WPINC is not defined. Plugin causes white screen.

[dac514]

The first 3 lines of this plugin do:

if ( ! defined( 'WPINC' ) ) {
    die;
}

If you look at the WordPress Code you can see that WPINC is maybe defined in the 3rd condition. We are setup using https://roots.io/bedrock/ and this plugin is autoloaded using Composer, therefore WPINC is never defined and die causes a "white screen of death"

Please use ABSPATH instead.

WPINC is defined in wp-settings.php and should be called in any standard WP installation.

https://github.com/WordPress/wordpress-develop/blob/8f95800d52c1736d651ae6e259f90ad4a0db2c3f/src/wp-settings.php#L16

Besides, this is simply to prevent the file from being called directly.

Becauase the plugin is loaded using Composer Autoload, because we use Bedrock, because of the reasons above... WPINC is not always defined.

ABSPATH does the same thing.

You have a number of moving pieces present.

Having a file make use of Composer’s autoloader does not call the file directly, it allows the class to be autoloaded if/when someone calls the class eliminating the need for a require or include command.

I confess I no nothing of Bedrock, but I do know that in the usual manner of running WordPress the wp-settings.php file is called and WPINC is defined.

All this said, I don’t have a strong feeling one way or another and I’ll wait for @collizo4sky to weigh in, but my gut tells me something in Bedrock is loading WP without the wp-settings.php file.

Bedrock might not be standard, but it is best practices for web development IMHO. The issue is that the bootstrapping starts here:

https://github.com/roots/bedrock/blob/master/web/wp-config.php

This plugin, being Composer compatible (2018, yay!), will get initialized by `vendor/autoload.php' before wp-settings.php is called.

Thank you for your consideration.

@afragen I'm going to open an issue on Bedrock. I looked at your plugins. The GitHub one uses this convention as well. From what you say, seems like this convention is common and maybe this is a Bedrock issue. Thanks for the info.

Fixed. https://github.com/collizo4sky/persist-admin-notices-dismissal/commit/067589be4c0b9dfa221320dfb15f9752269c3c82

composer update :wink:

I had this issue in my ProfilePress plugin. I had to fix it by adding this line define( 'WPINC', true );

I just need to update the code to define( 'ABSPATH', true ); because ABSPATH is not defined in my custom bootstrap process.

Thanks @afragen for the fix for bedrock users
