Hello guys,
I am sorry to disturb you.
I followed a tutorial and i am a newbe to php but want to learn.
My calculator doesn't work, i dont see what is wrong.
Please can someone explain what the issue is or give me a hint.
Thank you in advance.
Html Code:
<form method="post" action="calc.php">
<input type="text" name="nummer1" placeholder="nummer1" />
<label for="kies">kies</label>
<select name="reken" id="kies">
<option>selecteer</option>
<option value ="plus">+</option>
<option value ="min">-</option>
<option value ="delen">÷</option>
<option value ="maal">x</option>
</select>
<input type="number" name="nummer2" placeholder="nummer2" />
<input type="submit" value="calculeer" />
</form>
php code:
function bereken ()
{
$nummer1 = $_POST['nummer1'];
$nummer2 = $_POST['nummer2'];
switch ($_POST['reken'])
{
case "plus":
$plus = $nummer1 + $nummer2;
return $plus;
break;
case "min":
$min = $nummer1 - $nummer2;
return $min;
break;
case "delen":
$deel = $nummer1 / $nummer2;
return $deel;
break;
case "maal":
$maal = $nummer1 * $nummer2;
return $maal;
break;
default:
echo "bereken op een andere maniet";
}
}
echo "het resultaat is :". bereken();
?>
