How to use conditional classes and styles in Blade in Laravel?

Aug 01, 2025 am 07:24 AM

Use the @class directive to dynamically apply CSS classes, for example: 1. Use @class to combine condition variables to add active classes to active menu items; 2. Use ternary operators to inline judge styles in class attributes; 3. Use style attributes to combine ternary operators or PHP variables to dynamically set inline styles; 4. Pass and merge condition classes in Blade component; 5. Encapsulate complex logic into model attributes or helper functions, such as returning the corresponding style class of the state through getStatusClassAttribute method, and finally call it in Blade to keep the template clear and maintainable.

How to use conditional classes and styles in Blade in Laravel?

In Laravel's Blade templating engine, you can dynamically apply CSS classes or inline styles based on conditions — which is super useful for things like active navigation links, form validation states, or UI toggles. Here's how to do it cleanly and efficiently.

How to use conditional classes and styles in Blade in Laravel?

1. Using @class for Conditional Classes

Laravel provides the @class directive (available in Laravel 7 ) to dynamically manage CSS classes. It merges static and conditional classes, automatically handling spacing.

Example: Active menu item

How to use conditional classes and styles in Blade in Laravel?
 @php
    $isActive = request()->is('dashboard');
@endphp

<div @class([
    &#39;nav-link&#39;,
    &#39;active&#39; => $isActive,
    &#39;disabled&#39; => !$user->isActive(),
])>
    Dashboard
</div>

This compiles to:

 <div class="nav-link active">Dashboard</div>

Only classes with true values are included.

You can also mix strings and conditions:

 @component(&#39;alert&#39;, [&#39;type&#39; => &#39;error&#39;])
    @class(["alert", "alert-{$type}" => $type])
@endcomponent

2. Using Ternary Operators with class=""

If you're not using @class , or need a quick inline solution, use standard HTML with ternary logic:

 <li class="{{ request()->is(&#39;profile&#39;) ? &#39;active&#39; : &#39;&#39; }}">
    <a href="/profile">Profile</a>
</li>

Or with multiple conditions:

 <div class="{{ $hasError ? &#39;text-red-500&#39; : &#39;text-gray-800&#39; }} {{ $isBold ? &#39;font-bold&#39; : &#39;&#39; }}">
    Some text
</div>

This works fine for simple cases but can get messy with many classes.


3. Conditional Inline Styles with

You can also conditionally apply inline styles:

 <div style="{{ $isUrgent ? &#39;color: red; font-weight: bold;&#39; : &#39;color: gray;&#39; }}">
    {{ $message }}
</div>

Or build the style dynamically:

 @php
    $styles = [];
    if ($isLarge) $styles[] = &#39;font-size: 24px&#39;;
    if ($isCentered) $styles[] = &#39;text-align: center&#39;;
@endphp

<p style="{{ implode(&#39;; &#39;, $styles) }}">
    Styled paragraph
</p>

4. Combining Dynamic Classes with Components

When using Blade components, you can pass classes and conditionally merge them:

 <x-button :class="[&#39;w-full&#39; => $block]" />

Inside the component:

 <button class="{{ $class ?? &#39;&#39; }} px-4 py-2 bg-blue-500">
    {{ $slot }}
</button>

This lets users extend or override classes while preserving internal logic.


Bonus: Use Helper Functions or Accessors

For complex logic, consider moving class logic into methods:

In your model:

 public function getStatusClassAttribute()
{
    return match($this->status) {
        &#39;active&#39; => &#39;text-green-500&#39;,
        &#39;pending&#39; => &#39;text-yellow-500&#39;,
        &#39;inactive&#39; => &#39;text-gray-400&#39;,
    };
}

In Blade:

 <span class="{{ $user->status_class }}">
    {{ $user->status }}
</span>

Basically, use @class when you can — it's clean and built for this. For styles or simpler cases, inline ternaries work fine. Keep logic out of templates when it gets complex, and lean on PHP attributes or helpers.

