title: submitting multiple items to paypal cart at once with php
body: <p>I have some items for sale that have 2 and 3 levels of customization. Once set the user adds them to my onsite cart. Problem is, how can i send each item to paypal on checkout? The only code ive found for dynamic buttons supports only a single item.</p>
  
  <pre><code>&lt;form method="post" action="https://www.paypal.com/cgi-bin/webscr" target="paypal"&gt;
  &lt;input type="hidden" name="cmd" value="_cart"&gt;
  &lt;input type="hidden" name="add" value="1"&gt;
  &lt;input type="hidden" name="business" value="EMAIL"&gt;
  &lt;input type="hidden" name="item_name" value="Item #1"&gt;
  &lt;input type="hidden" name="item_number" value="123456"&gt;
  &lt;input type="hidden" name="amount" value="7.00"&gt;
  &lt;input type="hidden" name="shipping" value="0"&gt;
  &lt;input type="hidden" name="shipping2" value="0"&gt;
  &lt;input type="hidden" name="handling" value="0"&gt;
  &lt;input type="hidden" name="currency_code" value="USD"&gt;
  &lt;input type="hidden" name="return" value="http://www.yoursite.com/thankyou.htm"&gt;
  &lt;input type="hidden" name="undefined_quantity" value="1"&gt;
  &lt;input type="image" src="http://images.paypal.com/en_US/i/btn/x-click-but22.gif" border="0" name="submit" width="87" height="23" alt="Make payments with PayPal - it's fast, free and secure!"&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>I tried adding</p>
  
  <pre><code>&lt;input type="hidden" name="item_name_2" value="Item #1"&gt;
  &lt;input type="hidden" name="item_number_2" value="123456"&gt;
  &lt;input type="hidden" name="amount_2" value="7.00"&gt;
  </code></pre>
  
  <p>But no positive result.</p>
  
  <p>Any ideas?</p>
