Hi all,

I'm trying to create a custom button that uploads a contact's details to Constant Contact from within the contact page layout.

I can currently upload mass contacts to Constant Contact from a contact list view by using the 'Constant Contact for SalesForce' package (1.6.2). This process involves check-boxing beside any number of contacts in a list, and then adding them to the upload to Constant Contact wizard, which takes care of the rest of the work (onclick Java):

var contactIds = {!GETRECORDIDS($ObjectType.Contact)};

if (!contactIds || contactIds.length < 1) {
alert('Please select at least one Contact to upload.');
} else {
var baseUrl;

var hostnameParts = location.hostname.split('.');
if (hostnameParts[0] == 'ctct2') {
baseUrl = 'https://ctct2.' + hostnameParts[1] + '.visual.force.com';
} else {
baseUrl = 'https://ctct2.' + hostnameParts[0] + '.visual.force.com';
}

var form = document.createElement('form');
form.action = baseUrl + '/apex/UploadWizardStep1';
form.method = 'post';

var hiddenTypeField = document.createElement('input');
hiddenTypeField.id = 'type';
hiddenTypeField.name = 'type';
hiddenTypeField.type = 'hidden';
hiddenTypeField.value = 'Contact';
form.appendChild(hiddenTypeField);

var hiddenUploadIdsField = document.createElement('input');
hiddenUploadIdsField.id = 'uploadIds';
hiddenUploadIdsField.name = 'uploadIds';
hiddenUploadIdsField.type = 'hidden';
hiddenUploadIdsField.value = contactIds;
form.appendChild(hiddenUploadIdsField);

document.body.appendChild(form);

form.submit();
}

However, I want to just add one contact to the upload wizard through process of a custom button on the contact page layout. Any help greatly appreciated.
