wordpress技巧：改变登录logo及链接

诸位wordpress玩友们，是否想过改变你们的wordpress站点的登录logo及logo链接呢？，默认情况下：

1、使用wordpress.org的logo

2.这个logo的链接是http://wordpress.org/

对于要求比较严格的玩友们来说，这显然不能接受，可能会提出修改这个logo以及链接。怎么做呢？其实只需要两步，添加两个函数到functions.php内：

一、添加修改默认登录logo的函数：

[php]
function my_custom_login_logo() {
echo ‘<style type="text/css">
h1 a { background-image:url(‘.get_stylesheet_directory_uri().’/images/login.png) !important
; height: 120px !important; width: 410px !important; margin-left: -40px;}
</style>’;
}
add_action(‘login_head’, ‘my_custom_login_logo’);
[/php]

用photoshop（或你熟悉的图像软件）设计一个你喜欢的login.png图像，上传到主题文件夹下的images目录即可。height是高度，width是宽度。margin-left是左边距。

二、添加修改链接地址的函数

[php]
function the_url( $url ) {
return get_bloginfo( ‘url’ );
}
add_filter( ‘login_headerurl’, ‘the_url’ );
[/php]

这样就把你logo地址链接到了你的网站。

三、扩展

其实你除了修改这些，你还可以进一步修改登录框的样式，首先需要定义一下样式路径并添加一个样式文件到你的主题目录下：

[php]
<pre>// custom login for theme
function childtheme_custom_login() {
echo ‘<link rel="stylesheet" type="text/css" href="’ . get_bloginfo(‘stylesheet_directory’) . ‘/customlogin.css" />’;
}

add_action(‘login_head’, ‘childtheme_custom_login’);</pre>
[/php]

现在你可以添加样式到你的customlogin.css文件内，可以参照下面的样式修改：

[php]

.login, body.login {
background: url(‘.get_bloginfo(‘stylesheet_directory’) . ‘/images/login-bg.jpg) no-repeat fixed center top #222!important;
padding-top: 0 !important;
}

#login {

}

}

#login form p.submit {
margin-top: 10px;
}

.login form .input {
