Value stays the same no matter which choice made in dropdown!?!

[suess0r]

Hi,

 

I'm trying to make the selected dropdown match the original choice after the page submits to itself... While doing so I some how managed to make $quantity always = 5000. Can I get a second pair of eyes on this or am i just going crazy? ;x

 

This first part works fine... and an example of what i'm trying to do with the second portion

<select name="postcard-size" size="1">

                <option value="" >-Please Select-</option>

                <option value="postcard4-6"

<?php $size = $_POST['postcard-size'];

if ($size == "postcard4-6") echo "selected: selected"; ?>

>Postcards 4" x 6"</option>

                <option value="postcard85-55"

<?php $size = $_POST['postcard-size'];

if ($size == "postcard85-55") echo "selected: selected"; ?>

>Postcards 8.5" x 5.5"</option>

                <option value="postcard6-11"

<?php $size = $_POST['postcard-size'];

if ($size == "postcard6-11") echo "selected: selected"; ?>

>Postcards 6" x 11"</option>

              </select>

 

This is the part that's giving me trouble - I echo'd $quantity and it's always 5000 no matter what choice they make.

 

   

        <select name="postcard-quantity" size="1">

                <option value="">-Please Select-</option>

                <option value="100"

<?php $quantity = $_POST['postcard-quantity'];

if ($quantity = 100) echo "selected: selected"; ?>

>100</option>

                <option value="250"

<?php $quantity = $_POST['postcard-quantity'];

if ($quantity = 250) echo "selected: selected"; ?>

>250</option>

                <option value="500"

<?php $quantity = $_POST['postcard-quantity'];

if ($quantity = 500) echo "selected: selected"; ?>

>500</option>

<option value="1000"

<?php $quantity = $_POST['postcard-quantity'];

if ($quantity = 1000) echo "selected: selected"; ?>

>1,000</option>

<option value="2500"

<?php $quantity = $_POST['postcard-quantity'];

if ($quantity = 2500) echo "selected: selected"; ?>

>2,500</option>

<option value="5000"

<?php $quantity = $_POST['postcard-quantity'];

if ($quantity = 5000) echo "selected: selected"; ?>

>5,000</option>

              </select>

I thought it might have something to do with the 2nd set of values being all numbers like <option value=5000 instead of "5000" and that didn't help - I also changed it to echo 'selected: "selected"'; but that didn't help either. Appreciate all the help.

In the first part uve used:

 

if($this == 'that'){
    do smth;
}

 

In the second part u have:

 

if($this = 'that'){
    do smth;
}

 

Its your equality operators. Not '=' but '=='.

That portion works but the calculation isn't working anymore...

 

are you sure that the if statement doesn't call for one "=" if it's dealing with numerics??

 

if ($x = 100)

 

vs if ($x == "one hundred")

OK - I know this is probably sloppy coding.. but here's the gist of what i'm trying to do. The $total is staying at the bottom value of each If validation section.. So if the $size = postcard4-6 then the $total is always 324.95

 

<?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 <br> 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)..
