How to handle AJAX requests in Laravel with jQuery?
Jul 27, 2025 am 12:10 AM
Define the route and controller to handle AJAX requests, 2. Add CSRF token meta tags in the Blade template, 3. Use jQuery to send a POST request carrying CSRF tokens and process the response, 4. Return JSON format response in Laravel and properly handle verification errors, 5. It is recommended to use axios instead of jQuery to obtain better modern JavaScript support. The entire process ensures the security and reliability of AJAX requests, and each step needs to be implemented correctly to ensure complete functions.
Handling AJAX requests in Laravel with jQuery is a common task when building dynamic, responsive web applications. Laravel makes it easy to manage these requests thanks to its built-in CSRF protection, routing, and JSON response support. Here's how to do it properly and securely.
? 1. Set Up Your Route and Controller
First, define a route in routes/web.php that will handle the AJAX request.
// routes/web.php use Illuminate\Http\Request; use App\Http\Controllers\AjaxController; Route::post('/save-data', [AjaxController::class, 'saveData']);
Then create the controller:
// app/Http/Controllers/AjaxController.php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class AjaxController extends Controller
{
public function saveData(Request $request)
{
// Validate the request
$request->validate([
'name' => 'required|string|max:255',
'email' => 'required|email',
]);
// Process data (eg, save to DB)
// User::create($request->all());
return response()->json([
'status' => 'success',
'message' => 'Data saved successfully!'
]);
}
}? 2. Include CSRF Token in Your Blade Template
Laravel requires CSRF protection for POST requests. You must pass the CSRF token with your AJAX request.
In your Blade file, add:
<meta name="csrf-token" content="{{ csrf_token() }}"> This lets jQuery access the token via $('meta[name="csrf-token"]').attr('content') .
? 3. Write jQuery AJAX Code
Now use jQuery to send the AJAX request. Make sure to include jQuery and place this script in your Blade template or external JS file.
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script>
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$('#saveBtn').on('click', function () {
$.ajax({
url: '/save-data',
method: 'POST',
data: {
name: $('#name').val(),
email: $('#email').val()
},
success: function (response) {
alert(response.message);
console.log(response);
},
error: function (xhr) {
if (xhr.status === 422) {
// Validation errors
let errors = xhr.responseJSON.errors;
$.each(errors, function (field, messages) {
alert(messages[0]); // Show first error
});
} else {
alert('An error occurred.');
}
}
});
});
</script>And your form:
<form>
<input type="text" id="name" placeholder="Name">
<input type="email" id="email" placeholder="Email">
<button type="button" id="saveBtn">Save</button>
</form>? 4. Handle JSON Responses and Errors
- Use
response()->json()in Laravel to return structured responses. - In jQuery, check for validation errors (HTTP 422) and other status codes.
- Always validate input on the server side — don't rely on client-side validation.
? Tips & Best Practices
- Use
@csrfor meta token : Both work, but meta token is cleaner for AJAX. - Use
$.ajaxSetup()to set headers globally so you don't repeat CSRF in every request. - Return meaningful JSON : Include
status,message, anddatakeys for consistency. - Avoid exposing sensitive data in responses.
- Test with DevTools : Check Network tab to verify request payload and response.
? Optional: Use Axios instead of jQuery
While jQuery works fine, consider using Axios for modern apps:
axios.post('/save-data', {
name: 'John',
email: 'john@example.com'
})
.then(response => {
console.log(response.data);
})
.catch(error => {
console.error(error.response.data);
});Axios automatically handles JSON and can be configured with CSRF via interceptors.
That's it! You can now securely send and handle AJAX requests in Laravel using jQuery. Just remember: validate on the backend, include the CSRF token, and structure your responses clearly.

