Basic Usage

The Template Printing plugin provides various syntaxes to flexibly insert dynamic data and logical structures into templates. Below are detailed syntax explanations and usage examples.

Basic Replacement

Use placeholders in the format {d.xxx} for data replacement. For example:

{d.title}: Reads the title field from the dataset.
{d.date}: Reads the date field from the dataset.

Example:

Template Content:

Dear Customer,

Thank you for purchasing our product: {d.productName}.
Order ID: {d.orderId}
Order Date: {d.orderDate}

Wish you a pleasant experience!

Dataset:

json

{
  "productName": "Smart Watch",
  "orderId": "A123456789",
  "orderDate": "2025-01-01"
}

Rendered Result:

Dear Customer,

Thank you for purchasing our product: Smart Watch.
Order ID: A123456789
Order Date: 2025-01-01

Wish you a pleasant experience!

Accessing Sub-objects

If the dataset contains sub-objects, you can access the properties of the sub-objects using dot notation.

Syntax: {d.parent.child}

Example:

Dataset:

json

{
  "customer": {
    "name": "Alex Smith",
    "contact": {
      "email": "[email protected]",
      "phone": "+1-555-012-3456"
    }
  }
}

Template Content:

Customer Name: {d.customer.name}
Email Address: {d.customer.contact.email}
Phone Number: {d.customer.contact.phone}

Rendered Result:

Customer Name: Alex Smith
Email Address: [email protected]
Phone Number: +1-555-012-3456

Accessing Arrays

If the dataset contains arrays, you can use the reserved keyword i to access elements in the array.

Syntax: {d.arrayName[i].field}

Example:

Dataset:

json

{
  "staffs": [
    { "firstname": "James", "lastname": "Anderson" },
    { "firstname": "Emily", "lastname": "Roberts" },
    { "firstname": "Michael", "lastname": "Johnson" }
  ]
}

Template Content:

The first employee's last name is {d.staffs[i=0].lastname}, and the first name is {d.staffs[i=0].firstname}

Rendered Result:

The first employee's last name is Anderson, and the first name is James
