DateRangePickerHelper

By Sébastien L'haire

DateRangePickerHelper is a Laravel library to provide an helper to initialize a single or double DateRangePicker calendar (based on jQuery Javascript framework). Dates use Nesbot Carbon on PHP side and Moment.js on Javascript side. Demo site available here.

Single date picker appears as follow:

And range date picker appears as follow:

Installation

1. composer require seblhaire/daterangepickerhelper

2. You can either download DateRangePicker on its website or install it with npmpackage manager if you compile your app Javascript files with Laravel Mix. Same choice for Bootstrap, jQuery and Moment. npm install jquery daterangepicker moment bootstrap.

3. Composer will automatically link the package with Laravel. But you still can explicitely add provider and facade to your config/app.php:

4. Publish package (optionally).

5. Add style to your app.scss file:

6. add to app.js

Usage

Declare Facade in Controller headers:

In a Controller function initialize object and pass it to the view. You can init several DateRangePickers in a view, but make sure that calendar id is unique.

Then in the Blade view, print your calendar like this:

{!! $calendar->output() !!} or {!! $calendar !!}

If $calendarElement is set to "mycal", the following line is printed, with options between rounded brackets:

Alternatively, you can init it in controller without variable assignation and use facade in view:

Controller:

View:

If your view contains only one DaterangePicker, you can omit calendar id:

Config File

Config file daterangepickerhelper.php is available, either in package directory in vendor/seblhaire/daterangepickerhelper or in your app config directory if you publish config. Parameters not language-dependent are in default section. Language-dependant parameters are in language section.

Parameters

• $calendarElement: mandatory id of <div> element containing current date(s) selected in calendar, where you can click to open date selector.
• $start, $end: mandatory \Carbon\Carbon objects: initial period selected on calendar opening. Both dates can be the same.
• $min, $max: \Carbon\Carbon objects: boundary dates. Null if no boundary. Users will not be able to select a date before $min or after $max.

• $options: array of options among:

  • main used:
  • singleDatePicker: calendar selects one date instead of date range. Default: false.
  • showISOWeekNumbers or showWeekNumbers: adds week numbers in calendar. If first option is set to true, weeks will be in ISO format. If second option is true, weeks will be shown in US format. If none of them is true, then week numbers will not be shown. Default settings depend on locale.
  • timePicker: add dropdowns to select time in addition to dates. Default false.
    • timePicker24Hour: displays hours in format 24. Default true.
    • timePickerSeconds: add seconds to time. Default false.
    • timePickerIncrement: minutes increment in dropdown. Default 1.
  • weeklabel: Very short label for week number column. Abreviation is recommended. Default translation key calendar::messages.weeklabel W.
  • firstday: first day of week. 0 = sunday, 1 = monday, etc. Default depends on locale.
  • usehiddeninputs: sets whether we put selected date(s) (and time) in hidden input/s. Default: true.
    • single calendar: default input name is the same value as $calendarElement. If you want another input name, set hiddensingleinput value. Input id is the value of $calendarElement followed by '-hidden-date'.
    • double calendar:
      • start date: default input name is value of $calendarElement followed by '-start'. If you want to change this value, set hiddeninputstart value. Input id is value of $calendarElement followed by '-hidden-startdate'.
      • end date: default input name is value of $calendarElement followed by '-end'. If you want to change this value, set hiddeninputend value. Input id is value of $calendarElement followed by '-hidden-enddate'.
  • date format: Carbon formats are used to initialize calendars. Moment.js formats are used on new date selection. We need both formats. In order to facilitate configuration, we define several versions depending on preceding parameters, in order to format a correct date, with or without time, with or without seconds:
  • momentinput: Momentjs format to fill hidden inputs (see usehiddeninputs). Choices are 'momentinputdate' or 'momentinputdatetime'.
  • carboninput: Carbon format to fill hidden inputs (see usehiddeninputs). Choices are 'carboninputdate' or 'carboninputdatetime'.
  • carbonformat: Carbon format to initialize dates next to calendar icon. Choices are 'carbonformat', 'carbonformattime' or 'carbonformattimeseconds'.
  • formatdisplay: Momentjs format to display dates. Choices are 'formatdisplay', 'formatdisplaytime' or 'formatdisplaytimeseconds'.
  • other options:
  • caldivclass: calendar div class. Default "form-group cal-selector".
  • icon: calendar icon (default: FontAwesome '<i class="fas fa-calendar-alt"></i>).
  • opens: ('left'/'right'/'center') direction where calendars opens in respect to the <div> it is attached to. Default right.
  • drops: ('down'/'up'/'auto') vertical direction where calendars open. Default: auto.
  • maxSpan: moment function which sets the max span between start and end date (eg: "day": 7). Default: no value.
  • minYear, maxYear: minimum and maximum years to display in dropdowns.
  • fillhiddeninputsfunction: Javascript statements to be put in Datepicker callback function which is run after a new date range (or a new date for single Datepicker) is set by Apply button. This callback function has 3 arguments function(start, end, label). start and end are Moment objects. label is a string which contains the date range label used, cf range below. Defaults:
    • if you fill this option, your statements will be executed.
    • if this option is empty and usehiddeninputs option is true, hidden date inputs are filled with a date (+ time if applicable) in Mysql format (Y-m-d, Year-month-date, 2019-12-24 is December 24th 2019) and date or date range in human readable format next to calendar icon is replaced.
    • otherwise callback function is empty.
  • dateseparator: string used to separate dates of a range. Default ' - '.
  • daysofweek: array of short labels, starting from sunday: ['Su', 'Mo', ... 'Sa']. You can either provide your own array or modify/add translation keys, calendar::messages.day0 to calendar::messages.day6. Cf below.
  • monthnames: array of month names ['January' ... 'December']. You can either provide your own array or modify/add translation keys, calendar::messages.month01 to calendar::messages..month12. Cf below.
  • ranges: array of ranges to set double calendar. First value is a label. Second value is an array with two momentjs functions to set values. Labels can be strings or translation key. Cf below.
  • applylabel: button label to select date/range. Default_translation key calendar::messages.applylabel: 'Select' Cf below.
  • cancellabel: cancel button label, default_translation key calendar::messages.cancellabel 'Cancel'. Cf below.
  • fromlabel: Label before range begin date. Default translation key calendar::messages.fromlabel 'From'. Cf below.
  • tolabel: Label before range end date. Default translation key calendar::messages.tolabel 'To'. Cf below.
  • customrange: Label for custom range select. Default translation key calendar::messages.customrange 'Custom range'. Cf below.
  • inform: calendar can be inserted in a form. If true, calendar is included in a <div> and preceded by a label (cf option formlabel). Default true.
  • formdivclass: if inform is set, this option sets class of <div>.
  • formlabel: if inform is set, this option sets class of <label>.
  • alwaysShowCalendars: when ranges are set (cf above), calendars are hidden by default unless you select "Custom ranges". If you set alwaysShowCalendars to true, calendars will be always visible. Default: true.
  • showDropdowns: Put month and years in dropwdowns. Default false.
  • autoApply: Hide Apply and Cancel buttons and set dates as soon as two dates are selected. Default false.
  • linkedCalendars: both calendars always are in contiguous month if set true. Default: false.

