symfony - Twig and Silex, generating dynamic forms -


i'm trying generate form on twig using 2 loops generate names , every form element. reason i'm getting expression problem, can't find issue. maybe can help.

{% l in 1..line %} <div class="row">     {% r in 1..row %}     {% set form_name = "name_l_"~l~"_r_"~r~"_a" %}      <div class="col-md-{{ cols }}">       {{ form_label(form.~form_name, "line: "~ l ~" total") }}       {{ form_widget(form.~form_name, { attr: { 'class': 'form-control' }}) }}     </div>     {% endfor %} </div> {% endfor %}

you cannot append dynamic variables access members of object. need change:

form.~form_name

to this:

form[form_name]

which achieve looking for.
