「WordPress从入门到放弃」QQ交流群:772774006(资源和技术交流)

稍微懂一点SEO优化的朋友应该明白,图片alt和图片title优化是很重要的一项seo优化,

在我们使用WordPress程序做网站时,如果网站的图片数量较多,图片alt和图片title优化是很有必要的,如果我们手动的给每一张图片添加alt属性和图片title属性那会非常麻烦,尤其是图片多的时候。

有人说有WordPress插件可以实现自动添加图片alt和图片title,确实有很多这样的WordPress插件,但是我们本着能不用插件就不用的态度,今天给大家分享一个免插件实现给文章图片自动添加alt和title信息的WordPress优化小技巧

//给文章图片自动添加alt和title信息
add_filter('the_content', 'imagesalt');
function imagesalt($content) {
       global $post;
       $pattern ="/<a(.*?)href=('|\")(.*?).(bmp|gif|jpeg|jpg|png)('|\")(.*?)>/i";
       $replacement = '<a$1href=$2$3.$4$5 alt="'.$post->post_title.'" title="'.$post->post_title.'"$6>';
       $content = preg_replace($pattern, $replacement, $content);
       return $content;
}

使用方法

使用方法很简单,将上面代码复制到主题的functions.php文件,然后刷新网站看看图片的属性,是不是多出了alt和tilte属性呢?
