Variables ¶
var ( ErrFileSizeLt = errors.New("file size is less than") ErrFileSizeGt = errors.New("file size is greater than") ErrInvalidFileContentType = errors.New("invalid file content type") )
Predefined errors
var DefaultFormMaxMemory int64 = 32 << 20 // 32 MB
DefaultFormMaxMemory is the default maximum amount of memory to use when parsing a multipart form.
var ErrValidation = errors.New("validation_failed")
ErrValidation is returned when validation fails.

func ValidateFileContentType ¶
func ValidateFileContentType(contentTypes ...string) fileValidationFunc
ValidateFileContentType validates file content type. It returns url.Values if there is an error otherwise it returns nil.
func ValidateFileFromRequest ¶
func ValidateFileFromRequest(r *http.Request, field string, validators ...fileValidationFunc) url.Values
ValidateFileFromRequest validates file size and content type from multipart form request. It returns url.Values if there is an error otherwise it returns nil.
func ValidateFileSize ¶
func ValidateFileSize(min, max string) fileValidationFunc
ValidateFileSize validates file size.
func ValidateImage ¶
func ValidateImage(file *multipart.FileHeader, field, min, max string) url.Values
ValidateImage validates image file size and content type. It returns url.Values if there is an error otherwise it returns nil.
func ValidateSolanaWalletAddr ¶

LocalPart string
// Domain is the part of the email address after the last @.
// This should be DNS resolvable to an email server.

func (EmailAddress) String ¶
func (e EmailAddress) String() string
func (EmailAddress) ValidateHost ¶

Err error // The underlying error.
Values url.Values // A map of field names to error messages.
}
ValidationError is a custom error type that contains a map of field names to error messages.
func NewValidationError ¶
func NewValidationError(values url.Values) *ValidationError
NewValidationError returns a new ValidationError.
func (*ValidationError) AddValue ¶
func (e *ValidationError) AddValue(key, message string) *ValidationError
AddValue adds a new error message to the map.
func (*ValidationError) AddValues ¶
func (e *ValidationError) AddValues(values url.Values) *ValidationError
