area)    ? \'/\' : \'/admin/?mbtab=\' . $mb_form_area . \'&mbform=1\'          );

    // if the page is admin
    if( is_page(\'admin\') ) {
        $mb_redirect        = true;
        $mb_redirect_time   = 3000;
        $mb_form_disable    = true;
    }

    // if the page is password set
    if( is_page(\'pw\') ) {
        $mb_redirect        = true;
        $mb_redirect_time   = 3000;
        $mb_form_disable    = true;
    }

    // if the page is front
    if( is_page(\'pw\') ) {
        $mb_redirect        = false;
        $mb_redirect_time   = 0;
        $mb_form_disable    = false;
        $mb_form_area = $mb_form_area_url = \'\';
    }

    // build the array
    $mb_array = array( $mb_ajax_form_type, $mb_get_page_slug, $mb_redirect, $mb_redirect_time, $mb_form_disable );

    return $mb_array;
}

然而，我收到一个错误，说我不能打电话is_front_page 或is_page 循环外部。

Notice: is_front_page was called incorrectly. Conditional query tags do not work before the query is run. Before then, they always return false. Please see Debugging in WordPress for more information. (This message was added in version 3.1.0.)

我试图通过获取页面id和其中的slug来实现这一点，但它没有返回任何结果-在mb_get_page_slug

function mb_scripts() {
    wp_enqueue_script( \'mbtheme_js\', mbWebOS_js . \'theme-scripts. \'.js\' );
    wp_localize_script( \'mbtheme_js\', \'mbtheme_js\', mb_scripts_settings() );
}

add_action( \'wp_enqueue_scripts\',   \'mb_scripts\'        );

// set up the settings for the theme.js
function mb_scripts_settings() {

    // blanks
    $mb_ajax_form_type = $mb_get_page_slug = $mb_redirect = $mb_redirect_time = $mb_form_disable = $mb_array = \'\';

    // get the form type
    $mb_ajax_form_type      = ( is_front_page() ? \'change\'  : \'submit\'  );

    // get the page slug from ID
    $mb_get_page_slug       = get_post_field( \'post_name\', get_the_ID() );

    // if the page is admin or password
    if( is_page( array(\'admin\', \'pw\') ) ) {
        $mb_redirect        = true;
        $mb_redirect_time   = 3000;
        $mb_form_disable    = true;

        if( is_page(\'admin\') ) {
            // generate the url for redirection
            $mb_form_area           = ( ( is_page(\'admin\') && isset($_GET[\'mbtab\']) )   ? $_GET[\'mbtab\']    : null      );
            $mb_form_area_url       = ( empty($mb_form_area)    ? \'/\' : \'/admin/?mbtab=\' . $mb_form_area . \'&mbform=1\'  );
            $mb_form_area_url       = get_home_url( $mb_form_area_url );
        }
    }

    // if the page is front
    if( is_front_page() ) {
        $mb_redirect        = false;
        $mb_redirect_time   = 0;
        $mb_form_disable    = false;
        $mb_get_page_slug   = \'front_page\';
        $mb_form_area = $mb_form_area_url = null;
    }

    // build the array
    $mb_array = array(
                $mb_ajax_form_type,
                $mb_get_page_slug,
                $mb_redirect,
                $mb_redirect_time,
                $mb_form_disable
            );

    return $mb_array;
}

    // enqueue the theme js
    wp_enqueue_script( \'mb_mbtheme_js\', mbWebOS_js . \'scripts.\' . $mbTheme . \'.js\' );

    // localise the theme js
    // only for selected pages
    if( is_page(\'admin\') || is_front_page() ) {
        wp_localize_script( \'mb_mbtheme_js\', \'mb_mbtheme_js\', mb_scripts_settings() );
    }
