Hi!

I'm developing a PayPal button plugin using the following code:

1. class paypal_button
2. {
3.   function show( $business='default@mail.com', $item_name='Default item', $amount=1 ) {
4.     $html = '<form action="paypal.com/cgi-bin/…;
5.              <input type="hidden" name="cmd" value="_xclick">
6.              <input type="hidden" name="business" value="' . $business . '">
7.              <input type="hidden" name="lc" value="ES">
8.              <input type="hidden" name="charset" value="utf-8">
9.              <input type="hidden" name="item_name" value="' . $item_name . '">
10.              <input type="hidden" name="amount" value="' . $amount . '">
11.              <input type="hidden" name="currency_code" value="EUR">
12.              <input type="image" src="paypalobjects.com/es_ES/ES/i/btn/…;
13.              </form>';    
14.   return $html;
15.   }
16. }

But, for some reason if I call the plugin with no parameters:

<plugin:paypal_button:show />

the $business parameter is empty instead of using the default value.

Any ideas of what might be going on here?

You're close...like this...

1. <plugin:class_name:method param='hi','yes',more='like that' />

Personally, I feel that the email addresses should be either baked into the script or set via options. I wish I could write this tutorial right now but I'm a bit hung up with christmas already.

;)

So, all parameters are required in the plugin call?

Yes and no.

The first two, class name and method, yes. The others are optional.

If you must, you can simply use a function (not OOP) and call it thusly:

1. <plugin:function_name parmeters='optional' />

This allows for some old plugins to work.
