return new class extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('images', function (Blueprint $table) {
$table->id();
$table->string('imageName');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('images');

* @return response
*/
public function upload(Request $request) {
$request->validate([
'image' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
$image = time().'.'.$request->image->extension();
