好的，所以我一直在尝试从不同的 div 类中获取特定内容以放入表格中。我正在自定义我的 wordpress 网站。这是我遇到问题的代码
//loops through posts
while ( have_posts() ) : the_post();
$doc = new DomDocument;
$doc ->validateOnParse = true;
$link = " ' " . get_permalink() . " ' ";
//this is where the trouble lies. get error
/*Warning: file_get_contents( ' http://www.uwarc.org/?p=60 ' ) [function.file-get-contents]: failed to open stream: No such file or directory in /home/uwarco5/public_html/wp-content/themes/thesis_185/custom/custom_post_loop.php on line 98

$doc->loadHtml(file_get_contents( $link ));
echo "<tr onclick=" . $quote . "DoNav(". $quote1 . "get_post_class('site', null) " . $quote1. ");" . $quote . ">" ;
echo "<td align =" . $quote . "center" . $quote . " >" ;
echo "<div id =". $quote . "org_logo" . $quote . "> <img src =". $quote ;
var_dump($doc->getElementByClass('img')) ;
echo $quote . "width = ".$quote. '150' . $quote. "; </div> " ;
the_title();
echo "</td>";
echo "<td>" . var_dump($doc->getElementByClass('courses')) . "</td>";
echo "<td>";
var_dump($doc->getElementByClass('description'));
echo "</td>";
echo "</tr>
endwhile;?>
