[pmwiki-devel] fix: forms.php -- select list default on reload

[DaveG]

When the form reads values from a source, and is being reloaded due to 
an entry error, the user values are over-ridden by the values in the 
source file. Thus, select lists return to their original source file 
values, rather than retaining the values selected by the user.

This is the fix for that:

Move this block:
   if (@$args['request']) {
     $req = array_merge($_GET, $_POST);
     foreach($req as $k => $v){
       if (!isset($InputValues[$k]))
         $InputValues[$k] = htmlspecialchars(stripmagic($v), ENT_NOQUOTES);
     }
   }


Below the "if ($source) {" block.

Change the block to read override the source values (isset rather than 
!isset):
   if (@$args['request']) {
     $req = array_merge($_GET, $_POST);
     foreach($req as $k => $v){
       if (isset($InputValues[$k]))
         $InputValues[$k] = htmlspecialchars(stripmagic($v), ENT_NOQUOTES);
     }
   }
