常用函数-wp_insert_post()

常用函数-wp_insert_post()

说明

该函数可在数据库中插入文章（及页面）。它可以进行处理变量，检查操作，填充日期/时间等缺失变量等工作。该函数以对象作为变量，返回已创建文章的编号（出错时返回0）。

用法

<?php wp_insert_post( $post ); ?>

示例

调用wp_insert_post（）前需创建对象以传递组成文章的必要元素。wp_insert_post（）可自动填写默认表格，但用户需提供文章标题和内容，否则数据库写入不成功。

用户可在数据库中简单定义新关键字，之后就可以添加更多文章要素。关键字应与数据库wp_posts表格中纵列名称相匹配。

// Create post object    
  $my_post = array();    
  $my_post['post_title'] = 'My post';    
  $my_post['post_content'] = 'This is my post.';    
  $my_post['post_status'] = 'publish';    
  $my_post['post_author'] = 1;    
  $my_post['post_category'] = array(8,39);    

// Insert the post into the database    
  wp_insert_post( $my_post );  

上面提到的默认表格在函数主体中有所定义。定义如下：

$defaults = array(    
  'post_status' => 'draft',    
  'post_type' => 'post',    
  'post_author' => $user_ID,    
  'ping_status' => get_option('default_ping_status'),    
  'post_parent' => 0,    
  'menu_order' => 0,    
  'to_ping' =>  '',    
  'pinged' => '',    
  'post_password' => '',    
  'guid' => '',    
  'post_content_filtered' => '',   
  'post_excerpt' => ''  
);  

类别

需要将类别作为整数数组传递，该数组应与数据库中的类别编号相匹配。即使文章只属于某一项类别，情况也应如此。

参数

$post

（对象）（必需）能表示可组成文章元素的对象。这些元素与数据库wp_posts表格中的纵列名称应一一对应。

默认值：空

文章数组的内容可取决于用户的默认值的信赖程度。下表列出了用户可为文章设置的所有选项：

$post = array(    
  'comment_status' => [ 'closed' | 'open' ] // 'closed' means no comments.    
  'ID' => [ <post id> ] //Are you updating an existing post?    
  'menu_order' => [ <order> ] //If new post is a page, sets the order should it appear in the tabs.    
  'page_template => [ <template file> ] //Sets the template for the page.    
  'ping_status' => [ ? ] //Ping status?    
  'pinged' => [ ? ] //?    
  'post_author' => [ <user ID> ] //The user ID number of the author.    
  'post_category => [ array(<category id>, <...>) ] //Add some categories.    
  'post_content' => [ <the text of the post> ] //The full text of the post.    
  'post_date' => [ Y-m-d H:i:s ] //The time post was made.    
  'post_date_gmt' => [ Y-m-d H:i:s ] //The time post was made, in GMT.    
  'post_excerpt' => [ <an excerpt> ] //For all your post excerpt needs.    
  'post_parent' => [ <post ID> ] //Sets the parent of the new post.    
  'post_password' => [ ? ] //password for post?    
  'post_status' => [ 'draft' | 'publish' | 'pending' ] //Set the status of the new post.    
  'post_title' => [ <the title> ] //The title of your post.    
  'post_type' => [ 'post' | 'page' ] //Sometimes you want to post a page.    
  'tags_input' => [ '<tag>, <tag>, <...>' ] //For tags.    
  'to_ping' => [ ? ] //?  
);    

返回的值

若文章成功加入数据库，返回文章编号。否则返回0.
