Hi, I've try to use remote method and not work.
There are the parameters <script type="text/javascript"> $(document).ready(function(){ var validator = $("#formcode").validate({ rules: { codigo: { required: true, minlength: 3, remote: "valcodigo.php" } }, errorPlacement: function(error, element) { error.insertAfter(element); }, messages: { codigo: { remote: jQuery.format("El código {0} ya existe") } }, errorClass: "errores" }) }) </script> The form <div id="form"> <form id="formcode" name="formcode" method="post" action="<? echo $PHP_SELF?>?p=<?echo $modulo?>&acc=grabar" class="cmxform"> <fieldset> <label for="codigo">Código</label> <input type="text" name="codigo" id="codigo" class="input" /><br /> </fieldset> <input class="submit" type="submit" value="Grabar" /> </form> The remote script <?php $request = trim(strtolower($_REQUEST['value'])); $codigo= array('A1234','B1234'); $valid = 'true'; foreach($codigo as $cod) { if( strtolower($cod) == $request ) { $valid = 'false'; } } echo $valid; ?> required and minlenght work fine but remote don't I've download the entire "Milk" demo and I've copy it in my local server and remote method don`t work too. Anybody help me??? Thanks Adrian
