Consider a view file with name demo.blade.php which exists inside /resources/views folder.
In controller to check this view file as,
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class DemoController extends Controller
{
public function checkViewFile()
{
if (view()->exists('demo')) {
echo "Exists";
} else {
echo "Not Exists";
}
}
}
view()->exists(‘demo’) this line is looking for demo.blade.php view file inside /resources/views folder of application.
Blade (View) Template File inside Subfolder
The same view file i.e demo.blade.php, consider inside /resources/views/admin folder.
In controller to check this view file as,
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class DemoController extends Controller
{
public function checkViewFile()
{
if (view()->exists('admin.demo')) {
