您应该将所有边栏注册为一个函数，并将它们挂接到widgets\\u init中。

如果你想摆脱<div class="text_widget"> </div> 您必须编写自己的文本小部件，因为它没有过滤器。

在wp中包括/默认小部件。php文本小部件是如何构建的：

/**
 * Text widget class
 *
 * @since 2.8.0
 */
class WP_Widget_Text extends WP_Widget {

    function WP_Widget_Text() {
        $widget_ops = array(\'classname\' => \'widget_text\', \'description\' => __(\'Arbitrary text or HTML\'));
        $control_ops = array(\'width\' => 400, \'height\' => 350);
        $this->WP_Widget(\'text\', __(\'Text\'), $widget_ops, $control_ops);
    }

    function widget( $args, $instance ) {
        extract($args);
        $title = apply_filters( \'widget_title\', empty($instance[\'title\']) ? \'\' : $instance[\'title\'], $instance, $this->id_base);
        $text = apply_filters( \'widget_text\', $instance[\'text\'], $instance );
        echo $before_widget;
        if ( !empty( $title ) ) { echo $before_title . $title . $after_title; } ?>
            <div class="textwidget"><?php echo $instance[\'filter\'] ? wpautop($text) : $text; ?></div>
        <?php
        echo $after_widget;
    }

    function update( $new_instance, $old_instance ) {
        $instance = $old_instance;
        $instance[\'title\'] = strip_tags($new_instance[\'title\']);
        if ( current_user_can(\'unfiltered_html\') )
            $instance[\'text\'] =  $new_instance[\'text\'];
        else
            $instance[\'text\'] = stripslashes( wp_filter_post_kses( addslashes($new_instance[\'text\']) ) ); // wp_filter_post_kses() expects slashed
        $instance[\'filter\'] = isset($new_instance[\'filter\']);
        return $instance;
    }

    function form( $instance ) {
        $instance = wp_parse_args( (array) $instance, array( \'title\' => \'\', \'text\' => \'\' ) );
        $title = strip_tags($instance[\'title\']);
        $text = esc_textarea($instance[\'text\']);
?>
        <p><label for="<?php echo $this->get_field_id(\'title\'); ?>"><?php _e(\'Title:\'); ?></label>
        <input class="widefat" id="<?php echo $this->get_field_id(\'title\'); ?>" name="<?php echo $this->get_field_name(\'title\'); ?>" type="text" value="<?php echo esc_attr($title); ?>" /></p>
