How to add combinations to products in PrestaShop 1.5-1.6
If you want to create different variations of the same product, you can do that by combining product attributes. In this way you don't have to add each variant of the same product as a separate product, but you can combine product attributes (e.g. color, size, etc.) to create variations of a single product. On the product page on the frontend customers can select a combination by using the options that are provided there.
You can add and manage combinations from the Combinations tab that's on the left side of the form for adding/editing products. You can do it manually or you can use a product combinations generator. In this article we'll briefly go over both ways.
For general information on adding and editing products check the tutorial on how to add and manage products in PrestaShop, or the shorter article version.
Create Product Combinations Manually
To create a product combination, go to Catalog menu>Products sub-menu in the admin panel, edit the particular product and on its edit form click on the Combinations tab on the left. On the page that opens click on the button New combination. This will display the options for adding and managing product combinations. At the top of the page there are a couple of drop-down menus labeled Attribute and Value. From the Attribute drop-down menu select the particular attribute group (e.g. color) and from the Value drop-down menu you can select one of the values in that group (e.g. black, green, blue, etc.). Then click on the Add button. The value will be listed in the text area below the drop-down menus. If you want to, you can add more attributes to this combination. However you cannot add two values from the same attribute group. Note that you can only choose from the existing attributes and values. They can be added and manage from Catalog menu>Product Attributes sub-menu in the admin panel.
Under the options for the attributes there's a setting for reference code which, if you want to, you can use to specify some reference code for internal use. Below it there are a couple of barcode settings. They are also optional and you can use them to specify the barcode digits of the product. Use the option that corresponds to the barcoding system used for your product.
If the wholesale price of the combination is different than the base one that you configured from the Prices tab on the left, type it in the field Wholesale price. Otherwise, leave it to 0. If the price and weight of the product combination are different than the basic settings for the product, you can use the respective drop-down menus to configure the impact on the price and the weight. There's also an option for the minimum quantity that customers have to order from that product combination.
Under these options you can select one or more of the uploaded product images to be associated with the product combination. Product images for all combinations can be uploaded from the Images tab on the left. If you want the combination to be the default one, mark the Default checkbox at the bottom of the page.
When you're done with the options click on the Save and stay or on the Save button to add the combination. It will be listed in a table on the same page.
Product Combinations Generator
You can use the combinations generator to automatically generate all the possible combinations from a set of product attributes. To do this, on the add/edit product form click on the Combinations tab on the left and on the page that opens click on the link Product Combinations Generator. It's at the top of the page.
The available attributes will appear in a panel on the left. Press and hold the Ctrl button on your keyboard and with the left mouse button mark the attributes that you want to use. Then click on the Add button that's under the panel with the attributes. All the selected attributes will be listed on the right. In the respective fields you can configure the price and weight impact for each attribute. Below these fields there are a couple of options with which you can set a default quantity and default reference for all combinations. After they are created you can edit the quantity and reference of each combination. When you're done with the options click on the button Generate these combinations.
Edit and Delete Product Combinations
When you click on the Combinations tab on the form for adding/editing products all the combinations of the product are listed in a table. You can edit a combination by clicking on its Edit button in the table (in PrestaShop 1.5 the button is not labeled; it looks like a small pencil). To delete a combination or make it the default, click on the arrow that's next to its edit button and from the drop-down menu select the respective action. In PrestaShop 1.5 there's no such drop-down menu; the delete button looks like a trash can, and the one for making the combination the default one looks like a star.
Product Combinations Quantities
The quantities of the product combinations are not managed from the Combinations tab but from the Quantities tab. There you'll see a list of all the combinations of the product. For each combination there's a field in which you can type its quantity.
