How to Send Values from Multiple Forms in a Foreach Loop Using AJAX in Laravel

Handling multiple forms efficiently within a single view can often lead to confusion and errors. One common issue arises when trying to process multiple forms created within a foreach loop in Laravel.

The Problem

When using Laravel, many developers encounter the problem of submitting multiple forms that only send the data from the first one. This occurs because the HTML id attributes must be unique, and reusing the same id leads to unexpected behavior when trying to access the form data with JavaScript or AJAX.

In this guide, we’ll explore how to properly set up your forms and AJAX calls to ensure each one sends its own data to the controller correctly.

Understanding the Blade Template

When you generate forms in a loop in your Blade template, it might look something like this:

Conclusion

In conclusion, by changing from an id to a class for your form elements and adjusting your AJAX calls accordingly, you can successfully send distinct values from multiple forms in a foreach loop to your Laravel controller. This approach ensures that each form submits its respective data without conflict.

Now you can smoothly interact with multiple forms on your Laravel application, providing a seamless user experience!
