PHP意外的'register_nav_menus‘

Question

当我尝试将以下代码放入我的functions.php中时：

register_nav_menus(array(
'primary' => __('Primary Menu'),
'footer' => __('Footer Menu')
));

它返回给我以下错误：

分析错误:语法错误，意外的'register_nav_menus‘(T_STRING)

这是标题部分：

<nav class="site-nav">

            <?php

                $args = array(
                    'theme_location' => 'primary'
                );
            ?>


            <?php wp_nav_menu($args); #creates the menu according to my pages section?>
        </nav>

和页脚：

<nav class="site-nav">
        <?php
            $args = array(
                'theme_location' => 'footer'
            );
        ?>

        <?php wp_nav_menu($args); ?>
</nav>

Answer 1

首先，你需要在after_setup_theme钩子上注册你的菜单

/********* After Setup Theme ***********/
add_action('after_setup_theme', 'my_theme_theme_setup');

if ( ! function_exists( 'my_theme_theme_setup' ) ){
    function my_theme_theme_setup(){

        add_action('init', 'my_theme_register_my_menus');

        if ( ! function_exists( 'my_theme_register_my_menus' ) ){
            function my_theme_register_my_menus(){
                register_nav_menus(array(
                    'header-menu'  => esc_html__('Header Menu', 'my_theme'),
                    'footer-menu'  => esc_html__('Footer Menu', 'my_theme'),
                ));
            }
        }
    }
}

然后像这样使用它(这可以修改)

wp_nav_menu( array( 'theme_location' => 'header-menu', 'container' => false, 'menu_id' => 'main_menu', 'menu_class' => '', 'fallback_cb' => false ) )

您有未定义的错误，因为您只是直接转到并注册菜单，而没有将它们附加到挂钩。

Answer 2

您是否忘记了在functions.php中的前一行以分号结束？我敢打赌一定有一个；缺少;)

Answer 3

你的function.php就像这样，你忘记了那个错误抛出的add_action()分号。

add_action('wp_enqueue_scripts','learningWordPress_resources')**;**


// Navigation Menus
register_nav_menus(array(
'primary' => __('Primary Menu'),
'footer' => __('footer Menu'),
));
