How to get value of Selected items of Select2 when submitted? - laravel-5

Question

What options I should set to get the value of the options when I submit the form?
I am using Select2. I have given the code I have to setup the select2, controller that returns the data, the html code that renders the element.
Html Code to add the select2 element:
<div class="form-group row"><label class="col-lg-2 col-form-label">Keyword</label>
<div class="col-lg-10">
<select class="form-control w-50" name="keywords[]" id="keyword" multiple="multiple">
</select>
<span class="form-text m-b-none">One or multiple keywords</span>
</div>
</div>
Datasource is an Ajax call:
$(document).ready(function() {
$('#keyword').select2({
tags: true,
tokenSeparators: [',', ' '],
placeholder: 'Select keyword',
ajax: {
url: 'https://rankypro.dev/app/json/keywords',
dataType: 'json',
delay: 250,
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
text: item.name,
id: item.id
}
})
};
},
cache: true
}
});
Controller:
public function getKeywords(Request $request){
$search = $request->search;
if($search == ''){
$keywords = Term::orderby('name','asc')
->select('id','name')
->where('taxonomy','keyword')
->limit(5)
->get();
}else{
$keywords = Term::orderby('name','asc')->select('id','name')
->where('taxonomy','keyword')
->where('name', 'like', '%' .$search . '%')
->limit(5)
->get();
}
$results = array();
foreach($keywords as $keyword){
$results[] = array(
"id"=>$keyword->id,
"text"=>$keyword->name
);
}
echo json_encode($results);
exit();
}
I am testing with:
public function store(Request $request)
{
dd($request->keywords);
}
I get the following:
array:2 [
0 => "Tools"
1 => "SEO"
]
I actually need ids of the keywords. Would you please give some hints how can I get that.

I think their is some issue in rendering data. Try to replace
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
text: item.name,
id: item.id
}
})
};
},
With
processResults: function (data) {
return {
results: data.item
};
},
select2 automatically render id and name.
