application's incoming data. It is most common to use the <code>validate</code> method available on all incoming HTTP requests. However, we will discuss other approaches to validation as well.</p> <p>Laravel includes a wide variety of convenient validation rules that you may apply to data, even providing the ability to validate if values are unique in a given database table. We'll cover each of these validation rules in detail so that you are familiar with all of Laravel's validation features.</p> <h2 id="validation-quickstart"><a href="#validation-quickstart">Validation Quickstart</a></h2> <p>To learn about Laravel's powerful validation features, let's look at a complete example of validating a form and displaying the error messages back to the user. By reading this high-level overview, you'll be able to gain a good general understanding of how to validate incoming request data using Laravel:</p> <h3 id="quick-defining-the-routes"><a href="#quick-defining-the-routes">Defining the Routes</a></h3> <p>First, let's assume we have the following routes defined in our <code>routes/web.php</code> file:</p> <pre><code data-theme="olaolu-palenight" data-lang="php" class='torchlight' style='background-color: #292D3E; --theme-selection-background: #7580B850;'><div class='line'><span style="color: #C792EA;">use</span><span style="color: #BFC7D5;"> App\Http\Controllers\</span><span style="color: #FFCB8B;">PostController</span><span style="color: #BFC7D5;">;</span></div><div class='line'> </div><div class='line'><span style="color: #FFCB8B;">Route</span><span style="color: #89DDFF;">::</span><span style="color: #82AAFF;">get</span><span style="color: #BFC7D5;">(</span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">/post/create</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">, [</span><span style="color: #FFCB8B;">PostController</span><span style="color: #89DDFF;">::</span><span style="color: #C792EA;">class</span><span style="color: #BFC7D5;">, </span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">create</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">]);</span></div><div class='line'><span style="color: #FFCB8B;">Route</span><span style="color: #89DDFF;">::</span><span style="color: #82AAFF;">post</span><span style="color: #BFC7D5;">(</span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">/post</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">, [</span><span style="color: #FFCB8B;">PostController</span><span style="color: #89DDFF;">::</span><span style="color: #C792EA;">class</span><span style="color: #BFC7D5;">, </span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">store</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">]);</span></div></code></pre> <p>The <code>GET</code> route will display a form for the user to create a new blog post, while the <code>POST</code> route will store the new blog post in the database.</p> <h3 id="quick-creating-the-controller"><a href="#quick-creating-the-controller">Creating the Controller</a></h3> <p>Next, let's take a look at a simple controller that handles incoming requests to these routes.

<p>Now we are ready to fill in our <code>store</code> method with the logic to validate the new blog post. To do this, we will use the <code>validate</code> method provided by the <code>Illuminate\Http\Request</code> object. If the validation rules pass, your code will keep executing normally; however, if validation fails, an <code>Illuminate\Validation\ValidationException</code> exception will be thrown and the proper error response will automatically be sent back to the user.</p> <p>If validation fails during a traditional HTTP request, a redirect response to the previous URL will be generated. If the incoming request is an XHR request, a <a href="#validation-error-response-format">JSON response containing the validation error messages</a> will be returned.</p> <p>To get a better understanding of the <code>validate</code> method, let's jump back into the <code>store</code> method:</p> <pre><code data-theme="olaolu-palenight" data-lang="php" class='torchlight' style='background-color: #292D3E; --theme-selection-background: #7580B850;'><div class='line'><span style="color: #697098;">/**</span></div><div class='line'><span style="color: #697098;"> * Store a new blog post.</span></div><div class='line'><span style="color: #697098;"> </span><span style="color: #697098;">*/</span></div><div class='line'><span style="color: #C792EA;">public</span><span style="color: #BFC7D5;"> </span><span style="color: #C792EA;">function</span><span style="color: #BFC7D5;"> </span><span style="color: #82AAFF;">store</span><span style="color: #D9F5DD;">(</span><span style="color: #FFCB8B;">Request</span><span style="color: #BFC7D5;"> </span><span style="color: #BEC5D4;">$request</span><span style="color: #D9F5DD;">)</span><span style="color: #89DDFF;">:</span><span style="color: #BFC7D5;"> </span><span style="color: #FFCB8B;">RedirectResponse</span></div><div class='line'><span style="color: #BFC7D5;">{</span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #BEC5D4;">$validated</span><span style="color: #BFC7D5;"> </span><span style="color: #C792EA;">=</span><span style="color: #BFC7D5;"> </span><span style="color: #BEC5D4;">$request</span><span style="color: #89DDFF;">-></span><span style="color: #82AAFF;">validate</span><span style="color: #BFC7D5;">([</span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">title</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;"> </span><span style="color: #89DDFF;">=></span><span style="color: #BFC7D5;"> </span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">required|unique:posts|max:255</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">,</span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">body</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;"> </span><span style="color: #89DDFF;">=></span><span style="color: #BFC7D5;"> </span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">required</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">,</span></div><div class='line'><span style="color: #BFC7D5;"> ]);</span></div><div class='line'> </div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #697098;">//</span><span style="color: #697098;"> The blog post is valid...</span></div><div class='line'> </div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #C792EA;">return</span><span style="color: #BFC7D5;"> </span><span style="color: #82AAFF;">redirect</span><span style="color: #BFC7D5;">(</span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">/posts</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">);</span></div><div class='line'><span style="color: #BFC7D5;">}</span></div></code></pre> <p>As you can see, the validation rules are passed into the <code>validate</code> method.

