The link() function by default produces the title of the current page wrapped in HTML hyperlink tags.¹⁾ For example, in an out-of-the-box Wolf install, for the “About Us” page, this code:

<?php echo $this->link(); ?>

produces:

<a href="http://www.mywolfsite.com/about_us">About us</a>

link() can take two arguments: the first to give the title for the link (so overriding the default page title), the second can be used for other link parameters.

Assuming that “About Us” is still the “current” page, then this code:

<?php echo $this->link('Click here!'); ?>

will produce this link:

<a href="http://www.mywolfsite.com/about_us">Click here!</a>

To retain the default title, but add a further parameter, this code:

<?php echo $this->link($this->title, ' class="info"'); ?>

will produce this link:

<a href="http://www.mywolfsite.com/about_us" class="info">About us</a>
