Symfony2: how to render form submit separately - php

Question

I'm creating a form in Symfony2 that contains more than one submit button. I need to control where these buttons are rendered. I tried the following, but naturally nothing happens.
<h1>Search Form</h1>
<div id="search_form">
{{ form(formSearch) }}
</div>
<div id="search_tasks">
Tasks:
{{ form_widget(formSearch.searchButton1) }}
{{ form_widget(formSearch.searchButton2) }}
</div>
The search buttons are declared in the form class; they are rendered inside #search_form and nothing shows up in #search_tasks.

Answer 1

You are already rendering the whole form with {{ form(formSearch) }} (fields and buttons are only rendered once).
You need to render the start, rows and end separately.
{{ form_start(formSearch) }}
<h1>Search Form</h1>
<div id="search_form">
{{ form_row(formSearch.field1) }}
{{ form_row(formSearch.field2) }}
{{ form_row(formSearch.field3) }}
</div>
<div id="search_tasks">
Tasks:
{{ form_widget(formSearch.searchButton1) }}
{{ form_widget(formSearch.searchButton2) }}
</div>
{{ form_end(formSearch) }}

I ran into the same issue where I needed my Submit and Reset buttons to be on the same row. My forms are dynamic so there was no way I could output the fields individually. I captured the buttons' HTML first so that form_widget(form) wouldn't output them for me.
{% form_theme form 'AppBundle::form/form_layout.html.twig' %}
<div class="row">
{{ form_start(form) }}
{% if form.submit is defined %}
{% set submitButton = form_widget(form.submit) %}
{% endif %}
{% if form.reset is defined %}
{% set resetButton = form_widget(form.reset) %}
{% endif %}
{{ form_widget(form) }}
<div class="form-group row">
{% if submitButton is defined %}
{{ submitButton|raw }}
{% endif %}
{% if resetButton is defined %}
{{ resetButton|raw }}
{% endif %}
</div>
{{ form_end(form) }}
</div>
