Undefined variable: img_name

Answer 1

If $request->hasFile('p_image') is false you don't define the $img_name variable.
But you always execute the code
Image::create([
'p_image' => $img_name,
'post_id' => $post->id
]);
which is wrong. Change your code to
if($request->hasFile('p_image')){
$img_name = time() . '.' . $request->p_image->getClientOriginalExtension();
$request->p_image->move(public_path('upload'), $img_name);
Image::create([
'p_image' => $img_name,
'post_id' => $post->id
]);
}
