# govalid

A simple Go struct validator.

[![Go Report Card](https://goreportcard.com/badge/github.com/wuhan005/govalid)](https://goreportcard.com/report/github.com/wuhan005/govalid)

## Quick Start

```bash

go get -u github.com/wuhan005/govalid

```

```go

v := struct {

    Name string `valid:"required;username" label:"昵称"`

    ID   int    `valid:"required;min:0;max:999" label:"用户编号"`

    Mail string `valid:"required;email" label:""`

}{

    "e99_", 1990, "[email protected].",

}

errs, ok := govalid.Check(v)

if !ok {

    for _, err := range errs {

        fmt.Println(err)

    }

}

```

Output:

```text

昵称的最后一个字符不能为下划线

用户编号应小于999

不是合法的电子邮箱格式

```

## Customize Error Message

```go

govalid.SetMessageTemplates(map[string]string{

    "required": "can't be null.",

    "min": "must bigger than %v.",

})

```

## Customize Error Check Function

```go

func main() {

	// set your error message.

	govalid.SetMessageTemplates(map[string]string{

		"mycheck": "content cann't contain 'e99'.",

	})

	// add new check function

	govalid.Checkers["mycheck"] = func(c govalid.CheckerContext) *govalid.ErrContext {

		errCtx := govalid.NewErrorContext(c)

		value, ok := ctx.Value.(string)

		if !ok {

			return MakeCheckerParamError(c)

		}

		if strings.Contains(value, "e99") {

			return ctx

		}

		// if the check passed, return nil.

		return nil

	}

	r := struct {

		Content string `valid:"mycheck"`

	}{

		"helloe99",

	}

    errs, ok := govalid.Check(v)

    if !ok {

        for _, err := range errs {

            fmt.Println(err)

        }

    }

}

```
