【WordPress】WordPress标签大全—Michael王朝

（需要配合后台菜单设置）

wp_nav_menu( array( ‘theme_location’ => ‘top-links’, ‘container_id’ => ‘topLinks’, ‘fallback_cb’=>’toplinks’) );

}else{

toplinks();

}?>

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 target=”_blank” 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

<ul>

<?php

//通过get_posts函数，根据分类ID来获取这个ID下的文章内容。