Creating Custom Validation Rules in a Laravel Project Creating Custom Validation Rules in a Laravel Project Jul 04, 2025 am 01:03 AM

There are three ways to add custom validation rules in Laravel: using closures, Rule classes, and form requests. 1. Use closures to be suitable for lightweight verification, such as preventing the user name "admin"; 2. Create Rule classes (such as ValidUsernameRule) to make complex logic clearer and maintainable; 3. Integrate multiple rules in form requests and centrally manage verification logic. At the same time, you can set prompts through custom messages methods or incoming error message arrays to improve flexibility and maintainability.

Understanding Dependency Injection in Laravel? Understanding Dependency Injection in Laravel? Jul 05, 2025 am 02:01 AM

Dependency injection automatically handles class dependencies through service containers in Laravel without manual new objects. Its core is constructor injection and method injection, such as automatically passing in the Request instance in the controller. Laravel parses dependencies through type prompts and recursively creates the required objects. The binding interface and implementation can be used by the service provider to use the bind method, or singleton to bind a singleton. When using it, you need to ensure type prompts, avoid constructor complications, use context bindings with caution, and understand automatic parsing rules. Mastering these can improve code flexibility and maintenance.

Strategies for optimizing Laravel application performance Strategies for optimizing Laravel application performance Jul 09, 2025 am 03:00 AM

Laravel performance optimization can improve application efficiency through four core directions. 1. Use the cache mechanism to reduce duplicate queries, store infrequently changing data through Cache::remember() and other methods to reduce database access frequency; 2. Optimize database from the model to query statements, avoid N 1 queries, specifying field queries, adding indexes, paging processing and reading and writing separation, and reduce bottlenecks; 3. Use time-consuming operations such as email sending and file exporting to queue asynchronous processing, use Supervisor to manage workers and set up retry mechanisms; 4. Use middleware and service providers reasonably to avoid complex logic and unnecessary initialization code, and delay loading of services to improve startup efficiency.

Managing database state for testing in Laravel Managing database state for testing in Laravel Jul 13, 2025 am 03:08 AM

Methods to manage database state in Laravel tests include using RefreshDatabase, selective seeding of data, careful use of transactions, and manual cleaning if necessary. 1. Use RefreshDatabasetrait to automatically migrate the database structure to ensure that each test is based on a clean database; 2. Use specific seeds to fill the necessary data and generate dynamic data in combination with the model factory; 3. Use DatabaseTransactionstrait to roll back the test changes, but pay attention to its limitations; 4. Manually truncate the table or reseed the database when it cannot be automatically cleaned. These methods are flexibly selected according to the type of test and environment to ensure the reliability and efficiency of the test.

Choosing between Laravel Sanctum and Passport for API authentication Choosing between Laravel Sanctum and Passport for API authentication Jul 14, 2025 am 02:35 AM

LaravelSanctum is suitable for simple, lightweight API certifications such as SPA or mobile applications, while Passport is suitable for scenarios where full OAuth2 functionality is required. 1. Sanctum provides token-based authentication, suitable for first-party clients; 2. Passport supports complex processes such as authorization codes and client credentials, suitable for third-party developers to access; 3. Sanctum installation and configuration are simpler and maintenance costs are low; 4. Passport functions are comprehensive but configuration is complex, suitable for platforms that require fine permission control. When selecting, you should determine whether the OAuth2 feature is required based on the project requirements.

Implementing Database Transactions in Laravel? Implementing Database Transactions in Laravel? Jul 08, 2025 am 01:02 AM

Laravel simplifies database transaction processing with built-in support. 1. Use the DB::transaction() method to automatically commit or rollback operations to ensure data integrity; 2. Support nested transactions and implement them through savepoints, but it is usually recommended to use a single transaction wrapper to avoid complexity; 3. Provide manual control methods such as beginTransaction(), commit() and rollBack(), suitable for scenarios that require more flexible processing; 4. Best practices include keeping transactions short, only using them when necessary, testing failures, and recording rollback information. Rationally choosing transaction management methods can help improve application reliability and performance.
