WordPress 快速添加友情链接的另类方法

首先将下面的代码复制到当前主题的 functions.php 文件中,或者单独作为一个插件激活。

<?php
/*
Plugin Name: WPJAM Blogroll
Plugin URI: http://blog.wpjam.com/m/wpjam-blogroll/
Description: 快速添加友情链接
Version: 0.1
Author: Denis
Author URI: http://blog.wpjam.com/
*/
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。
最后在主题输出友情链接的地方通过下面的模板函数调用:

<?php wpjam_blogroll();?>
