[knoahg]

Hi people im still a begginer in PHP this is the code i have so far and it only accepts entering values and adding with the button. So how can i generate two random numbers on the two boxes and calculate the result.
Thank You.

<form name="form1" method="post" action="">
   value1:
     <label>
  <input type="text" name="value1">
  </label>
  <p>&nbsp;</p>
  <p>
    <label>
    value2: 
    <input type="text" name="value2">
    </label>
  </p>

 
  <p>
    <label>
    <input type="submit" name="submit" value="calculate">
    </label>
   </form>
<?php
$_POST[calculate] =="add"; {
$result = $_POST[value1] + $_POST[value2];
}
echo $result;
?>

You can do it like this:

Code: [Select]

<form name="form1" method="post" action="">
   value1:
     <label>
  <input type="text" name="value1" value="<?php echo rand(0, 1000000); ?>">
  </label>
  <p>&nbsp;</p>
  <p>
    <label>
    value2: 
    <input type="text" name="value2" value="<?php echo rand(0, 1000000); ?>">
    </label>
  </p>

 
  <p>
    <label>
    <input type="submit" name="submit" value="calculate">
    </label>
   </form>
<?php
if($_POST[calculate] == "add"){
$result = $_POST['value1'] + $_POST['value2'];
}
echo $result;
?>
