按帖子而不是按日期将图像保存在文件夹中

Question

我在本地使用 WordPress，试图完成一个带有自定义帖子的小型上传程序。

媒体文件自动保存在文件夹中按年和月。

我该怎么做才能将图片保存在文件夹中按帖子标题？

Answer 1

您可以使用两种方式。

使用插件获取按标题保存的图片
上传图片时使用图片标签

Answer 2

function save_attachment_meta($post_id, $post, $update){
    global $wpdb;
    $currentDateTime = date("Y-m-d H:i:s");
    // First check if the file appears on the _FILES array

按帖子而不是按日期将图像保存在文件夹中

save images in folders by posts, not by dates

php

media

wordpress

image
