I am having issues when adding a custom cli command into an existing wordpress theme. When I run wp --info I get the following:

PHP binary: /usr/local/Cellar/php70/7.0.13_6/bin/php
PHP version:    7.0.13
php.ini used:   /usr/local/etc/php/7.0/php.ini
WP-CLI root dir:    phar://wp-cli.phar
WP-CLI packages dir:    
WP-CLI global config:   
WP-CLI project config:  /Users/julie/isl-site/isl-site/wp-cli.yml
WP-CLI version: 1.0.0

However, when I register the example command within my theme/functions.php

function foo_command( $args ) {
WP_CLI::success( $args[0] );
}
WP_CLI::add_command( 'foo', 'foo_command' );

I get the following errors:

Uncaught Error: Class 'WP_CLI' not found in /my-site/public/wp-content/themes/my-theme/lib/theme-functions.php:278

• I guess my question is where exactly I need to put the code for WP_CLI::add_command() as I thought I could just put it in a file (in this case theme-wp-cli-commands.php) within the theme. – Julie Commented Jan 17, 2017 at 19:16
• Thanks for your prompt responses @RobBenz I am just learning wpi-cli. I did as you suggested and added the following to my functions.php please see the updated question. I think it has to do with my wp-config.php file – Julie Commented Jan 17, 2017 at 19:59
• to the best of my knowledge you do not use wp-cli with a theme. it is more of a platform to manage your wordpress install entirely. what exactly is the command you are trying to register. – RobBenz Commented Jan 17, 2017 at 20:58
• you could try adding the command you are trying to register to wp-cli.yml file – RobBenz Commented Jan 17, 2017 at 21:06

You'll need to wrap your statement within a class_exists() check:

function foo_command( $args ) {
    WP_CLI::success( $args[0] );
}
if ( class_exists( 'WP_CLI' ) ) {
    WP_CLI::add_command( 'foo', 'foo_command' );
}

This way, the command is only registered when the WP_CLI class exists — because the WP_CLI class will only exist when WP-CLI is running.

You can check if WP_CLI is defined e.g.

function foo_command( $args ) {
    WP_CLI::success( $args[0] );
}
if ( defined('WP_CLI') && true === constant('WP_CLI') ) {
    WP_CLI::add_command( 'foo', 'foo_command' );
}
