PHP notice "WP_CONTENT_DIR undefined" occurs when creating wp-config.php

[lilyfan]

The first step of installing: wordpress can create a wp-config.php file with setup-config.php.
In this step, WP_CONTENT_DIR is not defined. But wp-includes/functions.php does not cosider the situation.
So, a PHP notice occures:
Use of undefined constant WP_CONTENT_DIR - assumed 'WP_CONTENT_DIR' in /home/*/public_html/wp-includes/functions.php on line 1988

To solve the problem: change line 1988 of wp-includes/fuctions.php below:
if (defined('WP_CONTENT_DIR') && file_exists( WP_CONTENT_DIR . '/db.php' ) )

To solve the problem: change line 1988 of wp-includes/fuctions.php below: if(defined('WP_CONTENT_DIR') && file_exists( WP_CONTENT_DIR . '/db.php' ) )

Only problem with that, Is that to install, it means the user *must* use mysql/default database.

A better solution would be for the install script to define the new definitions at a best-guess i think.

DD32 is probably right about defining a best guess at that early stage, either that or skip that part during install. I'll look into it.

Patch defines WP_CONTENT_DIR at the start of setup-config.php along with the others. That should fix it.

(In [8238]) Define WP_CONTENT_DIR in setup-config.php. Props sambauers. fixes #7221
