如何在控制器端连接字符串以自动填充表单？

Question

我有一个引导表单，用户在其中输入我想要的电子邮件，如果用户不输入@scoops.com，它会自动连接表单端或控制器端

$customer->email = $request->email;在控制器中，如果想在控制器端检查如何检查用户是否在用户名末尾输入@scoops.com，则可以使用此保存。如果缺少，则将@scoops.com 与用户名连接起来

<div class="form-group">

  <label>Email <span style="opacity: 0.5; font-style: italic; color: red;">(Required)</span></label>

  <div class="input-group">

    <input type="search" name="email" id="email" autocomplete="off" class="form-control input-lg" placeholder="Enter Email" name="name" required="@scoops.com" / onfocus='tmp=this.value;this.value=""' onblur='if(this.value=="")this.value=tmp'>

    <div class="input-group-append">

      <span class="input-group-text">@scoops.com</span>

    </div>

  </div>

  <ul id="suggested-emails" class="list-group"></ul>

  <span id="error_email"></span> 

  @if($errors->has('email'))

    <div class="alert alert-danger">

      {{ $errors->first('email') }}

    </div>

  @endif

</div>

首先，您将检查@scoop.com是否存在，如下所示：&nbsp; &nbsp;use Illuminate\Support\Str;&nbsp; &nbsp;$myString = '@scoop.com';&nbsp; &nbsp;$contains = Str::contains($request->email, '@scoop.com');$contains要么 true 要么 false如果为 false，则连接@scoop.com，如下所示$newString = $request->email.$myString;
