Hola helthon ...
Si quieres que te muestre el resultado de tu busqueda en la BD de acuerdo a la opcion lo puedes hacer con capas y javascript... aqui te mando un ejemplo..
capas.php Código PHP:
<html>
<body>
<SCRIPT LANGUAGE="JavaScript">
<!--
function showdiv(pass) {
var divs = document.getElementsByTagName('div');
for(i=0;i<divs.length;i++){
if(divs[i].id.match(pass)){//if they are 'see' divs
if (document.getElementById) // DOM3 = IE5, NS6
divs[i].style.visibility="visible";// show/hide
else
if (document.layers) // Netscape 4
document.layers[divs[i]].display = 'visible';
else // IE 4
document.all.divs[i].visibility = 'visible';
} else {
if (document.getElementById)
divs[i].style.visibility="hidden";
else
if (document.layers) // Netscape 4
document.divs[i].visibility = 'hidden';
else // IE 4
document.all.divs[i].visibility = 'hidden';
}
}
}
//-->
</SCRIPT>
