主題: [已解決]文章無法顯示，出現fatal error
作者: polaristin 於 七月 13, 2006, 10:19:21 上午
今天發現首頁掛了
http://stin.csie.org/lifetype/
卡在右方的最近文章等等的
好像是文章的地方出了問題
錯誤訊息是
Fatal error: Call to a member function on a non-object in c:\appserv\www\lifetype\class\net\prettyrequestgenerator.class.php on line 40
而去找出line 40是
$permaLink = $this->getBaseUrl()."/post/".$this->_blogInfo->getId()."/".$post->getId();
還是不太能理解哪裡錯
煩請指點 @@
謝謝

你能把那一部份的模版貼出來嗎？看起來是 $post 沒有傳入 ...

mark 是要你貼出出問題地方的模版，就是你的模版裡的 sidebar-l.template 裡的這一段： <!--Top Read Posts-->
{if $topreadposts->isEnabled()}
<h3>熱門文章</h3>
<ul>
{assign var=readposts value=$topreadposts->getTopReadPosts()}
{foreach from=$readposts item=readpost}
<li><a href="{$url->postLink($readpost)}">{$readpost->getTopic()}</a> [{$readpost->getNumReads()} 次]</li>
{/foreach}
</ul>
{/if} 依我判斷，問題出在你的 topreadposts 外掛並沒有傳回任何文章( 就是 $readpost 是 null ) ，所以才會出現錯誤訊息裡那一行： $permaLink = $this->getBaseUrl()."/post/".$this->_blogInfo->getId()."/".$post->getId(); 裡面的 $post 是一個 null 而非物件，才會造成錯誤。 你可以這樣改： <!--Top Read Posts--> {if $topreadposts->isEnabled()} <h3>熱門文章</h3> <ul> {assign var=readposts value=$topreadposts->getTopReadPosts()} {if !empty($readposts) }{foreach from=$readposts item=readpost} <li><a href="{$url->postLink($readpost)}">{$readpost->getTopic()}</a> [{$readpost->getNumReads()} 次]</li> {/foreach} {/if}</ul> {/if} 應該就可以了。 提供詳細資訊，可以省很多事。不是什麼時候都有空可以看這麼仔細的。 lss

不會吧！這是完全不同的問題耶！呵呵！
還好你有去看 plog_articles，否則這問題可能就成了懸案了！
恭喜你解決了！ :-)
