Simple Laravel CRUD Operation Using Laravel 9

Last Updated: | By: PHPFlow Team

This laravel 9 tutorial help to create CRUD operation using laravel 9. CRUD stands for Creating, Reading, Updating, and Deleting resources from the database. I’ll create a controller using the Laravel Resource command.

Laravel very fast and popular PHP MVC framework. The Laravel resource routing assigns the typical “CRUD” routes to a controller with a single line of code.

I will take the employee module as an example to implement CRUD operation in Laravel 9. We will create an employee, read an employee record, update a data, and delete a record.

Laravel has an in-built command to do a specific operation like create controller, create migration file and migrate table, create model, create event and listeners etc, that is grouped under the Artisan command

CRUD Operation Using Resource Controller In Laravel 9

I am using MySQL DB for the employee table and created a connection. I am not using a migration file to handle MySQL table operation, just use SQL to create employee table and insert data.

MySQL Database Connection in Laravel 9

Let’s create a MySQL database connection using .env file. We will create 'test' database and employee table.

--
-- Database: `test`
--

-- --------------------------------------------------------

--
-- Table structure for table `employee`
--

CREATE TABLE `employee` (
  `id` int(11) NOT NULL COMMENT 'primary key',
  `employee_name` varchar(100) NOT NULL COMMENT 'employee name',
  `employee_salary` int(11) NOT NULL COMMENT 'employee salary',
  `employee_age` int(11) NOT NULL COMMENT 'employee age',
  `profile_image` varchar(50) NOT NULL COMMENT 'profile image'
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='datatable demo table';

--
-- Dumping data for table `employee`
--

INSERT INTO `employee` (`id`, `employee_name`, `employee_salary`, `employee_age`, `profile_image`) VALUES
(1, 'Adam', 12322, 23, '');

--
-- Indexes for dumped tables
--

--
-- Indexes for table `employee`
--
ALTER TABLE `employee`
  ADD PRIMARY KEY (`id`);

Created 'employee' table and inserted one record into this table.The employee table has id column which is a primary key.

Please make sure your database settings are correct into app/config/database.php file.There is following entries are important for MySQL connection.

 'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),

Let’s open .env file and passed below data :

DB_DATABASE=laravel
DB_USERNAME=root
DB_PASSWORD=

<h1>All the Employees</h1>


    @foreach($employees as $key => $emp)
        
    @endforeach

<table class="table table-striped table-bordered">

<thead>

            <!-- we will also add show, edit, and delete buttons -->

<td>

                <!-- delete the nerd (uses the destroy method DESTROY /nerds/{id} -->
                <!-- we will add this later since its a little more complicated than the other two buttons -->

                <!-- show the nerd (uses the show method found at GET /nerds/{id} -->
                <a class="btn btn-small btn-success" href="{{ URL::to('employee/' . $emp->id) }}">Show</a>

We have created add new employee record action into EmployeeController file, Now we will create HTML file and added the action method into the form.

<h1>Add Employee Record</h1>


<!-- will be used to show any messages -->
@if (Session::has('message'))

<div class="alert alert-info">{{ Session::get('message') }}</div>

@endif
@if ($errors->any())

<div class="alert alert-danger">

<ul>
            @foreach ($errors->all() as $error)

 	<li>{{ $error }}</li>

            @endforeach
</ul>

</div>

@endif
<form method="post" action="{{ route('employee.store')}}" accept-charset="UTF-8">

<div class="col-md-12">

<div class="form-area">

<div class="alert alert-success hide"></div>

		   <input name="_token" type="hidden" value="{{ csrf_token() }}">

<div class="alert alert-danger hide"></div>


<div class="form-group">
			<input type="text" class="form-control" id="name" name="name" value="{{ old('name') }}" placeholder="Name">
			@if ($errors->has('name'))
			<span class="alert-danger">dsssssssssssssssssss</span>
			@endif
</div>


<div class="form-group">
			<input type="number" pattern="[0-9]*" class="form-control" id="salary" name="salary" placeholder="Salary Number">
</div>


<div class="form-group">
			<input class="form-control" type="number" id="age" name="age" placeholder="age">               
</div>

		  <button type="submit" id="submit" name="submit" class="btn btn-primary pull-right">Submit Employee</button>

<ul>
            @foreach ($errors->all() as $error)

 	<li>{{ $error }}</li>

            @endforeach
</ul>

</div>

@endif


<div class="col-md-12">

<div class="form-area">  
            <form role="form" method="post" action="{{ route('employee.update', $employee->id)}}" accept-charset="UTF-8">

<div class="alert alert-success hide"></div>

               <input name="_token" type="hidden" value="{{ csrf_token() }}">

<div class="alert alert-danger hide"></div>


<div class="form-group">
                <input type="text" class="form-control" id="name" name="name" value="{{$employee->name}}" placeholder="Name">
</div>


<div class="form-group">
                <input type="number" pattern="[0-9]*" class="form-control" id="salary" name="salary" value="{{ $employee->salary }}" placeholder="Salary Number">
</div>


<div class="form-group">
                <input class="form-control" type="number" id="age" name="age" placeholder="age" value="{{ $employee->age }}">               
</div>

              <button type="submit" id="submit" name="submit" class="btn btn-primary pull-right">Submit Employee</button>
            </form>
</div>

</div>

The EmployeeController has two method, one is edit() – that is responsible to display edit template and update() method is used to save data.

The form action is set 'employee.update' to call update() method.
