Symfony：如何在foreach循环中动态创建表单

Question

我有一个包含隐藏字段的表单，它使用此字段向操作发送一个变量，该变量指示要删除的项的ID。我有一个表显示数据库表'profil'的内容，每行都有一个按钮“supprimer”删除这一行，但正如我所说，它只删除第一行。 Apparentlu这个循环只为第一个项创建一个表单，所以我想为表中的每个项创建这个表单。

 {% if profils %}
           <div id="prof_table">
            <table style="background-color: #f9f9f9;position: absolute;top:10vmin;left: 5vmin;"
                   class="table table-responsive table-bordered">
                <tr>
                    <th style="color: #1b6d85"> Identificateur </th>
                    <th style="color: #1b6d85"> Libellé</th>
                    <th style="color: #1b6d85"> Actions</th>
                </tr>
                {% for profil in profils %}
                <tr><td>{{ profil.id }}</td><td>{{ profil.libelle }}</td>
                    <td>
                        <button id="delete" class="btn btn-danger btn-xs">
                            <a data-fancybox data-src="#hidden-content3" href="javascript:;"
                               style="color: #ffffee;text-decoration: none;">Supprimer</a>
                        </button>
                    </td></tr>

                    <!-- HERE IS THE POPUP FORM TO DELETE PROFILES-->
                    <div style="display: none; height: 40vh; width: 30vw;" id="hidden-content3">
                        <span style="position:relative;top:10vmin;font-size: medium;"></span>
                    {% if form3 %}
                            <label style="display:inline-table;">
                                <span style="font-size: medium;">Etes vous surs de vouloir supprimer ce profil?</span>
                            </label>
                        </section>
                        {{ form_start(form3, { attr: {novalidate: 'novalidate'} }) }}
                        <section class="col-lg-9 col-md-9 col-sm-9 col-xs-9" style="position: relative; left: 5vmin;top: 6vmin">

                        </section>
                        {{ form_end(form3) }}
                    {% endif %}
