You need to develop a small quantity price override plugin. We have some documentation on that in our developer documentation: [ www.hikashop.com/support/support/documen...tation.html#override](http://www.hikashop.com/support/support/documentation/62-hikashop-developer-documentation.html#override) And you'll find an example of such price override plugin with the donation plugin: [ demo.hikashop.com/index.php?option=com\_h...show&cid=214&lang=jp](http://demo.hikashop.com/index.php?option=com_hikashop&ctrl=product&task=show&cid=214&lang=jp) 2. In your second custom field options screen, you can select your first custom field's "yes" value in the option "Display limited to". That way, the second field will only display when the first one is set to "yes".

The custom field is easy as item and text with name amount. Do you have a code example for the price that will depend of the amount of characters in a custom field. Say each character will cost 1,-. I'am trying to find my way, but this is new for me.

The donation plugin file path is plugins/system/custom_price/custom_price.php There you can just add such line: $product->amount = strlen($product->amount); after the line: if(!empty($product->amount)){ and it should work like you want.

I have added 2 screenshots, one with the definition of the custom field and the other one with the result of the product page. On the product page you see in the attachement shows the custom field 'amount' with value 'John'. 'John' has 4 characters and i like to add 4 times 1,- => 4,- to the base price of 7,95. The total result should be 11,95, but it stays at the 7,95. I hope you can help me further with this.

I have set the extra line $product->amount = strlen($product->amount); in the php file custom_price.php as you have told me behind the line if(!empty($product->amount)){ . I showed you both definition screens. No change of my price is seen in the product page were the custom field and the prices are included. In the cart no change is seen. When we go on with checking out the price stay the same and no change is noticed.

Now i want to add this to the normal product price. The product has a price set in the product definition. The name to add to the product is extra and must be added upon the product price. Example the product is 7,95 and the name (JOHN) that must be added has 4 characters. The total price must be 7,95 + 4 = 11,95. Now the result is 4,- instead of 11,95. Hope you can clear this up for me too.

Regards, Anita")* Hi, To do so, you first need to create an "custom item field" for the product category you want to affect the name selection by the user. Then, you will need to duplicate the plugin "system / custom price" also called the "donation plugin". This plugin force a product price depending an "item custom field" called "amount" ; in your case you want another algorithm for the price calculation, so you will need (or a developer) to write it. Because it is a specific algorithm, it will result a custom plugin. The development of such plugin require some PHP/Development knowledge. The idea of your custom plugin is not to override the product price but to add a determined price to the original product price ; like a dynamic fee depending the value of an item custom field. And if there is not item custom field for the product (or empty), you can simply exist the function without modifying the product object.

Regards, Anita")* Dear all, 1) I have changed the php code is the way i have documented in the file attached here. Is this what you meant? I created a new variable called $amount that holds the number of chars times 1. That variable is added to the product price. Now i have the amount calculated and the name for the ordering too. That worked well i think. 2) My second question is that the amount of characters now is multiplied by 1. Can i enter a price per character say 0,50 cents instead of 1 cent. I can add it direct in code that works. However i like to have a field in the product definition were i can add the price per character. How can i add a field in the procuct definition for the purpose. 3) Can i use a characteristic as variant to decide to show a custom field or not. I like to show the custom item field "amount" when the variant is YES and i like to hide when the variant is NO. Can you check it for me.

Regards, Anita")* Hi, More or less yes. Some parts are good but I see some little "mistakes". The best will be to just replace the first line you modified by Code: $my_amount = strlen($product->amount); And then Code: foreach($product->prices as $k => $price){ $product->amount = $product->prices[$k]->price_value + $my_amount; So for the rest of the price assignations, the product->amount will be used correctly. You can put a category filtering on the custom item field. So you can use an hidden HikaShop category to regroup all product affected by the item custom field.

When i have a name of 4 characters (john) and the base price = 7,95 i see in the end price of the product is 7.95 + 3 euro = 10.95 and the total = 11.95. This is strange because it should be the same price. The name is not "john" anymore but someting as 10.795. I need to have the name "john" in the order to have the information so we can add the name to the product. 10.795 is not that what we can use. My solution likes to work better. I am puzzeling why your solution is having this effect. I hope you can explain this for me. You are the expert. Can you make chocolate of this..?? I can't. I like to know were we are going wrong.
