Answer 1

Here what you exactly want : Just for example
<div class="form-group">
{{Form::label('name', trans('admin.venue.fields.name'),['class' => 'col-md-4 control-label'])}}
<div class="col-md-6">
{{Form::text('name',old('name', isset($venue) ? $venue->name : ''),['class' => 'form-control'])}}
</div>
</div>
Model function example :
public function save(Request $request) {
try {
$this->validate($request, Venue::rules(), Venue::messages());
$venue = Venue::saveOrUpdate($request);
if($venue !== false) {
if($request->get('continue', false)) {
return redirect()->route('admin.venue.edit', ['id' => $venue->id])->with('success', trans('admin.venue.save_success'));
} else {
return redirect()->route('admin.venue.index')->with('success', trans('admin.venue.save_success'));
}
} else {
return back()->with('error', "Unable to save venue")->withInput();
}
} catch (\Exception $ex) {
return back()->with('error', "Unable to save venue")->withInput();
}
}
Hope it is useful.

use session() in the value field of ProductName input tag and with some logic, for example
view file:
#if(session()->has('data'))
#if(count(session('data')))
#foreach(session('data') as $data)
<input type="text" class="form-control" name="ProductName" value="{{ $data->prodcut_name }}">
#endforeach
#else
<input type="text" class="form-control" name="ProductName" value="No Data Available">
#endif
#else
<input type="text" class="form-control" name="ProductName">
#endif
and in Controller:
public function postAuth(Request $request) {
$productname = $request->input(productname);
$product_search = Products::where('product_name', $productname)->get();
if($product_search) {
return redirect()->back()->with('data', $product_search);
}
}
