creating a function

Hi,

If i want to create a function to use in various snippets/modules, where do i create the function and is there some special way i’d have to call it?

Thanks.

Hi Gaia,

There’s no special requirements when creating functions etc., you can just create them as you would in normal PHP code.

You can either include the function within your snippet/module code or separate it out into an include file. It all depends on your application - if it’s a function that will be utilised in more than one snippet/module, then I would recommend going down the include file route.

If you do create a separate include file, then a tip is to prefix it with the basepath of your install - makes the code more portable across different setups:

Where you create the files is entirely up to you, but I would recommend that you try and maintain the structure defined in the ’assets’ directory to make life easier in terms of future MODx upgrades.

Hope that helps, Garry

ah ok i see, thanks for the explination Garry

It’s also a good idea to enclose your function in

so your snippet can be used more than once on a page.
