Hey guys,
I have a page with a FormIt form on it. I have some JS to set the value of a form element, and I think that the value really is correctly set, because DOM inspection tools show the desired value with respect to the form element.
When I inspect the page's source code at the same time, however, the supposedly injected value doesn't show up, and my attempt to get the value for post-submit processing with the FormIt hook fails.
Why is that?
Thanks a lot!

The page source code shows what got loaded initially, and the value wasn't loaded until later via javascript.
Try just putting an echo of the $_POST in the hook, and see what is getting submitted.
echo "<pre>";
print_r($_POST);
echo "</pre>";
Yeah, that really seems to be the case. Note, though, that I can't just put the echo(); into the hook as it doesn't output anything. There is the possibility of using MODx's log, but putting print_r($_POST) into the log just outputs '1'.
In any case, it seems I have to somehow make FormIt realize the newly loaded value.
What would I have to do to reach that goal?
Thanks again! It is much learning when you're new to something, so I appreciate your patience

It should accept the value, if the javascript is setting a value. Maybe you can just use a resource with a snippet to read back the POST as the action of the form, to make sure that it is indeed getting set.
Thanks! I succeeded in having "print_r($_POST)" in a snippet that I used as FormIt hook.
I stumbled into something - potentially revealing. There is no value for the field I tried to set at all, but then, there isn't even the corresponding key! Can it be that...
...
an input of type "button" does not add a field to the form it is used in, while an input of type "submit" does?

That was it!
Thanks for the assistance, Susan!
I am not going to try to carry form data from an input of type button again...
Cheers!
