Making eForm Work with AjaxSubmit Reliably

eForm plus AjaxSubmit sounds straightforward, but in older projects the combination often fails in messy ways: validation disappears, success output never returns, or the form behaves differently between AJAX and normal

eForm plus AjaxSubmit sounds straightforward, but in older projects the combination often fails in messy ways: validation disappears, success output never returns, or the form behaves differently between AJAX and normal requests.

Why It Happens

  • eForm expects a normal request cycle
  • AjaxSubmit changes how responses are injected back into the page
  • the template may mix cached and uncached output incorrectly

What to Review

  1. keep the form call uncached
  2. check that the returned fragment contains the exact HTML the frontend expects
  3. avoid redirect-oriented thank-you logic in an AJAX-only flow
  4. test validation and success messages separately

Most eForm + AjaxSubmit bugs are not about the mail layer. They come from a mismatch between a synchronous form design and an asynchronous response flow.
