getting null value at created_at laravel

Question

There a blog create and post functionality in my project.When I create a post I am getting date at created_at field is Jan 01 1970. When I tried to debug it,got null value for this field.I am unable to figure it out.

blog.blade.php

     @foreach($blogs as $blog)
              <div class="blog-container">
              <div class="blog-info">
         <h3><a href="https://africainnovationmarket.org/blog/testing-blog-by-acropolis-11/" title="Testing Blog by Acropolis 11" rel="bookmark">{{$blog->name}}</a></h3>                 <div class="created-blog-info">
                       <div class="create-time"><?php echo date("M d Y",strtotime($blog->created_at));
                       echo $blog->created_at;
                       ?> </div>
                       <?php $name = DB::table('userdetails')->where('id',$blog->created_by)->get();   ?>
                       <div class="create-author">@if($blog->created_by > 0 ) {{$name[0]->firstname}} {{$name[0]->lastname}} @else Admin @endif</div>
                       <div class="sharelinks" style="float:right"></div>
                 </div>
               

            @endforeach

BlogController.php

   public function blog()
    {
        $blogs = DB::table('blogs')->where('delete_status','0')->get();
        return view("home.blog",compact("blogs"));
    }

This is my blog table structure

CREATE TABLE IF NOT EXISTS `blogs` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) COLLATE utf8mb4_unicode_ci NOT NULL,
  `content` text COLLATE utf8mb4_unicode_ci NOT NULL,
  `tags` varchar(55) COLLATE utf8mb4_unicode_ci NOT NULL,
  `created_by` int(11) DEFAULT NULL,
  `updated_by` int(11) DEFAULT NULL,
  `created_at` timestamp NULL DEFAULT NULL,
  `updated_at` timestamp NULL DEFAULT NULL,
  `delete_status` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;     

when I create a blog, created_at field should take that date so that I can get exact value of created_at field instead of null.How should I do it?

Answer 1

use now() while insert the data ref link https://laravel.com/docs/7.x/helpers#method-now

DB::table('blogs')->insert([
    'created_at' => now(), //now is a helper function in laravel  
    'updated_at' => now(),
]); 

or

Blog::create() // it will automatically create both 

Answer 2

If you create a blog model this would be done by Laravel automatically.

Answer 3

You are getting created_at value as null because you did not insert it. Because you did not use a model, you have to insert it manually or you can make a model.

Manually,

DB::table('blogs')->insert(['created_at'= > now()]);

For unix timestamp use now()->timestamp Or make a model,

php artisan make:model Blog

It will create a model. Then You have to create a blog.

Blog::create([]);

By create() method it will insert created_at , updated_at value autometically.
