wordpress检测当前页面百度是否收录

对于新上线网站总会去查询网页收录了多少，哪些还没收录。这个功能实用性极佳。打开文章直接显示网页是否被百度收录，没有收录可以直接点击提交给百度。

<pre>//百度收录提示
if(git_get_option('git_baidurecord_b') && function_exists('curl_init')):
function baidu_check($url) {
global $wpdb;
$post_id = (null === $post_id) ? get_the_ID() : $post_id;
$baidu_record = get_post_meta($post_id, 'baidu_record', true);
if ($baidu_record != 1) {
$url = 'http://www.baidu.com/s?wd=' . $url;
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$rs = curl_exec($curl);
curl_close($curl);
if (!strpos($rs, '没有找到')) {
if ($baidu_record == 0) {
update_post_meta($post_id, 'baidu_record', 1);
} else {
add_post_meta($post_id, 'baidu_record', 1, true);
}
return 1;
} else {
if ($baidu_record == false) {
add_post_meta($post_id, 'baidu_record', 0, true);
}
return 0;
}
} else {
return 1;
}
}
function baidu_record() {
if (baidu_check(get_permalink()) == 1) {
echo '<a title="" href="https://www.baidu.com/s?wd=' . get_the_title() . '" target="_blank"
rel="external nofollow" data-original-title="点击查看">已收录</a>';
} else {
echo '<a style="color: red;" title="" href="http://zhanzhang.baidu.com/sitesubmit/index?sitename=' . get_permalink() . '" target="_blank"
rel="external nofollow" data-original-title="点击提交，谢谢您!">未收录</a>';
}
}
endif;</pre>

上面的函数式放在functions文件中，然后在文章内容页面适合地方加入下方这段代码

<pre><?php
if (git_get_option('git_baidurecord_b') && function_exists('curl_init')) { ?><span class="muted"><i class="fa fa-flag"></i> <?php
baidu_record(); ?></span></pre>
