[SOLVED] Fields, Templates and Fieldgroups - how do they interact?

My question was regarding 'fieldgroups' and how they interact with fields and templates when installing things via API.

Fieldgroups currently are just an additional layer of "glue" between templates and fields, and for most they are just a few additional lines to write when assembling templates through the API. There are a few points where that additional layer can add some really nice magic to PW, but even most PW module developers never come across these.

For everyone not deeply into obscure PW vodoo magic, creating a template with fields is always:

• Create a template
• Create a fieldgroup with the same name as the template
• Create your fields, save them and add them to the fieldgroup
• Save the fieldgroup
• Set the fieldgroup in the template
• Save the template

Of course, you can reorder the steps as long as the objects are created before being used and saved after being changed.

Are Fieldgroups required for adding fields to templates? What are these for?

Yes, they are. As written above, they are just a necessary glue.

Hey, great - that's exactly the information I needed! Thank you!

2 last questions:

1) What if I'd like to add fields after the template was saved and how can I add them to the same fieldgroup?

2) Is there always only one field group per template or will/can there be more than one?

Just add them to the template's fieldgroup.

$fg = $template->fieldgroup;
$fg->add($field);
$fg->save();

It is save to assume that there is only one fieldgroup, the one which you can access through $template->fieldgroup (or $template->fields, which is just an alias).

Thanks a lot! Thats all for now! ?
