[pmwiki-users] PmForm - change summary and cancel button

[Randy Brown]

Dave,

Thanks for your pointers. The BlogIt recipe was a bit complex for me. I think I'm missing a couple of very basic things:

1. My function doesn't seem to be invoked. How does my HandleActions function get called? If it's called, will PmForm still do its part, or will I now have to update *all* the fields myself? Would I be better off just making a custom version of PmForm?

2. My posting template ("metapost") only lists the page text variables. Should it list the EnteredChangeSummary too? When I tried that, PmForm created a page text variable by that name - not what I wanted. How will I pass EnteredChangeSummary to the handler?

Thanks,

Randy

P.S. Here is what is now in my config:

$PmForm['savemeta'] = 'saveto={$FullName} form=#metaform fmt=#metapost';

## Allow PmForms to change the page summary
SDV($HandleActions['MetaEdit'], 'HandleMetaEdit'); 
SDV($HandleAuth['MetaEdit'], 'edit');

# ----------------------------------------
# - HandleActions Functions
# ----------------------------------------
function HandleMetaEdit($pagename, $auth='edit') {  
global $_POST,$ChangeSummary;
   echo "HandleMetaEdit: entering function";  # This never appears
    if (isset($_REQUEST['cancel'])) {
            Redirect($pagename);
    }
    Lock(2);
    if (!PageExists($pagename)) {
            Abort("HandleMetaEdit: source page ($pagename) doesn't exist");
    }
    if ($_POST['target']=='savemeta' && @$_POST['save']) {
             $ChangeSummary = $_POST['EnteredChangeSummary'];
	     $old = RetrieveAuthPage($pagename, $auth, TRUE);
     	     if (!$old) {
                    Abort("HandleMetaEdit: cannot read source ($pagename)");
             } else {
	            $new = $old;
	 	    $new['csum'] = $ChangeSummary;  
                    # Do I need to handle the other fields, or will PmForm continue to do that?
		    UpdatePage($pagename,$old,$new); 
	     }
      }
      Lock(0);
}

In my markup:

[[#metaform]]
**Edit the information about this page**
(:input pmform target=savemeta:)
(:input default source={*$FullName} request=1 :)
(:messages:)
(:table:)
etc.
**Please summarize your changes:** \\
(:input text EnteredChangeSummary size=80:)\\ \\

[[#metapost]]
(:template defaults savevars=$:OnePTV,$:AnotherPTV, etc.  :)
[[#metapostend]]
