Question

我的网站上有一个可以使用Widgets区域添加的小部件。但是，我需要对其进行硬编码，因为如果我通过Widgets添加它，它会出现在30个不同的页面上。此时我只能访问所有这30个页面并添加display：none来单独从每个页面中隐藏它。那会很糟糕，这对我网站的搜索引擎优化会有害......

我知道调用小部件的php文件。这是php文件的代码：

[代码]

<?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' 

                    AND wpostmeta2.meta_key = 'featured' 
                    AND wpostmeta2.meta_value = '1' AND 

                    wposts.post_status = 'publish' 
                    AND wposts.post_type = 'job' 
                    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 else : ?> <?php $no_p = 1; ?>
                       <div class="padd100"><p class="center"><?php _e("Sorry, there are no posted jobs yet.",'PricerrTheme'); ?></p></div>

                     <?php endif; ?>

                     <?php

        echo $after_widget;
    }

    function update($new_instance, $old_instance) {

        return $new_instance;
    }

    function form($instance) { ?>

            <label for="<?php echo $this->get_field_id('title'); ?>"><?php _e('Title'); ?>:</label>
            <input type="text" id="<?php echo $this->get_field_id('title'); ?>" name="<?php echo $this->get_field_name('title'); ?>" 
            value="<?php echo esc_attr( $instance['title'] ); ?>" style="width:95%;" />
        </p>


        <p>
            <label for="<?php echo $this->get_field_id('show_jobs_limit'); ?>"><?php _e('Show jobs limit'); ?>:</label>

            value="<?php echo esc_attr( $instance['show_jobs_limit'] ); ?>" style="width:20%;" />
        </p>




    <?php 
    }
}



?>

[代码]

我尝试从代码中复制各种部分并将它们放在我需要放置小部件的位置，但我无法使其工作。我尝试的所有内容都会在我的网站上显示实际代码，或者打破页面。

有人可以帮忙吗？谢谢。

假设您的页面标记为"my_page"，那么您可以在代码的开头执行此操作：

<?php

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

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

}

这将在该特定页面上注册您的小部件。

来自wordpress的文档：is_page()

如何在wordpress中使用此代码硬编码小部件？
