wp db import backup.sql

This command imports the specified SQL file into your WordPress database. It’s crucial to ensure your database is properly backed up before performing imports to prevent data loss.

WP-CLI also offers options to customize exports and imports. For example, you can exclude specific tables or export only certain tables:

wp db export --exclude_tables=wp_options,wp_users
wp db export --tables=wp_posts,wp_postmeta

These commands provide flexibility in managing your database content, allowing for targeted backups or selective imports.

Running SQL Queries via WP-CLI

WP-CLI enables you to execute SQL queries directly from the command line, offering a powerful tool for database management and troubleshooting. The wp db query command allows you to run custom SQL statements:

wp db query "SELECT * FROM wp_users WHERE user_login = 'admin'"

This command retrieves all information for the user with the login “admin” from the wp_users table.

For more complex queries or multiple statements, you can use a SQL file:

wp db query < queries.sql

This command executes all SQL statements contained in the “queries.sql” file.

WP-CLI also provides options to format query results. For instance, you can output results in CSV format:

wp db query "SELECT ID, post_title FROM wp_posts WHERE post_type = 'post'" --format=csv

This command retrieves post IDs and titles, presenting the results in CSV format for easy analysis or import into spreadsheet software.

User Management Through WP-CLI

WP-CLI simplifies user management tasks in WordPress, allowing you to efficiently handle user-related operations from the command line. This powerful tool streamlines the process of creating, deleting, and modifying user accounts, saving time and reducing the risk of errors.

Creating and Deleting Users

WP-CLI offers straightforward commands for user management. To create a new user, use the wp user create command followed by the username and email address. For example:

wp user create johndoe johndoe@example.com --role=author

This command creates a user named “johndoe” with the email “johndoe@example.com” and assigns the role of author. You can specify additional parameters like --user_pass to set a custom password or --display_name to define the user’s display name.

To delete a user, employ the wp user delete command:

wp user delete 123

This removes the user with ID 123. Add the --reassign flag to transfer the deleted user’s content to another user:

wp user delete 123 --reassign=456

This command deletes user 123 and reassigns their content to user 456.

Resetting User Passwords

WP-CLI simplifies the process of resetting user passwords. To reset a password for a specific user, use the wp user update command:

wp user update 123 --user_pass=new_password

This updates the password for user 123 to “new_password”. For enhanced security, generate a random password:

wp user update 123 --user_pass=$(wp user generate-password)

This command creates a strong, random password for user 123. To reset passwords for multiple users simultaneously, utilize the wp user reset-password command:

wp user reset-password 123 456 789

This resets passwords for users with IDs 123, 456, and 789. Add the --send-email flag to automatically send password reset emails to the affected users:

wp user reset-password 123 456 789 --send-email

This ensures users receive their new login credentials securely via email.

Advanced WP-CLI Techniques

WP-CLI offers powerful capabilities for advanced WordPress management. These techniques allow you to extend functionality and streamline complex tasks.

Creating Custom WP-CLI Commands

Custom WP-CLI commands enhance your WordPress development workflow. To create a custom command:

1. Set up a plugin or theme directory
2. Create a PHP file for your command
3. Define a class extending WP_CLI_Command
4. Implement methods for subcommands
5. Register your command using WP_CLI::add_command()

Example custom command:

class Custom_CLI_Command extends WP_CLI_Command {
function hello( $args, $assoc_args ) {
WP_CLI::success( "Hello, WordPress!" );
}
}

WP_CLI::add_command( 'custom', 'Custom_CLI_Command' );

This creates a ‘wp custom hello’ command. Custom commands streamline site-specific tasks, automate repetitive processes, and extend WP-CLI’s functionality to suit your project’s needs.

Benefits of custom commands:

• Tailored functionality for your WordPress setup
• Improved development efficiency
• Consistent task execution across team members
• Simplified complex operations

Automating Tasks with WP-CLI Scripts

WP-CLI scripts automate complex WordPress management tasks. Create a shell script combining multiple WP-CLI commands to streamline your workflow.

Example script for site setup:

#!/bin/bash

# Install WordPress
wp core download
wp core config --dbname=mydb --dbuser=myuser --dbpass=mypassword
wp core install --url=example.com --title="My Site" --admin_user=admin --admin_password=password --admin_email=admin@example.com

# Install and activate plugins
wp plugin install wordpress-seo --activate
wp plugin install woocommerce --activate

# Set up theme
wp theme install twentytwentyone --activate

# Create pages
wp post create --post_type=page --post_title='About Us' --post_status=publish
wp post create --post_type=page --post_title='Contact' --post_status=publish

echo "Site setup complete!"

This script automates WordPress installation, plugin activation, theme setup, and page creation. WP-CLI scripts save time, reduce errors, and ensure consistent setups across multiple sites or environments.

Best Practices and Tips for Using WP-CLI

Mastering Command Structure

WP-CLI commands follow a consistent structure: wp [command] [subcommand] [options] [arguments]. Familiarize yourself with this pattern to efficiently navigate and utilize the tool. For example, wp plugin install contact-form-7 --activate installs and activates the Contact Form 7 plugin in one step.

Leveraging Tab Completion

Enable tab completion to speed up your workflow. It autocompletes command names, subcommands, and even plugin and theme names. To set it up, run wp cli completion --bash >> ~/.bash_profile for Bash or wp cli completion --zsh >> ~/.zshrc for Zsh.

Utilizing Global Parameters

Global parameters modify WP-CLI’s behavior across all commands. The --quiet flag suppresses informational messages, while --debug displays additional debugging information. Use --path=/path/to/wordpress to specify a custom WordPress installation directory.

Harnessing the Power of Filters

WP-CLI supports WordPress filters, allowing you to modify command behavior. For instance, to change the default number of posts displayed by wp post list, add this to your wp-config.php:

define( 'WP_CLI_FILTER_POSTS_PER_PAGE', 50 );

Creating Aliases for Complex Commands

Simplify frequently used complex commands with aliases. Add them to your ~/.wp-cli/config.yml file:

@staging:
ssh: user@staging.example.com
path: /path/to/wordpress

Run commands on your staging site with wp @staging plugin list.

Implementing Error Handling

Robust error handling improves script reliability. Use conditional statements and the WP_CLI::error() function to gracefully handle failures:

if ( ! $result ) {
WP_CLI::error( 'Operation failed.' );
}

Optimizing Performance with Bulk Operations

Perform bulk operations to save time. Instead of updating plugins one by one, use wp plugin update --all. Similarly, wp user create $(cat users.txt) creates multiple users from a file.

Leveraging Package Manager

Extend WP-CLI’s functionality with community packages. Install them using wp package install author/package-name. For example, wp package install wp-cli/doctor-command adds health check commands.

Maintaining Version Control

Keep your WP-CLI version up-to-date to access the latest features and bug fixes. Update it with wp cli update. Use wp cli check-update to check for available updates without installing them.
