#9166 closed feature request (wontfix)

Installer should check that required constants are defined

Beside the fact, that you can come more or less often to the point to start a flame-war because WordPress is designed to have the static configuration settings in a PHP File, some things can be done to improve the installation-easyness and provide better hints to this error-prone way of setting something up.

For Example: WordPress does not verify that really needed config PHP-Constants _are_ defined. Let's assume a user does not understand the configuration and enters the following in wp-config.php

define('90a83383_dbYZ', 'putyourdbnamehere'); Der Name der Datenbank, die du benutzt.
define('90a83383_unZUF1', 'usernamehere');
Dein MySQL-Datenbank-Benutzername.
define('xxx', 'yourpasswordhere'); Dein MySQL-Passwort.

then the wordpress error message that the connection to the db server failed does not reflect the fact, that the constants DB_NAME, DB_USER or DB_PASSWORD are not defined. Putting out this message clearly, that wp-config.php is not properly configured and the database configuration should be checked would help much instead.

Maybe #6631 is of interest as well to improve the installing experience.

The compontent that use such constants should throw the error in case they need them obligatory.

suggesting wontfix on this. I mean, if a user can't create a wp-config file, he should use fantastico to install his site, or get hosted on wordpress.com

comment:6 DD325 years ago

Except that WordPress offers to create the wp-config.php file, which makes that arguement completely null.

A short message along the lines of (with better grammer of course) after including wp-config.php could possibly solve a few peopel getting confused.. But.. Hopefully theres enough documentation in the sample file already to explain it.

if ( ! defined('DB_PASS') )
die('wp-config is not configured properly. Please check the config defines');

First patch. What I do not like is the fact that this code will be executed with every request. So maybe such code should be placed in the wp-config-sample file with a comment that it can be removed if everything works.

that will prevent that it is executed on setups that use the installer as DD32 pointed out.

comment:15 ryan5 years ago

Is this much of a problem in practice? Regardless, I'd rather have a separate diagnostics tool. "Having a problem? Run this tool to see what's wrong." That way we're not doing these checks on every page load.

I don't thinks so... my own opinion above:
