I encountered a tricky challenge when developing a project that requires color selection using the Yii 2.0 framework: how to efficiently implement a color selector in a form. I tried multiple methods, but the results were not ideal until I found the library sjaakp/yii2-iro, which completely solved my problem.

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>

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 istrue
. - 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.
