How Can I Submit Data from Hidden Form Fields in a Web Form?

Submit Hidden Form Fields

In a complex web form, it's often necessary to hide portions of the form based on user interaction. This dilemma arises when attempting to submit data from hidden fields, as browsers typically only submit fields that are visible on the page, ignoring those styled with "display:none."

Solution:

While "display:none" prevents fields from being submitted, using "visibility:hidden" and "position:absolute" allows fields to remain hidden while still being included in the form submission.

.hidden {
  visibility: hidden;
  position: absolute;
}

By setting "visibility:hidden," the fields are effectively hidden from the user without affecting their submission. Additionally, "position:absolute" helps maintain the original visual layout.

Alternative Approach:

If the visual effect is not crucial, consider an alternative approach that avoids the issue altogether.

1. Dynamic Form Loading:

Fetch each step of the form asynchronously using AJAX. This way, only the active step will be loaded and visible, eliminating the need to hide other steps.

2. Tabular Form Layout:

Arrange the form fields in a tabular layout, using JavaScript to toggle the visibility of specific rows or columns based on step changes. This approach retains the form's structure and ensures all fields are always present for submission.
