Hi - digging up an old post here - but I have a formit form, which on submit - i redirect to a review page which summarises the form data, on submit click on this 2nd page the form is submitted and the user is moved to a confirmation page. From this 2nd page (the summary of form data), I would like the option for the user to click on a button to go back to the form page to update their form details... How can I do this....??

Michelle84 could you share your solution?

Thank you.
Those are from formit I see.
Ah, redirect happens after store. That explains.
And the first function means that for each user, the data is stored in a unique way, if I understand correct.

Well, that's a relief

I think this two functions should answer your questions:

    /**
     * Gets a unique session-based store key for storing form submissions.
     *
     * @return string
     */
    public function getStoreKey() {
        return $this->modx->context->get('key').'/elements/formit/submission/'.md5(session_id());
    }

    /**
     * Handle post-processing through postHooks
     * @return bool
     */
    public function postProcess() {
        $success = $this->runPostHooks();
        if ($success) {
            /* if store is set for FormItRetriever, store fields here */
            $store = $this->modx->getOption('store',$this->config,false);
            if (!empty($store)) {
                $this->dictionary->store();
            }

            /* if the redirect URL was set, redirect */
            $this->checkForRedirect();

            /* set success placeholder */
            $this->setSuccessMessage();

            /* if clearing fields on success, just end here */
            if ($this->modx->getOption('clearFieldsOnSuccess',$this->config,true)) {
                $this->clearFieldsAtEnd = true;
            }
        }

        return $success;
    }

Wow Bruno, you're so smart !
It's working (not with the validation check, haven't tried that yet).
I'll post the code later on for others who might be interested.

By the way, before I get carried away, is this a good / safe etc. way to do this?
Is it not possible that data from a wrong user gets displayed in the form?

Thanks, I'm going to give it a try.
Why would the redirect hook work, and my own hook not? Doesn't the redirect hook do the same: redirect to another location?

because you're redirecting before formit can store the request, you can't get the datas.

you can try to do the redirection with an additional snippet, placed after formit, not in a formit-hook.
To be sure, the form has validated you can set a placeholder or something in your formit-hook and read that placeholder by your snippet, before redirecting.

Can't modify my post anymore, but form 2 has ID 30, and resource 31 is a thank you page.

Alright, I've been trying something on my own. My idea is to have two submit buttons, and with a custom hook check which one is clicked. Based on that I forward to the previous form page or the next.
Now I want the filled in values to display with formItRetriever, be it going back or forth. It's not working though... I'm going crazy over this ;-)

FORM 1 (ID 22) (this one is just forwarding)

[[!FormIt? &hooks=`redirect` &store=`1` &redirectTo=`30`]]
[[!FormItRetriever]]


	
	
	        Reactie:
	        [[+fi.error.content]]
	    
	    [[!+fi.reactie]]

FORM 2 (back and forth)

[[!FormIt? &hooks=`backOrForward` &store=`1`]]
[[!FormItRetriever]]

  




 Naam: [[+fi.error.naam]]

And the snippet I made (backOrForward):

$modx->log(modX::LOG_LEVEL_ERROR,'START BACK OR F0RWARD');

if (isset($_POST['next'])) {
 $modx->log(modX::LOG_LEVEL_ERROR,'next clicked');
	$url = $modx->makeUrl(31);
	$modx->sendRedirect($url);
} else if (isset($_POST['previous'])) {
 $modx->log(modX::LOG_LEVEL_ERROR,'previous clicked');
	$url = $modx->makeUrl(22);
	$modx->sendRedirect($url);
} else {
 $modx->log(modX::LOG_LEVEL_ERROR,'nothing clicked');
	$url = $modx->makeUrl(100);
	$modx->sendRedirect($url);
}

The back and forth forwarding works, but the values are not stored.

Oh
For everything I need, you seem to have the answer Bruno ;-)
