[Phpwebsite-developers] Fallout Settings class - text strings

[Verdon V. <ve...@ve...>]

Hi :)

I am working on my first mod for phpws 1.x. My module has some  
settings that are text strings. I don't seem to be able to set these  
to NULL or empty strings. For example, by default, these settings  
should return NULL. What they are returning is 0. Maybe I'm  
misunderstanding, but I don't think 0 is the same as NULL in this  
instance.

I have tried in my inc/settings.php setting them as

$settings['custom_1_label'] = NULL;

and as

$settings['custom_1_label'] = '';

In either case, when I bring these values up in a settings edit form  
in this manner,

$form->addText('custom_1_label', PHPWS_Settings::get('ssclassifieds',  
'custom_1_label'));
$form->setSize('custom_1_label', 40, 255);
$form->setLabel('custom_1_label', _('Custom field 1 label'));

The form will have a 0 in the field. If I remove the zero, and save  
the settings, and then bring up the edit screen again, the 0 is back.

Is this normal behaviour? If it is, I can likely work with it, but it  
would be more familiar to me if the setting contained NULL or an  
empty string.

Thanks for any input into this and very  best regards,
