如果要在posts表中插入内容，应create a new custom post type 第一一旦你有了一个自定义的帖子类型，你就可以通过几个修改来完成上面所做的事情。

<?php
function insert_post() {
    // Check to make sure your content exists.
    if ( ! isset( $_POST[\'text-post\'] ) || empty ( $_POST[\'text-post\'] ) ) {
        return false;
    }

    // Sanitizing user input is extremely important.
    $post_content = sanitize_textarea_field( $_POST[\'text-post\'] );
    // Used as an identifying string for this post. Not required.
    $hash = wp_hash( $post_content );

    // Build the insert post array.
    $post_arr = array(
        \'post_status\' => \'publish\',
        \'post_author\' => 1, // Set to the ID of author you want to associate this with.
        \'post_type\'   => \'your_custom_post_type\', // Change this to your custom post type slug.
        \'post_content\' => $post_content,
        // Not required. I like to store a hash of the content to make sure it\'s only posted once.
        \'meta_input\' => array(
            $hash => \'import_hash\',
        )
    );
    return wp_insert_post( $post_arr, true );
}
