The Gravatar view helper is used to received avatars from Gravatar's service. gravatar('example@example.com'); /* results in the following output: */ ]]> Of course we can configure this helper. We can change height of image (by default it is 80px), and add CSS class or other attributes to image tag. The above simply shows the most basic usage. The email address you provide the helper should be valid. This class does not validate the address (only the rating parameter). It is recommended to validate your email address within your model layer. There are several ways to configure the returned gravatar. In most cases, you may either pass an array of options as a second argument to the helper, or call methods on the returned object in order to configure it. The img_size option can be used to specify an alternate height; alternately, call setImgSize(). The secure option can be used to force usage of SSL in the returned image URI by passing a boolean true value (or disabling SSL usage by passing false). Alternately, call the setSecure() method. (By default, the setting follows the same security as the current page request.) To add attributes to the image, pass an array of key/value pairs as the third argument to the helper, or call the setAttribs() method. gravatar('example@example.com', array('imgSize' => 90, 'defaultImg' => 'monsterid', 'secure' => true), array('class' => 'avatar', 'title' => 'Title for this image') ); // Or use mutator methods $this->gravatar() ->setEmail('example@example.com') ->setImgSize(90) ->setDefaultImg(Zend_View_Helper_Gravatar::DEFAULT_MONSTERID) ->setSecure(true) ->setAttribs(array('class' => 'avatar', 'title' => 'Title for this image')); /* Both generate the following output: */ ]]> img_size An integer describing the height of the avatar, in pixels; defaults to "80". default_img Image to return if the gravatar service is unable to match the email address provided. Defaults to "mm", the "mystery man" image. rating Audience rating to confine returned images to. Defaults to "g"; may be one of "g", "pg", "r", or "x", in order of least offensive to most offensive. secure Whether or not to load the image via an SSL connection. Defaults to the what is detected from the current request.
