[pmwiki-users] (:input default source=...:) not using $DefaultUnsetPageTextVars?...

[Petko Yotov]

Thanks for the report.

Indeed,  (:input default source=...:) does not currently work with  
$DefaultUnsetPageTextVars and $DefaultEmptyPageTextVars.

These 2 variables work the normal way PmWiki retrieves the value of a 
page text variable, by page and variable name.

The (:input default source=...:) works the other way around, it 
retrieves all existing page text variables from the source page, and 
adds them to the $InputValues array. It doesn't request individual 
variables that can be intercepted and defined when unset or empty.

One difficulty to add the $DefaultUnsetPageTextVars entries to the 
$InputValues array is the former may contain wildcard characters like ? 
or *, and the latter need to be precisely defined / fixed.

I have added non-wildcard entries from $DefaultUnsetPageTextVars and 
$DefaultEmptyPageTextVars to unset or empty entries of the $InputValues 
array. This should be available for 2.3.9 next month.

You can download a nightly release, or a partial export from:

(Only the file scripts/forms.php changed.)

If you do test it, please report if something is not right.

Petko
