我已将'credit_impot'自定义字段添加到我的prestashop 1.7中 . 它工作但我无法更新自定义字段 .
这是我的代码
Product.php public $ credit_impot; ...'fields'=> array（'credit_impot'=> array（'type'=> self :: TYPE_STRING），
\ src \ PrestaShopBundle \ Form \ Admin \ Product \ ProductPrice.php $ builder-> add（'credit_impot'，'Symfony \ Component \ Form \ Extension \ Core \ Type \ TextType'，array（'required'=> false，' attr'=> ['placeholder'=> $ this-> translator-> trans（'Andrana'，[]，'Admin.Catalog.Help'）]））;
\ src \ PrestaShopBundle \ Model \ Product \ AdminModelAdapter.php ['step2'=> ['credit_impot'=> $ this-> product-> credit_impot，...
\ src \ PrestaShopBundle \ Resources \ views \ Admin \ Product \ form.html.twig {{form_widget（form.step2.credit_impot）}}
