"Undefined index" errors on: July 19, 2012, 11:01

Hi
I installed the paypal cart 4.3.3 to Wordpress 3.4.1.

I immediately got these errors printed at the top of every page:

Notice: Undefined index: addcart in /var/www/web/wse64536/kiwiembedded.com/wp/wp-content/plugins/wp-ultra-simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.php on line 86

Notice: Undefined index: quantity in /var/www/web/wse64536/kiwiembedded.com/wp/wp-content/plugins/wp-ultra-simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.php on line 133

Notice: Undefined index: delcart in /var/www/web/wse64536/kiwiembedded.com/wp/wp-content/plugins/wp-ultra-simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.php on line 146

When I add 'add to cart' button I get even more errors.

Notice: Undefined variable: post in /var/www/web/wse64536/kiwiembedded.com/wp/wp-content/plugins/wp-ultra-simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.php on line 537

Notice: Trying to get property of non-object in /var/www/web/wse64536/kiwiembedded.com/wp/wp-content/plugins/wp-ultra-simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.php on line 537

Notice: Undefined index: 1 in /var/www/web/wse64536/kiwiembedded.com/wp/wp-content/plugins/wp-ultra-simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.php on line 486

Suggestion?

There is approximately 25 places in the code that will raise these notices. Note that these are not fatal errors, just warnings. Disabling the PHP error reporting will suppress the notices.

In my case, I am developing a companion plugin and I need the error display enabled. So I worked my way through the code and resolved each notice. For example, here is one fix to the undefined index on line 87 raised when the plugin is activated.

	// 08/21/12 mophilly; step around empty $post
	if (empty($post)) {
		$permlink = '';
	} else {
		$permlink = get_permalink($post->ID);
	}

I hope this helps.

Thanks Mophilly,

I add your permlink test to avoid notice on get_permlink.
For other notice I'm not perfect, maybe one day i will code without any , but now I'm more focused on error.
