WordPress快速添加友情链接

WordPress 3.5 默认隐藏了友情链接管理功能，虽然可以 恢复链接管理功能 ，但是自带的链接管理仍旧太复杂， 下面分享下 @我爱水煮鱼  的方法。

将下面的代码添加到当前主题的 functions.php 文件中，或者另存为单独的php文件，上传到插件目录激活：

add_action('admin_init', 'wpjam_blogroll_settings_api_init');

}
 
function wpjam_blogroll(){
    $wpjam_blogroll_setting =  get_option('wpjam_blogroll_setting');
    if($wpjam_blogroll_setting){
        $wpjam_blogrolls = explode("\n", $wpjam_blogroll_setting);
        foreach ($wpjam_blogrolls as $wpjam_blogroll) {
            $wpjam_blogroll = explode("|", $wpjam_blogroll );
            echo ' | <a href="'.trim($wpjam_blogroll[0]).'" title="'.esc_attr(trim($wpjam_blogroll[1])).'">'.trim($wpjam_blogroll[1]).'</a>';
        }
    }
}

add_action(‘admin_init’, ‘wpjam_blogroll_settings_api_init’);
function wpjam_blogroll_settings_api_init() {
add_settings_field(‘wpjam_blogroll_setting’, ‘友情链接’, ‘wpjam_blogroll_setting_callback_function’, ‘reading’);
register_setting(‘reading’,’wpjam_blogroll_setting’);
}
function wpjam_blogroll_setting_callback_function() {
echo ‘<textarea name="wpjam_blogroll_setting" rows="10" cols="50" id="wpjam_blogroll_setting" class="large-text code">’ . get_option(‘wpjam_blogroll_setting’) . ‘</textarea>’;
} function wpjam_blogroll(){
$wpjam_blogroll_setting = get_option(‘wpjam_blogroll_setting’);
if($wpjam_blogroll_setting){
$wpjam_blogrolls = explode("\n", $wpjam_blogroll_setting);
foreach ($wpjam_blogrolls as $wpjam_blogroll) {
$wpjam_blogroll = explode("|", $wpjam_blogroll );
echo ‘ | <a href="’.trim($wpjam_blogroll[0]).’" title="’.esc_attr(trim($wpjam_blogroll[1])).’">’.trim($wpjam_blogroll[1]).'</a>’;
}
}
} ?>

然后就可以在 WordPress 后台 > 设置 > 阅读 界面，就有一个友情链接添加的输入框。按照 链接 |标题 的方式输入所有的友情链接：

最后在需要显示友情链接的模板文件的适当位置，使用下面的代码进行调用：

1

<?php if (function_exists(wpjam_blogroll)) wpjam_blogroll();?>

<?php if (function_exists(wpjam_blogroll)) wpjam_blogroll();?>

1.新窗口打开链接

新窗口打开，修改最上面的代码的26行为：

1

echo ' | <a target="_blank" href="'.trim($wpjam_blogroll[0]).'" title="'.esc_attr(trim($wpjam_blogroll[1])).'">'.trim($wpjam_blogroll[1]).'</a>';

echo ‘ | <a target="_blank" href="’.trim($wpjam_blogroll[0]).’" title="’.esc_attr(trim($wpjam_blogroll[1])).’">’.trim($wpjam_blogroll[1]).'</a>’;

2.只在首页显示

首页要看你具体添加到哪个文件了，你可以通过下面的代码调用试试：

1

<?php if (function_exists(wpjam_blogroll) && (is_home()||is_front_page()) wpjam_blogroll();?>

<?php if (function_exists(wpjam_blogroll) && (is_home()||is_front_page()) wpjam_blogroll();?>
