[RESOLVED] Trouble with $pricing on HTML Form, having the correct price populate

[SeanWoods]

I have every part of my form working properly except for one.

I am having trouble getting my cost to populate on this page: http://www.grammarperfection.com/confirmorder.php

There are 3 different costs depending on how soon they want their document edited by:

* Standard - 3 Day/72 Hour Return - $5.00 Per Page
* Expedite - 2 Day/48 Hour Return - $7.50 Per Page
* Overnight - 1 Day/24 Hour Return - $9.00 Per Page

I am trying to have whatever selection is chosen from these options to have the price per page multiplied by the # of pages ($numCount).

I wrote the code where it will calculate the cost for the Standard $5 option (although it won't show 2 decimal places). This is the number of pages ($numCount) multiplied by 5, but how do I automatically have it chose the correct code based on which option they chose? - Standard $5, Expedite $7.50, Overnight $9

<?php

$number = $numCount;
echo "\$" . $number*5;
$formatted = number_format($number, 2);

?>

Code for this page:

<?php
$words = $_GET['words'];
?>

<?php @$format= $_POST['serviceOption'];
if( is_array($serviceOption)){
while (list ($key, $val) = each ($serviceOption)) {
echo "$val <br>";
}
}//else{echo "not array";}  

?></td>
                </tr>
                  <tr>
                    <td class="pagetext"><strong>Word Count/Pages</strong><br />
(300 Words=1 Page)</td>
                    <td class="pagetext">
<?php

$txtWordCount = $_POST['txtWordCount'];
$numCount = $_POST['numCount'];


echo " ". $txtWordCount . " Words / " . $numCount . " Pages";


?>

I don't understand why you wouldn't use some Javascript and show the cost in the first page, rather than making the user wait and possibly have to go back a page to make changes. The "pages" textbox is also redundant since 300 words = 1 page. The page count and cost could calculated on the front end using Javascript, which is better from a user standpoint.

I was going to post an example of the Javascript method, but I ran out of time. Maybe someone else can jump in.

You probably need to redesign your <select> statement to use integers as values -- or perhaps the price per page. This is a bit awkward to translate into price per page because your values are very lengthy text strings:

<option value="Standard - 3 Day/72 Hour Return - $5.00 Per Page">Standard - 3 Day/72 Hour Return - $5.00 Per Page</option>
<option value="Expedite - 2 Day/48 Hour Return - $7.50 Per Page">Expedite - 2 Day/48 Hour Return - $7.50 Per Page</option>
<option value="Overnight - 1 Day/24 Hour Return - $9.00 Per Page">Overnight - 1 Day/24 Hour Return - $9.00 Per Page</option>                     

If you did this instead:

<select name="serviceOption">
  <option value="standard">Standard - 3 Day/72 Hour Return - $5.00 Per Page</option>
  <option value="expedited">Expedite - 2 Day/48 Hour Return - $7.50 Per Page</option>
  <option value="overnight">Overnight - 1 Day/24 Hour Return - $9.00 Per Page</option>
</select>              

Then on the handling page, you could just do this:

switch ($_POST['serviceOption']) {
  case 'standard':
    $perPage = 5;
    break;
  case 'expedited':
    $perPage = 7.5;
    break;
  case 'overnight':
    $perPage = 9;
    break;
  default:
    echo 'ERROR: invalid service option';
}

And of course you are not echoing any numbers with decimal places. You assign the formatted number to a variable only after you've echoed the number and then you never echo the formatted version. try this:

$cost = $numCount*5;
echo number_format($cost, 2);

I must be doing something wrong, or I have something missing.

On the place on the form where I want the price to populate, how do I write it so it will only show the one price for the option selected?

If I put the below code, it does only show the one option price.

$cost = $numCount*5;
echo number_format($cost, 2); 

I thought, "ok, it works for showing only the cost at $5 per page, I must need to just copy and paste that for each other price." That only ends up showing all 3 prices at once. How to I write it to take only the selected option? Here is the code I have (which I have incorrect):

<?php
$cost = $numCount*5;
echo number_format($cost, 2);

$cost = $numCount*7.5;
echo number_format($cost, 2); 

$cost = $numCount*9;
echo number_format($cost, 2); 

?>

I took the above advice and tried shortening my <select> statements. But when I did so, it placed that shortened up wording ("standard", "expedited" and "overnight") and displayed that shortened up wording on the next page (confirmation) rather than showing the full description of the option. I ended up changing it back.

Also, on the suggestion above, it had me change <select name='serviceOption[]'> to <select name="serviceOption">. When I do so, the selected option will not populate on the next page.

I guess just take a look at my code and see what you think. Thanks for the help!

