Can't find the specified shape key?

Question

MODX

The site is on ModX, all pages are loaded at once and scrolled through as in a slider - this is how the site is made. Several pages use ajaxForm and the following error occurs on submit:

Cannot find the specified form key

There is an assumption that this is due to the presence of several forms on the page. What else could be the problem, who faced? How can you decide?

Answer 1

Thanks everyone for the helpful advice. The problem in the end was different: the form was connected using markup, bypassing ModX.

Answer 2

AjaxForm is just a wrapper for Formit, look at the last submitVar value, it must be set.

Answer 3

photosho , form submit buttons also need a name attribute equal to submitVar in Formit (AjaxForm).

<form method="post" action="" id="form-1">
  .......
  <input type="submit" name="form1" class="btn" value="Отправить" />
   .............
</form>

<form method="post" action="" id="form-2">
  .......
  <input type="submit" name="form2" class="btn" value="Отправить" />
  .............
</form>

If instead you <input type="submit">use <button type="submit">Отправить</button>, then you can add a hidden field in the form:
<input type="hidden" name="form3" value="1" />

Answer 4

It's even more likely that the problem is that you called the cached AjaxForm. Call with "!":
[[!AjaxForm?....
or
{'!AjaxForm' | snippet : [...]}
Because multiple forms without any submitVar work just fine with AjaxForm.
