SIM line item integration

k2 — Mon, 05 Mar 2012 22:56:37 GMT

I've searched the forums for help on getting line item data to display via SIM method. I've been able to hardcode the data in and it works just fine, but I need to pull from the shopping cart as it is obviously going to be dynamic and possibly have multiple items.

So far this is what I have come up with that works to display one item, but not multiple...

<input type='hidden' name="x_line_item" value="<?php echo $prodslistpostID; ?><|><?php echo $prodslistitem; ?><|><|><?php echo $prodslistquantity; ?><|><?php echo $prodslistamount; ?><|>Y" />

Any help would be amazing.

Here's some code I hacked together quickly. This simulates an array of two items.

<?php
$items = array(
    array(
        'id' => 'ID1',
        'name' => 'Product Name 1',
        'description' => 'Product Description 1',
        'quantity' => 1,
        'price' => '9.99',
        'taxable' => 'Y'
    ),
    array(
        'id' => 'ID2',
        'name' => 'Product Name 2',
        'description' => 'Product Description 2',
        'quantity' => 1,
        'price' => '4.99',
        'taxable' => 'Y'
    )
);

foreach ($items as $item) {
    $line_item = array();
    foreach (array('id', 'name', 'description', 'quantity', 'price', 'taxable') as $key)
        $line_item[] = $item[$key];
    print '<input type="hidden" name="x_line_item" value="' .
          implode('<|>', $line_item) .
          '">' . "\n";
}
?>

Thanks for your help TJ. I think this is getting towards what I need, but not there yet. Basically, I need something that can pull items that have been added to the shopping cart and then post them to the Authorize.net hosted checkout page. This could be anywhere from 1 item to 30 items (so I would need the arrays to generate dynamically as well). I'm using Wordpress with MarketTheme if that helps any.

If you can do a print_r() of the item array from your cart, I can maybe write something to adapt that for you.

Here is what I got. Thanks again.

Array ( [423] => Array ( [postID] => 423 [quantity] => 1 [shipping] => 4.95 [shipping2] => 0 ) [368] => Array ( [postID] => 368 [quantity] => 1 [shipping] => 4.95 [shipping2] => 0 ) ) Array ( [423] => Array ( [postID] => 423 [quantity] => 1 [shipping] => 4.95 [shipping2] => 0 ) [368] => Array ( [postID] => 368 [quantity] => 1 [shipping] => 4.95 [shipping2] => 0 ) )

It's more helpful to view source so it's indented properly, and did you paste or output the same thing twice?

But in any case:

<?php
$items = Array( 
	'423' => Array( 
		'postID' => 423,
		'quantity' => 1,
		'shipping' => 4.95,
		'shipping2' => 0,
	),
	'368' => Array( 
		'postID' => 368,
		'quantity' => 1,
		'shipping' => 4.95,
		'shipping2' => 0
	)
);

foreach ($items as $item) {
    $line_item = array();
    
    if (!$item['taxable'])
        $item['taxable'] = 'Y';

    $item['price'] += $item['shipping'] + $item['shipping2'];
    
    foreach (array('postID', 'name', 'description', 'quantity', 'price', 'taxable') as $key)
        $line_item[] = $item[$key];

    print '<input type="hidden" name="x_line_item" value="' .
          implode('<|>', $line_item) .
          '">' . "\n";
}
?>

Outputs:

<input type="hidden" name="x_line_item" value="423<|><|><|>1<|>4.95<|>Y">
<input type="hidden" name="x_line_item" value="368<|><|><|>1<|>4.95<|>Y">

You ought to be able to take it from here. If not, study the PHP manual:

Unfortunately I'm still not any closer. I'm sure I didn't explain my problem well. Below is the code from my shopping cart. Somehow I need to grab the line item info from here and post it to the authorize.net form.
