I would suggest to use the jQuery $.ajax function. If tyou have a look
at the plugin 'coordinates':
There is the x_*.php file that in your case is the 'digitizepoints.php'.
The url used in the ajax call is to this file
var digitizeUrl = PM_PLUGIN_LOCATION +
'/digitizepoints/digitizepoints.php?lon=' + px + "&lat=" + py + ....;
All the values from the form have to be placed in the request in
addition to the parameters that you use already (lon, lat, __action).
Instead of adding everything to the url query part you can also use the
parameters array for the ajax call. See the jquery docs, they're quite good.
Reading the form values and transforming them to key=value list can e.g.
be done via the function in pm.form.js
PM.Form.getFormKVP()
returns everything in a string ready for URL concatenation, like
"&key1=value1&key2=value2..."
or
PM.Form.getFormKvpObjAll()
that returns everything in object/array notation, like {key1: value1,
key2: value2,...}.
The return value to be inserted can be already plain HTML created by the
PHP, then you need to specify this in the ajax call as
dataType: "html",
a sample part for the ajax would be
$.ajax({
url: digitizeUrl,
dataType: "html",
success: function(response){
$('#containerWhereTodisplayHtml').html(response);

Yes, please do so, e.g. below the part
http://svn.pmapper.net/trac/wiki/FaqCustomizations
and creating a new paragraph like "using p.mapper dialogs with
createDnRDlg"
