[RESOLVED] unknown variable

[Supplement]

On the how many input box in red, I'm going to allow a user to enter any specific number... based on that number it needs to calculate whatever the $seconds variable is equal too at the time. Than the output should echo the seconds, minutes, hours fields. I hope that makes sense... Any help would be greatly appreciated. Thanks in advance.

$results = sql::clean_row("
    select
    sum(quantity) as quantity,
    (sum(duration_minutes) * 60) + sum(duration_seconds) as duration_seconds
from event.dbo.process_data
where process_id=$process_id");

//echo $results['duration_minutes'] . " " . $results['duration_seconds'] . " " . $results['quantity'] . "<br />";

$seconds = floor($results['duration_seconds'] / $results['quantity']);
$minutes = $seconds/60;

 
echo "<br />Quantity  " . $results['quantity']. "&nbsp;&nbsp;&nbsp; |&nbsp;&nbsp;&nbsp;  time in seconds ($seconds) / 60 = total time in minutes ($minutes)";

<table>
<form action="<?php echo matry::here(array('page'=> 'cal')); ?>" method="POST">    
<tr><td><?php inp('how_many'); ?></td><td> * <?php echo $seconds; ?></td></tr>
<tr><td>This many Seconds:</td></tr> 
<tr><td>This many Minutes:</td></tr>
<tr><td>This many Hours:</td></tr>
<tr><td>This many FTE:</td></tr>
<tr><td><input type="submit" value="Calculate" name="submit" /></td></tr>
</form>

I guess it would probably help if I actually added a form action and a submit button.

Help please.

This is what i got so far... but how do i assign the 'how_man' input box to multiply against the $seconds variable based on whatever is input in the 'how_many' input box? I hope this makes sense.. i need help. thanks in advance.

<table>
<form name="calc" action="<?php echo matry::here(array('page'=> 'calc')); ?>" method="POST"> 
<tr><td><?php inp('how_many'); ?></td><td> * <?php echo $seconds; ?></td></tr>
<tr><td>This many Seconds:</td></tr> <?php echo $result; ?>
<tr><td>This many Minutes:</td></tr>
<tr><td>This many Hours:</td></tr>
<tr><td>This many FTE:</td></tr>
<tr><td><input type="submit" value="Calc" name="submit" /></td></tr>
</form> 
</table>


<?php 

$page = $_GET['calc']; 

// Defining the "calc" class 
class calc { 
     var $how_many; 
     var $seconds; 

  

          function multiply($how_many,$seconds) 
          { 
                   $result =$how_many * $seconds; 
                    echo("The product of $how_many and $seconds is $result<br><br>"); 
                    echo("$how_many x $seconds = $result"); 
                    exit; 
           } 
} 
$calc = new calc(); 


foreach($how_many['how_many'] as $result) {
    echo $result['seconds'], '<br>';
}

?> 

 


<?php 
if($page == "calc"){ 
$how_many = $_POST['how_many']; 
$seconds = $_POST['seconds']; 

    if($oper == "multiply"){ 
          $calc->multiply($how_many,$seconds); 
     } 
} 
?>
