Registro usuarios usando Jquery + Ajax

[bestworldhouse]

Hola a todos, estoy haciendo un registro de usuarios pero el problema es que no se donde falla, no me registra ningún usuario en la BD,

index.php

Código:

<form id="form1" action="" method="post"> 
	<fieldset>
		<label for="name">Nombre</label>
		<input type="text" name="name" id="name" class="text ui-widget-content ui-corner-all" />
		<label for="email">Email</label>
		<input type="text" name="email" id="email" value="" class="text ui-widget-content ui-corner-all" />
		<label for="password">Password</label>
		<input type="password" name="password" id="password" value="" class="text ui-widget-content ui-corner-all" />
		<label for="password2">Repite Password</label>
		<input type="password" name="password2" id="password2" value="" class="text ui-widget-content ui-corner-all" />
		
		<input type="submit" name="mysubmit" value="Enviar" />
	</fieldset>
	</form>

un parte de registro.js

Código:

$("#dialog-form").dialog({
            autoOpen: false,
            height: 400,
            width: 350,
            modal: true,
            buttons: {
                'Create an account': function() {
                    var bValid = true;
                    allFields.removeClass('ui-state-error');
                    
                    bValid = bValid && checkLength(name,"username",3,16);
                    bValid = bValid && checkLength(email,"email",6,80);
                    bValid = bValid && comparison(password,password2);
                    bValid = bValid && checkRegexp(name,/^[a-z]([0-9a-z_])+$/i,"Username may consist of a-z, 0-9, underscores, begin with a letter.");

                            $('#form').submit(function() {
                    
                        $.ajax({
                        type: 'POST',
                        url: "validaRegistro.php",
                        data: $(this).serialize(),
                        success: function(){
                            alert("guardado");
                            }
                        });       
                    return false;
                    }); 
                        
                        $(this).dialog('close');
                    }
                    
                    
                    
                    
                },
                Cancel: function() {
                    $(this).dialog('close');
                }
            },
            close: function() {
                allFields.val('').removeClass('ui-state-error');
            }
        });

¿Que es lo que me falta? o ¿donde me falla? , el url: "validaRegistro.php", no creo que haya problema en el archivo...


Muchas gracias de antemano.
Saludos.
