Laravel 8 "not required" validation rule - laravel

Question

how can I "tell" laravel that if the email field with validation rule 'email' and URL field (for example field where I expect the user to put his Facebook account link but that field IS NOT required) with validation rule 'URL' is not required and it is fine if it is empty. I have put nullable() on all database table columns but my validation rule still applies like it is required. Here are the parts of the code.
This is from migration:
$table->string('site_facebook')->nullable();
$table->string('site_instagram')->nullable();
$table->string('site_twitter')->nullable();
$table->string('site_linkedin')->nullable();
$table->string('site_behance')->nullable();
$table->string('site_dribbble')->nullable();
$table->string('site_email')->nullable();
This part is from validation:
'site_facebook' => 'url',
'site_facebook' => 'url',
'site_instagram' => 'url',
'site_twitter' => 'url',
'site_linkedin' => 'url',
'site_behance' => 'url',
'site_dribbble' => 'url',
'site_email' => 'email',
So, to wrap up my question. I want my URL and email fields to be optional not required :)
EDIT
Since there are some answers and no one work for me I just want to mention (if it does do anything with it), all of my validation rules are in a separate request...
class ManageSiteSettingsRequest extends FormRequest
{
/**
* Determine if the user is authorized to make this request.
*
* #return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* #return array
*/
public function rules()
{
return [
'site_name' => 'required|max:50',
'site_facebook' => 'nullable|url',
'site_facebook' => 'url',
'site_instagram' => 'url',
'site_twitter' => 'url',
'site_linkedin' => 'url',
'site_behance' => 'url',
'site_dribbble' => 'url',
'site_email' => 'email',
'site_creator_link' => 'url',
];
}
}
This is the form:
#extends('layouts.admin')
#section('content')

Answer 1

You can use nullable rule
Like the example below:
'site_facebook' => 'url|nullable',
