PayPal code works until I add prices for options? - html

Question

Not sure what to ask exactly but I've followed the instructions on the PayPal Developer site:
https://developer.paypal.com/docs/classic/paypal-payments-standard/integration-guide/buynow_buttons/
have another question though. I have a form:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_xclick">
<input type="hidden" name="business" value="myemail#myaddress.com">
<input type="hidden" name="bn" value="MR_BuyNow_WPS_CA">
<input type='hidden' name='lc' value='CA'>
<input type="hidden" name="currency_code" value="CAD">
<input type="hidden" name="no_shipping" value="0">
<input type="hidden" name="no_note" value="1">
<input type="hidden" name="return" value="/design/payments/success/">
<input type="hidden" name="cancel_return" value="/design/payments/failed/">
<input type="hidden" name="cbt" value="Return to MR">
<input type="hidden" name="item_number" value="buy-time">
<table>
<tr><td>
<p>Provide the following:</p>
</td></tr>
<tr><td>
<div class="row collapse">
<div class="small-3 columns">
<span class="prefix"><span data-tooltip aria-haspopup="true" class="has-tip" title="Please provide your full name as it appears on the order form.">Name:</span></span>
</div>
<div class="small-9 columns">
<input type="text" placeholder="What is your name?" name="os0" maxlength="200">
</div>
</div>
<div class="row collapse">
<div class="small-12 columns">
<select name="item_name">
<option value="Maintenance Hours">Maintenance</option>
<option value="General Work Hours">General Work (Additions, etc.)</option>
</select>
</div>
</div>
<div class="row collapse">
<div class="small-12 columns">
<select name="os1">
<option value="2 Hours ($50/Hour)">2 Hours ($50/Hour) - $100.00 CAD</option>
<option value="3 Hours ($45/Hour)">3 Hours ($45/Hour) - $135.00 CAD</option>
<option value="4 Hours ($45/Hour)">4 Hours ($45/Hour) - $180.00 CAD</option>
<option value="5 Hours ($45/Hour)">5 Hours ($45/Hour) - $225.00 CAD</option>
<option value="6 Hours ($45/Hour)">6 Hours ($45/Hour) - $270.00 CAD</option>
</select>
</div>
</div>
</td></tr>
</table>
<input type="hidden" name="on0" value="Client">
<input type="hidden" name="on1" value="Hours">
<input type="image" class="payments-buy" src="http://mrobertsdesign.ca/img/payments_buy.png" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
</form>
Now it technically works (it at least goes through to the paypal purchase page) until I actually add the prices for the buttons:
<input type="hidden" name="option_select0" value="2 Hours">
<input type="hidden" name="option_amount0" value="100.00">
<input type="hidden" name="option_select1" value="3 Hours">
<input type="hidden" name="option_amount1" value="135.00">
<input type="hidden" name="option_select2" value="4 Hours">
<input type="hidden" name="option_amount2" value="180.00">
<input type="hidden" name="option_select3" value="5 Hours">
<input type="hidden" name="option_amount3" value="225.00">
<input type="hidden" name="option_select4" value="6 Hours">
<input type="hidden" name="option_amount4" value="270.00">
If anyone with any experience could point out something I'm missing that would be great =)

Answer 1

I'm not entirely sure what your goal is, but would it be easier to use PayPal's built in use of dropdowns for a button? Since you are basically saying that the hourly rate is discounted you could use a buy now button that is set for $50 and if they choose a quantity of 3 or more it is discounted to $45. Hope this helps.

Answer 2

It turns out that the value of ABC in <option value="A">, <input type="hidden" name="option_selectX" value="B">, and <input type="hidden" name="option_amountX" value="C"> must (1) not contain any capitals, special characters or spaces, (2) it also must either be alphanumeric or contain at least one letter, and (3) be one whole phrase:

This is strange to me because the value of <option value="A"> could include spaces before I included <input type="hidden" name="option_selectX" value="B"> and <input type="hidden" name="option_amountX" value="C">.
Took me a little while of trial and error to figure this out.
