Php 如何从wordpress中的代码中硬编码小部件？

我的站点上有一个小部件，我可以使用小部件区域添加它。然而，我需要硬编码，因为如果我通过小部件添加它，它会出现在30个不同的页面上。在这一点上，我只能转到所有这30页并添加display:none以单独隐藏每一页。那会很糟糕，而且对我的网站的SEO也不好

我知道调用小部件的php文件。以下是该php文件的代码：

[守则]

<?php

add_action('widgets_init', 'register_featured_jobs_widget');
function register_featured_jobs_widget() {
    register_widget('PricerrTheme_featured_jobs');
}

class PricerrTheme_featured_jobs extends WP_Widget {

    function PricerrTheme_featured_jobs() {
        $widget_ops = array( 'classname' => 'featured-jobs', 'description' => 'Show latest featured jobs' );
        $control_ops = array( 'width' => 200, 'height' => 250, 'id_base' => 'featured-jobs' );
        $this->WP_Widget( 'featured-jobs', 'PricerrTheme - Featured Jobs', $widget_ops, $control_ops );
    }

    function widget($args, $instance) {
        extract($args);

        echo $before_widget;

        if ($instance['title']) echo $before_title . apply_filters('widget_title', $instance['title']) . $after_title;
        $limit = $instance['show_jobs_limit'];

        if(empty($limit) || !is_numeric($limit)) $limit = 5;

                 global $wpdb;  
                 $querystr = "
                    SELECT distinct wposts.* 
                    FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta, $wpdb->postmeta wpostmeta2 , $wpdb->postmeta wpostmeta4
                    WHERE wposts.ID = wpostmeta.post_id AND wposts.ID = wpostmeta2.post_id AND wposts.ID = wpostmeta4.post_id
                    AND wpostmeta.meta_key = 'closed' 
                    AND wpostmeta.meta_value = '0' 

                    AND wpostmeta4.meta_key = 'active' 
                    AND wpostmeta4.meta_value = '1'

                    ORDER BY wposts.post_date DESC LIMIT ".$limit;

                 $pageposts = $wpdb->get_results($querystr, OBJECT);

                 ?>

                     <?php $i = 0; if ($pageposts): ?>
                     <?php global $post; ?>
                     <?php foreach ($pageposts as $post): ?>
                     <?php setup_postdata($post); ?>


                     <?php PricerrTheme_small_post(); ?>


                     <?php endforeach; ?>

                     <?php endif; ?>

                     <?php

    <?php

假设您的页面slug是
“我的页面”
，那么您可以在代码开头执行此操作：

<?php

add_action('widgets_init', 'register_featured_jobs_widget');
function register_featured_jobs_widget() {

    if ( is_page( "my_page" ) ){
       register_widget('PricerrTheme_featured_jobs');
    }

}

要在何处显示小部件？请注意，我的意思是你只想在特定页面上显示小部件？？谢谢你的回答。我真的解决了我的问题。我使用了一个Jetpack插件可见性模块，它允许您指定小部件的确切显示位置。就这样：）
