cannot sum specific variables

[silversubey]

Hello all.
I have a form that users are able to enter dollar amounts for each month and add them to the table. i am having difficulty adding cells that display the totals. For example, rows have 12 columns(one for each month) I would like to have a 13th that totals the entire row. Also at the bottom of the table, i need to have a total for only that column. I hope this makes sense. Below is the code for one of the tables.

// income
    $_SESSION["a$CDID"]['pl']['income']['0'] = '';
    if (isset($_POST['iicomp']))
    {
        $mkey = $_POST['iicomp'];
        $istate = $_POST['completed'];
 
    }
    if (isset($_GET['idel']))
        {
        unset($_SESSION["a$CDID"]['pl']['income'][$_GET['idel']]);
        foreach ($_SESSION["a$CDID"]['pl']['income'] as $line)
            $tmp[] = $line;
        $_SESSION["a$CDID"]['pl']['income'] = $tmp;
        }
    if (isset($_POST['income']))
    {
        if (!empty($_POST['key']))
            $_SESSION["a$CDID"]['pl']['income'][$_POST['key']] = $_POST['income'];
        else
            $_SESSION["a$CDID"]['pl']['income'][] = $_POST['income'];
    }
    if (count($_SESSION["a$CDID"]['pl']['income']) > '1')
    {
        foreach ($_SESSION["a$CDID"]['pl']['income'] as $key => $val)
        {
                if ($key != '0')
                    $PRINT_INCOME .= '
                    <tr class="input" '.$istyle.'><td>'.$key.'. '.$val['descript'].'</td><td>'.$val['jan'].'</td><td>'.$val['feb'].'</td>
                    <td>'.$val['mar'].'</td><td>'.$val['apr'].'</td><td>'.$val['may'].'</td><td>'.$val['jun'].'</td><td>'.$val['jul'].'</td><td>'.$val['aug'].'</td><td>'.$val['sep'].'</td><td>'.$val['oct'].'</td><td>'.$val['nov'].'</td><td>'.$val['dec'].'</td>
<td>"this is where I have been trying to insert a Sum for the row"</td>                    
<td align="center"><a href="pl.php?cdid='.$CDID.'&iedit='.$key.'"><input type="image" src="icon-blue-check.gif"</a></td><td><a href="pl.php?cdid='.$CDID.'&idel='.$key.'"><input type="image" src="icon-red-minus.gif"</a></td></tr>';
        }
    }
    else
        $PRINT_INCOME = '<tr class="row"><td></td></tr>';
    if (isset($_GET['iedit']))
 

The code for displaying the row is

<?PHP if (isset($PRINT_INCOME)) echo $PRINT_INCOME; ?>
 

Thankyou

Hi Subey,

I didn't quite understand the need for certain variables, but I've simplified your script:


[PHP]
<form id="form1" name="form1" method="post" action="">
<table width="100%" border="1" cellspacing="0" cellpadding="0">
<tr>
<?php

$CDID = 1;
$account = "a{$CDID}";


$_SESSION[$account]['pl'] = @$_POST['income'];

$total = 0;


for($i=0; $i<12; $i++){

$value = NULL;

if (isset($_POST['income'][$i])) $value = $_POST['income'][$i];

print "<td><input type='text' name='income[]' value='$value' style='width:50px; border:none; background-color:yellow;' /></td>";

$total = $total + $value;
}

print "<td>$total</td>";

?>
</tr>
</table>

<input type="submit" name="button" id="button" value="Total up" />
[/PHP]

Ps the yellow boxes are form fields

Regards
