wp eval

Executes arbitrary PHP code.

This command runs on the before_wp_load hook, just before the WP load process begins.

Note: because code is executed within a method, global variables need to be explicitly globalized.

OPTIONS

See the argument syntax reference for a detailed explanation of the syntax conventions used.

<php-code>

The code to execute, as a string.

[--skip-wordpress]

Execute code without loading WordPress.

[--hook=<hook>]

Execute code after a specific WordPress hook has fired.

EXAMPLES

# Display WordPress content directory.
$ wp eval 'echo WP_CONTENT_DIR;'
/var/www/wordpress/wp-content

# Generate a random number.
$ wp eval 'echo rand();' --skip-wordpress
479620423

# Execute code after WordPress is fully loaded.
$ wp eval 'echo "Current user: " . wp_get_current_user()->user_login;' --hook=wp_loaded
Current user: admin
