Debugging

By default NADA does not show any errors, warnings. use these settings to enable debug mode to see the errors written to a log file or displayed on the page.

Enable error display

To show errors on the page (not recommended for production environments), edit index.php file in the nada root folder and change the environment from production to development.

Look for this line:

define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'production');

and change the value to development:

define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');

In development mode all PHP warnings and errors will be displayed on the page.

Enable error logging

To enable error logging, edit the file application/config/config.php and look for error_threshold. The default value is set to 0, change that to 1 to enable error logging.

The files are written to the folder logs, make sure the folder is writable by the webserver. For any PHP or database errors, you will see log files in the logs folder.

Enable database debugging

For debugging database related issues, you can enable database debugging by editing the application/config/database.php file and change the value for the config option db_debug to TRUE to see database errors displayed on the page.

Fixing composer dependencies

NADA uses Composer (package manager) for using third party libraries. The source code includes all vendor libraries and there is no need to manually install/update any libraries. However, if you see any errors related to vendor/autoload.php you can try solve them by updating the packages.

Download composer

#Download composer
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === '756890a4488ce9024fc62c56153228907f1545c228516cbf63f885e036d37e9a59d27d63f46af1d4d07ee0f76181c7d3') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

#update/install packages
php composer.phar install

Composer information

To learn more about composer, see https://getcomposer.org/ (opens new window)

If the commands fail to update the packages, you can try:

#remove the folder for vendor files
rm -rf vendor

#run composer to do a fresh install
rm composer.lock
php composer.phar install
