Introduction:
Hey, What’s up, everybody? I hope you are doing fine; today, we will discuss the laravel firstOrCreate function. Laravel’s firstOrCreate function inserts database column row data on a condition basis.
Sounds confusing?? Please follow the steps below and do them on your end for maximum learning output from this post.
First Glance of Laravel firstOrCreate Function:
Please look at the code below. It is a basic structure of a firstOrCreate function. Now, the laravel firstOrCreate function has two parameters.
The first parameter accepts an array for checking the database row’s existence, and the second takes an array for value pairs. The Laravel firstOrCreate function will use value pairs when the first attributes return false, but only in that case.
<?php
use App\Models\Post;
$post = Post::firstOrCreate([
'name' => 'How to use firstOrCreate function'
]);As you can see, we are trying to insert a post name into the database table. Now, when the laravel firstorcreate function finds your post name in the database table, it will not insert it. But if the name is absent, it will insert the new data.
Create a Post without the Laravel firstOrCreate Function
Now, see the second code snippet. This snippet will clarify why you need the laravel firstorcreate function instead of doing this manually. Now, see the code snippet below to understand how our code can repeat so many times.
<?php
namespace App\Http\Controllers;
use App\Models\Post;
use Illuminate\Http\Request;
class PostController extends Controller
{
public function store(Request $request)
{
$post = Post::where('name', $request->name)->first();
if ($post) {
$post= new Post(['name' => $name]);
}
$post->slug = 'CREATED NEW How to use firstOrCreate function';
$post->body = 'post body of how to use firstOrCreate function.';
$post->save();
print_r($post);
}
}Create a Post Using the laravel firstOrCreate Function
Now, look at the updated code snippet below. In this case, we are using this function. It’s a lot cleaner code to look at. Now, we don’t have any redundant codes anymore.
<?php
namespace App\Http\Controllers;
use App\Models\Product;
use Illuminate\Http\Request;
class PostController extends Controller
{
public function store()
{
$post= Post::firstOrCreate([
['name' => 'How to use firstOrCreate function'],
[
$post->slug = 'CREATED NEW How to use firstOrCreate function',
$post->body = 'post body of how to use firstOrCreate function.'
]
);
print_r($post);
}
}From the upper code snippet, we notice that by using the this function, you can prevent our redundant code easily instead of manually doing this. You can check their documentation for more.
Test The Application
At last, we will start our local server using our artisan command. php artisan serve If there is no problem, our code will work fine, and the project will be running now at http://127.0.0.1:8000/ or http://locahost:8000/.
