Getting wrong results on php function

[wesley_santos2002]

Hello everyone, im having problems with this function to add numbers from a form, in the form i have $max1 to $max12 and $mand1 to $mand12, so what the function does is simply make the sum of 12 vars, "max" and "mand", so i use the same function for both results, it works perfectly for "mand" but for "max" it's not adding whatever comes after ".", like: 1.5 + 1.7 is resulting in only 3, when it should be 3.2, whats confusing me it's that it's working just fine with the values from $mand1 to $mand12, i hope that you guys can help me out, btw, i'm just starting at PHP and already love it, thank's to everyone in advance.

Your code has a bug.  If you post it, someone might be able to tell you more.

Here's the function:

function soma_T($valor1, $valor2, $valor3, $valor4, $valor5, $valor6, $valor7, $valor8, $valor9, $valor10, $valor11, $valor12) {

$total = $valor1 + $valor2 + $valor3 + $valor4 + $valor5 + $valor6 + $valor7 + $valor8 + $valor9 + $valor10 + $valor11 + $valor12;

 

return $total;

}

 

and here's the code in the CGI:

$max1 = $_POST['max1'];

$max2 = $_POST['max2'];

$max3 = $_POST['max3'];

$max4 = $_POST['max4'];

$max5 = $_POST['max5'];

$max6 = $_POST['max6'];

$max7 = $_POST['max7'];

$max8 = $_POST['max8'];

$max9 = $_POST['max9'];

$max10 = $_POST['max10'];

$max11 = $_POST['max11'];

$max12 = $_POST['max12'];

 

$mand1 = $_POST['mand1'];

$mand2 = $_POST['mand2'];

$mand3 = $_POST['mand3'];

$mand4 = $_POST['mand4'];

$mand5 = $_POST['mand5'];

$mand6 = $_POST['mand6'];

$mand7 = $_POST['mand7'];

$mand8 = $_POST['mand8'];

$mand9 = $_POST['mand9'];

$mand10 = $_POST['mand10'];

$mand11 = $_POST['mand11'];

$mand12 = $_POST['mand12'];

 

$superiores_total = soma_T($max1, $max2, $max3, $max4, $max5, $max6, $max7, $max8, $max9, $max10, $max11, $max12);

$inferiores_total = soma_T($mand1, $mand2, $mand3, $mand4, $mand5, $mand6, $mand7, $mand8, $mand9, $mand10, $mand11, $mand12);

 

<tr bgcolor="#9cc1e1">

<td>

<br />

<strong>DISCREPÂNCIA ENTRE OS ARCOS</strong><br />

<strong>12 Mand =</strong> <?php print $inferiores_total; ?><br />

<strong>12 Max =</strong> <?php print $superiores_total; ?>

</td>

 

I hope this will make it clear, you see, the same function works fine for 12 Mand, but not for 12 Max, it just ignores whatever comes after "."

[smoseley]

That code would not generate the result you posted.

 

Show us the form.

I don't see any errors in the code.  It should work just fine.

[smoseley]

The only suggestion for improvement that I can make is:

 

$superiores = array();
$inferiores = array();
for ($i = 1; $i <= 12; $i++) {
    $superiores[$i] = (double) urldecode($_POST["max{$i}"]);
    $inferiores[$i] = (double) urldecode($_POST["mand{$i}"]);
}

$superiores_total = array_sum($superiores);
$inferiores_total = array_sum($inferiores);

That's why i'm puzzled, even being a noob on this i don't see anything wrong with the code, 1.5 + 1.5 + 1.5 = 4.5, it gives me 3, seems like the problem happens not in the function... well, I'll try to make the way you sugested, thank you for your attention. =D

Your previous post said 1.5 + 1.7 = 3.  Different result than 1.5+1.5+1.5 = 3.

 

The latter post makes me believe it's a urldecoding issue.  Use my code and see how it works.

[wesley_santos2002]

Problem solved, your code worked just fine, than you for you help on this man

[smoseley]

FYI, I think the problem is that the "." was probably being urlencoded (to %3A) and not implicitly decoding on the server.  So when you performed addition, it was casting the number to an (int), thus truncating everything after % symbol.

 

I'm glad the fix worked.
