Environment File Editor

Environment File Editor

The Environment File Editor lets you view and modify your site’s environment configuration file directly from the FlyWP dashboard — no SSH access required.

What Are Environment Variables

Environment variables are key-value pairs that control how your application behaves at runtime. They are stored in a file on the server and read by WordPress and any plugins or themes that support them.

Common uses include:

• Setting API keys or secret tokens required by plugins
• Defining service endpoints that differ between staging and production
• Enabling or disabling debug modes without touching code
• Passing credentials to third-party integrations

Tip

Most WordPress configuration — database connection, table prefix, debug flags, salts — is better managed through the WP Config Editor. Use the Environment File Editor specifically for non-standard environment variables that your plugins or custom code require via getenv() or $_ENV.

Opening the Editor

1. Open your site from the FlyWP dashboard.
2. Click the Environment tab in the site navigation.

The editor loads the current contents of your site’s environment file from the server and displays them in a syntax-highlighted code editor.

Editing and Saving

Make your changes directly in the editor. Each variable follows the format:

VARIABLE_NAME=value

When you are done, click Save to write the changes back to the server. FlyWP sends the updated file to your server and applies it immediately — no restart is needed for the file itself, though some applications may require a PHP or Docker restart to pick up new values.

Editing the environment file incorrectly can break your site. A syntax error, a missing value, or an incorrect credential can cause plugin failures or a white screen. Before making significant changes, note the current values so you can restore them if needed.

Common Environment Variables

Variable	Description
APP_ENV	Application environment (production, staging, development)
APP_DEBUG	Enable verbose error output (true or false)
STRIPE_KEY	Public key for Stripe payment integration
STRIPE_SECRET	Secret key for Stripe payment integration
MAILGUN_SECRET	API key for Mailgun email delivery
AWS_ACCESS_KEY_ID	AWS credentials for S3 or other AWS services

The variables available depend entirely on which plugins and themes your site uses. Refer to your plugin’s documentation for the variable names it expects.
