Validation rules include requiring specific keys, specific types and specific values. When the validation fails, the library throws a normal *Exception*. For best results, also consider using our [Array Sanitization](https://github.com/multidimension-al/array-sanitization) library which will correct errors and force type corrections prior to validation. Requirements ------------ [](#requirements) - PHP 5.5+ Installation ============ [](#installation) The easiest way to install this library is to use composer. To install, simply include the following in your `composer.json` file: ``` "require": { "multidimensional/array-validation": "*" } ``` Or run the following command from a terminal or shell: ``` composer require --prefer-dist multidimensional/array-validation ``` You can also specify version constraints, with more information available [here](https://getcomposer.org/doc/articles/versions.md). Usage ===== [](#usage) This library utilizes PSR-4 autoloading, so make sure you include the library near the top of your class file: ``` use Multidimensional\ArrayValidation\Validation; ``` How to use in your code: **Create Ruleset** ``` $rules = ['keyName' => ['type' => 'string', 'required' => true]]; ``` **Check an array against that ruleset** ``` $array = ['keyName' => 'text']; $bool = Validation::validate($array, $rules); echo $bool; //true ``` The validation process will return true or false and will throw an exception. Advanced Rulesets ================= [](#advanced-rulesets) Many examples of rules can be found in the `ValidationTest.php` file. ### Types [](#types) There are several different valid types for the values in the array they are as follows: - String - Integer - Decimal - Boolean - Group (Multidimensional array) ### Pattern Matching [](#pattern-matching) You can specify basic regular expressions that can be used to access whether a value is valid or not. Examples of pattern matching: - \[A-Z\]{2} *(match two capital letters)* - \\d{5} *(matches 5 digits)* - \\d{5}-\\d{4} *(matches ZIP+4)* Built in patterns available for matching: - URL - Email - IP Address (IPv4 or IPv6) - MAC Address (Dashes, Colons or Dots) - [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) ### Required Values [](#required-values) It is possible to set a key as being required or not, but it is also possible to adjust requirements based on the the values of the other keys. For example, a key could be required if the value of another key is equal to *null* or if another key has a specific value. Here is an example from our *ValidationTest.php* file: ``` $rules = [ 'a' => ['type' => 'string', 'required' => true], 'b' => ['type' => 'string', 'required' => [ 'a' => 'banana' ] ], 'c' => ['type' => 'string', 'required' => [ [ 'a' => 'banana', 'b' => 'orange' ], [ 'a' => 'banana', 'b' => 'carrot' ], [ 'a' => 'pickle' ], [ 'b' => 'banana' ] ] ] ]; ``` Under this example the following are true: - Key 'a' is always required. - Key 'b' is required when key 'a' is "banana". - Key 'c' is required when ONE of the following is true: - Key 'a' is "banana" and key 'b' is "orange" - Key 'a' is "banana" and key 'b' is "carrot" - Key 'a' is "pickle" - Key 'b' is "banana" Here you can see the required functionality can be made to be quite complex. ### Specified Values [](#specified-values) In some instances where you would only have a small subset of specific values that would be considered valid, you can specify those values in the ruleset by providing am array of valid values. ``` $rules = ['a' => ['type' => 'string', 'values' => ['cat', 'dog']]]; ``` In the above example, key 'a' must be either "cat" or "dog". Note that this string comparison is case-insensitive!
