Message:

I'm pretty new to Laravel and I'm trying to pass data from my controller to the view, which I managed to do as follows:

Controller:

$data['value1'] = 1;

return view('main', $data);

main.blade.php:

{{value1}}

This works fine but now my question is what can I do if I want to change the value of value1 with another method of the controller without refreshing the page?

Are there different approaches or is there one which is most used in Laravel?

Thanks in advance.

My Answer:
One common approach to achieve this in Laravel is to use AJAX requests. You can create a route in your routes/web.php file that will handle the AJAX request and return the updated data.

For example, in your controller, you can create a method that updates the value of value1 and returns the updated data:

php
public function updateValue1() {
$data['value1'] = 2; // Update the value of value1
return response()->json($data);
}


Then, in your routes/web.php file, you can define a route for this method:

php
Route::post('/updateValue1', 'YourController@updateValue1');


In your main.blade.php file, you can use JavaScript to make an AJAX request to the updateValue1 route and update the value without refreshing the page:

javascript
$.ajax({
type: 'POST',
url: '/updateValue1',
success: function(data) {
$('#value1').text(data.value1);
}
});


And in your main.blade.php file, you can display the value using a span tag with an id:

html
{{ $value1 }}


This way, you can update the value of value1 in your controller and reflect the changes in your view without refreshing the page.
