我正在尝试将产品组合选项卡中的“对价格的影响（不含税）”字段替换为 EAN13 字段，因为这样可以更轻松地扫描条形码并在一页上为所有组合添加数量。我选择替换此字段而不添加新字段，因为我可能永远不会使用它。
到目前为止，我通过修改 form_combination.html.twig 文件设法在影响价格的地方显示了我想要的字段。它读取已经拥有 EAN13 的产品的 EAN13，但是如果我在保存产品时尝试添加或修改产品的 EAN13，我会收到一个错误（只保存错误而不是很多信息）。
起初我只是用“EAN13”字段替换了“Impact on price”，当我收到这个错误时，我认为这是因为缺少对价格字段的影响，所以我把它放在 EAN13 所在的位置，但仍然出现保存错误信息。如果我删除产品的 EAN13 并尝试保存它，它会起作用。当我尝试添加新的或替换现有的时，它不会。代码有什么问题？
Here is a pic of where i put the EAN13 field
下面是原代码
<tr class="combination loaded" id="attribute_{{ form.vars.value.id_product_attribute }}" data="{{ form.vars.value.id_product_attribute }}" data-index="{{ form.vars.value.id_product_attribute }}">
<td width="1%"><input class="js-combination" type="checkbox" data-id="{{ form.vars.value.id_product_attribute }}" data-index="{{ form.vars.value.id_product_attribute }}"></td>
<td class="img"><div class="fake-img"></div></td>
<td>{{ form.vars.value.name }}</td>
<td class="attribute-price">
<div class="input-group">
<div class="input-group-prepend">
<span class="input-group-text">{{ default_currency }}</span>
</div>
<input type="text" class="attribute_priceTE form-control text-sm-right" value="{{ form.vars.value.attribute_price }}">
</div>
</td>
我替换为
<tr class="combination loaded" id="attribute_{{ form.vars.value.id_product_attribute }}" data="{{ form.vars.value.id_product_attribute }}" data-index="{{ form.vars.value.id_product_attribute }}">
<td width="1%"><input class="js-combination" type="checkbox" data-id="{{ form.vars.value.id_product_attribute }}" data-index="{{ form.vars.value.id_product_attribute }}"></td>
<td class="img"><div class="fake-img"></div></td>
<td>{{ form.vars.value.name }}</td>
<td class="attribute-price">
<div class="input-group">
<fieldset class="form-group">
<label class="form-control-label">
{{ form.attribute_ean13.vars.label }}
</label>
{{ form_errors(form.attribute_ean13) }}
{{ form_widget(form.attribute_ean13) }}
</fieldset>
</div>
</td>
最终代码如下

答案 0 :(得分：0)
我终于设法让它工作了，所以我发布了解决方案。我知道它不是 100% 正确并且不适合升级，但是如果您想快速将条形码添加到组合中，它的工作非常好。对于任何想知道这是我最终得到的工作代码的人：
Pulp Fiction
9.99
Jumanji
13.99
And so on...
代码从 form_combination.html.twig 的第 25 行开始
我还更改了 form_combinations.html.twig 中的表标题名称，使其显示为 Barcode
