Laravel : send value of check box to controller without posting? - laravel

Question

I'm using Laravel for my application.
I have made a PRINT button on my HTML page which is simply calling a route, to be able to send it throught DOMPDF to print it to PDF.
Print
Now, in my Controller, I would like to get the value of a radio button which has been created in the HTML this way
<div class="col-lg-7 selectie">
<input type="radio" name="factuur_selectie" id="factuur_selectie" value="1" checked> Alle facturen&nbsp
<input type="radio" name="factuur_selectie" id="factuur_selectie" value="2"> Betaalde facturen
<input type="radio" name="factuur_selectie" id="factuur_selectie" value="3"> Onbetaalde facturen
</div>
In my controller I can not find the way to get the value of the checkbox, I suppose because I'm not doing a submit ?
How would I be able to get the value of the radio button please?
public function printFacturen(Request $request){
}
I already tried three following ways, but it is not working :
$fields = Input::get('factuur_selectie');
$value = $request->get('factuur_selectie');
$request->input('factuur_selectie');
Bestregards,

You need to grab the value of factuur_selectie using JavaScript and add it to the generated URL, something like:
var val = document.querySelector('#factuur_selectie:checked').value;
var btn = document.querySelector('.btn.btn-default');
var url = btn.getAttribute('href');
btn.setAttribute('href', url + '?factuur_selectie=' + val);
Then you should be able to retrieve factuur_selectie from your controller.
Probably you are going to need to update the value everytime an option is selected. In that case you can retrieve the value from then event itself:
var btn = document.querySelector('.btn.btn-default');
document.querySelector('.selectie').addEventListener('change', function(event) {
var val = event.target.value;
var url = btn.getAttribute('href');
var pos = url.indexOf('?');
// If URL already contains parameters
if(pos >= 0) {
// Remove them
url = url.substring(0, pos);
}
btn.setAttribute('href', url + '?factuur_selectie=' + val);
});
Here you have a working example.
