Hi, I'm trying to force 2 decimal places with the following function but it 's not working.  Any suggestions? 

Code: [Select]
function ShippingCost() {
$shippingCost = 4.00;
    number_format($shippingCost,2);
return $shippingCost;
}

Hey, just wondering what would be the best way of adding .1 to a string.

For example:

Code: [Select]
$newversion = $currentversion + '0.0.1';
$newversion is taken from a db, lets say for this example it is 0.2.1

This code simply outputs 0.2

Any ideas?

Thanks =)

i am echoing out a value which is 1.2900

but i want it to echo out 1.29
how do i do this?

Hi..

I encountered problem in rounding of numbers into two decimal places.

here is my sample code:


if($W4_STATUS == 1 AND $DEPENDENTS == 0 AND $TotEarn >= 7917 AND $TotEarn <= 12500) {
   $TAX = ($TotEarn - 7917);
   $TAX = (937.50 + ($TAX * .25));
   $TAX = number_format($TAX, 2, '.', '');
}


for example from this:

 $TAX = ($TotEarn - 7917);
  $TAX = (937.50 + ($TAX * .25));

the output is: 1417.615

using this:

$TAX = number_format($TAX, 2, '.', '');

the output was : 1417.61

but it should be : 1417.62

Thank you

Bascially i add a couple numbers up and display the sum.

sometimes the number is something like this: 234.237

i want it to display : 234.24

i realize its needs "round()" in it but i dont know how to use it..

any help?

Hi

I am using Zen-Cart to which I have made significant changes.  Two years ago I managed to change the Products Sort Order from Integer to Decimal(5,2) to store books such as 1, 1.5, 1.75, 2 etc.  Regrettably we had a major server issue and I also lost the new coding.  Having restored everything else whenever we enter a book series number such as 1.5 it only stores as 1.

To date the zen-Cart forums have been unable to offer a solution so I am reaching out to see if anyone else can advise me of how to get this working again please.

 

Thanks in advance

Owen

I know this should be easy.... However, to validate a 7-digit phone number, I wrote this:

Code: [Select]
<?php
if(!empty($_POST['mobile_number'])) {
          if(!is_numeric($_POST['mobile_number']) || strlen($_POST['mobile_number']) != 7) {
            $errors[] = 'Please enter a 7-digit number without spaces or dashes for your <strong>Mobile</strong>.';
          } else {
            $_SESSION['mobile_number'] = $_POST['mobile_number'];
          }
      } else {
        $_SESSION['mobile_number'] = '';
      }
... but now I realise that numeric/integer validation won't work because where I am - in Ireland - mobile numbers can start with an initial zero, too. So, the following mobile numbers are possible:
0123456 0224466
How can I ensure that:
each digit in the mobile number is numeric an initial zero is possible there are exactly 7 digits
I suppose I loop through each digit, ensuring that that digit is numeric and break out of the loop if a non-numeric digit is encountered..?
Any suggestions?

TIA
