The price display feature allows to show important information on a product including price, product name, legal notice as well as the product information via an info icon button. Reduced or special-offer prices are also possible to display.
Pro Tip: A working price display code example can be created in every template by using the Generate Embed Code function in the editor for every template.
There are multiple ways to setup price categories or price tags in the editor. Group and layout snippets can have price categories from 1 to 5. Documents can have a named price category and form-fields different price-tags.
When creating layout snippets or stickers go to the “Snippet Export” section. Here one can choose a price category between one and five. These categories will be used to allocate a price label via the snippetPriceCategoryLabels attach parameter. Labels are displayed as a badge on each categorized snippet.
Form-field price labels can be set for select-list, image-list and color-list form-fields. It is important to mark them as Price Relevant to see results. Price-tags can be set in the column tag (price-category). Same like for snippets you need to set the respective labels in the attach parameters. For form-fields and documents it is the priceCategoryLabels. One can give any random named tag to the list items. To see a price label in the buyer side, the tag needs to match a key in the priceCategoryLabels attach parameter.
In the attach parameters one can add the customized labels for the different categories and price tags set in the editor. Also the priceChangeCallback needs to be added to handle price changes and to update the price display.
As mentioned snippets have a price category from 1 to 5. In the same order from one to five one needs to add an array of strings for the respective categories as follows:
/* Labels displayed at stickers which have a price categorie-number set */
snippetPriceCategoryLabels: ["+ 1.50 €", "+ 2.50 €", "+ 3.50 € ", "+ 4.50 €", "+ 5.50 €"]
Hereby, the labels are just an example, where snippets with category 1 would get a price badge of “+ 1.50 €” and snippets with category 5 a price badge of “+ 5.50 €”.
Form-field labels will be added via the priceCategoryLabels attach parameter, which is of type Record<string, string>. In the following example, if an item from a select list has the tag “mug-back” then it will receive a badge with the label “+ 2.10 €” on it.
/* Labels displayed at form-fields which have a price tag set */
priceCategoryLabels: {
"mug-front": "+ 2.10 €",
"mug-back": "+ 2.10 €"
}
After setting up the editor and code and then choosing a snippet or changing a price relevant form-field in the buyer side, a priceChangeCallback will be fired. It returns the parameter priceInfo which has all the relevant information one needs for calculating the new price displayed beside the basket button.
If now for example the two-sided mug variant was selected from the list, a priceChangeCallback will be thrown and the following priceInfo will be returned:
{
priceCategories: ["mug-back"],
priceRelevantFormFields: {
MugVariants: {
tag: "mug-back",
value: "two-sided"
}
},
snippetPriceCategories: [
{
priceCategory: 2,
amount: 1
},
{
priceCategory: 4,
amount: 1
}
],
testModeEnabled: false
}
Whereas the priceCategories contain an array of tags that were selected via the form-field lists. The priceRelevantFormFields store information about selected items from price-relevant form-field lists with its value and tag (price-category). And the snippetPriceCategories return the number of times snippets of each price category were used.
The above information can be used to calculate and display a new price to the user. To do so, an object with the new price information has to be put as a parameter when calling the uiHelper.refreshPriceDisplay function, which updates the price display in the buyer side.
{
price: "11.90 €*",
legalNotice: "*Inkl. VAT plus shipping",
productName: "Coffee Mug",
oldPrice: "14.60 €",
infoUrl: "https://product-info.com"
}
Overall, the priceChangeCallback could look as follows in the iframe callback:
/* **************************** */
/* listen to printess callbacks */
/* **************************** */
window.addEventListener("message", () => {
switch (event.data.cmd) {
case "back":
// Back to catalog. Data: event.data.token
break;
case "basket":
// Proceed to checkout. Data: event.data.token + event.data.thumbnailUrl
break;
case "priceChanged":
/*
** set price based on priceInfo **
** Prices for snippets and price categories
** need to come from your shop
** not used parameters can be left out
*/
const sampleData = {

// ** calculate snippet prices
const snippetPrice = event.data.priceInfo.snippetPriceCategories.map(pc => (sampleData.snippetPrices[pc.priceCategory] || 0) * pc.amount).reduce((p, c) => p + c, 0)
// ** calculate price categories
const categoriesPrice = event.data.priceInfo.priceCategories.map(dc => (sampleData.priceCategories[dc] || 0)).reduce((p, c) => p + c, 0);
// ** get base Price
const basePrice = sampleData.basePrice;
const r = {

legalNotice: sampleData.legalNotice,

}
// THIS WILL SET THE PRICE AND INFO DISPLAY
// ** Set price display in printess

Legal Notice: The
legalNoticeparameter supports markdown syntax for links. So you can insert links to your legal or shipping site if you want. Just use[Link Title](https://www.printess.com)
To conclude, there are three steps to take when setting up a price display. You need the attach parameters [“priceChangeCallback”, “snippetPriceCategoryLabels”, “priceCategoryLabel”] - labels depend on your requirements. Next you need to setup price categories and / or price tags for your templates in the designer. And you need to handle the data and call the uiHelper.refreshPriceDisplay within the priceChangeCallback to update the final price displayed beside the basket button.
