![]() This means that you cannot expect to fill your. It is very important to always remember that environment variables contained in your. ![]() Environment Variables as Replacements for Data When using the short prefix the property names must still exactly match the class defined name. ![]() You can use this file as a starting place for yourĪpplication by either renaming the template to. It has a large collection of variables your project might use that have been assignedĮmpty, dummy, or default values. Located at the project root named env (Notice there’s no dot (. There is a template file distributed with CodeIgniter that’s env to be at the root of your project alongside theĪpp directories. The term comes from the file name, which starts with a dot before the text “env”.ĬodeIgniter expects. Environment Variables and CodeIgniter ĬodeIgniter makes it simple and painless to set Environment Variables by using a “dotenv” file. For instance, multiple environments, such as the developer’s local machine and the production server, usually need different configuration values for each particular setup.Įnvironment Variables should also be used for anything private such as passwords, API keys, or other sensitive data. Configuration can change a lot across deploys, but code does not. One reason for this is that Environment Variables are easy to change between deploys without changing any code. ![]() One of today’s best practices for application setup is to use Environment Variables. php namespace Config use CodeIgniter\Config\BaseConfig class CustomClass extends BaseConfig Environment Variables The class should use the appropriate namespace, and it should extendĬodeIgniter\Config\BaseConfig to ensure that it can receive environment-specific settings.ĭefine the class and fill it with public properties that represent your settings: The default file location (recommended for most cases) is app/Config. When you need a new configuration, first you create a new file at your desired location. That is not web-accessible while keeping it under /app for easy accessĭuring development. This allows you to put configuration files on the production server in a folder You can put configuration files in any folder you want by using a different namespace. Performance since it knows exactly where to find the files. Using this namespace in your application will provide the best In this tutorial, we have seen what config files are and we have also seen how to create and manipulate config files with the help of the Python configparser module.If no namespace is provided, it will look for the file in all defined namespacesĪll of the configuration files that ship with CodeIgniter are namespaced withĬonfig. In the above example, we can see that remove_option() method takes section name as it’s first argument and field name as it’s the second argument whereas remove_section() method takes the name of the section to be deleted as its argument. remove_option() is used to delete a field from any section and remove_section() is used to delete a complete section of the config file. ![]() We can delete data from config files using remove_option() and remove_section() module in configparser module. If the field given as argument exists in the file, it updates the field otherwise a new field is created. In the above example, we can use update() method to add new fields as well as modify existing fields. In the following code we have added a new field “Year” in “Education” section of person.ini config file and modified the value of “Branch” field in the file. We can add fields in any section of config file or modify the value of the field in a similar manner as we do with dictionary items. How to update data in configuration files?Īs we have defined sections of the config files as dictionaries, the operations applicable on dictionaries are also applicable on sections of config files. These two methods can also be used while making a new config file to add sections and fields to the file instead of using dictionaries as we have done in this example. In the above example, we can see that add_section() method takes section name as it’s argument while set() method takes section name as it’s first argument,field name as it’s second argument and value for field as it’s third argument. ![]()
