I am trying to create a form where if you fill in a number like 11 you get a response with a color type. I know that I have to change $tulp, but I don't know what to do.
<form name= "gemiddelden" action= "" method="post">
<p>Geelzweem (%): <input type="text" name="getal1"/></p>
<p><input type="submit" name="Bepaal" value="Bepaal"/></p>
</form>
$tulp = date("H");
if($tulp == 10) {
echo("Lichtgeel");
}
else if($tulp >10 && $tulp <20)
{
echo("Geel");
}
else if($tulp >20 && $tulp <30)
{
echo("Zon geel");
}
else if($tulp >30 && $tulp <40)
{
echo("Diep Geel");
}
else if($tulp >40 && $tulp <50)
{
echo("Zwavel Geel");
}
else if($tulp >50 && $tulp <60)
{
echo("Intens Geel");
}
else if($tulp >60 && $tulp <70)
{
echo("Verzadigd Geel");
}
else if($tulp >70)
{
echo("Dit mag niet");
}
else {
echo("Error");
