sjaakp/yii2-iro is a color selector widget designed for Yii 2.0 framework. It is based on iro.js , an excellent JavaScript color selection library, developed by James Daniel. With this widget, you can easily add a color selection function to the form, supporting two modes: display directly on the page (inline) or pop up the dialog box (popup) by clicking the colored button.

Install sjaakp/yii2-iro

Installing this library is very simple, just use Composer. You can add the following code in the require section of the composer.json file:

 <code class="json">"sjaakp/yii2-iro": "*"</code>

Or run the following command directly:

 <code class="bash">composer require sjaakp/yii2-iro</code>

If you prefer manual installation, you can also download the source code in ZIP format.

Using sjaakp/yii2-iro

Using sjaakp/yii2-iro in ActiveForm for Yii 2.0 is very simple, just like using any other InputWidget . For example, in an ActiveForm , you can use this:

 <code class="php"><?php use sjaakp\iro\IroWidget;
?>...<?php $form = ActiveForm::begin([
    // ...options...
]); ?>= $form-> field($model, 'name') ?>= $form-> field($model, 'favourite_color')->widget(IroWidget::class, [ /* ...options... */ ]) ?> ?> ...<?php $form = ActiveForm::end(); ?> ...</code>

If you want to use sjaakp/yii2-iro outside of ActiveForm , you can do this:

 <code class="php"><?php use sjaakp\iro\IroWidget;
?>...= IroWidget::widget([
    'name' => 'iro', 'value' => '#00ff00', 'popup' => false // ... ]) ?>; ...</code>

Configuration Options

sjaakp/yii2-iro provides a variety of configuration options, including:

  • clientOptions : Options for configuring the underlying iro.js color selector, default to an empty array.
  • popup : determines how the widget is displayed. false means that it is displayed directly on the page. true means that the dialog box pops up by clicking the color button, and the default is true .
  • opacity : Decide whether to provide an alpha slider.
  • colorFormat : Specify the color format, default is 'hexString' .

Practical application effect

In my project, using sjaakp/yii2-iro greatly improves the user experience. The user can intuitively select the color, and the flexibility of the two display modes allows widgets to adapt to different interface needs. In addition, the powerful features of iro.js and the ease of use of sjaakp/yii2-iro make the development process more efficient.

Overall, sjaakp/yii2-iro is a powerful tool that not only solves the color selection issues I encountered in my project, but also provides a wealth of configuration options that make customization very simple. If you need a color selector when developing your project with Yii 2.0 framework, it is highly recommended to try sjaakp/yii2-iro .
