phpcms 文章内容图片缩略方法

在/phpcms/modules/content/index.php中修改

方法就是匹配出img 图片地址,用thumb进行缩放替换在展现出来。

?

在show()方法中,修改$content

?

content = preg_replace('/<img [^ alt=" phpcms  文章内容图片缩略步骤 " >]*src=[\'"]?([^>\'"\s]*)[\'"]?[^>]*>/ie',"self::changeThumb('$0','$1')",$content);
Copy after login

匹配图片,交给本身类函数 changgeThumb操作,$0,匹配整个img代码,$1匹配出图片url地址

?

?

protected static function changeThumb($old,$path){
       $width = 580;
        //传递过来的字符串有转义,去掉
       $old = str_replace('\"','"', $old);
       //本身自带的thumb函数,不陌生
       $new = str_replace($path, thumb($path,$width,0), $old);
      return  $new;
}
Copy after login

?好了,这样可以看看你页面中的图片是不是都变成缩略图片了,
