I’m facing a recurring issue with my Magento 2 custom module that involves a form within a chat interface on my website. Upon submitting the form through a POST request, I’m redirected to the homepage, receiving a 302 Found response. This prevents my controller logic from functioning as intended.
I aim to build a messaging service using the OpenAI API, which would allow messages from the chat popup to be processed by my PHP code. This setup should enable me to query products from Magento, send that information to ChatGPT, and display the response in the chat. Unfortunately, I can’t get the message to send or receive a response from my controller.
The module is active, and the chatbot UI is loading correctly, indicating that the front-end technologies are all operational. The challenge seems to be with the PHP backend and AJAX handling. Although I’ve explored numerous AI resources and tutorials, the issue keeps occurring. My Magento 2 site is fairly new, and while I’ve developed my custom module knowledgeably over the last few days, I’m stuck with this problem. Any advice on how to troubleshoot would be immensely helpful. Here’s my code structure for reference.
It sounds like your issue could be related to form validation or CSRF token verification failing, which can trigger a 302 redirect to the homepage by Magento 2. Make sure that your form includes a valid form_key. This token ensures that the request comes from a legitimate source and helps prevent CSRF attacks. In your AJAX call, ensure you are passing the token in the request, usually available via php echo $block->getFormKey();. Double-check your controller’s permissions set in the acl.xml to ensure the right access control is configured for your request. If these elements don’t resolve the issue, consider checking your routes.xml and ensure the endpoint is correctly defined and accessible.
Heyy! Double-check your action attribute in the form tag, it should point directly to your controller’s URL. Also, make sure any session redirects or custom return URLs aren’t interfering after form submission. Enabling logs could help spot any hidden errors during the request too. Good luck! 
hii Ryan! It’s worth checking if there are any custom before or after plugins meddling with the Controller output. Another tip is to verify your index.php file and .htaccess for unexpected redirects that might be interfering. Sometimes conflicts emerge from server-side settings. Worth a check!
I’m curious, have you considered inspecting the network requests using the browser’s developer tools? it can help in identifying what’s really causing the redirect. Also, any chance you might be using custom headers that Magento isn’t recognizing? Sometimes they can be iffy, affecting POST requests. What other debugging have you tried?
From my experience, this issue can sometimes be caused by unintended redirects in di.xml. Ensure that no plugins or observers are altering the redirect behavior inadvertently. Additionally, ensure that your controller file has implemented the \Magento\Framework\App\Action\Action class and that your execute method is correctly processing and returning the action result. You might also need to verify Magento’s base URL settings, to confirm that there are no misconfigurations leading to unintended route handling.
