很多企业网站的左下方都有一个下拉的友情链接，这个该怎么实现呢？其实很简单，在主题的function.php文件中添加以下代码：

`

function dropdown_links(){

global $wpdb;

$sql = “SELECT link_url, link_name, link_description FROM $wpdb->links WHERE link_visible = ‘Y’ Order By link_name”;

$results = $wpdb->get_results($sql);

if (!$results) {

return; }

$output =’

Select … ‘;

foreach ($results as $row) {

$the_link = ‘#’;

if (!empty($row->link_url)){

$the_link = wp_specialchars($row->link_url);

}

$desc = wp_specialchars($row->link_description, ENT_QUOTES);

$name = wp_specialchars($row->link_name, ENT_QUOTES);

$title = $desc;

if (‘’ != $title) {

$title = ‘ title=”‘ . $title . ‘“‘;

}

$alt = ‘ alt=”‘ . $name . ‘“‘;

$output .= ‘’.$name.’’;

}

$output .= ‘

‘;

echo $output;

}

`

然后在使用下拉友情链接的地方 添加 ``即可，css样式你可以按照自己的爱好来自行定义，OK ！！
