Como restringir valoración por imagen y dia tengo esta tabla:
Código PHP:
CREATE TABLE IF NOT EXISTS `ip_votos` (
`id` int(3) NOT NULL auto_increment,
`ip` varchar(16) NOT NULL,
`id_imagen` int(4) NOT NULL,
`date` varchar(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=0 ;
Código PHP:
<?php require("config.php");
//conecta con la base de datos
@mysql_connect($db_server,$db_user,$db_password) or die("No pudo conectarse con la base de datos del servidor. Compruebe las variables \$db_server, \$db_user y \$db_password en config.php");
@mysql_select_db($db_name) or die("La selección de la base de datos ha fallado. Compruebe la variable \$db_name en config.php");
//actualiza votos
$id = $_POST["id"];
$vote = $_POST["vote"];
//IP

//a partir de aqui es lo que he puesto para la Restriccion de IP
$sqls = @mysql_query("SELECT COUNT(*) FROM $db_ip_votos WHERE ip=$ip AND id_imagen={$_POST["id"]} AND date=$fecha");
$resultado=mysql_query($sqls) or die (mysql_error());
if (mysql_result($resultado,0) == 0){
//actualiza los votos en la base de datos
if(isset($id) && isset($vote)){

//registra cada vez que votas una imagen la ip, el id de la imagen y la fecha
