How Can I Ensure Hidden Form Fields Are Submitted in Multi-Step Forms?

Hidden Form Field Submission with CSS Display

When dealing with complex forms divided into multiple steps, it's common to control visibility using CSS display properties. While hiding form elements with display:none prevents their submission, this post explores a solution to this issue.

Problem:

In a multi-step form where steps are hidden using display:none, submitting the form only captures fields within visible elements. Hidden fields are ignored.

Solution:

Instead of using display:none, set hidden form elements to visibility:hidden and position:absolute. This combination allows the fields to be hidden visually while still submitting their values along with the form.

Updated Note:

As of November 2015, it's no longer necessary to use the above solution as current browsers automatically submit fields even when hidden using display:none. However, disabling fields using the disabled attribute will continue to prevent their submission.
