option for Tip amount

Is there a way I can add an option in marketpress where the buyer can add a tip amount in the shopping cart for my local delivery?

    I started digging through the code and found where to add a “Tip” area and then as I was looking for how to allow the update cart to add this to the total I thought of the easiest answer for you – add a product called TIP with a cost of $1. Then someone can add as much as they like.

    You’ll probably want to add the tip product in the widget area or do some custom code to always add that product to the cart.

    Hope that helps!

    Thank you digitsoft :slight_smile:

    I didn’t know I can add new product with an open price, in this case tip amount? But even if I did it, I have to be able to add this product ” tip” to checkout page before payment?

    Just create a product that “costs” $1 and name it Driver Tip, but you’re correct – you’d need to do some custom coding to always add that product to the checkout screen.

    It’s not an open price, but rather a fixed price of $1 that the buyer can add multiple quantities of.

    Example – if they wanted to tip $10, then they’d change the quantity to 10 instead of 1.

    Here’s a quick solution:

    1. Create a “Tip” product and maybe give it variations of “Thanks” $1, “Big Thanks $2, “Wow” $5 (these would display in the product listing as a drop down)

    2. In each product that you want to add a tip option add this at the bottom of the product in html mode:


    Add a tip: [mp_buy_button product_id=”94″ context=”single”]


    The product_id would need to be changed to the tip product you created in #1.

    I tested this and it works…

    Hi digitsoft,

    It WORKS!!!!!!!! It WORKS!!!!!!!! It WORKS!!!!!!!! It WORKS!!!!!!!! It WORKS!!!!!!!! It WORKS!!!!!!!! It WORKS!!!!!!!! . Thank you very much for your help :slight_smile:

    I did some change to it but I kept the same idea you gave me. Instead of adding it to every product. I just put a message on the shopping cart with a link to the tip product with an image :slight_smile:

    Now I have a last question for you, and I swear it's the last one :slight_smile::

    Is there a way I can change the flat rate for the shipping to a percentage instead of $ amount. I want to make it 15% to all products.

    And again you have been very helpful.

    Cool….glad it worked for you!

    Here’s how to do a flat % in a round about way:

    1. Open wp-content/plugins/marketpress/marketpress-includes/plugins-shipping/mp-table-rate.php in an editor

    2. At line 323 (or so) above where it says “return $price;” add these 2 lines:

    $percent = .15;

    $price = $total * $percent;

    It should look like this now:

    $percent = .15;

    $price = $total * $percent;

    return $price;

    3. Set your shipping to flat rate, enter a 1 in each, and you’re done.

    I did a quick test and it worked, but you’ll want to verify.

    LMK if this solves it for you…

    I took this one step further…mainly as a personal challenge to see if I could do it and after an hour or so I was able to create a working shipping percentage plugin :slight_smile:

    Just unzip it and put the php file in this dir: /wp-content/plugins/marketpress/marketpress-includes/plugins-shipping

    It will automatically find the shipping option after you click the Shipping tab again.
