织梦模板DEDECMS showphoto.php图集页面调用图片的alt信息

  foreach($dtp->CTags as $ctag)
  {
     if($ctag->GetName()=="img")
     {
  if($i==($npos-1)) $preSrc = trim($ctag->GetInnerText());
  if($i==($npos+1)) $nextSrc = trim($ctag->GetInnerText());
  $i++;
     }
  } 核心代码就在这里了，一个foreach循环，自然要修改这里了，修改后如下： 
 
  foreach($dtp->CTags as $ctag)
  {
     if($ctag->GetName()=="img")
     {
  if($i==($npos-1)) $preSrc = trim($ctag->GetInnerText());
  if($i==($npos+1)) $nextSrc = trim($ctag->GetInnerText());
 if($i==$npos) $text = $ctag->GetAtt('text');
  $i++;
     }
  }
