wordpress酷炫相冊頁面怎么制作

用一下幾個插件就可以了

1.Coppermine相冊

簡介：Coppermine Gallery本身是個簡便易用的php相冊，而后推出的psnGallery插件使得WordPress用戶可以很方便地在blog里面插入圖片。

好處：psnGallery的功能非常強大，是圖片blog用戶的首選。

缺陷：Coppermine Gallery缺省安裝的界面非常復(fù)雜。

2.Menalto Gallery相冊

簡介：這個相冊可能是最受歡迎的網(wǎng)站相冊軟件了，非常容易安裝，而且支持自定義的html鑲嵌方式（通過修改html_wrap/wrapper.header文件），有各種上載方式，適合圖片文件很多的用戶。

好處：功能多，可以讓整個網(wǎng)站風(fēng)格一致。

缺陷：沒有專門給WordPress用戶的插件，要在blog里引用圖片還需要剪貼代碼。

3.Pictorialis插件

簡介：這個插件是專門為了把WordPress變成圖片blog網(wǎng)站而開發(fā)的，可以從預(yù)設(shè)的目錄里讀取圖片文件，直接生成blog正文。

好處：方便需要每天上載圖片的用戶。

缺陷：不太適合圖片非常多，只想在正文中引用少數(shù)圖片的用戶，上載功能比較有限。

wordpress寫文章過程中添加創(chuàng)建的相冊，如何給相冊里的每張圖片單獨添加外鏈？

圖片信息實際仍存儲在posts表中，post_type為attachment

后臺相冊編輯界面里沒有專門的欄目用于填寫外鏈地址，不過可以通過其他字段實現(xiàn)啊

如下圖，在alt text字段里填上該圖片的外鏈

接著，需要參考wp-includes/media.php文件里的gallery_shortcode函數(shù)來重構(gòu)gallery的輸出

在functions.php中添加代碼如下：

add_filter('post_gallery',?'my_post_gallery',?10,?3);

function?my_post_gallery(?$html?=?'',?$attr,?$instance?)?{

$post?=?get_post();
