README

ColorField is a form field for entering color in HEX, HEXA, RGB or RGBA format.

Installation

Just use the Composer:

cd path/to/your/atk14/project/
composer require atk14/color-field

ln -s ../../vendor/atk14/color-field/src/app/fields/color_field.php app/fields/color_field.php

Integration with Pickr

By default, ColorField renders <input type="text"> in which values like #FFFFFF, rgb(22,33,44), rgba(100,150,170,0.8) can be written. Nothing interesting... But ColorField is meant to be integrated with a nice color picker called Pickr (see https://github.com/Simonwep/pickr).

Pickr can be installed using npm:

npm install --save npm install @simonwep/pickr

And a small js utility needs to be linked into the project:

ln -s ../../../vendor/atk14/color-field/src/public/scripts/utils/color_picker_initializer.js public/scripts/utils/color_picker_initializer.js

Now edit gulpfile-admin.js (or gulpfile.js):

var vendorStyles = [
  // ...

  // ColorPickr: Include one of the following themes
  "node_modules/@simonwep/pickr/dist/themes/classic.min.css"
  //"node_modules/@simonwep/pickr/dist/themes/monolith.min.css"
  //"node_modules/@simonwep/pickr/dist/themes/nano.min.css"
];

// ...

var vendorScripts = [
  // ...
  
  // ColorPickr: modern or es5 bundle (in here, the modern bundle fails)
  //"node_modules/@simonwep/pickr/dist/pickr.min.js"
  "node_modules/@simonwep/pickr/dist/pickr.es5.min.js"
];

// ...

var applicationScripts = [
  // ...

  "public/scripts/utils/color_picker_initializer.js",

  // ...
];

Finally place the following line into function common.init() in public/admin/scripts/application.js (or public/scripts/application.js).

UTILS.color_picker_initializer.init();

Usage in an ATK14 application

In a form:

<?php
// file: app/forms/pages/create_new_form.php
class CreateNewForm extends AdminForm {

  function set_up(){
    // ...
    $this->add_field("background_color", new ColorField([
      "label" => "Background color",
      "initial" => "#4455ff",
      "opacity" => false,
      "theme" => "classic", // "classic", "monolith" or "nano"
      "swatches" => ["#4455ff", "#3366ee", "#223388","rgb(122,233,77)"]
    ]));
  }
}

Swatches

If the configuration file config/theme/colors.json or config/theme/colors.yml exists, ColorField will use the colors from this file as default swatches. The contents of the file might look like this:

{
  "primary": "#e75a76",
  "secondary": "#6c757d",
  "success": "#32a555",
  "info": "#17a2b8",
  "warning": "#ccb11b",
  "danger": "#e70000",
  "light": "#f5f5f5",
  "dark": "#343a40",
  "brand": "#307fa5"
}
