Value isn't processing properly in If Statements??

[suess0r]

OK - I know this is probably sloppy coding.. but here's the gist of what i'm trying to do. I want to print $total according to which 2 values were chosen from $size and $quantity. But the $total always stays the value of each If validation section.. So if the $size = postcard4-6 then the $total is always 324.95 instead of 39.95

 

<?php

            $size = $_POST['postcard-size'];

            $quantity = $_POST['postcard-quantity'];

            $error = 1;

           

            echo $size;

            echo $quantity;

           

            if ($size == "")

              $total = 0.00;

            if (!isset($quantity))

              $total = 0.00;

          //Note: Need validation for if isset($size) && !isset($quantity)

             

            if (isset($size, $quantity)) {

              //Validation for Postcard 4x6

               

                  if ($size == "postcard4-6" && $quantity = 100) {

                  $total = 39.95;

              }

              if ($size == "postcard4-6" && $quantity = 250){

                  $total = 79.95;

              }

              if ($size == "postcard4-6" && $quantity = 500){

                  $total = 89.95;

              }

              if ($size == "postcard4-6" && $quantity = 1000){

                  $total = 114.95;

              }

              if ($size == "postcard4-6" && $quantity = 2500){

                  $total = 229.95;

              }

              if ($size == "postcard4-6" && $quantity = 5000){

                  $total = 324.95;

              }

             

                //Validation for Postcard 8.5x5.5

              if ($size == "postcard85-55" && $quantity = 100) {

                  $total = 69.95;

              }

              if ($size == "postcard85-55" && $quantity = 250){

                  $total = 119.95;

              }

              if ($size == "postcard85-55" && $quantity = 500){

                  $total = 149.95;

              }

              if ($size == "postcard85-55" && $quantity = 1000){

                  $total = 229.95;

              }

              if ($size == "postcard85-55" && $quantity = 2500){

                  $total = 399.95;

              }

              if ($size == "postcard85-55" && $quantity = 5000){

                  $total = 589.95;

              }

             

                //Validation for Postcard 8.5x5.5

              if ($size == "postcard6-11" && $quantity = 100) {

                  $total = 0.00;

                  //$error = 2;

                 

              }

              if ($size == "postcard6-11" && $quantity = 250){

                  $total = 0.00;

                  //$error = 2;

              }

              if ($size == "postcard6-11" && $quantity = 500){

                  $total = 0.00;

                  //$error = 2;

              }

              if ($size == "postcard6-11" && $quantity = 1000){

                  $total = 349.95;

              }

              if ($size == "postcard6-11" && $quantity = 2500){

                  $total = 499.95;

              }

              if ($size == "postcard6-11" && $quantity = 5000){

                  $total = 799.95;

              }

            }

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

              echo '$'.$total;

            //if ($error = 2)

              //echo "$0.00

Sorry, you need to select 1,000+ to get postcards in 6x11";

                  // echo '  <input type="hidden" name="amount" value="'.$total.'">';

              ?>

 

I've tried swapping the '=' with '==' in the if statement..

ex: if ($size == "postcard6-11" && $quantity == 1000){

                  $total = 349.95;

 

that didn't help. I echo'd my $size and $quantity and i'm getting all the right values - like in the above example i get $size = postcard6-11 and $quantity = 1000.. i'm sure i'm just doing something stupid (my PHP is a bit rusty)..

Change all the extra if's that set the $total to else if's:

                if ($size == "postcard4-6" && $quantity = 100) {
                  $total = 39.95;
               }
               else if ($size == "postcard4-6" && $quantity = 250){
                  $total = 79.95;
               }
              else if ($size == "postcard4-6" && $quantity = 500){
                  $total = 89.95;
               }
               else if ($size == "postcard4-6" && $quantity = 1000){
                  $total = 114.95;
               }
               etc...

 

That will make only one possibility for $total.