How to develop AI intelligent form system with PHP PHP intelligent form design and analysis
Jul 25, 2025 pm 05:54 PM
When choosing a suitable PHP framework, you need to consider comprehensively according to project needs: Laravel is suitable for rapid development and provides EloquentORM and Blade template engines, which are convenient for database operation and dynamic form rendering; Symfony is more flexible and suitable for complex systems; CodeIgniter is lightweight and suitable for simple applications with high performance requirements. 2. To ensure the accuracy of AI models, we need to start with high-quality data training, reasonable selection of evaluation indicators (such as accuracy, recall, F1 value), regular performance evaluation and model tuning, and ensure code quality through unit testing and integration testing, while continuously monitoring the input data to prevent data drift. 3. Many measures are required to protect user privacy: encrypt and store sensitive data (such as AES
How to set environment variables in PHP environment Description of adding PHP running environment variables
Jul 25, 2025 pm 08:33 PM
There are three main ways to set environment variables in PHP: 1. Global configuration through php.ini; 2. Passed through a web server (such as SetEnv of Apache or fastcgi_param of Nginx); 3. Use putenv() function in PHP scripts. Among them, php.ini is suitable for global and infrequently changing configurations, web server configuration is suitable for scenarios that need to be isolated, and putenv() is suitable for temporary variables. Persistence policies include configuration files (such as php.ini or web server configuration), .env files are loaded with dotenv library, and dynamic injection of variables in CI/CD processes. Security management sensitive information should be avoided hard-coded, and it is recommended to use.en

To build a PHP content payment platform, it is necessary to build a user management, content management, payment and permission control system. First, establish a user authentication system and use JWT to achieve lightweight authentication; second, design the backend management interface and database fields to manage paid content; third, integrate Alipay or WeChat payment and ensure process security; fourth, control user access rights through session or cookies. Choosing the Laravel framework can improve development efficiency, use watermarks and user management to prevent content theft, optimize performance requires coordinated improvement of code, database, cache and server configuration, and clear policies must be formulated and malicious behaviors must be prevented.
How to use PHP combined with AI to analyze video content PHP intelligent video tag generation
Jul 25, 2025 pm 06:15 PM
The core idea of PHP combining AI for video content analysis is to let PHP serve as the backend "glue", first upload video to cloud storage, and then call AI services (such as Google CloudVideoAI, etc.) for asynchronous analysis; 2. PHP parses the JSON results, extract people, objects, scenes, voice and other information to generate intelligent tags and store them in the database; 3. The advantage is to use PHP's mature web ecosystem to quickly integrate AI capabilities, which is suitable for projects with existing PHP systems to efficiently implement; 4. Common challenges include large file processing (directly transmitted to cloud storage with pre-signed URLs), asynchronous tasks (introducing message queues), cost control (on-demand analysis, budget monitoring) and result optimization (label standardization); 5. Smart tags significantly improve visual
PHP development user permission management monetization PHP permission control and role management
Jul 25, 2025 pm 06:51 PM
User permission management is the core mechanism for realizing product monetization in PHP development. It separates users, roles and permissions through a role-based access control (RBAC) model to achieve flexible permission allocation and management. The specific steps include: 1. Design three tables of users, roles, and permissions and two intermediate tables of user_roles and role_permissions; 2. Implement permission checking methods in the code such as $user->can('edit_post'); 3. Use cache to improve performance; 4. Use permission control to realize product function layering and differentiated services, thereby supporting membership system and pricing strategies; 5. Avoid the permission granularity is too coarse or too fine, and use "investment"
Explain Laravel Eloquent Scopes.
Jul 26, 2025 am 07:22 AM
Laravel's EloquentScopes is a tool that encapsulates common query logic, divided into local scope and global scope. 1. The local scope is defined with a method starting with scope and needs to be called explicitly, such as Post::published(); 2. The global scope is automatically applied to all queries, often used for soft deletion or multi-tenant systems, and the Scope interface needs to be implemented and registered in the model; 3. The scope can be equipped with parameters, such as filtering articles by year or month, and corresponding parameters are passed in when calling; 4. Pay attention to naming specifications, chain calls, temporary disabling and combination expansion when using to improve code clarity and reusability.
What is Configuration Caching in Laravel?
Jul 27, 2025 am 03:54 AM
Laravel's configuration cache improves performance by merging all configuration files into a single cache file. Enabling configuration cache in a production environment can reduce I/O operations and file parsing on each request, thereby speeding up configuration loading; 1. It should be enabled when the application is deployed, the configuration is stable and no frequent changes are required; 2. After enabling, modify the configuration, you need to re-run phpartisanconfig:cache to take effect; 3. Avoid using dynamic logic or closures that depend on runtime conditions in the configuration file; 4. When troubleshooting problems, you should first clear the cache, check the .env variables and re-cache.
