WordPress / PHP - 如何将变量移动到非wordpress文件？

When I execute this code in functions.php I get the path:

$upload_dir = wp_upload_dir();
echo $upload_dir['path'];

//Returns: /some/correct/path/

But I want this path to be moved to my custom script located in uploads.php where I can't execute wp_upload_dir();. I obviously can't include() functions.php either because it would execute everything else that is located there.

Is there any tricky way to pass $upload_dir variable to uploads.php?

You just need to load wp-load.php it will give you access to all wordpress functions, just do something like this:

<?php
   require( '../wordpress_install_root/wp-load.php' );
   $upload_dir = wp_upload_dir();
   echo $upload_dir['path'];
?>

This is an easy way.

just include the following at the top of your external php file:

$wp_url = str_replace('wp-content/plugins/YOUR_PLUGIN_NAME/includes', "", dirname(__FILE__));
include_once($wp_url . 'wp-load.php');

obviously replace YOUR_PLUGIN_NAME with the name of your plugin. I use it in a single file that is being called by Paypal and other payment gateways.

Some also use the following but i never got it to work properly and I'm unsure if it is deprecated.

require_once('../../../../wp-blog-header.php');
