如果要在客户帐户中添加新字段，则需要在自定义主题中覆盖register.phtml。
创建自定义主题，然后在以下路径中创建register.phtml
app / design / frontend / vendor / theme / Magento_Customer / templates / form / register.phtml
然后，从module-customer / view / frontend / templates / form / register.phtml复制代码，然后粘贴到上面创建的文件中。
然后，添加您的自定义字段：
<div class="field required">
<label for="custom_field" class="label"><span><?= __('CustomField') ?></span></label>
<div class="control">
<input type="text" name="custom_field" id="custom_field" value="<?= $block->escapeHtml($block->getFormData()->getCustomField()) ?>" title="<?= __('CustomField') ?>" class="input-text" data-validate="{required:true, 'validate-phoneStrict':true}">
</div>
</div>在此之前，您需要为custom_field创建客户属性以存储数据库。
创建客户属性：
创建自定义模块后，您需要创建一个自定义模块
在以下路径的Vendor \ Module \ Setup中创建InstallData.php
InstallData.php
在下面的代码中，我添加了custom_field属性。
<?php
/**

* See COPYING.txt for license details.
*/
namespace Vendor\Module\Setup;
use Magento\Customer\Setup\CustomerSetupFactory;
use Magento\Customer\Model\Customer;
use Magento\Eav\Model\Entity\Attribute\Set as AttributeSet;
use Magento\Eav\Model\Entity\Attribute\SetFactory as AttributeSetFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
/**
* Install data
* @codeCoverageIgnore
*/
class InstallData implements InstallDataInterface
{
/**
* CustomerSetupFactory
* @var CustomerSetupFactory
*/
protected $customerSetupFactory;
/**
* $attributeSetFactory
* @var AttributeSetFactory
*/
private $attributeSetFactory;
/**
* initiate object
* @param CustomerSetupFactory $customerSetupFactory
* @param AttributeSetFactory $attributeSetFactory
*/
public function __construct(
CustomerSetupFactory $customerSetupFactory,
AttributeSetFactory $attributeSetFactory
)
{
$this->customerSetupFactory = $customerSetupFactory;
$this->attributeSetFactory = $attributeSetFactory;
}
/**
* install data method
* @param ModuleDataSetupInterface $setup
* @param ModuleContextInterface $context
*/
public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
/** @var CustomerSetup $customerSetup */
$customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);
$customerEntity = $customerSetup->getEavConfig()->getEntityType('customer');
$attributeSetId = $customerEntity->getDefaultAttributeSetId();
/** @var $attributeSet AttributeSet */
$attributeSet = $this->attributeSetFactory->create();
$attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId);
/**
* customer registration form default field mobile number
*/
$customerSetup->addAttribute(Customer::ENTITY, 'custom_field', [
'type' => 'varchar',
'label' => 'Custom Field',
'input' => 'text',
'required' => true,
'visible' => true,
'user_defined' => true,
'sort_order' => 1000,
'position' => 1000,
'system' => 0,
]);
//add attribute to attribute set
$attribute = $customerSetup->getEavConfig()->getAttribute(Customer::ENTITY, 'mobile_number')
->addData([
'attribute_set_id' => $attributeSetId,
'attribute_group_id' => $attributeGroupId,
'used_in_forms' => ['adminhtml_customer', 'customer_account_create'],
]);
$attribute->save();
}
}之后，运行以下命令：
php bin/magento setup:upgrade
php bin/magento setup:static-content:deploy
php bin/magento cache:clean您将在注册表单中看到您的自定义文件。
让我知道你是否有问题。
您需要创建一个模块，这里是installData.php：
namespace Barcode\Unique\Setup;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
class InstallData implements InstallDataInterface
{
/**
* Customer setup factory
*
* @var \Magento\Customer\Setup\CustomerSetupFactory
*/
private $customerSetupFactory;
/**
* Init
*
* @param \Magento\Customer\Setup\CustomerSetupFactory $customerSetupFactory
*/
public function __construct(\Magento\Customer\Setup\CustomerSetupFactory $customerSetupFactory)
{
$this->customerSetupFactory = $customerSetupFactory;
}
/**
* Installs DB schema for a module
*
* @param ModuleDataSetupInterface $setup
* @param ModuleContextInterface $context
* @return void
*/
public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
$installer = $setup;
$installer->startSetup();
$customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);
$entityTypeId = $customerSetup->getEntityTypeId(\Magento\Customer\Model\Customer::ENTITY);
$customerSetup->removeAttribute(\Magento\Customer\Model\Customer::ENTITY, "barcode_unique");
$customerSetup->addAttribute(\Magento\Customer\Model\Customer::ENTITY, "barcode_unique", array(
"type" => "varchar",
"backend" => "",
"label" => "Barcode",
"input" => "text",
"source" => "",
"visible" => true,
"required" => false,
"default" => "",
"frontend" => "",
"unique" => false,
"note" => ""
));
$barcode_unique = $customerSetup->getAttribute(\Magento\Customer\Model\Customer::ENTITY, "barcode_unique");
$barcode_unique = $customerSetup->getEavConfig()->getAttribute(\Magento\Customer\Model\Customer::ENTITY, 'barcode_unique');
$used_in_forms[]="adminhtml_customer";
$used_in_forms[]="checkout_register";
$used_in_forms[]="customer_account_create";
$used_in_forms[]="customer_account_edit";
$used_in_forms[]="adminhtml_checkout";
$barcode_unique->setData("used_in_forms", $used_in_forms)
->setData("is_used_for_customer_segment", true)
->setData("is_system", 0)
->setData("is_user_defined", 1)
->setData("is_visible", 1)
->setData("sort_order", 1002);
$barcode_unique->save();
$installer->endSetup();
}
}这将创建一个字段，您可以调用phtml（即：additionalinfocustomer.phtml）文件。
希望对您有帮助。
您可以参考下面的链接在magento2的注册页面上创建自定义字段。
https://github.com/jainmegha5395/custom-fields
该自定义模块将在“注册”表单上添加自定义字段和属性。该属性还将在Magento 2 Admin中以添加或编辑客户表单显示。
