<!DOCTYPE html>
<html>
<head>
    <title>Laravel 9 Form Validation</title>

<link href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" rel="stylesheet">

</head>
<body>

<div class="container mt-4">

  @if(session('status'))
    <div class="alert alert-success">
        {{ session('status') }}
    </div>
  @endif

  <div class="card">
    <div class="card-header text-center font-weight-bold">
      <h2>Laravel 9 Form Validation</h2>
    </div>
    <div class="card-body">
      <form name="employee" id="employee" method="post" action="{{url('store-form')}}">

        <div class="form-group">
          <label for="exampleInputEmail1">Name</label>
          <input type="text" id="name" name="name" class="@error('name') is-invalid @enderror form-control">
          @error('name')
              <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
          @enderror
        </div>

        <div class="form-group">
          <label for="exampleInputEmail1">Email</label>
          <input type="email" id="email" name="email" class="@error('email') is-invalid @enderror form-control">
          @error('email')
              <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
          @enderror
        </div>

        <div class="form-group">
          <label for="exampleInputEmail1">Age</label>
          <input type="number" id="age" name="age" class="@error('age') is-invalid @enderror form-control">
          @error('age')
              <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
          @enderror
        </div>

        <div class="form-group">
          <label for="exampleInputEmail1">Contact No</label>
          <input type="number" id="contact_no" name="contact_no" class="@error('contact_no') is-invalid @enderror form-control">
          @error('contact_no')
              <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
          @enderror
        </div>

        <button type="submit" class="btn btn-primary">Submit</button>
      </form>
    </div>
  </div>
</div>
</body>
</html>

The following below code will display validation error message on blade view file:

  @error('name')
  <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
  @enderror

Step 7 – Run Development Server
