Jarvis

A simple but powerful way to validate data in PHP.

Requires php >= 7.0

Why ?

I needed to be able to make complex validation logic easily and to get a nicely formatted array with the validation errors associated with their keys. I couldn't find anything that satisfied these requirements so I made Jarvis.

Features

• Fluent interface
• Treats custom validation logic as first class citizen. They're just functions !!
• Get validation errors in a simple array, each error is associated to the input name. Only the first error for each field is kept.

Api

Validator

Example

Built-in rules

• between(min, max)
• isBoolean()
• isDate(format = 'Y-m-d')
• isJson()
• isNull()
• isNumber()
• isPositive()
• isUppercase()
• isString()
• lengthBetween(min, max)
• matchRegex(regex)
• notEmpty()
• noWhiteSpace()
• oneOf(...$functions)

Pro tips

There is two way to apply muliple validation rules for a single key :

• Use an array of validation functions -> this way you can only use a single error message
• Call addRule multiple times with the same key -> this way you can be more precise with your error messages

All function are curried so you can built-in rules without any argument rather than '\Jarvis\rules\isNumber'.

Todo

• Accept objects
• Add more default rules