  • hideCalendar.daterangepicker: content of listener for event "hideCalendar.daterangepicker" triggered when the calendar(s) are hidden. Default empty. Cf apply.daterangepicker.

Translation keys

Laravel loads config files very early in process. Therefore config files cannot contain __('translation.key'). In order to solve this issue, we made an helper either to print directly strings or to send translation key to translation helper. Translation keys can be delimited by character # Ex: "#formsbootstrap::messages.required#".

Feel free to translate keys in your own language and either to send it to the author or to do a merge request on GitHub.

Helpers

So far you have just initialized DateRangePickerHelper. But in your JS code, you need to retrieve new dates or date ranges set by your app user and/or to change dates dynamically, e.g. after you retrieve object from databases. DateRangePicker comes with methods to get and set new dates, but it is not easy to use, as shown here:

You have to remember the id of <div> tag that the DateRangePicker is attached to and to format dates with Moment syntax. However in most cases, you use DateRangePickerHelper with standard date format which has been already set in default options. Therefore we have set getters and setters.

Getters

By default, your DateRangePicker will be inserted in a form. Therefore, you can retrieve all form values e.g. with jQuery('form').serialize(). Alternatively, date can be retrieved by e.g. jQuery('#startdate').val(). If calendar is not in a form, date value can be retrieved by the complex statement above. No need to figure out how your calendar is set, DateRangePickerHelper comes with two getters:

• getStartDate()
• getEndDate()

These methods output the adequate JS statement to get a date according to your DateRangePickerHelper settings. In the following example, in your blade template, if your DateRangePickerHelper is passed to variable $calendar, you may retrieve dates this way:

You can also use facade to access these methods:

That's it.

Setters

On the other side, your Ajax queries may load information in forms and other objects. Both DateRangePicker and label next to calendar icon must be changed. We provide several methods for that purpose.

• setSingleCalendar($momentdate) : sets both single calendar and label. $momentdate must be a Moment statement, eg. moment(data.date), where data.date is a date in MySql format (2020-09-10 or 2020-09-10 14:10:09) ;
• setDoubleCalendar($momentstartdate, $momentenddate) : sets both double calendar and label, both parameters are Moment statements ;
• setStartDate($momentdate) : sets single calendar date or start date for double calendar ; parameter is a Moment statement ;
• setEndDate($momentdate) : sets end date for double calendar ; parameter is a Moment statement ;
• setCalLabelSingle($momentdate) : outputs date for label for single calendar ; parameter is a Moment statement ;
• setCalLabelDouble($momentstartdate, $momentenddate) : outputs date rang; parameters are Moment statements .

Method reset() resets the calendar with the initial values.

In the following example, in your blade template, if your DateRangePickerHelper is passed to variable $calendar, you may set dates this way:

With the Facade, use the followig methods. $calId parameter can be ommited if view has only one DateRangePicker.

• DateRangePickerHelper::setSingleCalendar($momentdate, $calId)
• DateRangePickerHelper::setDoubleCalendar($momentstartdate, $momentenddate, $calId)
• DateRangePickerHelper::setStartDate($momentdate, $calId)
• DateRangePickerHelper::setEndDate($momentdate, $calId)
• DateRangePickerHelper::setCalLabelSingle($momentdate, $calId)
• DateRangePickerHelper::setCalLabelDouble($momentstartdate, $momentenddate, $calId)
