The built-in <MTElse> tag only works with built-in conditional tags such as MTEntryIfExtended. It does not work with plugin conditional tags, such as MTEntryIfComments. This hack modifies MovableType to support MTElse in any conditional plugin tag.

lib/MT/Builder.pm Modification

Go to your MovableType installation directory, and open the file Builder.pm in the lib/MT subdirectory.

1. Find the line (line 98 in MT 2.63) that says:

               my($tokens, $uncompiled);

   and add the following line after it:

               my $tokens_else;

2. Find the line that says:

                       $tokens = [ grep $_->[0] ne 'Else', @{ $t->[2] } ];

   and add the following line after it:

                       $tokens_else = [ grep $_->[0] eq 'Else', @{ $t->[2] } ];

3. Find the line that says:

                   $ctx->stash('tokens', $tokens);

   and add the following line after it:

                   $ctx->stash('tokens_else', $tokens_else);

lib/MT/Template/Context.pm modification

Go to your MovableType installation directory, and open the file Context.pm in the lib/MT/Template subdirectory.

1. Find the section (line 43 in MT 2.63) that says:

           if ($condition->(@_)) {
               return _hdlr_pass_tokens(@_);
           } else {
               return '';
           }

   and replace it with the following section:

           if ($condition->(@_)) {
               return _hdlr_pass_tokens(@_);
           } else {
               my($ctx, $args, $cond) = @_;
               return $ctx->stash('builder')->build($ctx, $ctx->stash('tokens_else'), $cond);
           }
