收藏的Symfony表单自定义主题

Question

我有一个 Symfony Form 集合，我正在尝试使用自定义主题自定义渲染的外观。

虽然

_basket_form_basket_items_widget

似乎不匹配。我已经使用

integer_widget

验证了主题正在运行

但是参考 Symfony 文档，上面的内容看起来应该有效？

我也试过：

_basket_form_basket_items_entry_widget

_basket_form_basket_items_qty_widget

_basket_form_basket_items_integer_widget

_basket_form_integer_widget

# src/templates/form/es_theme.html.twig

{# For view basket form #}
{% block _basket_form_basket_items_widget %}
    <div class="form-group row">
        <label for="{{ id }}" class="col-sm-1 col-form-label">{{ label }}</label>
        <div class="col-sm-11">
            <input type="number" name="{{ full_name }}" class="form-control" id="{{ id }}" min="{{ attr.min }}" value="{{ value }}">
        </div>
    </div>

Answer 1

我设法解决了这个问题。

我在

var_dump($blockName)

（Symfony 6.2）中放了一个

vendor/symfony/twig-bridge/Form'TwigRendererEngine.php

，它显示了所有可能的块名称。

我要找的区块名称是

_basket_form_basketItems_entry_qty_widget
