Laravel AJAX: insert with loop (looping DB table row) - php

Question

I'm new in Laravel and Ajax, and I have working code (see below).
I have 2 tables, criteria and rating.
I want to query first the table named:criteria like (select * from criteria where level = 1),
then using the result, I want to save multiple rows in "ratings" using some field of query result + some input variable from user.
Like this:
for (i = 0; i < criteria-result.length; i++) {
$addItem= New Rating;
$addItem->empname = $request->empname; //this is from user this is a repeating value
$addItem->criteria = criteria-result[i].(criteria)
}
Existing Ajax:
$.ajax({
type: 'POST',
url: 'generate-rating-criteria',
data: {
'employee_name': $("#emp_name").text(),
},
success: function()
{
swal("Saved", "Ok", "success")
},
error: function(xhr, status, error)
{
var err = eval("(" + xhr.responseText + ")");
alert(err.Message);
}
});
Existing Controller:
$addItem= New Rating;
$addItem->employee_name = $request->employee_name;
$addItem->save();

You can just use a count() method instead of length.
$criteria = DB::table('criteria')->where('level', 1)->get();
for ($i = 0; $i < count($criteria); $i++) {
$addItem= New Rating;
$addItem->empname = $request->empname;
$addItem->criteria = $criteria[$i]->criteria; /* if criteria column exist in the rating table. */
$addItem->save();
}
