Exploding Value from Select Option Value - laravel

Question

Now I'm working with Laravel 5.
I got value from select option like below:
select name="billing_provider" onChange="changeLanguage(this.value)"> #foreach($tests as $test)
option value="{{ $test->tax_id }},{{ $test->npi }}" name="billing_provider">
{{ $test->test_name }} </option>#endforeach </select>
Here I need to explode the option value and store it into another text field value.
How can I do that?

First, you have made a mistake building your HTML.
<select> has an attribute name which is going to be the key in the global arrays $_GET or $_POST.
However <option> doesn't have attribute name. You should remove that.
If you want to separate the value of billing_provider in your backend (php /w Laravel), do so.
In your method which handles the submission of the form:
$input = Input::get('billing_provider');
$billing_provider = explode(',', $input);
//Now $billing_provider[0] === $test->tax_id
//And $billing_provider[1] === $test->npi
Or if you want to perform this action before form submission and you're using jQuery, then you can do this:
https://jsfiddle.net/17fkpqbe/
JavaScript (/w jQuery):
$(document).ready(function() {
$('select').change(function() {
$('.inputs').html('');
var $explodedVal = $(this).val().split(',');
for(i = 0; i < $explodedVal.length; i++) {
$('.inputs').append('<input value="' + $explodedVal[i]+'">');
}
});
});
HTML:
<select>
<option></option>
<option value="123,555">Some Name 1</option>
<option value="123,444">Some Name 2</option>
<option value="123,333,555">Some Name 3</option>
</select>
<div class="inputs"></div>
