Laravel Drop dowm menu filter

Using PHP Laravel and JavaScript, I am creating a dropdown menu as a filter or search feature. The results will be displayed below the dropdown menu. The filter for location is working, but the other two dropdowns, which are for type and project name, are not functioning. Can you please assist me with this issue? Thank you.

I have attempted to modify the JavaScript and model to see if there are any improvements.

this is the .blade.php

this is the web controller

public function index(Request $request)
{
session(['message' => 'Incident Management Report', 'icon' => 'bi bi-exclamation-triangle-fill', 'icon-code' => '']);
$incidenttype = SystemIncidentType::orderBy('type_name', 'asc')->get();
$systemapps = SystemApps::orderBy('syst_xname', 'asc')->get();
$location = ModLocation::orderBy('loc_name', 'asc')->get();
$incidentReports = IncidentReports::with('userbasic', 'useremp')->get();
return view('pages.incident_management_report.reports', compact('incidenttype', 'systemapps', 'location', 'incidentReports'));
}

this is the api controller

public function irReports(Request $request)
{
if ($request->ajax()) {
$location = $request->input('location');
$type = $request->input('type');
$project = $request->input('project');
$query = IncidentReports::query();
if ($location) {
$query->where('incident_location', $location);
}
if ($type) {
$query->where('incident_type', $type);
}
if ($project) {
$query->where('incident_affected', $project);
}
$data = $query->get();
return response()->json($data);
}
}

this the api routes

Route::post('ir/reports', [IncidentReportsController::class, 'irReports'])->name('ir.reports');

You're using same name for select box Project Name and Type with "irtype", so it would fetch the value of last select box i.e, project name value and search for type with project name input value. So there may no records with search value.

Update your selectbox name and id, then try
