I would like to add some custom config variable in the wp-config file (not in the functions.php). Then, I need to access to these variable in my templates. What is the way to do it ?

I accepted the following answer, just add your custom variable with a define – aguidis Apr 22 '14 at 9:34

Why do you need this?

In wp-config you can set defines. They will be accesible everywhere without needing to use globals. Define something: define('MY_DEFINE_NAME', 'THE_VALUE');.

Then in your templates you can show the value like this: echo MY_DEFINE_NAME;

Or set the value to a variable: $var = MY_DEFINE_NAME;.

Thank you for your quick answer. I need to store some page IDs. The page IDs depend of environments (dev, production etc...). Moreover the functions.php is subversionned contrary to the wp-config.php. This is why I need to store some datas in this file. – aguidis Aug 13 '13 at 13:45
