我正在创建一个类别小部件,这样我就可以只在我想要的页面上拥有博客类别,因此它更适合我的主题:)
无论如何,这里是小部件编码,我认为还可以,但我无法测试它,因为我不确定如何调用链接,调用哪一列。
class ubl_blog_cats extends WP_Widget {
public function __construct() {
parent::__construct(
'ubl_blog_cats',
'UBL Blog Categories',
array( 'description' => __( 'Displays The Bog Categories'))
);
}
public function form( $instance ) {
$title = (isset( $instance[ 'title' ])) ? $instance['title' ] : 'Blog Categories'; ?>
<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>
<?php }
public function update( $new_instance, $old_instance ) {
$instance = array();
$instance['title'] = strip_tags( $new_instance['title'] );
return $instance;
}
public function widget( $args, $instance ) {
global $wpdb;
extract( $args );
$title = apply_filters( 'widget_title', $instance['title'] );
if ( ! empty( $title ) ) echo '<div class="widget_title" id="widget">' . $title . '</div>';
$ublmostpop = new $wpdb->get_results("
SELECT *
FROM wp_term_relationships
LEFT JOIN wp_term_taxonomy
ON (wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id)
LEFT JOIN wp_terms on wp_term_taxonomy.term_taxonomy_id = wp_terms.term_id
WHERE wp_term_taxonomy.taxonomy = 'category'
GROUP BY wp_term_taxonomy.term_id");
echo '<div class="navcat"><ul>';
foreach($ublmostpop as $ublmp){ ?>
<li><a href="" title=""></a></li>
<?php } ?>
</ul></div>
<?php
wp_reset_postdata();
echo $after_widget;
}
}
register_widget( 'ubl_blog_cats' );
?>
另外请让我知道这个小部件是否不起作用:)
