WordPress Sentry (wp-sentry)

A (unofficial) WordPress plugin to report PHP and JavaScript errors to Sentry.

What?

This plugin can report PHP errors (optionally) and JavaScript errors (optionally) to Sentry and integrates with its release tracking.

It will auto detect authenticated users and add context where possible. All context/tags can be adjusted using filters mentioned below.

Usage

1. Install this plugin by cloning or copying this repository to your wp-contents/plugins folder
2. Configure your DSN as explained below
3. Activate the plugin through the WordPress admin interface

Note: this plugin does not do anything by default and has no admin interface. A DSN must be configured first.

Configuration

(Optionally) track PHP errors by adding this snippet to your wp-config.php and replace DSN with your actual DSN that you find in Sentry:

define( 'WP_SENTRY_DSN', 'DSN' );

Note: Do not set this constant to disable the PHP tracker.

---

(Optionally) set the error types the PHP tracker will track:

define( 'WP_SENTRY_ERROR_TYPES', E_ALL & ~E_DEPRECATED & ~E_NOTICE & ~E_USER_DEPRECATED );

---

(Optionally) track JavaScript errors by adding this snippet to your wp-config.php and replace PUBLIC_DSN with your actual public DSN that you find in Sentry (never use your private DSN):

define( 'WP_SENTRY_PUBLIC_DSN', 'PUBLIC_DSN' );

Note: Do not set this constant to disable the JavaScript tracker.

---

(Optionally) define a version of your site; by default the theme version will be used. This is used for tracking at which version of your site the error occurred. When combined with release tracking this is a very powerful feature.

define( 'WP_SENTRY_VERSION', 'v2.0.13' );

(Optionally) define an environment of your site. Defaults to unspecified.

define( 'WP_SENTRY_ENV', 'production' );

Filters

This plugin provides the following filters to plugin/theme developers.

Please note that some filters are fired when the Sentry trackers are initialized so they won't fire if you define them in you theme or in a plugin that loads after WP Sentry does.

Common to PHP & JavaScript trackers

wp_sentry_user_context (array)

You can use this filter to extend the Sentry user context for both PHP and JS trackers.

WARNING: These values are exposed to the public in the JS tracker, so make sure you do not expose anything private!

Example usage:

/**
 * Customize sentry user context.
 *
 * @param array $user The current sentry user context.
 *
 * @return array
 */
function customize_sentry_user_context( array $user ) {
    return array_merge( $user, array(
        'a-custom-user-meta-key' => 'custom value',
    ));
}
add_filter( 'wp_sentry_user_context', 'customize_sentry_user_context' );

Note: This filter fires on the WordPress set_current_user action.

Specific to PHP tracker:

wp_sentry_dsn (string)

You can use this filter to override the Sentry DSN used for the PHP tracker.

Example usage:

/**
 * Customize sentry dsn.
 *
 * @param string $dsn The current sentry public dsn.
 *
 * @return string
 */
function customize_sentry_dsn( $dsn ) {
    return 'https://<key>:<secret>@sentry.io/<project>';
}
add_filter( 'wp_sentry_dsn', 'customize_sentry_dsn' );

Note: This filter fires on when WP Sentry initializes and after the WP after_setup_theme.

---

wp_sentry_options (array)

You can use this filter to customize the Sentry options used to initialize the PHP tracker.

Example usage:

/**
 * Customize sentry options.
 *
 * @param array $options The current sentry options.
 *
 * @return array
 */
function customize_sentry_options( array $options ) {
    return array_merge( $options, array(
        'tags' => array(
            'my-custom-tag' => 'custom value',
        ),
    ));
}
add_filter( 'wp_sentry_options', 'customize_sentry_options' );

Note: This filter fires on when WP Sentry initializes and after the WP after_setup_theme.

---

wp_sentry_send_data (array|bool)

Provide a function which will be called before Sentry PHP tracker sends any data, allowing you both to mutate that data, as well as prevent it from being sent to the server.

Example usage:

/**
 * Customize sentry send data.
 *
 * @param array $data The sentry send data.
 *
 * @return array|bool Return the data array or false to cancel the send operation.
 */
function filter_sentry_send_data( array $data ) {
    $data['tags']['my_custom_key'] = 'my_custom_value';

    return $data;
}
add_filter( 'wp_sentry_send_data', 'filter_sentry_send_data' );

Note: This filter fires whenever the Sentry SDK is sending data to the Sentry server.

Specific to JS tracker

wp_sentry_public_dsn (string)

You can use this filter to override the Sentry DSN used for the JS tracker.

WARNING: This value is exposed to the public, so make sure you do not use your private DSN!

Example usage:

/**
 * Customize public sentry dsn.
 *
 * @param string $dsn The current sentry public dsn.
 *
 * @return string
 */
function customize_public_sentry_dsn( $dsn ) {
    return 'https://<key>@sentry.io/<project>';
}
add_filter( 'wp_sentry_public_dsn', 'customize_public_sentry_dsn' );

---

wp_sentry_public_options (array)

You can use this filter to customize/override the sentry options used to initialize the JS tracker.

WARNING: These values are exposed to the public, so make sure you do not expose anything private !

Example usage:

/**
 * Customize public sentry options.
 *
 * @param array $options The current sentry public options.
 *
 * @return array
 */
function customize_public_sentry_options( array $options ) {
    return array_merge( $options, array(
        'tags' => array(
            'custom-tag' => 'custom value',
        ),
    ));
}
add_filter( 'wp_sentry_public_options', 'customize_sentry_public_options' );
