Answer 1

It looks like you are sending null value for the title and to catch out the validation errors earlier on in your application, you should consider introducing some validation in your controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\post;
class postcontroller extends Controller
{
public function store(Request $request)
{
$request->validate([
'title' => 'required',
'body' => 'required',
]);
$add = Post::create([
'title' => $request->input('title'),
'body' => $request->input('body')
]);
session()->flash('msg','new post added successfully!');
return redirect()->route('posts.show', $add->id);
}
Make sure you have set the title and body fields in your form correctly
<form><!-- / Dont forget the action, crf and other required attr of form -->
<input type="text" name="title">
<textarea name="body"></textarea>
</form>
