Hi,

So what are you using to print the variable in the template?

e.g.
{$variable}

Or {php}echo $variable{/php}

Or what?

And do you use any modifier for the variable, or do you just use the
variable as assigned to?

I do all my calculations in PHP and let Smarty handle the display - I
thought that's what templates were all about.

The problem I have is that my display via $smarty-assign() was giving me an
incorrect display.

I then, as usual with such an error, thought there was something wrong with
the PHP code, so started echoing the output at the various steps. I still
thought the problem was in PHP, but when I decided to put the process into a
php file that did not include and $smarty interaction, the display was fine,
which is why I'm asking the question on this list.

If no-one has a solution, I'll need to think of a different way to display
the price to my users.

Cheers

George

Hi George,

maybe you did not assign $fee properly/at all...

There should be a line of code in your php-script like:

$smarty->assign('fee',$fee);

Within your template you then state {$fee} or as messju recommended
{"%.2f"|sprintf:$fee}
The latter modifies a string to get the proper number of floating values
(or however these are called)....

Hope that s...

$fee = [web-service response (in dollars and cents)]
settype($fee, "float");
$fee_type = gettype($fee);
$range = explode(",",strim($pr));
$rangecounter = count($range);
$rangecounter = ($rangecounter>1?$rangecounter-1:0);
$ccc_supp = floatval($rangecounter * 3);
settype($ccc_supp, "float");
$fee2 = $fee + $ccc_supp;

$smarty->assign('ccc_fee','The CCC QuickPrice for this request is:
$'.sprintf("%01.2f",$fee2)."<br>$ccc_terms");

All is handled in PHP before assignation. I'm only asking $smarty to display
my variable.

I've been using Smarty for 3 years now - across over 20 websites and this is
the first real hassle I've encountered.

Anyway, I'm off for the weekend now.

Hi George,

My test script using your example does not show anything wrong:

My PHP:

My Template "test.tpl"

The result when I use this code through the browser:
> The CCC QuickPrice for this request is: $1.22
> The CCC QuickPrice for this request is: $1.22

Also for smarty you will always need a template. Thus your code should
contain a $smarty->display(filename) which tell you which template you are
using. Smarty is not a pretty printing tool, but a template engine. So we
need variables (Assigned by $smarty->assign) and a template (Gives by
$smarty->display) to create a result.

Cheers,
Guido

smarty displays what you assign. nothing more nothing less.
again: the fact that you use smarty does not make this a smarty
issue.

maybe you have some locale settings that disturb your
float-conversions?

like this braindead behaviour of php:

setlocale(LC_ALL, "de_DE.UTF-8");
$foo = 10001/100;
echo $foo, "\n";
echo floatval("$foo"), "\n";

gives on my system:
100,01
100

Exactly. Assign the value to the template object as a string, not as a
float, and see what you get. Shouldn't matter, but at least then you'll
get the value in a more-or-less literal form. There generally oughtn't
be any need to using sprintf() in the template code. Also, do you have
error_reporting set to at least E_ALL?

None of the above displays anything; you assign a value to the Smarty,
but don't show the call to $smarty->display() or (and this is what both
I and others have asked for) what you put in the template. For the sake
of argument I'll assume your template just says
{$ccc_fee}

I think it's clear that the value being assigned is wrong, so this isn't
a Smarty issue, but a PHP one. This list gets more than its fair share
of off-topic PHP queries hence some reluctance to assist in non-Smarty
problems. However, I'll make some suggestions then bow out of the topic
(I'll assist off-list if you're really stuck).

Why are you using lots of settype() calls? Is that the result of some
hacks to try and resolve this problem? It's very rare that settype
should really be needed anywhere.

What does the following code give you?

$fee = [web-service response (in dollars and cents)]
var_dump($fee);
$range = explode(",",strim($pr));
$rangecounter = count($range);
$rangecounter = ($rangecounter>1?$rangecounter-1:0);
$ccc_supp = $rangecounter * 3;
var_dump($range, $rangecounter, $ccc_supp);
$fee2 = $fee + $ccc_supp;
var_dump($fee2, sprintf("%01.2f",$fee2));

Note that I use var_dump as that tells you both the value and the type in one.

The implication, which there's been nothing to suggest to the contrary
here, is therefore that the variable is wrong before it gets to Smarty.
Unless, that is, you're doing something in Smarty other than just
displaying what its sent, such as formatting code. That's why seeing the
relevant part of the template would .

I'm 90% sure this is nothing to do with Smarty, but I'm quite open to
being proved wrong on that.

I just tried the following code, which I suggest you also try:
===========================================
<?php
$fee = '160.44';
$pr = '9-27';
$ccc_terms = '';
$rt = 'Granted';

settype($fee, "float");
$fee_type = gettype($fee);
$range = explode(",",trim($pr));
$rangecounter = count($range);
$rangecounter = ($rangecounter>1?$rangecounter-1:0);
$ccc_supp = floatval($rangecounter * 3);
settype($ccc_supp, "float");
$fee2 = $fee + $ccc_supp;

$ccc_fee = $rt!='Granted'?'Not available through CCC: '
.($rt!=''?$rt:'no reason given'):'The CCC QuickPrice
for this request is: $'
.sprintf("%01.2f",$fee2)."<br>$ccc_terms";

var_dump($fee, $range, $rangecounter, $ccc_supp, $fee2, $ccc_fee);
?>
===========================================

It is as close I could get to your exact code, notice I substitute
"trim" for "strim", and calculated and 'var_dump'ed $ccc_fee rather than
using Smarty. The results I get are:

===========================================
float(160.44)
array(1) {
[0]=>
string(4) "9-27"
}
int(0)
float(0)
float(160.44)
string(51) "The CCC QuickPrice for this request is: $160.44<br>"
===========================================

All of those look fine to me. If you get the same results, and yet
$smarty->assign('ccc_fee',$ccc_fee);
... in your code and
{$ccc_fee}
... in your template shows something different, then I would be very
surprised.

However, suppose $fee is actually '160. 44' (note the space after the
..), or as Messju suggested '160,44' (comma instead of .) then the
conversion to float will give 160 not 160.44 and the results you are
getting. So corruption of the value of $fee would be where I'd go looking.

You should also be careful that a price of '1,234.44' doesn't get
converted to $1 by your method, for the same reasons.
