How to use Formitretriever without redirect (using custom redirect hook instead)

Hi

I have a multipage form. I want to direct to a page based on a value of a field from the first form. So I ditched redirect and wrote a little custom hook using

$url = $modx->makeUrl($nextpage);
$modx->sendRedirect($url);

which works just fine, except that Formretriever only seems to retrieve stored data if redirect is used. If redirect is used, the values from form 1 are transferred but redirects to a single fixed page in redirectTo. But if redirect isn't used and I use my little snippet instead, no values are retrieved.

Any ideas what I can do? Seems odd that Formitretriever is so tightly linked to redirect.

thanks

I can see that's maybe a bit simple. Now I have a snippet called altRedirect:

$nextpage = $hook->getValue('number-required');
$modx->setPlaceholder('gotopage', $nextpage);
return true;

And the Formit call:

[[!FormIt?
&hooks=`FormItSaveForm,altRedirect,redirect`
&validate=`number-required:required:minLength=`1``
&store=`1` 
&redirectTo=`[[+gotopage]]`
&submitVar=`go`
]]

But doesn't work. When I look at the log it says:

`[[+gotopage]]` is not a valid integer and may not be passed to makeUrl()

When I write the variable and the placeholder to the log it says:

nextpage variable is: 45
placeholder, ie gotopage, is: 0

So is this line in the snippet, $modx->setPlaceholder('gotopage', $nextpage);, incorrect?

Ok, I'm sure this is nearly cracked, except for the return from the snippet to the redirectTo. If "`[[+gotopage]]` is not a valid integer.." then this means that redirect is just looking at a string of letters, rather than a number. How difficult can it be to pass the number from the snippet to the redirectTo?

Stuck. Help, someone.

The problem seems to be returning the value from the snippet. I now have:

$nextpage = $hook->getValue('number-required');
if ( $nextpage == 3 ) {
  $nextpage = $nextpage + 29;
} 
else {
  $nextpage = $nextpage + 41;
}
$modx->log(modX::LOG_LEVEL_ERROR, 'nextpage is: '.print_r($nextpage,true));
$hook->setValues(array(
    'gotopage' => $nextpage
));

return true;

and

[[!FormIt?
&hooks=`altRedirect,redirect`
&validate=`number-required:required:minLength=`1``
&store=`1` 
&redirectTo=`[[+gotopage]]`
&submitVar=`go`
]]

If I dump $hook to the log, it returns "[redirectTo] => [[+gotopage]]" and the log also says "`[[+gotopage]]` is not a valid integer and may not be passed to makeUrl()"

Must be some PHP thing I'm not getting. It all looks a simple thing to but I can't get it to return a value to redirectTo

Hmmm. So Formit accepts other values from the custom hook, but *not* redirect. Here's the snippet now (as simple as I can make it)

$datestamp = date('Y-m-d H:i:s');
$nextpage = $hook->getValue('number-required');
$recipient = $hook->getValue('email');
$hook->setValue('datestamp_submitted', $datestamp);
$hook->setValue('email_address', $recipient);
$hook->setValue('gotopage', $nextpage);
$modx->log(modX::LOG_LEVEL_ERROR, 'pageid is: '.print_r($nextpage,true));
return true;

Formit:

[[!FormIt?
&hooks=`altRedirect,email,redirect`
&validate=`number-required:required:minLength=`1``
&store=`1` 
&emailTpl=`emailTpl` 	
&emailTo=`[[+email_address]]` 	
&emailSubject=`Test Form`
&redirectTo=`[[+gotopage]]`
&submitVar=`go`
]]

Email Tpl:

<p>Hello [[+firstname]]</p>
Page: [[+gotopage]]<br />
Email: [[+email_address]]<br />
Phone: [[+telephone]]<br />
Day: [[+datestamp_submitted]]

The email is duly sent to [[+email_address]] and in the email, [[+gotopage]] is replaced by an integer. But the form refuses to redirect to this integer because, in the log, it says, again, "..`[[+gotopage]]` is not a valid integer and may not be passed to makeUrl()"

Why not? Why isn't +gotopage an integer when it returns to Formit? I confess I have no earthly idea. Can someone point to the error in my code?