As mentioned previously, Laravel will automatically redirect the user back to their previous location. In addition, all of the validation errors and <a href="/docs/11.x/requests#retrieving-old-input">request input</a> will automatically be <a href="/docs/11.x/session#flash-data">flashed to the session</a>.</p> <p>An <code>$errors</code> variable is shared with all of your application's views by the <code>Illuminate\View\Middleware\ShareErrorsFromSession</code> middleware, which is provided by the <code>web</code> middleware group. When this middleware is applied an <code>$errors</code> variable will always be available in your views, allowing you to conveniently assume the <code>$errors</code> variable is always defined and can be safely used. The <code>$errors</code> variable will be an instance of <code>Illuminate\Support\MessageBag</code>. For more information on working with this object, <a href="#working-with-error-messages">check out its documentation</a>.</p> <p>So, in our example, the user will be redirected to our controller's <code>create</code> method when validation fails, allowing us to display the error messages in the view:</p> <div class="code-container"> <pre><code data-theme="olaolu-palenight" data-lang="blade" class='torchlight' style='background-color: #292D3E; --theme-selection-background: #7580B850;'><div class='line'><span style="color: #697098;"></span></div><div class='line'> </div><div class='line'><span style="color: #89DDFF;"><</span><span style="color: #FF5572;">h1</span><span style="color: #89DDFF;">></span><span style="color: #BFC7D5;">Create Post</span><span style="color: #89DDFF;"></</span><span style="color: #FF5572;">h1</span><span style="color: #89DDFF;">></span></div><div class='line'> </div><div class='line'><span style="color: #C792EA;">@if </span><span style="color: #BFC7D5;">(</span><span style="color: #BEC5D4;">$errors</span><span style="color: #89DDFF;">-></span><span style="color: #82AAFF;">any</span><span style="color: #BFC7D5;">())</span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #89DDFF;"><</span><span style="color: #FF5572;">div</span><span style="color: #89DDFF;"> </span><span style="color: #FFCB6B;">class</span><span style="color: #89DDFF;">=</span><span style="color: #D9F5DD;">"</span><span style="color: #C3E88D;">alert alert-danger</span><span style="color: #D9F5DD;">"</span><span style="color: #89DDFF;">></span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #89DDFF;"><</span><span style="color: #FF5572;">ul</span><span style="color: #89DDFF;">></span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #C792EA;">@foreach </span><span style="color: #BFC7D5;">(</span><span style="color: #BEC5D4;">$errors</span><span style="color: #89DDFF;">-></span><span style="color: #82AAFF;">all</span><span style="color: #BFC7D5;">() </span><span style="color: #C792EA;">as</span><span style="color: #BFC7D5;"> </span><span style="color: #BEC5D4;">$error</span><span style="color: #BFC7D5;">)</span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #89DDFF;"><</span><span style="color: #FF5572;">li</span><span style="color: #89DDFF;">>{{</span><span style="color: #BFC7D5;"> </span><span style="color: #BEC5D4;">$error</span><span style="color: #BFC7D5;"> </span><span style="color: #89DDFF;">}}</</span><span style="color: #FF5572;">li</span><span style="color: #89DDFF;">></span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #C792EA;">@endforeach</span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #89DDFF;"></</span><span style="color: #FF5572;">ul</span><span style="color: #89DDFF;">></span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #89DDFF;"></</span><span style="color: #FF5572;">div</span><span style="color: #89DDFF;">></span></div><div class='line'><span style="color: #C792EA;">@endif</span></div><div class='line'> </div><div class='line'><span style="color: #697098;"></span></div></code></pre> </div> <h4 id="quick-customizing-the-error-messages"><a href="#quick-customizing-the-error-messages">Customizing the Error Messages</a></h4> <p>Laravel's built-in validation rules each have an error message that is located in your application's <code>lang/en/validation.php</code> file. If your application does not have a <code>lang</code> directory, you may instruct Laravel to create it using the <code>lang:publish</code> Artisan command.</p> <p>Within the <code>lang/en/validation.php</code> file, you will find a translation entry for each validation rule. You are free to change or modify these messages based on the needs of your application.</p> <p>In addition, you may copy this file to another language directory to translate the messages for your application's language.

