I have a list Joomla! form field in my XML, it works in the back end, I can change the dropdown. When saved, the item stays the same.

When I print_r($params)

The value is outputted as "true" and not the value sometimes it appears as 1, no matter which option I choose.

If I change the PHP I obtain a

What could cause this given the option is selected correctly when I view it in the back end.

XML

 <field name="list" type="list" default="" label="MOD_KOY_YOUR_LOGO_LIST" description=""> <option value="0">MOD_MY_MOD_OPTION_LOGO_ONLY</option> <option value="1">MOD_MY_MOD_OPTION_TEXT_ONLY</option> <option value="2">MOD_MY_MOD_OPTION_TEXT_AND_LOGO</option> </field>

Could it be possible that my use of multiple showon= are causing the issue? all seem to work correctly, but some are nested. By nested I mean if a = 1, then show b. If b = 1 then show c.

I worked out that I needed to ensure my output was a number as opposed to true/false or 0/1 etc (boolean).

The way I did this was to set it as intval

$list= intval($params['list']);

Then I can call $list in my if statement and it will perform correctly.

Hope this helps someone else in the future if there's a better way please comment.
