Hi and welcome

what is 'recompute' and do you have an example (maybe you can build a quick and dirty static form?)

in place to have a buttom to calculate price * quantity, by line of products (when i want to change quantity) , i want to have only one button which calculate all quantity*price for all shopping.

it's better when you have many quantities products change

do you unterstand more ?

this is not possible in most of the shopping carts if this is only to raie the amount on one page you should try some javascript code

ok

i finish without javascript and it runs

thanks

I would like to do the same.  The website I'm trying to work into is the db_cart is http://www.debmoe.com/slidesorderform.php .

Mine works the same as db_cart but all I want to do is have a unit price and total for each $row  of db_cart_btn_only.php.

Please help.

Deb

It would be great if you could post how you worked this out for other users. I would have just used javascript, but if PHP can/will do it - I'd like to try it next time I have the need (which could be any day).

I guess there is no other way than some Ajax function to calculate the (new) price without refreshing the page

I believe I'm close but can't figure it out.  I'm getting the title for each row and also for the total of the cart but I get this error:

Total value ROW:
Notice: Undefined variable: val in /home/debmoe3/public_html/classes/db_cart/db_cart_example.php on line 91

Notice: Undefined variable: val in /home/debmoe3/public_html/classes/db_cart/db_cart_example.php on line 91
$ 0,00

I have :

Code:

<?php while ($prod_obj = mysql_fetch_object($prod_result)) { ?>
  <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
    <label for="prod_<?php echo $prod_obj->id; ?>">
    <b><?php echo $prod_obj->name; ?></b><br>
    <?php echo $prod_obj->description." - price: ".$myCart->format_value($prod_obj->price); ?>

    </label>
    <input type="text" name="quantity" size="5" value="0">
<input type="hidden" name="price" value="<?php echo $prod_obj->price; ?>">
<input type="hidden" name="art_no" value="<?php echo $prod_obj->art_no; ?>">
<input type="hidden" name="product" value="<?php echo $prod_obj->name; ?>">
<input type="hidden" name="amount" value="<?php echo $prod_obj->amount; ?>">

<p>Total value ROW:  <b> <input type="hidden" name="amount" value="0"><?php echo $myCart->format_value($val['price'] * $val['quantity']); ?></b></p>
<input type="submit" name="add" value="Update">

   
   
  </form>

]Row 91 is:

Code:

<p>Total value ROW:  <b> <input type="hidden" name="amount" value="0"><?php echo $myCart->format_value($val['price'] * $val['quantity']); ?></b></p>

Any ideas?

not sure what you're doing but the variable doesn't exists:

$val['quantity']

I guess I don't understand because $val('quantity) is in db_cart example.php where this code is. What I did was just took the $val("quantity) out of the table and installed it in the label section above.

What I want it to do is like the checkout have it to do update per line and also give you the total of the line or row.

I have the db_cart example.php having an update button and recalculating like the checkout.  The only thing is that when you first enter the different number in the update button it brings up another product line with no info on it with $0 price with the same quantity you entered in the update button.  How do I get it so it doesn't bring up another product line?

This is still not what I really looking for it's like http://www.debmoe.com/slidesorderform.html but I want it in php and on mysql.

The changes I made was in the db_cart example: I added after new db_cart: // update a single order row
if (isset($_POST['add']) && $_POST['add'] == "Update") {
   $myCart->update_row($_POST['row_id'], $_POST['quantity']);
}

and replaced the table with: <table>
  <tr>
    <th>Art. no.</th>
    <th>Product</th>
   <th>Price</th>
   <th>Amount</th>
   <th>Quantity</th>
  </tr>
  <?php foreach ($myCart->order_array as $val) { ?>
  <tr>
    <td><?php echo $val['product_id']; ?></td>
   <td><?php echo $val['product_name']; ?></td>
   <td align="right"><?php echo $myCart->format_value($val['price']); ?></td>
   <td align="right"><?php echo $myCart->format_value($val['price'] * $val['quantity']); ?></td>
   <td>
      <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
       <input type="hidden" name="row_id" value="<?php echo $val['id']; ?>">
       <input type="text" name="quantity" size="5" value="<?php echo $val['quantity']; ?>">
       <input type="submit" name="add" value="Update">
      </form>
   </td>
  </tr>
  <?php } // end foreach loop ?>
</table>

do you called this function?

$myCheckout->show_ordered_rows();

No in db_cart example it's Called  $myCart.  I tried $myCheckout and I get the error:  to a member function on a non-object in mypathway on line 35
