CARBONE.IO Conditional display (ifEQ) - if-statement

Question

I'm using Carbone to generate PDF with variables.
I need to make a conditional display. If a product have a specific category I need to display an information.
I tried to make the condition with ifEQ, show and showBeggin // showEnd but it does'nt work.
// My JSON
const json = {
shopping : {
sales :[
{
product_name: "Apple",
product_price: 2,
product_category: "fruits",
comment: "",
},
{
product_name: "Coke",
product_price: 3,
product_category: "soda",
comment: "",
},
{
product_name: "Cucumber",
product_price: 1.5,
product_category: "vegetable",
comment: "",
},
{
product_name: "Vodka",
product_price: 15,
product_category: "Alcohol",
comment: "Dangerous for health, prohibited at least 18 years old",
},
]
}
}
What I made on my document :
State
{d.shopping.sales[i].product_name} {d.shopping.sales[i].product_category(“Alcohol”):showBeggin} Information {d.shopping.sales[i].comment}, {d.shopping.sales[i].product_price}, {d.shopping.sales[i].produt_name}{d.shopping.sales[i].product_category::showEnd}
{d.shopping.sales[i+1].product_name}
Thank's for help !

Answer 1

Your example got a couple of errors, some fixes to do:
it is missing the ifEQ just before the showBegin
if the ifEQ argument is a string, it must be wrap with single quotes
showBeggin should be written showBegin
the last showEnd should be preceded by only one colon.
Here is your template with all corrections:
State
{d.shopping.sales[i].product_name} {d.shopping.sales[i].product_category:ifEQ('Alcohol'):showBegin}
Information {d.shopping.sales[i].comment}, {d.shopping.sales[i].product_price}, {d.shopping.sales[i].produt_name}{d.shopping.sales[i].product_category:showEnd}
{d.shopping.sales[i+1].product_name}
The conditional block documentation has been improved a lot, to get more examples: https://carbone.io/documentation.html#conditioned-output
Have a great day!
