在我的插件中需要创建两个小部件。一个是“社会等级”，另一个是“个人资料等级”。

这是我在这里使用的代码。

    <?php
    add_action( \'widgets_init\', \'src_load_widgets\' );

function src_load_widgets() {
    register_widget( \'Widget_SRC\' );
}
function src_load_widgets() {
    register_widget( \'Widget_Rank \' );
}

class Widget_SRC extends WP_Widget {

    function Widget_SRC() {

        $widget_ops = array( \'classname\' => \'src\', \'description\' => __(\'Several social networks counts and ranking system\', \'src\') );       
        $control_ops = array( \'width\' => 300, \'height\' => 350, \'id_base\' => \'social-rank\' );        
        $this->WP_Widget( \'social-rank\', __(\'Social Rank\', \'src\'), $widget_ops, $control_ops );
    }


    function widget( $args, $instance ) {
        extract( $args );   
        $title = apply_filters(\'widget_title\', $instance[\'title\'] );    
        echo $before_widget;

        if ( $title )
            echo $before_title . $title . $after_title;

        echo do_shortcode(\'[SocialRank]\');      

        echo $after_widget;
    }

    function update( $new_instance, $old_instance ) {
        $instance = $old_instance;

        $instance[\'title\'] = strip_tags( $new_instance[\'title\'] );
        return $instance;
    }

    function form( $instance ) {

        $defaults = array( \'title\' => __(\'Social Rank\', \'src\'));
        $instance = wp_parse_args( (array) $instance, $defaults ); ?>
        <!-- Widget Title: Text Input -->
        <p>
            <label for="<?php echo $this->get_field_id( \'title\' ); ?>"><?php _e(\'Title:\', \'hybrid\'); ?></label>
