I currently am running a promotional code to get a discount to be given in my oscommerce shopping cart. I have working code when the text is manually entered on the shopping_cart.php page. -
-
<?php
-
echo '<td class="main">' . tep_draw_separator('pixel_trans.gif', '20', '1') . tep_draw_input_field('promo_code', '', 'size="10"') . tep_draw_separator('pixel_trans.gif', '5', '1') . 'Promotion Code (optional). Update cart to see discount.</td>';
-
?>
-
this calls the discount module and applies the discount when you manually enter the text "CLUB". The code for the discount follows... -
-
if (!tep_session_is_registered('promo_code')) {
-
tep_session_register('promo_code');
-
$promo_code = '';
-
}
-
-
include_once(DIR_WS_FUNCTIONS.'easy_discount.php');
-
$easy_discount->reset();
-
if($promo_code == 'CLUB')
-
{
-
$easy_discount->add('CCD','Coffee Club Discount',$cart->show_total()*0.1);
-
}
-
I am attempting to accomplish the same call with a checkbox or radio button. I have made numerous feeble attempts to no avail (more than I like to admit). One of my attempts is here -
<input type=checkbox name="promo_code" value="CLUB" onClick="submit();">
-
This seems to be close, if I enter "CLUB" in the text box and click the check box it will apply the discount. You're welcome to test this yourself at
http://www.konacoffee.com/catalog/1lb-extra-fancy-medium-roast.html
click add to cart and you'll see the text box for the promotional code, enter "CLUB" caps no quotes and you'll see the discount applied.
Any help and feedback is greatly appreciated.
Aloha from Kona,
Robin

You don't show how you're retrieving the value of the textbox. Please do.

Hi Markus,
Thank you for your help. That may be the problem? Maybe I'm not retrieving the value. The form post for this page is
<form name="cart_quantity" action="http://www.konacoffee.com/catalog/shopping_cart_action-update_product.html" method="post">
When I send the information by manually inputting the text you just click "Update" and the same page refreshes with the discount shown. It uses easy_discount.php.
Shown below -
-
<?php
-
class easy_discount {
-
var $discounts;
-
-
function easy_discount () {
-
$this->discounts = array();
-
}
-
-
function reset() {
-
$this->discounts = array();
-
}
-
-
function set($type,$description, $amount) {
-
$this->discounts[$type] = array('description' => $description, 'amount' => $amount);
-
}
-
-
function add($type,$description, $amount) { // obsolete
-
$this->discounts[$type] = array('description' => $description, 'amount' => $amount);
-
}
-
-
function clear($type) {
-
if (isset($this->discounts[$type])) unset($this->discounts[$type]);
-
}
-
-
function remove_type($type) { // obsolete
-
if (isset($this->discounts[$type])) unset($this->discounts[$type]);
-
}
-
-
function count() {
-
return sizeof($this->discounts);
-
}
-
-
function get($type) {
-
return $this->discounts[$type];
-
}
-
-
function total() {
-
reset($this->discounts);
-
$total = 0;
-
while (list($type, ) = each($this->discounts)) {
-
$total = $total + $this->discounts[$type]['amount'];
-
}
-
return $total;
-
}
-
-
function get_all() {
-
$discounts_array = array();
-
reset($this->discounts);
-
while (list($type, ) = each($this->discounts)) {
-
$discounts_array[] = array('description' => $this->discounts[$type]['description'],
-
'amount' => $this->discounts[$type]['amount']);
-
}
-
return $discounts_array;
-
}
-
}
-
?>

Hi Markus,
Is this what you mean by "retrieving the value of the textbox"
<form name="cart_quantity" action="http://www.konacoffee.com/catalog/shopping_cart.php?action=update_product" method="post">
Currently after you enter text in the text box and click an "update" button. The discount is applied...ie: the current code for manually entering and retrieving the text is here: -
<?php
-
echo '<td class="main">' . tep_draw_separator('pixel_trans.gif', '20', '1') . tep_draw_input_field('promo_code', '', 'size="10"') . tep_draw_separator('pixel_trans.gif', '5', '1') . 'Promotion Code (optional). Update cart to see discount.</td>';
-
?>
-
In the textbox that is made with this code the user can enter "CLUB", click "Update" and the discount is applied. I'm trying to do the same thing without them needing to manually type the text, They click the checkbox, the promo code text -"CLUB" is hidden. When they check the box the "onclick" updates the cart showing the discount.
Or any other way which would work better?
I hope that makes more sense.
I'm thinking I need to add the text to the onClick="submit(); command but I can't seem to properly do that.
Thank you - any and all who read this and have feedback.

No, you show how you pass the form.
You're passing the form using the method POST. Therefore, you should be retrieving it by $_POST['key_name'], but you haven't shown that part of your code yet.

Thank You. Yes this where I'm running into the brick wall. Would you be so kind as to show me how to retrieve it? I have tried numerous $_POST variations and
if (isset($_POST[''])) variations and either get syntax errors or I'm not retrieving the information. All I want to do is make it so my customer doesn't have to manually enter the text "CLUB", they can check the box and by doing so, the text they would of had to manually enter is sent as if they had entered it and the form is processed and the discount would apply.

If the name of the checkbox is promo_code, then check that it is in the POST array. -
if( isset( $_POST['promo_code'] ) )
-
// promo_code was selected
-
else
-
// promo_code wasn't selected
-

Thank you Markus....I think I'm getting close but still missing something. (feeling pretty stupid actually) Here is what I have that doesn't work. -
-
Coffee Club:<input type="checkbox" name="promo_code" value="CLUB" />
-
-
<?php
-
$promo_code = CLUB;
-
if( isset( $_POST['promo_code'] ) )
-
{
-
$easy_discount->add('CCD','Coffee Club Discount',$cart->show_total()*0.1);
-
}
-
?>
-
and here is what I have that does work...If you enter the text "CLUB" manually. -
-
<?php
-
echo '<td class="main">' . tep_draw_separator('pixel_trans.gif', '20', '1') . tep_draw_input_field('promo_code', '', 'size="10"') . tep_draw_separator('pixel_trans.gif', '5', '1') . 'Promotion Code (optional). Update cart to see discount.</td>';
-
-
-
if($promo_code == 'CLUB')
-
{
-
$easy_discount->add('CCD','Coffee Club Discount',$cart->show_total()*0.1);
-

Do you drink coffee? I have some really good coffee....guess I'm much better at coffee than coding. ;-)
Thank YOU,

Nope, that should work fine. Although, CLUB should be in quotes on line 5. What doesn't happen?
Can you show me the source of the html form please? Maybe the problem is with that.

Ok...I put the quotes. I expect that when I check the box and click update that the discount will be applied, but it isn't.

Here is the source code from shopping_cart.php with an item added. There is a lot going on here. Markus 6,050

I was about to give up when I noticed you've named both the checkbox and text input 'promo_code'
Name them differently and you'll be cruisin'.
Thank You Markus. It works!!! You da Man!!!
I think I had earlier except I left both in so one would cancel the other out. I almost gave up too. I really appreciate your help.
Aloha from Kona,

On to the next hurdle....
