Using the "||" and "&&" operators

[jetlife76]

Ok here's my issue, im trying to create a program that will calculate the total cost of an item, tax, shipping and shipping date, so far i've ran into a problem setting up my "If" statement with the perameters needed to calculate the shipping cost, Here's the code i have  so far:

 

<?php

$Cost = $_POST['fielda'];

$Tax = ($Cost * .06);

$Sub = ($Cost + $Tax);

$Ship =

$Total = ($Cost + $Tax + $Ship);

 

if ( $Sub <= 25.99 ){

print "$Ship: 3.00<br>"; }

elseif ($Sub >= 26.00 || <= 50.99 ){

print "$Ship: 4.00<br>";}

elseif ($Sub >= 51.00 || <= 75.00) {

print "$Ship: 5.00<br>";}

elseif ($Sub > 75.00) {

print "Ship: 6.00<br>";}

else {

print ("Cost : $Cost<br> Tax: $Tax<br> Shippingtotal is $$Total");}

?>

 

Here's the error i keep getting:

 

Parse error: syntax error, unexpected T_IS_SMALLER_OR_EQUAL in C:\wamp\ on line 16

any help i can get will be greatly appreciated, I also need to know how to do the shipping date (15 days) as well if you can help with that as well

You need to repeat your variable for each test, e.g.:

 

elseif ($Sub >= 26.00 || $Sub <= 50.99 ){

Ok yea that was helpful, total brain freeze, but now im lost on how to define my variable for $Ship and should i have a seperate print statement to show the cost- tax-shipping & total amount?

try this:

 

<?php
$Cost = $_POST['fielda'];
$Tax = ($Cost * .06);
$Sub = ($Cost + $Tax);
$Ship = 0;

if ( $Sub <= 25.99 ){
   $Ship= 3.00; }
elseif ($Sub >= 26.00 || $Sub <= 50.99 ){
   $Ship= 4.00; }
elseif ($Sub >= 51.00 || $Sub <= 75.00) {
   $Ship: 5.00; }
elseif ($Sub > 75.00) {
   $Ship= 6.00; }

$Total = ($Cost + $Tax + $Ship);
print ("Cost : $Cost<br> Tax: $Tax<br> Ship: $Ship<br> Shipping total is $Total");}
?>

ok cool that seems to work, but when i put in a value larger than 50 it only gives me a 4.00 shipping when it should be 5 or 6

[darkspire]

its a logic error... take out the elseif's and use && instead of ||. that should fix it.

<?php
$Cost = $_POST['fielda'];
$Tax = ($Cost * .06);
$Sub = ($Cost + $Tax);
if ( $Sub <= 25.99 ) $Ship= 3.00; 
if ($Sub >= 26.00 && $Sub <= 50.99 ) $Ship= 4.00;
if ($Sub >= 51.00 && $Sub <= 75.00) $Ship: 5.00; 
if ($Sub > 75.00) $Ship= 6.00; 

$Total = ($Cost + $Tax + $Ship);
print ("Cost : $Cost<br> Tax: $Tax<br> Ship: $Ship<br> Shipping total is $Total");
?>

Or, you could build it in reverse.

<?php
$Cost = $_POST['fielda'];
$Tax = ($Cost * .06);
$Sub = ($Cost + $Tax);
if ( $Sub > 75.00 ) $Ship= 6.00; 
elseif ($Sub > 51.00 ) $Ship= 5.00;
elseif ($Sub > 26.00) $Ship: 4.00; 
else  $Ship= 3.00; 

$Total = ($Cost + $Tax + $Ship);
print ("Cost : $Cost<br> Tax: $Tax<br> Ship: $Ship<br> Shipping total is $Total");
?>

ok cool thanks, one more thing then i'll be good to go from here, im trying to also show the shipping date which is 15 days after the order date would i use the timestamp, "$ShipDate = mktime(0,0,0,date("m"),date("d")+1,date("Y"));"

but im only getting a list of numbers i want it to show the month spelled out, the day, year

How do i set the current date as well, last question and i swear im done

Thanks in advance

[darkspire]

$date1 = date(‘Y-m-d’);
$date2 = “2007-02-26″;
$days = (strtotime($date1) – strtotime($date2)) / (60 * 60
* 24);
echo ” No of $days difference”;

[jcbones]

I would use:

<?php

$currentDate = date('Y-m-d');

$shippingDate = date('Y-m-d',strtotime('+ 15 days'));
