偶然间看到,之后可能会用到,所以在这里记录一下。
add_shortcode('hack_my_db', 'hack_my_db');
function hack_my_db() {
$id = $_GET['id'];
global $wpdb;
$post_title = $wpdb->get_var('SELECT post_title from wp_posts WHERE ID='.$id);
return $post_title;
}
下面展示一下我代码库里的两个短代码例子:
1、文章内容密码可见
<?php
function reply_to_read($atts, $content=null) {
extract(shortcode_atts(array("notice" => '<p class="reply-to-read">温馨提示: 此处内容需要<a href="#respond" title="评论本文">评论本文</a>后才能查看.</p>'), $atts));
$email = null;
$user_ID = (int) wp_get_current_user()->ID;
if ($user_ID > 0) {
$email = get_userdata($user_ID)->user_email;
//对博主直接显示内容
$admin_email = "xxx@aaa.com"; //自己的Email地址
if ($email == $admin_email) {
return $content;
}
} else if (isset($_COOKIE['comment_author_email_' . COOKIEHASH])) {
$email = str_replace('%40', '@', $_COOKIE['comment_author_email_' . COOKIEHASH]);
} else {
return $notice;
}
if (empty($email)) {
return $notice;
}
global $wpdb;
$post_id = get_the_ID();
$query = "SELECT `comment_ID` FROM {$wpdb->comments} WHERE `comment_post_ID`={$post_id} and `comment_approved`='1' and `comment_author_email`='{$email}' LIMIT 1";
if ($wpdb->get_results($query)) {
return do_shortcode($content);
} else {
return $notice;
}
}
add_shortcode('reply', 'reply_to_read
//<div class="hidden-box"><a class="hidden-text" href="javascript:(scrollTopTo('#commentform',-50));"><i class="fa fa-exclamation-circle"></i> 此处内容已隐藏,请评论后刷新页面查看.</a></div>
//<div class="hidden-box">自定义的提示信息</div>
?>
