Template Funcs - Custom

Introduction

Developers can define custom template functions and globally bind them to specified view objects.

tip

Custom objects can also be assigned to templates, allowing method calls on those objects.

Example

package main

import (
    "context"
    "fmt"
    "github.com/gogf/gf/v2/frame/g"
)

// Test built-in function with parameters
func funcHello(name string) string {
    return fmt.Sprintf(`Hello %s`, name)
}

func main() {
    // Bind global template function
    g.View().BindFunc("hello", funcHello)

    // Pass parameters in a regular way
    parsed1, err := g.View().ParseContent(context.TODO(), ``hello "GoFrame"``, nil)
    if err != nil {
        panic(err)
    }
    fmt.Println(string(parsed1))

    // Pass parameters through a pipeline
    parsed2, err := g.View().ParseContent(context.TODO(), ``"GoFrame" | hello``, nil)
    if err != nil {
        panic(err)
    }
    fmt.Println(string(parsed2))
}

After execution, the output is:

Hello GoFrame
Hello GoFrame
