Symfony 验证错误：preg_match()：编译失败：在偏移

如何解决Symfony 验证错误：preg_match()：编译失败：在偏移

当我验证从Symfony 2.x更新到Symfony 4.4的应用程序的运行时，出现以下错误。
我正在验证的功能是输入 ID“！”进行验证并验证验证是否正常工作。半角字母数字字符、下划线 (_)、连字符 (-) 和点 (.) 可用于目标区域。
有什么你能想到的吗？
我删除了 form.errors，但没有用。

错误

preg_match(): Compilation failed: range out of order in character class at offset 13

类型

                $form->add("loginId",TextType::class,array(
                   "required" => false,));

         $resolver->setDefaults(array(
             'validation_groups' => function (FormInterface $form) {
                 $options = $form->getConfig()->getOptions();
                 $loginStaff = $options["login_staff"];
                 $staff = $form->getData();
                 return $this->getValidationGroups($loginStaff,$staff);
             },));
     private function getValidationGroups($loginStaff,$staff)
     {
         $validationGroups = array();
         if ($loginStaff->isManage()) {
             $validationGroups[] = 'manage';
         }
 
         if ($loginStaff->isHq()) {
             if ($staff->getPassword()) {
                 $validationGroups[] = 'hqEdit';
             } else {
                 $validationGroups[] = 'hqNew';
             }
         } else {
             if ($staff->getPassword()) {
                 $validationGroups[] = 'shopEdit';
             } else {
                 $validationGroups[] = 'shopNew';
             }
         }
 
         return $validationGroups;
     }

验证.yaml

    getters:      
        loginId: 
            - Length: { max: 20,groups: [hqInitialSetting,shopInitialSetting,hqEdit,shopEdit] } 
            - Regex:        
                pattern: "/^[a-zA-Z0-9_-.]+$/" 
                groups: [hqInitialSetting,shopEdit]

员工.php

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\AdvancedUserInterface;
use AppBundle\Model\Lib\Parameters;
use Symfony\Component\Security\Core\User\EquatableInterface;
use Symfony\Component\Security\Core\User\UserInterface;
 /**
 *
 * @ORM\Entity(repositoryClass="AppBundle\Model\Repository\StaffRepository")
 * @ORM\Table(name="staff",uniqueConstraints={
 *      @ORM\UniqueConstraint(name="idx_staff_unique",columns={"staff_login_id"}),*      @ORM\UniqueConstraint(name="idx_image_mail_unique",columns={"image_mail"})
 * })
 * @ORM\HasLifecycleCallbacks
 */
class Staff implements AdvancedUserInterface,\Serializable,EquatableInterface
{
    /**
     * @ORM\Column(name="login_id",type="string",length=20,nullable=true,options={"comment"="ID"})
     */
    protected $loginId;

树枝

    {{ form_start(form) }}

        {{ form_errors(form) }}
            <div class="formGroup">
                <div class="formGroup">
                    {{ form_label(form.loginId,'LOGIN ID') }}
                    {{ form_widget(form.loginId) }}
                    {{ form_errors(form.loginId) }}
                </div>
        </div>
        {{ form_rest(form) }}
    {{ form_end(form) }}

解决方法

我更改了正则表达式，效果很好。
由于php版本升级，正则表达式方法可能发生了变化。

pattern: "/^[a-zA-Z0-9-_.]+$/"
