I'm using the AJAX form example for Freeform Pro as described here; https://solspace.com/docs/freeform/form/#ajax_validation

However, the error messages are not very useful and simply say "Required field missing input". Does anyone know if there is a simple way to customise these for each field?

I'm thinking this is perhaps more something in javascript than the module itself.

I also have prevent duplicates switched on for the email address, so I would need to ensure there is still an error for the duplicate along with email errors such as "Please enter your email address" or "Please enter a valid email address".

Thanks, Neil

Becaus its late in the day processing wise (AJAX and all). It's not exactly fluid, for me I've previously had to do this by passing the error strings through a function that does a stripos for known messages (you know the field and the message) and swaps them around...

function reformat_errors(i, items){
  var outErr = "";
  //field switch, add more fields in the switch below
  //and add a function to rewrite the messages
  switch (i) {
    case 'emailField':
    case 'emailConfirmField':
      if ( $.isArray(items) ) {
        for ( var c = 0; c < item.count; c++ ) {
          outErr += reformat_errors_emailField(items[c]);
      } else {
        outErr += reformat_errors_emailField(items);
  return outErr;

function reformat_errors_emailField(item){
  var test = item.toLowerCase();
  //add an elseif condition for each message to catch
  if ( test.indexOf("required field missing input") >= 0 ) {
    return "Please enter an Email Address";
  } else if (test.indexOf("does not match") >= 0 ) {
    return "This email address does not match the previous email address"
  } else {
    return item;

if (data.success == false)
  $.each(data.errors, function(i, item){
    var $errorHolder = $('[name="' + i + '"]').
    //instead of this, lets reformat errors outself
    //var error = ($.isArray(item) ? item.join('<br/>') : item);

    //does the error holder field exist?
    if ($errorHolder.length > 0)
      $errorHolder.append('<p>' + error + '</p>').show();
    //lets add it to general errors
       $generalErrors.append('<p>' + error + '</p>').show();
else if (data.success)
  window.location.href = data['return_url'];

from the example on SolSpace

I've deliberately written the javascript out in quite a long handed fashion so its clearer whats going on and becuase its untested, you can probably optimise this somewhat!

Perhaps someone has a better answer...
