#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:

{
  "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:

{
  "customer": {
    "name": "Alex Smith",
    "contact": {
      "email": "alex.smith@example.com",
      "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: alex.smith@example.com
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:

{
  "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
