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:

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');

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

function the_url( $url ) {
    return get_bloginfo( 'url' );
}
add_filter( 'login_headerurl', 'the_url' );

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:

// custom login for theme
function childtheme_custom_login() {
	echo '';
}

add_action('login_head', 'childtheme_custom_login');

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:

.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 .forgetmenot {

}

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

.login form .input {
