# Laravel 7 & 8 Full Calendar 5 Helper

This is a simple helper package to make generating [http://fullcalendar.io](http://fullcalendar.io) in Laravel apps easier.

Thanks to [@maddhatter](https://github.com/maddhatter) for the [initial repo](https://github.com/maddhatter/laravel-fullcalendar) for laravel < 7

## Installing
Require the package with composer using the following command:

    composer require acaronlex/laravel-calendar

The provider and `Calendar` alias will be registered automatically.

You will also need to include [fullcalendar.io](http://fullcalendar.io/)'s files in your HTML.

## Usage

### Creating Events

#### Using `event()`:
The simpliest way to create an event is to pass the event information to `Calendar::event()`:


```php
$event = \Calendar::event(
    "Valentine's Day", //event title
    true, //full day event?
    '2015-02-14', //start time, must be a DateTime object or valid DateTime format (http://bit.ly/1z7QWbg)
    '2015-02-14', //end time, must be a DateTime object or valid DateTime format (http://bit.ly/1z7QWbg),
    1, //optional event ID
    [
        'url' => 'http://full-calendar.io'
    ]
);
```
#### Implementing `Event` Interface

Alternatively, you can use an existing class and have it implement `Acaronlex\LaravelCalendar\Event`. An example of an Eloquent model that implements the `Event` interface:

```php
class EventModel extends Eloquent implements \Acaronlex\LaravelCalendar\Event
{

    protected $dates = ['start', 'end'];

    /**
     * Get the event's id number
     *
     * @return int
     */
    public function getId() {
		return $this->id;
	}

    /**
     * Get the event's title
     *
     * @return string
     */
    public function getTitle()
    {
        return $this->title;
    }

    /**
     * Is it an all day event?
     *
     * @return bool
     */
    public function isAllDay()
    {
        return (bool)$this->all_day;
    }

    /**
     * Get the start time
     *
     * @return DateTime
     */
    public function getStart()
    {
        return $this->start;
    }

    /**
     * Get the end time
     *
     * @return DateTime
     */
    public function getEnd()
    {
        return $this->end;
    }
}
```

#### `IdentifiableEvent` Interface

If you wish for your existing class to have event IDs, implement `\Acaronlex\LaravelCalendar\IdentifiableEvent` instead. This interface extends `\Acaronlex\LaravelCalendar\Event` to add a `getId()` method:

```php
class EventModel extends Eloquent implements \Acaronlex\LaravelCalendar\IdentifiableEvent
{

    // Implement all Event methods ...

    /**
     * Get the event's ID
     *
     * @return int|string|null
     */
    public function getId();

}

```

### Additional Event Parameters

If you want to add [additional parameters](http://fullcalendar.io/docs/event_data/Event_Object) to your events, there are two options:

#### Using `Calendar::event()`

Pass an array of `'parameter' => 'value'` pairs as the 6th parameter to `Calendar::event()`:

```php
$event = \Calendar::event(
    "Valentine's Day", //event title
    true, //full day event?
    '2015-02-14', //start time, must be a DateTime object or valid DateTime format (http://bit.ly/1z7QWbg)
    '2015-02-14', //end time, must be a DateTime object or valid DateTime format (http://bit.ly/1z7QWbg),
    1, //optional event ID
    [
        'url' => 'http://full-calendar.io',
        //any other full-calendar supported parameters
    ]
);

```

#### Add an `getEventOptions` method to your event class

```php
<?php
class CalendarEvent extends \Illuminate\Database\Eloquent\Model implements \Acaronlex\LaravelCalendar\Event
{
    //...

    /**
     * Optional FullCalendar.io settings for this event
     *
     * @return array
     */
    public function getEventOptions()
    {
        return [
            'color' => $this->background_color,
			//etc
        ];
    }

    //...
}

```

### Create a Calendar
To create a calendar, in your route or controller, create your event(s), then pass them to `Calendar::addEvent()` or `Calendar::addEvents()` (to add an array of events). `addEvent()` and `addEvents()` can be used fluently (chained together). Their second parameter accepts an array of valid [FullCalendar Event Object parameters](http://fullcalendar.io/docs/event_data/Event_Object/).

#### Sample Controller code (Using Script Tags and Browser Globals)

```php
$events = [];

$events[] = \Calendar::event(
    'Event One', //event title
    false, //full day event?
    '2015-02-11T0800', //start time (you can also use Carbon instead of DateTime)
    '2015-02-12T0800', //end time (you can also use Carbon instead of DateTime)
	0 //optionally, you can specify an event ID
);

$events[] = \Calendar::event(
    "Valentine's Day", //event title
    true, //full day event?
    new \DateTime('2015-02-14'), //start time (you can also use Carbon instead of DateTime)
    new \DateTime('2015-02-14'), //end time (you can also use Carbon instead of DateTime)
	'stringEventId' //optionally, you can specify an event ID
);

$calendar = new Calendar();
$calendar->addEvents($events);
$calendar->setOptions([
    'locales' => 'allLocales',
    'locale' => 'fr',
    'firstDay' => 0,
    'displayEventTime' => true,
    'selectable' => true,
    'initialView' => 'timeGridWeek',
    'headerToolbar' => [
        'left' => 'prev,next today myCustomButton',
        'center' => 'title',
        'right' => 'dayGridMonth,timeGridWeek,timeGridDay'
    ],
    'customButtons' => [
        'myCustomButton' => [
            'text'=> 'custom!',
            'click' => 'function() {
                alert(\'clicked the custom button!\');
            }'
        ]
    ]
]);
$calendar->setId('1');
$calendar->setCallbacks([
    'select' => 'function(selectionInfo){}',
    'eventClick' => 'function(event){}'
]);

return view('hello', compact('calendar'));
```

