Question

On docs we can read:

public static string link(string $text, mixed $url='#', array $htmlOptions=array ( ))

Question:
I don’t understand what $htmlOptions means here. I don’t understand how to pass from this representation to a real code.

Can anyone please provide an example about how can we generate a link with a class defined.
Something like:

<a href="#" class="hello">link hello</a>

Answer 1

It’s easier than you might think, although Yii’s documentation is perhaps a bit more convoluted than needs to be. However, it does say that $htmlOptions is

additional HTML attributes. Besides normal HTML attributes, a few
special attributes are also recognized (see clientChange and tag for
more details.)

In essence, whatever key/value pairs you put into the array will come out as HTML attributes¹. So, what you want to do is

CHtml::link('link hello', '#', array('class' => 'hello'));

¹except the “special” values that the docs refer to, which will not end up rendered in HTML as-is but either modify the way link works slightly, or end up affecting the HTML in other ways.
