Amigo de esta forma solo me muestra el problema del indice de idg, te lo muestro.
Código PHP:
<?php
$id = $_GET['id'];
//var_dump($idg);
//$idg = $_POST['idg'];
//$idg = isset($_GET["idg"])? $_GET["idg"]: '';
require ("funciones2.php");
$idc = conectar();
$sql = "SELECT * FROM generos WHERE idg=$idg";
//$sql="SELECT * FROM musica m, generos g WHERE m.idg = g.idg";
$sql = "SELECT * FROM musica WHERE id=$id";
$res = ejecutar($sql,$idc);
$fila = getRegistro ($res);
$sql = "DELETE FROM generos WHERE idg=$idg";
//$sql = "DELETE generos FROM generos g, musica m WHERE g.idg = m.idg";
$sql = "DELETE FROM musica WHERE id=$id";
//$res = ejecutar($sql,$idc);
//$sql = "SELECT * FROM musica WHERE id=$id";
//$res = ejecutar($sql,$idc);
//$fila = getRegistro ($res);
//$sql = "DELETE FROM musica WHERE id=$id";
$res = ejecutar($sql,$idc);
?>
