          [type] =&gt; image 
         ) 

       ) 

     ) 

) 

，我需要得到[url]值（在這一個http://mydomain.com/my/link）

我試圖按照教程，並結束了這樣的：

print $row->field_field_slider_link[0]['raw']['url'] 

但我收到此錯誤信息：

Notice: Undefined offset: 0 in include() (line 57 of /var/www/vhosts/clientname/public_html/sites/all/themes/custom/templates/views/ff-nivo-slider/views-view-fields--ff-nivo-slider.tpl.php). 

任何人都可以看到我在這裏做錯了嗎？

你的代碼運行的陣列是不是你所期望的一個。檢查$row->field_field_slider_link的值。有可能是它是一個空陣列。
