Cómo cargar una imagen en Laravel con un ejemplo

En este tutorial, aprenderá cómo cargar una imagen en laravel 8 en la base de datos y el directorio de almacenamiento con validación.

1: Descargar la aplicación Laravel 8

En primer lugar, descargue o instale la nueva configuración de laravel 8. Entonces, abra la terminal y escriba el siguiente comando para instalar la nueva aplicación laravel 8 en su máquina:

composer create-project --prefer-dist laravel/laravel LaravelImage

2: Configurar la base de datos con la aplicación

En este paso, configure la base de datos con su aplicación laravel 8 descargada/instalada. Por lo tanto, debe encontrar el archivo .env y configurar los detalles de la base de datos de la siguiente manera:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database-name
DB_USERNAME=database-user-name
DB_PASSWORD=database-password

3: Crear modelo y migración

En este paso, abra nuevamente su símbolo del sistema. Y ejecute el siguiente comando en él. Para crear un modelo y un archivo de migración para el formulario:

php artisan make:model Photo -m

Después de eso, abra el archivo create_photos_table.php dentro del directorio LaravelImage/database/migrations/ . Y actualice la función up() con el siguiente código:

public function up()
{
    Schema::create('photos', function (Blueprint $table) {
        $table->id();
        $table->string('name');
        $table->string('path');
        $table->timestamps();
    });
}

Luego, abra nuevamente el símbolo del sistema y ejecute el siguiente comando para crear tablas en la base de datos:

php artisan migrate

4: Crear rutas

En este paso, abra el archivo web.php desde el directorio de rutas. Y actualice las siguientes rutas en el archivo web.php:

use App\Http\Controllers\UploadImageController;
 
Route::get('upload-image', [UploadImageController::class, 'index']);
Route::post('save', [UploadImageController::class, 'save']);

5: Crear controlador por comando artesanal

En este paso, ejecute el siguiente comando en el símbolo del sistema para crear un archivo de controlador:

php artisan make:controller UploadImageController

Después de eso, ve a app/http/controllers y abre el archivo UploadImageController.php . Y actualice el siguiente código en él:

<?php
 
namespace App\Http\Controllers;
 
use Illuminate\Http\Request;
use App\Models\Image;
 
 
class UploadImageController extends Controller
{
    public function index()
    {
        return view('image');
    }
 
    public function save(Request $request)
    {
         
        $validatedData = $request->validate([
         'image' => 'required|image|mimes:jpg,png,jpeg,gif,svg|max:2048',
 
        ]);
 
        $name = $request->file('image')->getClientOriginalName();
 
        $path = $request->file('image')->store('public/images');
 
 
        $save = new Photo;
 
        $save->name = $name;
        $save->path = $path;
 
        $save->save();
 
        return redirect('upload-image')->with('status', 'Image Has been uploaded');
 
    }
}

La siguiente línea de código cargará una imagen en el directorio de imágenes :

$path = $request->file('image')->store('public/images');

6: Crear vista de hoja

Ahora, cree un formulario de carga de imágenes en el archivo de vista de hoja para mostrar el formulario de carga de imágenes y enviarlo a la base de datos.

Entonces, vaya a recursos/vistas y cree image.blade.php y actualice el siguiente código en él:

<!DOCTYPE html>
<html>
<head>
  <title>Laravel 8 Uploading Image</title>
 
  <meta name="csrf-token" content="{{ csrf_token() }}">
 
  <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
 
</head>
<body>
 
<div class="container mt-5">
 
  @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 8 Upload Image Tutorial</h2>
    </div>
 
    <div class="card-body">
        <form method="POST" enctype="multipart/form-data" id="upload-image" action="{{ url('save') }}" >
                   
            <div class="row">
 
                <div class="col-md-12">
                    <div class="form-group">
                        <input type="file" name="image" placeholder="Choose image" id="image">
                    @error('image')
                        <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
                    @enderror
                    </div>
                </div>
                   
                <div class="col-md-12">
                    <button type="submit" class="btn btn-primary" id="submit">Submit</button>
                </div>
            </div>     
        </form>
 
    </div>
 
  </div>
 
</div>  
</body>
</html>

El siguiente código a continuación mostrará el mensaje de error de validación en el archivo de vista de hoja:

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

7: Crear directorio de imágenes dentro de almacenamiento/aplicación/público

Ahora, crea el directorio de imágenes dentro del directorio storage/app/public. Porque la siguiente línea de código cargará una imagen en el directorio de imágenes , que se encuentra dentro del directorio storage/app/public/ :

$path = $request->file('image')->store('public/images');

8: Ejecutar servidor de desarrollo

Último paso, abra el símbolo del sistema y ejecute el siguiente comando para iniciar el servidor de desarrollo:

php artisan serve

Luego abra su navegador y presione la siguiente URL:

http://127.0.0.1:8000/image-upload

Php how to delete multiple rows through checkbox using ajax in laravel

First thing, we will need a table and i am creating products table for this example. So run the following query to create table.

CREATE TABLE `products` (
 `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
 `name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
 `description` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
 `created_at` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
 `updated_at` datetime DEFAULT NULL,
 PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=7 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci

Next, we will need to insert some dummy records in this table that will be deleted.

INSERT INTO `products` (`name`, `description`) VALUES

('Test product 1', 'Product description example1'),

('Test product 2', 'Product description example2'),

('Test product 3', 'Product description example3'),

('Test product 4', 'Product description example4'),

('Test product 5', 'Product description example5');

Now we are redy to create a model corresponding to this products table. Here we will create Product model. So let’s create a model file Product.php file under app directory and put the code below.

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    protected $fillable = [
        'name','description'
    ];
}

Step 2: Create Route

Now, in this second step we will create some routes to handle the request for this example. So opeen routes/web.php file and copy the routes as given below.

routes/web.php

Route::get('product', 'ProductController@index');
Route::delete('product/{id}', ['as'=>'product.destroy','uses'=>'ProductController@destroy']);
Route::delete('delete-multiple-product', ['as'=>'product.multiple-delete','uses'=>'ProductController@deleteMultiple']);
