[Solved] ExtJS Checkbox - how to store 'unchecked' value in db?

I’m attempting my first CMP and thought I was doing well until I wanted to save a false value from a checkbox type field.

Checking it works fine, returning the value ’1’ and saving it to the db.

However, the checkbox mimics html checkbox behaviour in not returning a value when unchecked. In this case I need a value ’0’ to save into my database. Any ideas how to go about this?

{
    xtype: 'checkbox'
    ,fieldLabel: _('active')
    ,name: 'active'
    ,inputValue: '1'
}

ps. I’ve used the ’combo-boolean’ type for now which works fine, but I would prefer to have the checkbox working!

There is no convenience parameter or method to send an unchecked checkbox value with Ext 3.3 (Ext 4.0, on the other hand, has a dandy parameter called [tt]uncheckedValue[/tt]).

Here’s an older thread in Sencha’s forums that talks about using a hidden field to send a value depending on checked state:

Hope this helps

Hi, thanks for the link - I’d seen some discussion on Sencha but hadn’t stumbled on a solution. I’m really not familiar with ExtJS but will have a crack at that suggestion!

I thought when browsing the code of 2.1-rc4 the other day there was some extension there that would force 0 to be sent when not checked, but not 100% sure on that. Was looking for something else.

Anyway, I think the answer would be in your processor where you actually use the data (or lack thereof) to store in the db.

It should be sending an empty key to your processor file, and you can use that to check it. Even better, use a syntax like this:

$active = $modx->getOption('active',$scriptProperties,0);

Yes, we added an xtype: ’xcheckbox’ that behaves exactly like a normal checkbox, except it sends 0 if unchecked.

Very nice, just got stuck on this too and xcheckbox saved my bacon. No seriously, I'm cooking bacon right now.
