Having trouble with number_format

[jetlife76]

Trying to get my output to to show 2 decimal places but keep getting syntax errors please help.

Here's the code i have.

 

<?php
// Input Data From Form
$Cost = $_POST['fielda'];
//$Cost2 = number_format(,2);
//Set Current Date & Shipping Date (15 days)
$Date = date('l, F d, Y');
$ShipDate = date('F d, Y',strtotime('+ 15 days'));

$Tax = ($Cost * .06);
$Ship = 0;
//$Sub = ($Cost + $Tax);

//Calculate Shipping
if ($Cost <= 25.99 ){
   $Ship = 3.00; }
if ($Cost >= 26.00 && $Cost <= 50.99 ){
   $Ship = 4.00;}
if ($Cost >= 51.00 && $Cost <= 75.00) {
   $Ship = 5.00;}
if ($Cost > 75.00) {
   $Ship = 6.00;}
   
   //Calculate Order Total
$Total = ($Cost + $Tax + $Ship);

print " Date: $Date<br><br>";
print " Cost : $$Cost<br><br> Tax: $$Tax<br><br> Shipping: $$Ship<br><br> Total: $$Total<br><br>";
print "Estimated Ship Date is $ShipDate<br> " ;

?>

what are the syntax errors?

sorry,

The posted code isn't generating that error. Post the actual code that's causing the error, and please post it within

 . . . 

BBCode tags.

[jetlife76]

sorry the second code i posted is the one with the error

[jnvnsn]

print number_format (" Cost : $$Cost<br><br> Tax: $$Tax<br><br> Shipping: $$Ship<br><br> Total: $$Total<br><br>",2);

 

you passed invalid variables to the number_format function. remove those.

[Pikachu2000]

You can't feed an entire string to the number_format function like that. It would have no idea how to operate on it, as it expects a float/double value. You need to format each number individually, either prior to echoing the string, or or by concatenating the output into the string as it's echoed. Doing it prior would result in more readable code.

 

$number1 = 123.45678;
$number2 = 456.78901;

$number1 = number_format($number1, 2);
$number2 = number_format($number2, 2);

echo "Number1 is: $number1, and Number2 is: $number2";

 

I also see no reason for you to be using variable variables here.

Cost : $$Cost<br><br> Tax: $$Tax<br><br> Shipping: $$Ship<br><br> Total: $$Total<br><br>

[jetlife76]

ok i've done that but now it says lines 16 & 18 have undefined variables, Ship and Tax, i thought they were defined aleady

<?php
// Input Data From Form
$Cost = $_POST['fielda'];

//Set Current Date & Shipping Date (15 days)
$Date = date('l, F d, Y');
$ShipDate = date('F d, Y',strtotime('+ 15 days'));

$Cost2 = number_format($Cost,2);
$Tax2 = number_format($Tax,2);
$Tax = ($Cost * .06);
$Ship2 = number_format($Ship,2);
$Ship = 0;

//$Sub = ($Cost + $Tax);

//Calculate Shipping
if ($Cost <= 25.99 ){
$Ship = 3.00; }
if ($Cost >= 26.00 && $Cost <= 50.99 ){
$Ship = 4.00;}
if ($Cost >= 51.00 && $Cost <= 75.00) {
$Ship = 5.00;}
if ($Cost > 75.00) {
$Ship = 6.00;}

//Calculate Order Total
$Total = ($Cost + $Tax + $Ship);

$Total2 = number_format($Total,2);
print "Date: $Date<br><br>";
print "Cost: $$Cost2<br><br>";
print "Tax: $$Tax2<br><br>";
print "Shipping: $$Ship2<br><br> $$Total<br><br>";
print "Total: $$Total2<br><br>";
print "Estimated Ship Date is $ShipDate<br> " ;
?>

Works just fine for me, copied and pasted and made $cost a random number.

They need to be defined before you attempt to use or access their values . . .

thanks i found wut was wrong with it, one more question please? 

Trying to get the date function to handle a leap year, any help?

[Pikachu2000]

What do you mean?

[jetlife76]

Since i have my shipping date to automatically configure 15 days after the order date, i need it to adjust to a leap year, in case the order is made the last day in feb.(29) on a leap

[jetlife76]

nevermind i figured it out thanks for all your help guys

Since i have my shipping date to automatically configure 15 days after the order date, i need it to adjust to a leap year, in case the order is made the last day in feb.(29) on a leap

 

And, how are you determining 15 days? You shouldn't need any special handling for leap years if you did it right. It would just "work".

 

//Create timestamp 15 days in future
$ship_date_ts = str_to_time('+15 days');
//Format the ship date
$formatted_ship_date = date('m-d-Y', $ship_date_ts);

Ok if anyone can help, i need to put my shipping calculations in a programmer defined function, any help, i kno it's something simple just can't get my brain started this morning.

You seem to be making less sense the more you explain things.  Copy and paste?  Call a function?  make a web service?  We have no idea what you're talking about.

 

Did you read what was said about leap years?  PHP handles them for you.

[jetlife76]

Well i was told that i need to use a function to calculate the shipping cost, if that makes more sense.

Ok...you have a bunch of code.  put that code into a function.  The manual will be helpful here. 

[jetlife76]

ok here's what i got, still don't truly understand the "function" though.

 

<?php
// Input Data From Form
$Cost = $_POST['fielda'];
//Calculate tax 
$Tax = ($Cost * .06);

$Ship = 0;

//Set Current Date & Shipping Date (15 days)
$Date = date('l, F d, Y');
$ShipDate = date('F d, Y',strtotime('+ 15 days'));

//Calculate Shipping
function shipping_cost($Cost) {

if ($Cost > 0 && $Cost <= 25.00 ){
$Ship = 3.00; }
if ($Cost >= 25.01 && $Cost <= 50.00 ){
$Ship = 4.00;}
if ($Cost >= 50.01 && $Cost <= 75.00) {
$Ship = 5.00;}
if ($Cost > 75.00) {
$Ship = 6.00;}

return $Ship; }

//Calculate Order Total
$Total = ($Cost + $Tax + $Ship);


$Cost2 = number_format($Cost,2);
$Tax2 = number_format($Tax,2);
$Ship2 = number_format($Ship,2);
$Total2 = number_format($Total,2);


    print "Date: $Date<br><br>";
    print "Cost: $$Cost2<br><br>";
     print "Tax: $$Tax2<br><br>";
print "Ship: $$Ship2<br><br>";
   print "Total: $$Total2<br><br>";
print "Estimated Ship Date is $ShipDate<br> " ;
?>

As much as it pains me to say it: read the manual.  Functions are one of the most basic concepts of computer science.  You have to call a function in order for it to do anything and (in your case) store the return value somewhere.  Ask your professor if you need help with this, functions are very simple to understand.

[jetlife76]

Thanks for your help i forgot to call it, got it working, sorry for being such a NEWB, lol
