Suppose you have A ModuleRequest that validates your inputs,you can write this method in this class

<pre><code>protected function validationData() 
{
 $all = parent::validationData();
 $all['email'] = encrypt($all['email']);
 return $all;

}
</code></pre>

blocks|key|3753407|text|规则“唯一”和“存在”使用DatabasePresenceVerifier类。所以，您不需要真正扩展唯一的规则，只需访问这个存在验证器。例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3753408|Validator::extend('encrypted_unique',+function+($attribute,+$value,+$parameters,+$validator)+{

++++$count+=+$validator->getPresenceVerifier()->getCount($table,+$column,+encrypt($value),+$ignore_id);
++++return+$count+===+0;
});|code-block|syntax|javascript|3753409|然后你可以像往常一样使用它：|3753410|'identifier'+=>+"encrypted_unique:table,column,$this_id"|3753411|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Rules "unique" and "exists" use the DatabasePresenceVerifier class. So, you don't need to really extend the unique rule, just access this presence verifier. For instance:

<pre><code>Validator::extend('encrypted_unique', function ($attribute, $value, $parameters, $validator) {
 list ($table, $column, $ignore_id) = $parameters; // or hard-coded if fixed
 $count = $validator-&gt;getPresenceVerifier()-&gt;getCount($table, $column, encrypt($value), $ignore_id);
 return $count === 0;
});
</code></pre>

Then you can use it as usual:

<pre><code>'identifier' =&gt; "encrypted_unique:table,column,$this_id"
</code></pre>

Laravel has Custom Validation Rules (<a href="https://laravel.com/docs/8.x/validation#using-rule-objects" rel="nofollow noreferrer">https://laravel.com/docs/8.x/validation#using-rule-objects</a>)
For example I have a table named clients who has two unique fields ecnrypt using Laravel's encryption services (<a href="https://laravel.com/docs/8.x/encryption" rel="nofollow noreferrer">https://laravel.com/docs/8.x/encryption</a>) and because its encrypted, i can't aply the unique directive of validation method (<a href="https://laravel.com/docs/8.x/validation#rule-unique" rel="nofollow noreferrer">https://laravel.com/docs/8.x/validation#rule-unique</a>). The fields are code_client and email
That's the reason of implements a Custom Validation Rules.
this Service has two methods: passes and message. The method passes take two variables: $attributes (take de field to validate) and $value (take de value of field), and return true or false. Te method message retrieve message in case of failure.
In clients example i mentioned, folow the next steps:
<ol>
<li>php artisan make:rule ValidateFieldsClients
</li>
<li>in class that composer creates ValidateFieldsClients, I have to declare a method for validate the fields in passes, I use this method for validate both fields (code_client and email).
</li>
<li>next i complete de method message to retrieve the issue to user in views
</li>
<li>additionally i declare a property $field to identify what´s the field it have the errors
</li>
<li>The class ValidateFieldsClients example:
<pre><code> /***/class ValidateFieldsClients implements Rule{protected $field; /**
 * Create a new rule instance.
 *
 * @return void
 */
 public function __construct()
 { 
 }

 /**
 * Determine if the validation rule passes.
 *
 * @param string $attribute
 * @param mixed $value
 * @return bool
 */
 public function passes($attribute, $value)
 {
 $clients = client::all(); 
 $this-&gt;field = $attribute;

 foreach ($clients as $client ) {
 if ($value == Crypt::decryptString($client-&gt;$attribute)) return false; 
 } 

 return true;
 }

 /**
 * Get the validation error message.
 *
 * @return string
 */
 public function message()
 {
 return strtoupper($this-&gt;field).' exists, check.';
 }
}
</code></pre>
</li>
<li>Then to validate I use Form Request Validation (<a href="https://laravel.com/docs/8.x/validation#form-request-validation" rel="nofollow noreferrer">https://laravel.com/docs/8.x/validation#form-request-validation</a>)
</li>
<li>php artisan make:request ClientRequest
</li>
<li>And in the validate method of the recently created class:
<pre><code>class ClientRequest 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 [ 
 'code_client'=&gt; ['required', new ValidateFieldsClients], 
 'email'=&gt;['required', new ValidateFieldsClients],
 ];
}
</code></pre>
</li>
<li>Finally in controller:
<pre><code> public function store(ClientRequest $request)
 { $clientRequest = $request-&gt;validated();
 foreach ($clientRequest as $key =&gt; $client) {
 $encryptedClient[$key] = Crypt::encryptString($client);
 }; client::create($encryptedClient+ [
 'idorga' =&gt; 1,
 'idcrea' =&gt; 1,
 'idmodifica' =&gt; 1
 ]);

 return redirect('clientes/create')-&gt;with('success', 'Registro creado correctamente');
 //return redirect('cuadros')-&gt;with('success', 'Registro exitoso!');
 }
</code></pre>
</li>
</ol>

I have input <code>$data =['identifier' = 'xxxxxxxxxx'];</code>, and want to save the <code>encrypt($data['identifier'])</code> to the table <code>info</code> primary <code>id</code> column.

I've to validate before save it. Rule <code>unique:info, id</code> isn't suitable here, so I want to write a custom validation rule. And in the custom validation rule, I <code>encrypt()</code> the value first, then use the <code>unique</code> validation rule.

I know how to write a custom validation rule, but how to use the <code>unique</code> validation rule in my custom validation rule?

how to use laravel's validation rule in custom validation rule?
