Valid8r for PHP

Valid8r is a validation library for multiple programming languages using a common JSON configuration file. Learn more about Valid8r and the configuration file at:

https://github.com/thomporter/valid8r

Installation

Valid8r for PHP really only has one file you need. If you don't care about testing, examples, etc, you can simply grab the Valid8r.php file from the lib/Valid8r folder:

https://raw.github.com/thomporter/valid8r_php/master/lib/Valid8r/Valid8r.php

Alternatively, you can clone this rep and get examples & tests.

You can also install via Composer:

{
  "require": {
    "valid8r/valid8r_php": ">=v0.0.3"
  }
}

Examples

Get the Examples folder running on an PHP enabled web server and you can check out the Kitchen Sink examples.

Here's a quick idea of how it works in PHP:

<?php
$validator = new Valid8r(Array(
	'rules_file' => '/path/to/your/rules.json',
	'data' => $_POST // assumed to be slash-free
));
$errors = $validator->validateAll();
// errors is now an associative array, where the keys are fields with 
// errors, and values are the errors themselves.  
// Fields with no errors are not in the array.

if (!empty($errors)) {
	// there was at least one error in the form...
}

if (@$errors['field_name']) {
	// field_name has an error, the error string is in $errors['field_name']
}

Custom Validators

For general information about Custom Validators, see the main Valid8r docs

Valid8r for PHP supports custom validators via any of the following:

• Standard Functions
• Static Methods of Classes
• Instance Methods of Classes

No matter which you use, your function must accept 2 arguments ($field & $value) and must either return a string to use as the error, or a blank string if no error.

Custom Validators using Standard Functions

Just use the function name as the value for the func property of your custom rule and Valid8r will access it directly.

Custom Validators using Static Methods

You can add a php_static_class to your custom rule and Valid8r will combine that with the func property to build the call:

$php_static_class::$func($field, $value)

You can also add a php_namespace which will cause Valid8r to make the call like so:

$php_namespace\$php_static_class::$func($field, $value)

Custom Validators using Instance Methods

If you need Valid8r to initialize a class, and then call a method on it, this is the options for you. Add a php_class property, and Valid8r will make the call like so:

$validator = new $php_class
$validator->$func($field, $value)

Tests

PHPUnit tests are available if you clone/download the repo. Once you have PHPUnit installed, you can run the tests with:

`run-tests`
