Display specific line item

4/28/2011 9:17 am | #1 Dave BuchholzBeta Tester

Is there a method I can access where I can define a single line item to display for modification purposes in the following general scenerio ?

My cart object is eCart1 as standard.

I have 3 products in my cart and I want to modify my order for the 2nd product, so I click on a link that sends me to another page where that product along with it's options are displayed for updating.

I am guessing I need to pass the product id and display index ($eCart1->DisplayIndex) but how do I tell the cart object to only display that line or access the individual columns from that line to prepopulate the page ?

Thanks.

if you are not using any product options, you could pass only the ID as a querystring variable to standard cart display page. And add an if statement.

So the link would look like:
ItemUpdate.php?id=2

and in the cart display code, change the while loop:

php:

<?php

while (!$eCart1->EOF())      {

?>

          <tr>

            <td  class="eC_GroupColumn"><img  src="<?php echo $eCart1->DisplayInfo("Thumbnail"); ?>" alt="Product thumbnail" class="eC_ProductThumb" />

              <p class="eC_ItemName"><?php echo $eCart1->DisplayInfo("Name"); ?></p>

              <p class="eC_ItemDescription">Description:&nbsp;<?php echo $eCart1->DisplayInfo("Description"); ?></p></td>

            <td  class="eC_PriceItem"><?php echo WA_eCart_DisplayMoney($eCart1, $eCart1->DisplayInfo("Price")); ?></td>

            <td  class="eC_FormItem"><input type="text" name="eCart1_Quantity_<?php echo $eCart1->DisplayIndex; ?>" size="3" value="<?php echo $eCart1->DisplayInfo("Quantity"); ?>" /></td>

            <td  class="eC_FormItem"><input type="checkbox" value="<?php echo $eCart1->DisplayInfo("ID"); ?>" name="eCart1_Delete_<?php echo $eCart1->DisplayIndex; ?>" /></td>

            <td  class="eC_PriceItem"><?php echo WA_eCart_DisplayMoney($eCart1, $eCart1->DisplayInfo("TotalPrice")); ?></td>

          </tr>

          <?php

  $eCart1->MoveNext();

}

$eCart1->MoveFirst();

?>

add an if statement to compare the id querystring:

php:

<?php

while (!$eCart1->EOF())      {

?>

<?php if(isset($_GET) && $_GET['id'] == DisplayInfo("ID")) { ?>

          <tr>

            <td  class="eC_GroupColumn"><img  src="<?php echo $eCart1->DisplayInfo("Thumbnail"); ?>" alt="Product thumbnail" class="eC_ProductThumb" />

              <p class="eC_ItemName"><?php echo $eCart1->DisplayInfo("Name"); ?></p>

              <p class="eC_ItemDescription">Description:&nbsp;<?php echo $eCart1->DisplayInfo("Description"); ?></p></td>

            <td  class="eC_PriceItem"><?php echo WA_eCart_DisplayMoney($eCart1, $eCart1->DisplayInfo("Price")); ?></td>

            <td  class="eC_FormItem"><input type="text" name="eCart1_Quantity_<?php echo $eCart1->DisplayIndex; ?>" size="3" value="<?php echo $eCart1->DisplayInfo("Quantity"); ?>" /></td>

            <td  class="eC_FormItem"><input type="checkbox" value="<?php echo $eCart1->DisplayInfo("ID"); ?>" name="eCart1_Delete_<?php echo $eCart1->DisplayIndex; ?>" /></td>

            <td  class="eC_PriceItem"><?php echo WA_eCart_DisplayMoney($eCart1, $eCart1->DisplayInfo("TotalPrice")); ?></td>

          </tr>

<?php } ?>

          <?php

  $eCart1->MoveNext();

}

$eCart1->MoveFirst();

?>

yeah, that's why I started off saying:
if you are not using any product options

Since you are using options, how do you want to handle the option?

Will the options be updatable?

if you want the option to be updatable, the pass the option as a quersyring variable too:

ItemUpdate.php?id=2&color=red

go to the bindings panel and click the plus button, select URL Variable an name it "option"
then in design view for the cart display, select the option column and insert an eCart editable Select list. Insert -> Webassist -> eCart -> Updatable List

in the property inspector for the list, click the dynamic button, set the static values for the list of available options, then click the lightning bolt next to Select Value Equal to and select the option querystring variable.
