WordPress圖片地址在預設編輯下是使用額絕對路徑，這樣別人複製你文章到其他的網站上，圖片也可以正常顯示，但是如果我想更改部落格的域名，或者路徑，那麼這些圖片的地址全部失效，不能正常顯示。優搜網在網上找到兩種解決Wordpress模板圖片使用相對路徑的方法，希望可以幫到大家。
1.修改Wordpress主題根目錄下的wp-config.php，這個檔案只有在安裝好Wordpress之後才會出現，在該檔案中加入一下兩行
|
1 2 |
define(‘WP_HOME’, ”); define(‘WP_SITEURL’, ”); |
儲存，OK了！但是這種修改方式是隻能使用者網網站根目錄，並且使用預設的80埠
如果你不是用網站的根目錄，或者用非80埠，那就用第二種方法
2.開啟wp-includes/post.php檔案，修改函式wp_get_attachment_url（3.7.1在4276行）為如下程式碼

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 |
