WordPress图片地址在默认编辑下是使用额绝对路径,这样别人复制你文章到其他的网站上,图片也可以正常显示,但是如果我想更改博客的域名,或者路径,那么这些图片的地址全部失效,不能正常显示。优搜网在网上找到两种解决Wordpress模板图片使用相对路径的方法,希望可以帮到大家。
1.修改Wordpress主题根目录下的wp-config.php,这个文件只有在安装好Wordpress之后才会出现,在该文件中加入一下两行
define(‘WP_HOME’, ”);
define(‘WP_SITEURL’, ”);
保存,OK了!但是这种修改方式是只能用户网网站根目录,并且使用默认的80端口
如果你不是用网站的根目录,或者用非80端口,那就用第二种方法
2.打开wp-includes/post.php文件,修改函数wp_get_attachment_url(3.7.1在4276行)为如下代码
function wp_get_attachment_url( $post_id = 0 ) {
$file_dir=dirname(__FILE__);
$server_root=$_SERVER[DOCUMENT_ROOT];
$file_dir=substr($file_dir,strlen($server_root));
$file_dir=substr($file_dir,0,-12);
if($file_dir!=”){
$file_dir=’/’.substr($file_dir,1);
}
$post_id = (int) $post_id;
if ( !$post =& get_post( $post_id ) )
return false;
$url = ”;
if ( $file = get_post_meta( $post->ID, ‘_wp_attached_file’, true) ) { //Get attached file
if ( ($uploads = wp_upload_dir()) && false === $uploads[‘error‘] ) { //Get upload directory
if ( 0 === strpos($file, $uploads[‘basedir‘]) ) //Check that the upload base exists in the file location
//$url = str_replace($uploads[‘basedir‘], $uploads[‘baseurl‘], $file); //replace file location with url location
$url=$file_dir.”/wp-content/uploads/”.$file;
elseif ( false !== strpos($file, ‘wp-content/uploads’) )
//$url = $uploads[‘baseurl‘] . substr( $file, strpos($file, ‘wp-content/uploads’) + 18 );
$url=$file_dir.”/wp-content/uploads/”.$file;
else
//$url = $uploads[‘baseurl‘] . “/$file”; //Its a newly uploaded file, therefor $file is relative to the basedir.
$url=$file_dir.”/wp-content/uploads/”.$file;
}
}
if ( empty($url) ) //If any of the above options failed, Fallback on the GUID as used pre-2.7, not recomended to rely upon this.
$url = get_the_guid( $post->ID );
if ( ‘attachment’ != $post->post_type || empty($url) )
return false;
return apply_filters( ‘wp_get_attachment_url’, $url, $post->ID );
}
保存,OK了
这样你以后写的文章日志里面的多媒体文件路径都是用相对路径了,更换域名空间之后图片地址不会失效!
