So if you want all your jQuery Validate error messages to appear in one place you would use
http://docs.jquery.com/Plugins/Validation/validate#toptions (Find errorPlacement) option on that page.
I noticed some answers on here answer one but not both options.
1)
That being said if you want custom placement for all of your errors you can do this:
$("#myform").validate({
errorPlacement: function(error, element) {
error.appendTo('#errordiv');
}
});
2)
If you want to specify specific locations for one or multiple error labels you can do this.
errorPlacement: function(error, element) {
if (element.attr("name") == "email" )
error.insertAfter(".some-class");
else if (element.attr("name") == "phone" )
error.insertAfter(".some-other-class");
else
error.insertAfter(element);
}