#### Sample Controller code (Using ES6 build system)

```php
$events = [];

$events[] = \Calendar::event(
    'Event One', //event title
    false, //full day event?
    '2015-02-11T0800', //start time (you can also use Carbon instead of DateTime)
    '2015-02-12T0800', //end time (you can also use Carbon instead of DateTime)
    0 //optionally, you can specify an event ID
);

$events[] = \Calendar::event(
    "Valentine's Day", //event title
    true, //full day event?
    new \DateTime('2015-02-14'), //start time (you can also use Carbon instead of DateTime)
    new \DateTime('2015-02-14'), //end time (you can also use Carbon instead of DateTime)
    'stringEventId' //optionally, you can specify an event ID
);

$calendar = new Calendar();
$calendar->addEvents($events)
->setOptions([
    'plugins' => [ 'window.interaction', 'window.momentPlugin', 'window.dayGridPlugin', 'window.timeGridPlugin', 'window.listPlugin' ],
    'locales' => 'window.allLocales',
    'locale' => 'fr',
    'firstDay' => 0,
    'displayEventTime' => true,
    'selectable' => true,
    'initialView' => 'timeGridWeek',
    'headerToolbar' => [
        'left' => 'prev,next today myCustomButton',
        'center' => 'title',
        'right' => 'dayGridMonth,timeGridWeek,timeGridDay'
    ],
    'customButtons' => [
        'myCustomButton' => [
            'text'=> 'custom!',
            'click' => 'function() {
                alert(\'clicked the custom button!\');
            }'
        ]
    ]
]);
$calendar->setId('1');
$calendar->setEs6();
$calendar->setCallbacks([
    'select' => 'function(info) {
        alert(\'selected \' + info.startStr + \' to \' + info.endStr);
    }',
    'eventClick' => 'function(info) {
        alert(\'Event: \' + info.event.title);
        alert(\'Coordinates: \' + info.jsEvent.pageX + \',\' + info.jsEvent.pageY);
        alert(\'View: \' + info.view.type);
        
        // change the border color just for fun
        info.el.style.borderColor = \'red\';
    }',
    'dateClick' => 'function(info) {
        alert(\'clicked \' + info.dateStr);
    }'
]);

return view('hello', compact('calendar'));
```


#### Sample View (Using Script Tags and Browser Globals)

Then to display, add the following code to your View:

```html
<!doctype html>
<html lang="en">
<head>
    <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
    <script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.9.0/moment.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/fullcalendar@5.5.0/main.min.js"></script>
    <script src="https://cdn.jsdelivr.net/npm/fullcalendar@5.5.0/locales-all.min.js"></script>
	
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/fullcalendar@5.5.0/main.css"/>
    
    
    <style>
        /* ... */
    </style>
</head>
<body>
    {!! $calendar->calendar() !!}
    {!! $calendar->script() !!}
</body>
</html>
```

#### Sample View (Using ES6 build system)

In your `/resources/js/app.js` add any necessary plugins after installing them with NPM.

```php
// FullCalendar.io
import { Calendar } from '@fullcalendar/core';
window.Calendar = Calendar;

import interaction from '@fullcalendar/interaction';
window.interaction = interaction;

import dayGridPlugin from '@fullcalendar/daygrid';
window.dayGridPlugin = dayGridPlugin;

import timeGridPlugin from '@fullcalendar/timegrid';
window.timeGridPlugin = timeGridPlugin;

import listPlugin from '@fullcalendar/list';
window.listPlugin = listPlugin;

import momentPlugin from '@fullcalendar/moment';
window.momentPlugin = momentPlugin;

import allLocales from '@fullcalendar/core/locales-all';
window.allLocales = allLocales;
```

In your `resources/css/app.scss` add the necessary CSS.

```
// Fullcalendar
@import '~@fullcalendar/bootstrap/main.css';
@import '~@fullcalendar/daygrid/main.css';
@import '~@fullcalendar/timegrid/main.css';
@import '~@fullcalendar/list/main.css';
```


Then in your blade view file output the HTML:

```php
<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
<head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link href="{{ mix('/css/app.css') }}" rel="stylesheet">
    
    <script src="{{ mix('/js/app.js') }}"></script>
</head>
<body>
    {!! $calendar->calendar() !!}
    {!! $calendar->script() !!}
</body>
</html>
```

#### Notes

**Note:** The output from `calendar()` and `script()` must be non-escaped, so use `{!!` and `!!}` (or whatever you've configured your Blade compiler's raw tag directives as).

The `script()` can be placed anywhere after `calendar()`, and must be after fullcalendar was included.
