How to add product & coupon to cart with a link?

I cleared the cart and cleared the browser cookies and cache, and now the link adds the product & coupon to the cart, but gives warnings on the cart page – 2 warnings that I cannot add this product again to the cart & 1 warning that the coupon code was already applied.

It seems that using this link, it tries to add the product 3 times and the coupon 2 times…

Here is the image of what I get on the cart page when I use the link:

Hi Nichelead,

I think it has to do with redirects. If I go to
https://yoursite.com/cart/?add-to-cart=1264&apply_coupon=freeguide-sywtm

it immediately redirects to the /checkout/ page, what causes this? Can you try disabling this redirect?

Hi,

Thanks for getting back to me.
Yes, there was a redirect to checkout and I disabled it.
It is not redirecting anymore, but still give these warnings.

Ok, I found the issue. Two things.

If I use this url:

https://yoursite.com/cart/?add-to-cart=1264&apply_coupon=freeguide-sywtm

it seems fine at first call, but if I use this url instead:

https://yoursite.com/cart?add-to-cart=1264&apply_coupon=freeguide-sywtm
(notice the trailing slash removed after /cart)

I get the warnings. This is because of another redirect. So, you have to use the first url.

…

Ok, so far so good using the first url. But opening the cart for a second time it will shows the warning ‘coupon already applied’ on the second call. The reason seems to be the minicart, the minicart is called by ajax with &apply_coupon=… as well. This could be a quick fix:

In includes/wjecf-autocoupon.php please find this line (line 35 if you use the latest version):

add_action( 'wp_loaded', array( &$this, 'coupon_by_url' ), 23);

and replace with:

if ( ! is_ajax() ) {
	add_action( 'wp_loaded', array( &$this, 'coupon_by_url' ), 23); //Coupon through url
}

This should fix it. I will patch this in a following release of my plugin.

Works Perfect!

Thank you!

Excellent!

Thanks for rating my plugin!

Hi Josk79,

So, one more little hiccup…

After I disabled the plugin that redirected from Buy button strait to checkout (skipping the cart), I realized that my Add To Cart Button didn’t directed to the cart.

It was a Woocommerce setting that I didn’t use while I was using that checkout redirect plugin.

So to fix this now, I went to Woocommerce, Settings, Product Tab, Display Sub-Tab, “Add to cart behavior” and checked “Redirect to the cart page after successful addition”.

That fixed the problem, so now the Add To Cart Button redirect to the Cart.

But – now I get again a “You cannot add another product…” warning when using the link to add product & coupon.

Thanks!

Tom

Does enabling my plugin cause the issue? Even without an apply_coupon request? Can you send me a link that causes the issue?

Did you disable my plugin? I want to try it out but the coupon doesn’t seem to exist anymore and apply_coupon does nothing.

Sorry, I changed the coupon and forgot to mention. here is the new coupon:
freeguide-syw

I think my plugin is disabled, so I can’t test.

Also I don’t see any issues, maybe because you disabled my plugin?

Your plugin is not disable.

Try this link.
https://successgoose.com/cart/?add-to-cart=1264&apply_coupon=freeguide-syw

For me, it just adds the product – not the coupon.
If after using this link once, I use it again, without empty the cart, it will now add the coupon (just with warning notice “You cannot add another product…”.
The problem is that the first time I use the link it doesn’t add the coupon.

I see, the redirection to the cart disables the handling of apply_coupon. I’ll have to look into that…

I’ll get back to you later this week.

Thank you!

If you have PHP >= 5.3 can you please try adding these lines in your theme’s function.php?

Or you can place it in wjecf-autocoupon.php before the if ( ! is_ajax() ) { you added.

add_filter('option_woocommerce_cart_redirect_after_add', function( $value ) {
	if ( isset( $_GET['apply_coupon'] ) ) {
		$value = 'no';
	}
	return $value;
} );

and let me know if it works then? This should disable the cart redirect if apply_coupon is passed in the url.

You’re the man!

I added it to wjecf-autocoupon.php – I assume you will patch it in the plugin update so I don’t need to worry about loosing these changes
