How to make form_rest() not display a field with Symfony2?

Question

I've started to use Symfony2 but I've some problems. I wanted to render fields by hand but it doesn't work because my field yet rendered by me is displayed with the form_rest() function too, so I have two same fields.

Here is my code :

<div>
     {{ form_errors(form.contenu) }}
     <textarea id="{{ form.contenu.vars.id }}" name="{{ form.contenu.vars.full_name }}">{{ form.contenu.vars.value }}</textarea>
</div>

And, at the form's end, I must put this :

{{ form_rest(form) }}

But it displays the "contenu" field :(

Do you have an idea of what's the problem ?

Is, by any chance, your form called "form"? At which version of Symfony this solution worked for you? I'm trying to do the same but it doesn't work. — userfuser, Sep 29 '13 at 15:41

Another option is to explicitly mark the field as rendered:

{% do form.contenu.setRendered %}

in PHP it would be setRendered(true) ?> – Tomas Dermisek Feb 11 '15 at 01:46

@TomasDermisek No `\Symfony\Component\Form\FormView::setRendered` has no arguments. And since there is no `setUnrendered` and `$rendered` is a private method, you can't use `{{ form_row(form.contenu) }}` later on in your code. – Stephan Vierkant Jun 24 '18 at 14:42

@StephanVierkant, the trick is to first do `{% set formDescription = form_row(form.description) %}` then `{{ form_rest(form) }}` and then `{{ formDescription|raw }}`. – TheFrost Apr 04 '19 at 05:55

Another in my opinion less hacky way to do it is this:

{{ form_widget(form._token) }} // render the CSRF Token
{{ form_end(form, {'render_rest': false}) }} // do not render anything else

It's from the official documentation (v3.0) so it's pretty much best practise i guess.

`{{ form_widget(form._token) }}` – abenevaut Aug 22 '18 at 15:57

{{ form_rest(form) }} goes at the very end, after rendering each field "manually". If you are using it for the CSRF token you can always render it with:

{# Token CSRF #}
{{ form_widget(form._token) }}

very useful in combination with `{{ form_widget(form._token) }}` `{{ form_end(form, {'render_rest': false}) }}` – Barno Dec 19 '13 at 15:53

The situation in which you don't want to show some field suggests badly designed form. You could feed some argument(s) into it's __construct to make it conditional (say, include/exclude some fields) or you could just create separate Form classes (which is, in my opinion, a bit overkill).

I had common case few months ago when form differed when user inserted/updated records. It was something like this:

...
public function __construct($isUpdateForm){
    $this->isUpdateForm= $isUpdateForm;
}

public function buildForm(FormBuilder $builder, array $options){
    ....
    $builder->add('some_filed', 'text', ..... );

    if ( $this->isUpdateForm ){
        $builder->add(.....);
    }
    ....
}
....

If for some reasons you're not able to refactor form class you could still display unwanted fields but wrap them into <div> which has CSS display:none attribute. That way "they are still there" (and by all means are processed normally) but are not visible to user.

Hope this helps...

Thank, but that wasn't what I want (I've found a solution, see my EDIT). I wanted to say to Symfony I've already display the field ;) — Ilan Coulon, May 15 '12 at 16:11
Even better would be different forms for adding or updating an entity. My experience is that you'll add `$isUpdateForm` to your constructor, later on you'll add `$isAdmin` and `$isOwner`, etc. etc. — Stephan Vierkant, Jun 24 '18 at 14:46
@StephanVierkant while I had no such case so far, that is certainly a possibility. But then, with individual forms, dev should pay attention to minimize duplication (or have none at all). Nothing is worse than fixing a bug in one place, just to uncover that there is a same snippet that you really haven’t been aware of at all... :-) — Jovan Perovic, Jun 24 '18 at 14:53
