wordpress multisite settings synchronization articles

Idea: Create an API on another WordPress site, use cURL to simulate POST request API when publishing the article, and use the wp_insert_post() function to create the article. Supports synchronization of article titles, content, types, categories, and tags. Category synchronization requires that another site also creates a category with the same name. The alias and ID do not need to be the same.

Create a php file named post.php in the root directory of another site. The code is as follows:

//以下为代码正文…
<?php
//文章接收
define(&#39;WP_USE_THEMES&#39;, false);
require_once("wp-load.php");
$key=&#39;123456&#39;; //设置启动API的密钥
if($_POST[&#39;key&#39;]==$key){  
    $categorys=explode(&#39;,&#39;,$_POST[&#39;category&#39;]);  
    $category=array();  
    for($x=1;$x<count($categorys);$x++) {  
     $category[$x-1]=get_cat_ID($categorys[$x]);  
    }  
    $info = array(  
    &#39;post_title&#39; => $_POST[&#39;title&#39;],  
    &#39;post_content&#39; => $_POST[&#39;content&#39;],  
    &#39;post_status&#39; => &#39;publish&#39;,  
    &#39;post_author&#39; => 1, //发布文章的作者ID，1 为管理员  
    &#39;post_date&#39; => $_POST[&#39;date&#39;],  
    &#39;tags_input&#39; => $_POST[&#39;tags&#39;],  
    &#39;post_category&#39; => $category,  
    &#39;post_type&#39; => $_POST[&#39;type&#39;]  
    );  
    wp_insert_post( $info );  }

Then add it before the last ?> of the theme’s functions.php file The code has been downloaded, the key has been set, and the API address has been modified

//文章推送
add_action('publish_post', 'fanly_sync_post'); //钩子，在文章发布时执行  
function fanly_sync_post($post_ID) {  
    $key='www.exiang2.com'; //输入你设置的密钥  
    $url='http://www.domain.com/post.php';//API地址,就是接受数据的那个站点
    $post_info = get_post($post_ID);  
    if ( $post_info->post_status == 'publish' && $_POST['original_post_status'] != 'publish' ) {  
        $title=$_POST['post_title'];  
        $content=$_POST['content'];  
        $date=$_POST['aa'].'-'.$_POST['mm'].'-'.$_POST['jj'].' '.$_POST['hh'].':'.$_POST['mn'].':'.$_POST['ss'];  
        $category='';  
        for($x=1;$x<count($_POST[&#39;post_category&#39;]);$x++) {  
          $category.=&#39;,&#39;.get_cat_name($_POST[&#39;post_category&#39;][$x]);  
        }  
        $type=$_POST[&#39;post_type&#39;];  
        $tags=str_replace(&#39;、&#39;,&#39;,&#39;,$_POST[&#39;tax_input&#39;][&#39;post_tag&#39;]);  
        if($_POST[&#39;newtag&#39;][&#39;post_tag&#39;]){  
            $tags.=&#39;,&#39;.str_replace(&#39;、&#39;,&#39;,&#39;,$_POST[&#39;newtag&#39;][&#39;post_tag&#39;]);  
        }  
        $data = &#39;key=&#39;.$key.&#39;&title=&#39;.$title.&#39;&content=&#39;.$content.&#39;&date=&#39;.$date.&#39;&category=&#39;.$category.&#39;&type=&#39;.$type.&#39;&tags=&#39;.$tags;  
        $ch = curl_init (); //cURL模拟POST  
        curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, TRUE );  
        curl_setopt ( $ch, CURLOPT_POST, TRUE );  
        curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );  
        curl_setopt ( $ch, CURLOPT_URL, $url );  
        curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, FALSE);  
        $ret = curl_exec ( $ch );  
        curl_close ( $ch );  
        return $ret;  
   }  }
