Can anyone tell me what the meaning of this error is and also guided me for the solution?

The CHtml button() method is literally just a button, the second parameter it accepts should be an array of key/value pairs, rather than an array of arrays (like you have in your example) see CHtml::button() for more info. A way to use this method would be for example;

echo CHtml::button('myButton',array(
    'class' => 'buttonClass',
    'id'    => 'buttonId',
));

This would output something like:

<input class="buttonClass" id="buttonId" name="yt1" type="button" value="myButton">

If you want a button to submit a form, you can use CHtml::submitButton() which will submit the form it is contained within.

If you want a button to actually redirect the user to a separate page without submitting anything then I think the best solution would be use an image with an anchor link, or use jQuery to redirect the user once the button has been pressed.

If that's the case, here's a question with a couple of answers that might help you out: How to make a button redirect to another page using jQuery or just Javascript
