Código :
<?php
include 'conexion.php';
$con=conexion();
$res=mysql_query("select * from transporte",$con);
?>
<html>
<body>
<script type="text/javascript">
function validar(form) {
if (form.txt1.value <=4){
form.txt2.disabled=(form.txt1.value=='');
form.casilla[0].disabled=(form.txt1.value=='');
}
else {
form.casilla[1].disabled=(form.txt1.value=='');
}
}
</script>
<form method="post" action="eliminar.php">
<form>
<input type="text" name="txt1" onKeyUp="validar(this.form)" />
<input type="text" name="txt2" disabled />
<table border="1">
<tr>
<th></th>
<th>Nombre</th>
</tr>
<?php
while($fila=mysql_fetch_array($res)){
?>
<tr>
<th><input type="radio" name="casilla[]" value="<?php echo $fila["id_transporte"]; ?>" disabled></th>
<th><?php echo $fila["descripcion"]; ?></th>
</tr>
<?php
}
?>
</table>
</form>
</body>
</html>
este código si me funciona pero la diferencia es que los radios button no son cargados de una base de datos.
Código PHP :
html>
<head>
<script type="text/javascript">
function validar(form) {
if (form.txt1.value <=4){
form.r2.disabled=(form.txt1.value=='');
form.txt2.disabled=(form.txt1.value=='');
}
else {
form.r1.disabled=(form.txt1.value=='');
}
}
</script>
</head>
<body>
<form>
<input type="text" name="txt1" onKeyUp="validar(this.form)" />
<input name="r2" type="radio" value="" disabled>
<input name="r1" type="radio" value="" disabled>
<input type="text" name="txt2" disabled />
</form>
</body>
</html>
