OK, in order to resolve this, you need jQuery 1.7.x+ and the SPServices jQuery library version 0.7.2 or greater installed on your site.
Use GetListItems as the operation from SPServices.
I'm searching for pages within the Pages directory, so listName is "Pages".
The CAML View Fields are basically the columns for PublishingContactEmail and PublishingContact. I found those using u2u's CAML builder version 4.0.0.0
The ows_ variables can be found in the xml view of the POST object in firebug.
The ows_PublishingContact returns a long nasty string of the contact's information. Fortunately the email address is surrounded by ,#
, which made splitting it into an array and then searching for an email @ easy, but that's why that's there.
function get_page_contact_email() {
var thisPageID = _spPageContextInfo.pageItemId;
var e;
$().SPServices({
operation: "GetListItems",
async: false,
listName: "Pages",
CAMLViewFields: "<ViewFields><FieldRef Name='PublishingContactEmail' /><FieldRef Name='PublishingContact' /></ViewFields>",
CAMLQueryOptions: "<QueryOptions><ExpandUserField>True</ExpandUserField></QueryOptions>",
completefunc: function (xData, Status) {
$(xData.responseXML).SPFilterNode("z:row").each(function () {
if (thisPageID == $(this).attr("ows_ID")) {
if ($(this).attr("ows_PublishingContactEmail")) { // if page email is set
e = $(this).attr("ows_PublishingContactEmail");
} else if ($(this).attr("ows_PublishingContact")) { //otherwise use contact info
var contact = $(this).attr("ows_PublishingContact").split(",#");
for (var c = 0; c < contact.length; c++) {
if (contact[c].indexOf("@") != -1) {
e = contact[c];
}
}
} else { //or nothing is set.
e = false;
}
}
});
}
});
return e;
}
