simplecart:need to pass another params on checkout
<p>I need to pass item id through checkout on custom form. Here is item add </p>

<pre><code>&lt;div class="simpleCart_shelfItem"&gt;
  &lt;div class="ju_cntr" style="width:350px"&gt;
    &lt;input type="hidden" class="item_id" name='tratata' value="asfd2"&gt;
    &lt;div class="juice_hd item_name" style="width:350px"&gt;
       test2
    &lt;/div&gt;
    &lt;div class="juice_pic" style="width:350px"&gt;
      &lt;img class="item_thumb item_image item_add" src="/images/upload/9174.jpg"/&gt;
    &lt;/div&gt;
    &lt;div class="juice_txt"&gt;
      &lt;span class="item_price"&gt;$123.00&lt;/span&gt;&lt;input type="text" value="1" class="item_Quantity"&gt;&lt;a class="item_add" href="javascript:;"&gt; Add to Cart &lt;/a&gt;
    &lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>and result on checkout</p>

<pre><code>Array
(
    [currency] =&gt; USD
    [shipping] =&gt; 0
    [tax] =&gt; 0
    [taxRate] =&gt; 0
    [itemCount] =&gt; 2
    [item_name_1] =&gt; 
                                            123                                     
    [item_quantity_1] =&gt; 7
    [item_price_1] =&gt; 123
    [item_options_1] =&gt; 
    [item_name_2] =&gt; 
                                            test2                                       
    [item_quantity_2] =&gt; 6
    [item_price_2] =&gt; 123
    [item_options_2] =&gt; 
)
</code></pre>