Form requests are custom request classes that encapsulate their own validation and authorization logic. To create a form request class, you may use the <code>make:request</code> Artisan CLI command:</p> <div class="code-container"> <pre><code data-theme="olaolu-palenight" data-lang="shell" class='torchlight' style='background-color: #292D3E; --theme-selection-background: #7580B850;'><div class='line'><span style="color: #BFC7D5;">php </span><span style="color: #BFC7D5;">artisan</span><span style="color: #BFC7D5;"> </span><span style="color: #BFC7D5;">make:request</span><span style="color: #BFC7D5;"> </span><span style="color: #BFC7D5;">StorePostRequest</span></div></code></pre> </div> <p>The generated form request class will be placed in the <code>app/Http/Requests</code> directory. If this directory does not exist, it will be created when you run the <code>make:request</code> command. Each form request generated by Laravel has two methods: <code>authorize</code> and <code>rules</code>.</p> <p>As you might have guessed, the <code>authorize</code> method is responsible for determining if the currently authenticated user can perform the action represented by the request, while the <code>rules</code> method returns the validation rules that should apply to the request's data:</p> <pre><code data-theme="olaolu-palenight" data-lang="php" class='torchlight' style='background-color: #292D3E; --theme-selection-background: #7580B850;'><div class='line'><span style="color: #697098;">/**</span></div><div class='line'><span style="color: #697098;"> * Get the validation rules that apply to the request.</span></div><div class='line'><span style="color: #697098;"> *</span></div><div class='line'><span style="color: #697098;"> * </span><span style="color: #C792EA;">@return</span><span style="color: #697098;"> </span><span style="color: #C792EA;">array</span><span style="color: #697098;"><</span><span style="color: #C792EA;">string</span><span style="color: #697098;">, \Illuminate\Contracts\Validation\ValidationRule|array<mixed>|string></span></div><div class='line'><span style="color: #697098;"> </span><span style="color: #697098;">*/</span></div><div class='line'><span style="color: #C792EA;">public</span><span style="color: #BFC7D5;"> </span><span style="color: #C792EA;">function</span><span style="color: #BFC7D5;"> </span><span style="color: #82AAFF;">rules</span><span style="color: #D9F5DD;">()</span><span style="color: #89DDFF;">:</span><span style="color: #BFC7D5;"> </span><span style="color: #C792EA;">array</span></div><div class='line'><span style="color: #BFC7D5;">{</span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #C792EA;">return</span><span style="color: #BFC7D5;"> [</span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">title</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;"> </span><span style="color: #89DDFF;">=></span><span style="color: #BFC7D5;"> </span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">required|unique:posts|max:255</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">,</span></div><div class='line'><span style="color: #BFC7D5;"> </span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">body</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;"> </span><span style="color: #89DDFF;">=></span><span style="color: #BFC7D5;"> </span><span style="color: #D9F5DD;">'</span><span style="color: #C3E88D;">required</span><span style="color: #D9F5DD;">'</span><span style="color: #BFC7D5;">,</span></div><div class='line'><span style="color: #BFC7D5;"> ];</span></div><div class='line'><span style="color: #BFC7D5;">}</span></div></code></pre> <div class="mb-10 max-w-2xl mx-auto px-4 py-8 shadow-lg lg:flex lg:items-center callout"> <div class="w-20 h-20 mb-6 flex items-center justify-center shrink-0 lg:mb-0 bg-purple-600"> <div class="opacity-75"><svg width="28" height="40" viewBox="0 0 28 40" xmlns="http://www.w3.org/2000/svg"><title>lightbulb</title><path d="M12 28h4v-8h-4v8zM8 40h12v-8H8v8zm13.98-14.52c-1.001.705-1.661 1.545-1.98 2.52H8c-.416-.959-1.076-1.799-1.98-2.52A13.99 13.99 0 0 1 0 14C0 6.272 6.272 0 14 0s14 6.272 14 14a13.99 13.99 0 0 1-6.02 11.48z" fill="#FFF" fill-rule="nonzero"/></svg></div> </div> <p class="mb-0 lg:ml-6 callout"> You may type-hint any dependencies you require within the <code>rules</code> method's signature.

However, if the user only changes the name field and not the email field, you do not want a validation error to be thrown because the user is already the owner of the email address in question.</p> <p>To instruct the validator to ignore the user's ID, we'll use the <code>Rule</code> class to fluently define the rule.

One method of registering custom validation rules is using rule objects. To generate a new rule object, you may use the <code>make:rule</code> Artisan command. Let's use this command to generate a rule that verifies a string is uppercase. Laravel will place the new rule in the <code>app/Rules</code> directory. If this directory does not exist, Laravel will create it when you execute the Artisan command to create your rule:</p> <div class="code-container"> <pre><code data-theme="olaolu-palenight" data-lang="shell" class='torchlight' style='background-color: #292D3E; --theme-selection-background: #7580B850;'><div class='line'><span style="color: #BFC7D5;">php </span><span style="color: #BFC7D5;">artisan</span><span style="color: #BFC7D5;"> </span><span style="color: #BFC7D5;">make:rule</span><span style="color: #BFC7D5;"> </span><span style="color: #BFC7D5;">Uppercase</span></div></code></pre> </div> <p>Once the rule has been created, we are ready to define its behavior.
