表格不提交 - Symfony2

Question

why does my symfony2 Form not submit? If i press the submit-button, nothing happens.

I want not the default-form {{ form(form) }}. The default form works. The error seems to be in TWIG?

{% extends '::base.html.twig' %}
{% block stylesheets %}
    {{ parent() }}

    <link href="{{ asset('css/essensplan/show.css') }}" rel="stylesheet" />
    <!-- Latest compiled and minified CSS -->
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">

    <!-- Optional theme -->
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap-theme.min.css">


{% endblock %}

{% block body -%}

{{ form_start(form)  }}

    <h1>Speiseplan für KW {{ kw }}</h1>

        <form action = "" method = "post">
            <input type="submit" name="back" value="<" class="btn-lg btn-success"/>
            <input type="submit" name="next" value=">" class="btn-lg btn-success" />

            <input type="hidden" name="kw" value="{{ kw }}">
        </form>

        <div class="container-fluid">

        <div class="tag col-xs-3">
                <div class="wochentag">

                </div>
                <div class="hauptgericht">
                         <div class="h"><strong>Hauptgericht</strong></div>
                         <div class=""> {{ form_widget(form.montagHauptgericht) }}
                          </div>

                </div>

}

Thanks for your help.

Answer 1

It seems that you have nested forms in your markup (first one coming from twig's {{ form }} second is in markup. According to this or this you are not allowed to nest form tags. This might be the reason your form is not submitting properly
