Symfony2 form theme override collection entry row with loop? - php

Question

I have a problem with my form collection entries.
For example my form type.
// ProfileFormType
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name')
->add('emails', 'collection', array(
'type' => new EmailType(),
'allow_add' => true,
'allow_delete' => true
))
;
}
Thats the email type for the collection above.
// EmailType
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('email', 'email')
->add('publicAccess')
;
}
And now the form theme for that collection entry row.
{%- block _fos_user_profile_form_emails_entry_row %}
<div class="email form-group{% if form.email.vars.errors | length %} has-error{% endif %}">
<div class="input-group col-xs-3">
<span class="input-group-addon">{{ form_widget(form.publicAccess) }}</span>
{{ form_widget(form.email) }}
{#% if loop is defined %}{{ dump(loop) }}{% endif %#}
<span class="input-group-btn"><a class="btn btn-success"><span class="glyphicon glyphicon-plus glyphicon-xs"></span></a></span>
</div>
{{ form_errors(form.email) }}
</div>
{% endblock -%}
But the problem is that i have no loop or other things for the entries...
How can i check if the entry is the last entry of the collection?
The reason is that i want to add the "minus" button instead the "glypicon-plus" for all entries which not the last one.

Answer 1

You can access the last entry with :
{% if loop.last %}
{# your custom code for the last entry #}
{% else %}
{# the others entries #}
{% endif %}
So you can use it to choose the good button :
{%- block _fos_user_profile_form_emails_entry_row %}
<div class="email form-group{% if form.email.vars.errors | length %} has-error{% endif %}">
<div class="input-group col-xs-3">
<span class="input-group-addon">{{ form_widget(form.publicAccess) }}</span>
{{ form_widget(form.email) }}
<span class="input-group-btn"><a class="btn btn-success"><span class="glyphicon {{ (loop.last) ? 'glypicon-plus' : 'glyphicon-minus' }} glyphicon-xs"></span></a></span>
</div>
{{ form_errors(form.email) }}
</div>
{% endblock -%}

Answer 2

I think you should compare the entry with the parent's last element.
Like this:
{% if form == form.parent | last %}
it's the last
{% else %}
it's not the last
{% endif %}
