Arbitrary Settings
How to Use
Once your settings are created and populated, now you'll want to actually use them in your code! This is really very simple. Click on the "How to Use" navigation link in the module and copy and paste the code into your PHP page. Note: if your page already include the Form Tools API or the library.php, you won't need to re-include it.
As the page describes, you can use the $settings var to access any of the values you want. Note that checkbox and multi-select field will have their (multiple) values serialized into a pipe-delimited string. To convert them to an array, just explode("|", $settings["your_setting_identifier"]).
