codeigniter4-date-validation
============================

[](#codeigniter4-date-validation)

Custom validation library for the CodeIgniter4 framework to validate and compare dates.

To Do
-----

[](#to-do)

- Add rules:
- Use CodeIgniter4 coding standard library
- Create unit tests
- Use languae files for errors

Installation
------------

[](#installation)

### Installation via composer:

[](#installation-via-composer)

`composer require christianberkman/codeigniter4-date-validation`

If auto discovery in your CodeIgniter app is enabled, the library will be discovered automatically.

### Manual installation

[](#manual-installation)

Copy `src/DateValidation.php` to `app/ThirdParty`, adjust namespace and register in `app/Config/Validation.php`

Usage
-----

[](#usage)

The library offers rules for validating the value date to today or another field. All rules also validate the date so the built-in `valid_date` rule does not need to be called.

```
// any date before today's date
date_before_today[Y-m-d]

// any on or after a given field date
date_starting[date_arrival,Y-m-d]

// any date on Monday (1) or Wednesday (3)
date_on_dow[Y-m-d,1,3]

```

### Date Format

[](#date-format)

When comparing the value date to a field date, both dates are assumed to be in the same format. All format parameters are optional. If the format paremeter is specified, the dates will be creaed using `DateTime::createFromFormat`. If the format paremeter is omitted, the date is created using `strtotime()`. It is reccommended to always specify a format.

**Exception:** The format parameter is required for the `date_on_dow` rule, `'none'` can be specified if you wish to not specify any format: `'today' -> date_on_dow[none,1]`

### Time information

[](#time-information)

All time information is discarded, all times will be set to `00:00:00 UTC`.

Errors
------

[](#errors)

Errors are dynamically returned by each rule, e.g. `Date must be before last_available_date field`.

Available Rules
---------------

[](#full-example)

```
$data = [
    'arrival_date' => '2024-07-01',
    'excursion_date' => '2024-07-03',
    'depatrue_date' => '2024-07-10',
    'last_available_date' => '2027-08-09',
];

$rules = [
    // arrival needs to be at earliest tomorrow
    'arrival_date' => 'date_after_today',
    // excursion needs to be between (and not on) departure and arrival
    'excursion_date' => 'date_after[arrival_date,Y-m-d]|date_before[depatrue_date,Y-m-d]',
    // departure needs to be after (and not on) the arrival date and before (and not on) the last available date
    'departure_date' => 'date_after[arrival_date,Y-m-d]|date_before[last_available_Date]',
];

$validation = $this->validateData($data, $rules); // returns false
$errors = $this->validator->getErrors();
/**
