Residual data problem

Hello:

I have a multiple page form. In the first page the user selects from a drop-down (created from a SQL consult/Custom Element) and that creates a link that allows the user to select some more info and then proceed to the next page. However, if i go back using the back arrow of the browser or after the user submits, some information is left in the first page. Also the Custom element changes from this:

<select id="province" class="" name="province" size="1">

    <option value="--"></option>
    <option value="AB"></option>

</select>

to this

<select class="" id="province" size="1" name="province">

<option value="">Please select a province</option>
<option value="">
AB  -  Alberta</option>
</select>

I tried deactivating the site cache, but it didn't work. Also tried using javascript

$('form').each(function() {this.reset()});
 window.location.reload(true);
 document.getElementById("chronoform_nomination-S").reset();

with various results, none effective.

I thought it had to do with the cf_sid variable not updating properly but i checked and it is changing with every refresh. Tried to clear the cache (ctrl+F5) but didn't work either. and also with the JAT3 Clean Cache plugin.

The form itself is working fine except for that not so little problem. Thanks

Hi oneira,

I'm not sure why your custom code is breaking but it may be because you are using -- as a value or because there is no text in the options.

You should also check that you have a Session to Data action with Clear Data set to yes in the final form event.

Well i checked and the changes are made automatically. That is, the first time i load the form it shows me the first code

<select id="province" class="" name="province" size="1">

    <option value="--"></option>
    <option value="AB"></option>

</select>

Which is working fine, and as i said, is generated in a Custom Element from a SQL query. However if i go to the second page and then go back using the browser back arrow, It will show the second code

<select class="" id="province" size="1" name="province">
<option value="">Please select a province</option>
<option value="">
AB  -  Alberta</option>
</select>

And as far as i know, that is not being generated from a Custom Element but probably from a cache file, or something. As i said before, i've tried every option to clean the cache but to no avail.

I followed the tutorial provided here

http://www.chronoengine.com/faqs/57-cfv4/cfv4-actions/2658-how-can-i-create-a-multi-page-form.html

and in my current list of events i dont have a Session to data, although the problem is not when the user submits the form but when he/she reloads the first page.

Thanks

Update: i found a post that suggested using this code

$session = JFactory::getSession(); $session->clear('user');

and it's kind of working.

I have tested the following scenarios:
Scenario 1
1. the user access the form
2. selects and goes to page 2
3. goes back to page 1 using the navigation buttons on the browser
4. selects another value and goes to page 2

Scenario 2:
1. the user access the form
2. selects and goes to page 2
3. goes back to page 1 using the navigation buttons on the browser
4. reloads the page

The scenario 1 is working and the scenario 2 is not. I tried using the Session to Data but it didn't work.

Thanks

Hi oneira,

Sorry, I have no idea what is happening here. What you describe doesn't make sense to me :-(

Bob

i think i made it work.
i used this code

$app = JFactory::getApplication('site',array('session'=>false));
unset($form->data);
$session = JFactory::getSession();
$session->clear('user');

as suggested in this post and it worked!

However, I'm not exactly sure what happened, because the two lines do two different things: one clears the Joomla Session for the guest user, and the second one unsets the values. So, i would kindly suggests that you guys check this one out so it can be labeled as a bug, glitch, or simply config error. Thanks

Hi oneira,

I still have no idea what the problem is that you have solved :-( Hard to know if there is any bug or not - I rather think not.

Be careful clearing the User session as that will affect the whole Joomla! session, not just ChronoForms.
