Laravel POST request not reaching controller with Inertia.js

Laravel POST request not reaching controller with Inertia.js

When making a POST request using Inertia.js in Laravel, the request may not reach the controller. This issue can occur due to several reasons, such as incorrect routing, CSRF token validation failure, or incorrect request data. In this answer, we will discuss the common causes and solutions for this problem.

1. Incorrect Routing: Make sure that the route defined in your JavaScript file matches the route defined in your Laravel controller. You can check the routes file in Laravel and the JavaScript file to ensure they match. For example, if your Laravel route is defined as /posts, make sure that your Inertia.js file uses the same route.

2. CSRF Token Validation Failure: In Laravel, by default, POST requests require a valid CSRF token. Inertia.js does not automatically include the CSRF token in the request headers. To solve this issue, you need to manually include the CSRF token in the request headers. You can do this by adding the following code to your JavaScript file:

import axios from 'axios';

const token = document.head.querySelector('meta[name="csrf-token"]');

axios.defaults.headers.common['X-CSRF-TOKEN'] = token.content;

3. Incorrect Request Data: Make sure that the data you are sending in the request is in the correct format. In Laravel, the request data is accessible through the $request variable in the controller. You can check the $request->all() method to see the entire request data. In Inertia.js, you can send data as a JavaScript object in the put or post method. For example:

this.$inertia.post('/posts', { title: 'New Post Title', body: 'New Post Body' });

Make sure that the keys in the JavaScript object match the keys in the Laravel controller.

4. Middleware: If you have any middleware that is preventing the request from reaching the controller, you may need to modify the middleware to allow the request through. You can check the middleware files in the app/Http/Kernel.php file to see if there are any middleware that may be causing the issue.

5. Server Configuration: If none of the above solutions work, you may need to check your server configuration. For example, if you are using a reverse proxy server, you may need to configure it to forward the CSRF token to the Laravel application.

In conclusion, when making a POST request using Inertia.js in Laravel, there are several common causes for the request not reaching the controller. By checking the routing, CSRF token validation, request data, middleware, and server configuration, you can identify and solve the issue.
