dedecms5.6将文章和图集里的图片的ALT注释说明改成文章标题
对于一个
SEO
高手来说,每个细节都相当重要。本文介绍如何将文章里的图片的注释改成文章标题,如此一来,对搜索引擎会更加友好。如果只想加文章的就把带imgurls的三行去掉即可。修改文件:Include/ arc.archives.class.php
查找以下代码:
$this->Fields['typename'] = $this->TypeLink->TypeInfos['typename']; @SetSysEnv($this->Fields['typeid'],$this->Fields['typename'], $this->Fields['id'],$this->Fields['title'],'archives');
在以下添加代码:
$this->Fields['body'] = str_ireplace(array('alt=""','alt=\'\''),'', $this->Fields['body']); $this->Fields['body'] = preg_replace("@ [\s]{0,} alt[\s]{0,}=[\"'\s]{0,}[\s\S]{0,}[\"'\s] @isU"," ",$this->Fields['body']); $this->Fields['body'] = str_ireplace("<img " , "<img alt=\"".$this->Fields['title']."\" ",$this->Fields['body']); $this->Fields['imgurls'] = str_ireplace(array('alt=""','alt=\'\''),'' ,$this->Fields['imgurls']); $this->Fields['imgurls'] = preg_replace("@ [\s]{0,}alt[\s]{0,} =[\"'\s]{0,}[\s\S]{0,}[\"'\s] @isU"," ",$this->Fields['imgurls']); $this->Fields['imgurls'] = str_ireplace("<img " , "<img alt=\"".$this->Fields['title']."\" ",$this->Fields['imgurls']); //替换图片Alt为文档标题
改完以后直接生成全站就OK了,对图片多的站来说还是很重要的,图片的alt标签不容忽视。生成以后我发现一个问题,就是图片的注变成了alt='文章标题' 但是百度的规范应该是 alt="文章标题"。
解决办法: 你代码的最后一行
$this->Fields['body'] = str_ireplace("<img " , "<img alt='".$this->Fields['title']."' ",$this->Fields['body']);
改为
$this->Fields['body'] = str_ireplace("<img " , "<img alt=\"".$this->Fields['title']."\" ",$this->Fields['body']);
单引号改为双引号并在前面加 \
