Form Validation - Modify Second Parameter

[quote author="Aken" date="1327971366"]Yes, makes sense. You're correct then, it's a variable scope issue. The $param variable is created fresh each time the callback is run, based on the info passed to it in the rule. If you call "callback_valid_address[10]", $param = 10. "callback_valid_address[15]", $param = 15. Etc...

You'll want to use a class property if you want to hold on to the value of a property throughout the class. psychoder gave a good example.[/quote]

Hmm, bummer.

For a little insight, I was hoping to find a cleaner way to implement an address validator which would reach out and grab some addresses from Yahoo/Google. But since I'm really only limited to returning a TRUE/FALSE from the validator, and not easily returning an array of addresses, I'm not sure what else to do.

I currently having it working via two different javascript calls and a few functions in codeigniter. I suppose I should just leave well enough alone, but I know it can be done easier.

For grins 'n giggles, here's what I have so far...

Code:

// Submission of Add or Edit Client Form
  $('#addOrEditClientForm').live('submit', function(e) {

  // set hidden address field value
  $('input[name=address]').val(
   $('input[name=street]').val()+'#'+
   $('input[name=city]').val()+'#'+
   $('input[name=state]').val()+'#'+
   $('input[name=zipcode]').val()
  );
  // set hidden telephone field value
  $('input[name=telephone]').val(
   $('input[name=telephoneA]').val()+'#'+
   $('input[name=telephoneB]').val()+'#'+
   $('input[name=telephoneC]').val()
  );
  // set hidden telephone2 field value
  $('input[name=telephone2]').val(
   $('input[name=telephone2A]').val()+'#'+
   $('input[name=telephone2B]').val()+'#'+
   $('input[name=telephone2C]').val()
  );
  validateAddOrEditClientForm();
  e.preventDefault();
  
});

function validateAddOrEditClientForm() {
// lookup address first before validating rest of form
$('#addOrEditClientBox-loading').fadeIn(
  function(){
   // validate client address
   validateClientAddress(
    // callback function
    function() {
     // continue validating client information
     validateClientInfo();
    }
   ) // end validateClientAddress
  }
); // end fadeIn
}

function validateClientAddress(callback) {
if ($('input[name=address]').val()=='###' || $('input[name=foundAddress]').val()=='true') {
  callback();
} else {
  $.post("validate_clientAddress","address="+$('input[name=address]').val()+"&csrf;_test_name="+$.cookie("csrf_cookie_name"),
   function(data) {
    if (data) {
     if (data=="error") { // no matching addresses, set error and continue validating rest of form
      $('input[name=foundAddress]').val('false');
      callback(); // continue validating rest of form
     }
     else { // found possible matches
      $('body').append(data); // append verifyClientAddressBox to body
    
           // calculate position of box
      var top = parseInt($('#addOrEditClientBox').css('top'))+
           parseInt($('#addOrEditClientBox').css('height'))/2-
           parseInt($('#verifyClientAddressBox').css('height'))/2;
          
      $('#verifyClientAddressBox').css({'top':top}); // set new position
     }
    }
    else callback(); // continue to validate client information if address is fine
   }
  ); // end post
} // end else
}

/**
* Validate Client Info
*
* description
*/
function validateClientInfo() {
$.post("validate_addOrEditClientForm",$('#addOrEditClientForm').serialize(),
  function(data){
  var content = $(data).find('#addOrEditClientForm'); // retrieve just form portion of view
  $('#addOrEditClientBox-loading').fadeIn(
   function(){
    $('#addOrEditClientForm').replaceWith(content);
   }
  );
  $('#addOrEditClientBox-loading').fadeOut();
  }
); // end $.post()
}

Code:

public function validate_clientAddress() {

  $value = strtolower($this->input->post('address'));
  
  $address = explode("#",$value);
  $address = array_filter($address);
  $addressURL = urlencode(implode(', ', $address));

  // retrieves array of addresses from Yahoo
  $addressData = file_get_contents('http://where.yahooapis.com/geocode?location='.$addressURL.'&flags=J');
  $addressData = json_decode($addressData);
  
  // determine if addresses found
  if ($addressData && $addressData->ResultSet && $addressData->ResultSet->Error == '0' && $addressData->ResultSet->Found) {
   for ($i=0; $i<$addressData->ResultSet->Found; $i++) {
    $addresses[$i]->house = trim($addressData->ResultSet->Results[$i]->house);
    $addresses[$i]->street = trim($addressData->ResultSet->Results[$i]->house.' '.$addressData->ResultSet->Results[$i]->street);
    $addresses[$i]->city = trim($addressData->ResultSet->Results[$i]->city);
    $addresses[$i]->state = trim($addressData->ResultSet->Results[$i]->statecode);
    $addresses[$i]->zipcode = trim($addressData->ResultSet->Results[$i]->uzip);
    
    if ($i==3) break; // limit to only 4 total results returned
   }
  } else {echo 'error'; return;} // if not found, give an error
  
  // make sure full match found, not partial
  if ($addresses[0]->house=="" || // don't allow missing street number from matches
    $addresses[0]->street=="" ||
    $addresses[0]->city=="" ||
    $addresses[0]->state=="" ||
    $addresses[0]->zipcode=="")
  {echo 'error'; return;}; // if not found, give an error
  
  if (count($address)==4) {
   if (strtolower($addresses[0]->street)==$address[0] &&
     strtolower($addresses[0]->city)==$address[1] &&
     strtolower($addresses[0]->state)==$address[2] &&
     strtolower($addresses[0]->zipcode)==$address[3])
   {echo $addresses[0]->street.'#'.$addresses[0]->city.'#'.$addresses[0]->state.'#'.$addresses[0]->zipcode; return;}
  }
  
  $data['addresses'] = $addresses;
  $this->load->view('partials/clients/verifyClientAddressBox',$data);
  
  return;
}
