send variable to function() before send form

I have two inputs at my FORM:

$_siape and
$_data_nasc

before sending the form, I would like it to run a function that checks if the value of these two fields are correct.
see a little of my script for run before sending form:


require_once('lib/nusoap.php');
function validarProfessor($_siape=NULL,$_data_nasc=NULL,&$_resposta){
$_retorna = FALSE;

if (!is_null($_siape) AND !is_null($_data_nasc)){
if (($_data_nasc{2}=="/")AND($_data_nasc{5}=="/")AND(strlen($_data_nasc)==10)){
list($_dia, $_mes, $_ano) = explode('/', $_data_nasc);
if (!checkdate(intval($_mes),intval($_dia),intval($_ano))) {
$_resposta = "Data inválida!";
return $_retorna;
}
$_data_nasc = $_ano."-".$_mes."-".$_dia;
}elseif (($_data_nasc{4}=="-")AND($_data_nasc{7}=="-")AND(strlen($_data_nasc)==10)){
list($_ano, $_mes, $_dia) = explode('-', $_data_nasc);
if (!checkdate(intval($_mes),intval($_dia),intval($_ano))) {
$_resposta = "Data inválida!";
return $_retorna;
}
$_data_nasc = $_ano."-".$_mes."-".$_dia;
}else{
$_resposta = "Formato inválido de data (esperado dd/mm/aaaa)!";
return $_retorna;
}
}else{
$_resposta = "Faltando parâmetros obrigatórios!";
return $_retorna;
}
$cliente = new SoapClient("http://XXXXX?wsdl",true);
//$cliente->setCredentials("XXX","XXX",'XXX');
$cliente->setCredentials("XXX","XXX",'XXX');
$erro = $cliente->getError();
if ($erro) {
$_resposta = $erro;
}
$result = $cliente->call('isProfessorAtivoBySiape', array($_siape,$_data_nasc));
if ($cliente->fault){
$_resposta = $result;
}else{
$erro = $cliente->getError();
if ($erro){
$_resposta = $erro;
}else{
$_retorna = (strtoupper($result)=='TRUE')?TRUE:FALSE;
}
}

return $_retorna;
}
?>

Hi osnysantos,

You can't run PHP on the client side (i.e. in the form). You can either set this up as server side validation; or re-write it in JavaScript to run from the client side.

The 'required' and 'date' validations can probably be done with the exisiting ChronoForms validation - with maybe a new validator.

The Soap validation would presumably need to be written in AJAX???

there is not enough to do with js. because he seeks in a database ... to whether or not there is the teacher.
this is possible?

Hi osnysantos,

Yes it is possible - that's the AJAX bit. But I am no expert, just a starter with that.