Code on previous page http://www.grammarperfection.com/checkout.php?serv=2&words=241which creates the drop down list with the selections:

<form action="confirmorder.php" method="post">
<select name='serviceOption[]'>
<option value="Standard - 3 Day/72 Hour Return - $5.00 Per Page"<?php echo $opt1?>>Standard - 3 Day/72 Hour Return - $5.00 Per Page</option>
<option value="Expedite - 2 Day/48 Hour Return - $7.50 Per Page"<?php echo $opt2?>>Expedite - 2 Day/48 Hour Return - $7.50 Per Page</option>
<option value="Overnight - 1 Day/24 Hour Return - $9.00 Per Page"<?php echo $opt3?>>Overnight - 1 Day/24 Hour Return - $9.00 Per Page</option>                     

       </select>     

Code on page where this selection is supposed to show the selection madehttp://www.grammarperfection.com/confirmorder.php (note: this page will look incomplete unless you navigate to it from previous page), as well as calculating the price by multiplying number of pages ($numCount) by the price per page for each selection:

//part above HTML
<?php
$words = $_GET['words'];

switch ($_POST['serviceOption']) {
  case 'Standard - 3 Day/72 Hour Return - $5.00 Per Page':
    $perPage = 5;
    break;
  case 'Expedite - 2 Day/48 Hour Return - $7.50 Per Page':
    $perPage = 7.5;
    break;
  case 'Overnight - 1 Day/24 Hour Return - $9.00 Per Page':
    $perPage = 9;
    break;
  default:
    echo 'ERROR: invalid service option';
} 
?>

//code where it should populate the price
<?php
$cost = $numCount*5;
echo number_format($cost, 2);

$cost = $numCount*7.5;
echo number_format($cost, 2); 

$cost = $numCount*9;
echo number_format($cost, 2); 

?>

that switch statement looks really awkward. it's not very common (or efficient) for a switch statement to be comparing big long strings like that. you'd probably better off keeping it the way I suggested and doing something like what I have below.

You also need to learn what it means to define a variable. that switch statement I have defines two variables. One is the $description of the service that has been selected and the other is the cost $perPage that one must pay for the service selected.

Once those vars are defined, you can echo them in other places.

<?php
$words = $_GET['words'];

switch ($_POST['serviceOption']) {
  case 'standard' : 
    $description = 'Standard - 3 Day/72 Hour Return - $5.00 Per Page';
    $perPage = 5;
    break;
  case 'expedited' :
    $description = 'Expedite - 2 Day/48 Hour Return - $7.50 Per Page';
    $perPage = 7.5;
    break;
  case 'overnight' : 
    $description = 'Overnight - 1 Day/24 Hour Return - $9.00 Per Page';
    $perPage = 9;
    break;
  default:
    echo 'ERROR: invalid service option';
} 
?>

//code where it should populate the price
<?php
$cost = $numCount*$perPage;
echo number_format($cost, 2);
?>

You're a genius! It works.

Now just one small problem and this page will be running 🙂

On the page with the drop down list, now that I have changed the code from:

<select name='serviceOption[]'>
<option value="Standard - 3 Day/72 Hour Return - $5.00 Per Page"<?php echo $opt1?>>Standard - 3 Day/72 Hour Return - $5.00 Per Page</option>
<option value="Expedite - 2 Day/48 Hour Return - $7.50 Per Page"<?php echo $opt2?>>Expedite - 2 Day/48 Hour Return - $7.50 Per Page</option>
<option value="Overnight - 1 Day/24 Hour Return - $9.00 Per Page"<?php echo $opt3?>>Overnight - 1 Day/24 Hour Return - $9.00 Per Page</option>                     

       </select>

to:

<select name='serviceOption'>
  <option value="standard">Standard - 3 Day/72 Hour Return - $5.00 Per Page</option>
  <option value="expedited">Expedite - 2 Day/48 Hour Return - $7.50 Per Page</option>
  <option value="overnight">Overnight - 1 Day/24 Hour Return - $9.00 Per Page</option>
</select>   

The drop down box which would normally send the option selected and post it on the last page (next to where I had trouble getting the price to show), but now it won't since I had to take out the [] in <select name='serviceOption[]'>. How can I get it to show the selection again and also show the entire line......what I mean is when I leave in the [], the price won't show, and it will only show "standard", "expedited" or "overnight" rather than the entire line, Standard - 3 Day/72 Hour Return - $5.00 Per Page, etc since switches don't like long lines? When I take out the [] the service option will not be displayed but the price will. I don't know how reliable it will be, but it seems to be working with the longer line (price), until I put the [] back in.

Here is the code I have which populates the selection made in the drop down box:

<?php @$format= $_POST['serviceOption'];
if( is_array($serviceOption)){
while (list ($key, $val) = each ($serviceOption)) {
echo "$val <br>";
}
}//else{echo "not array";}   

?>

No, it's onlY showing "standard", "expedited", or "overnight" because those are the possible values of the selection (the text that gets displayed to the user is irrelevant to the computer - this why why an option has both).

Having taken the [] out of the <select>, the field is no longer an array, so

if( is_array($serviceOption)){

will no longer be true. Instead $serviceOption would itself contain the value directly. (At least, it would if you had written "$serviceOption" instead of "$format" on the previous line).

The switch statement sneakyimp gave shows how you can take that value and get the corresponding display string.
