In our Sf1 project, we had some dilemmas and arguments on how we could do
this better in Symfony 1. And ended up in our code, we have 3 approaches in
our codebase:
- The one suggested by Sf1's doc: <table/>, <form/>, echo $form, and
<input type="submit"/> in template.
- Fully object oriented, I extended the sfForm to support rendering the
HTML elements that are supposed to written in template. Yes, unit testable,
but it puts a limit on how the form formatter choice and also very hard to
further customize the form or its fields.
- Someone in my team was writing a "wizard" module that reuses widgets
from other form classes. She turned out using what you're proposing, in
Symfony 1 would be: $form['field']->render(). This turns out to be a
If I can add an extra thing to what you suggested, I wish that $f->row()
won't be rendering <li/> or <tr/>, as it may waste time for developers or
designs to find a clean/dirty way to add custom objects into the HTML, e.g.
a light bulb, some fancy tips, etc.
The great thing about sfForm is the form processing part, the bind() and
validator's clean(). But the view part is really a nightmare to us.

> <?php echo $f->row('object') ?>

> <?php echo $f->hidden() ?>
>
> <input type="submit" value="Update" />

> I can see several benefits:
>
> * we can drop the need for different layout (table, div, ...);
> * it is clearer than you have total control on the output;
> * no more confusion about the real "value" of echo $form;
> * rendering sub-forms is the developer responsibility (with calls to rows()
> for instance -- more reflection is needed on this one).
