爲什麼我的標籤有300多個,而WordPress的小工具裏標籤雲的展示上卻只有很少一部分?
我也是很莫名其妙的,不應該啊,查看了後臺發現,確實如此,小工具上標籤雲的展示數量和排序都是無規則的,確實應該有一些可設置的參數,此小工具才更完美啊,話不多說,直接亮代碼了。
/** * 添加新選項到標籤雲小工具 * @param [type] $widget [description] * @param [type] $return [description] * @param [type] $instance [description] * @return [type] [description] */ function cmhello_tag_cloud_new_options( $widget, $return, $instance ) { // Are we dealing with a tag_cloud widget? if ( 'tag_cloud' == $widget->id_base ) { ?> <p> <label for="<?php echo $widget->get_field_id('tags_number'); ?>"><?php _e( '顯示數量:', 'textdomain' ); ?></label> <input type="text" class="widefat" id="<?php echo $widget->get_field_id('tags_number'); ?>" name="<?php echo $widget->get_field_name('tags_number'); ?>" value="<?php if (isset ( $instance['tags_number']) && $instance['tags_number']) echo esc_attr( $instance['tags_number'] ); ?>" /> </p> <p> <label for="<?php echo $widget->get_field_id('orderbytag'); ?>"><?php _e('排序依據:', 'textdomain' ) ?></label> <select class="widefat" id="<?php echo $widget->get_field_id('orderbytag'); ?>" name="<?php echo $widget->get_field_name('orderbytag'); ?>"> <option <?php if ( isset($instance['orderbytag']) && $instance['orderbytag'] == 'name') echo 'selected="SELECTED"'; else echo ''; ?> value="name"><?php echo __('名稱','textdomain');?></option> <option <?php if ( isset($instance['orderbytag']) && $instance['orderbytag'] == 'count') echo 'selected="SELECTED"'; else echo ''; ?> value="count"><?php echo __('數量','textdomain');?></option> </select> </p> <p> <label for="<?php echo $widget->get_field_id('ordertag'); ?>"><?php _e('排序方式:', 'textdomain' ) ?></label> <select class="widefat" id="<?php echo $widget->get_field_id('ordertag'); ?>" name="<?php echo $widget->get_field_name('ordertag'); ?>"> <option <?php if ( isset($instance['ordertag']) && $instance['ordertag'] == 'ASC') echo 'selected="SELECTED"'; else echo ''; ?> value="ASC"><?php echo __('升序','textdomain');?></option> <option <?php if ( isset($instance['ordertag']) && $instance['ordertag'] == 'DESC') echo 'selected="SELECTED"'; else echo ''; ?> value="DESC"><?php echo __('降序','textdomain');?></option> <option <?php if ( isset($instance['ordertag']) && $instance['ordertag'] == 'RAND') echo 'selected="SELECTED"'; else echo ''; ?> value="RAND"><?php echo __('隨機','textdomain');?></option> </select> </p> <?php } } add_filter('in_widget_form', 'cmhello_tag_cloud_new_options', 10, 3 ); /** * 更新標籤雲新字段的值 */ function cmhello_tag_cloud_instance($instance, $new_instance, $old_instance) { $instance['tags_number'] = stripslashes($new_instance['tags_number']); $instance['ordertag'] = stripslashes($new_instance['ordertag']); $instance['orderbytag'] = stripslashes($new_instance['orderbytag']); return $instance; } add_filter('widget_update_callback', 'cmhello_tag_cloud_instance', 10, 3); /** * 通過鉤子去修改標籤雲的參數 * @param [type] $args [description] * @param [type] $instance [description] * @return [type] [description] */ function cmhello_tag_cloud_args( $args, $instance){ if(isset($instance['tags_number'])){ $args['number'] = $instance['tags_number']; //Limit number of tags } if(isset($instance['orderbytag'])){ $args['orderby'] = $instance['orderbytag']; } if(isset($instance['ordertag'])){ $args['order'] = $instance['ordertag']; } return $args; } add_filter('widget_tag_cloud_args', 'cmhello_tag_cloud_args', 10, 2);
代碼來自wp大學,將以上代碼,放入functions.php
即可,最終,呈現的設置效果如下圖
