README

A phpcs sniff to disallow using get_current_user().

Particularly when using a PHP framework like WordPress, it's very unlikely that most code will want to use the PHP function get_current_user(). It can also easily be confused with other framework functions like WordPress's wp_get_current_user(). This sniff makes using the function an error, although legitimate uses can still be made if the sniff is disabled for specific lines.

Installation

To use these rules in a project which is set up using composer, we recommend using the phpcodesniffer-composer-installer library which will automatically use all installed standards in the current project with the composer type phpcodesniffer-standard when you run phpcs.

composer require --dev squizlabs/php_codesniffer dealerdirect/phpcodesniffer-composer-installer
composer require --dev sirbrillig/phpcs-no-get-current-user

Configuration

When installing sniff standards in a project, you edit a phpcs.xml file with the rule tag inside the ruleset tag. The ref attribute of that tag should specify a standard, category, sniff, or error code to enable. It’s also possible to use these tags to disable or modify certain rules. The official annotated file explains how to do this.

<?xml version="1.0"?>
<ruleset name="MyStandard">
 <description>My library.</description>
 <rule ref="NoGetCurrentUser"/>
</ruleset>

Sniff Codes

There is one sniff code that is reported by this sniff.

• NoGetCurrentUser.Disallowed.NoGetCurrentUser.Found

In any given file, you can use phpcs comments to disable these sniffs. For example:

$php_user = get_current_user(); // phpcs:ignore NoGetCurrentUser.Disallowed.NoGetCurrentUser.Found

For a whole file, you can ignore a sniff like this:

<?php
// phpcs:disable NoGetCurrentUser.Disallowed.NoGetCurrentUser.Found

Usage

Most editors have a phpcs plugin available, but you can also run phpcs manually. To run phpcs on a file in your project, just use the command-line as follows (the -s causes the sniff code to be shown, which is very important for learning about an error).

vendor/bin/phpcs -s src/MyProject/MyClass.php
