用PHP删除行的问题

问题描述：

I'm trying to remove a row from a table with php. I have the following piece of code:

<?php
   if($_GET["act"] == 'eliminarart' && $_GET["id"] != '')
   {
       var_dump($_GET);
       if($mysql->query("DELETE FROM landing_articulos WHERE id_articulo = ". intval($_GET["id"])." LIMIT 1")){
           redirige('nuevapagina.php');
       } else {
           $e=$mysqli->error;
           echo $e;
       }
   }
?>

<head>
    <script language="javascript">
        function eliminar_art(id){
            var mensaje = 'Deseas eliminar este articulo?';
            eliminar = confirm(mensaje);
            if (eliminar)
                document.location='nuevapagina.php?act=eliminarart&id='+id;
        }
    </script>
</head>

I call all this code here:

while($f1 = mysql_fetch_array($c1)){
    ?>
    <div style="float:left; width:32%; padding-left:0px; color:#ef5000; font-weight:bold; margin:5px;"><p><a href="http://www.certifacil.es/articulos/<?=$f1["url"]?>" target="_blank"><strong><?=$f1["nombre"];?></strong></a> <a href="editar_nuevapagina.php?id=<?=$f1["id_articulo"]?>"><img src="imagenes/lapiz.png" width="15" height="15" border="0"/></a> </a> <a href="javascript:eliminar_art('<?=$f1["id_articulo"]?>');"><img src="imagenes/delete.png" width="15" height="15" border="0"/></a> <? if($f1["valido"]=='0')echo ' - SIN VALIDAR';?></p></div><?
}

The var_dump returns data, although the id I get is a string instead of an int as it's defined in the database. So what I am doing wrong? All this code is in a page called nuevapagina.php.

答

no need to convert into integer just simply do it as:

$mysql->query("DELETE FROM landing_articulos WHERE id_articulo = ".$_GET["id"]." LIMIT 1"
