HeadLink()->headLink(array('rel' => 'favicon', 'href ' => $this->baseUrl(). '/css/', 'print') ?>įavicons are attached in a similar way, only we use the generic headLink() member function, rather than the CSS-specific functions: HeadLink()->appendStylesheet($this->baseUrl(). We can also set the media for the stylesheet by setting the second parameter, so for a print stylesheet, the following code is used: There is also a prependStylesheet () member function for controlling the order of output, and for alternative stylesheets appendAlternate() and prependAlternate() can be used.

It aggregates the elements together while rendering each view script and is later used to render the elements into the layout. This includes CSS stylesheets, favicons, RSS feeds, and trackbacks. HeadLink() manages elements in the section of the document. You still need to echo it at the top of your (X)HTML output, but you don't need to pass in the value again. For that reason, it's best to set the doc type early in the dispatch process, such as in dispatchLoopStartup() of your ViewSetup front controller plug-in. TIP Some view helpers, especially the form-related ones, will output either HTML- or XHTML-compliant code, depending on the value passed into the doctype() view helper. You can also test for XHTML or not in other view scripts using the isXhtml () member function. The doctype() view helper understands all XHTML 1 and HTML 4 doctype declarations, and this also affects the rendering of the relevant head*() view helpers so that they are compliant with the doctype specified. As with all view helpers, you simply echo it out: It mainly solves the problem of having to look up the correct document type from the W3C website. The doctype() view helper is a convenience helper for creating the doc type in the HTML file. Let's start by looking at the doctype() view helper, as this one is used at the very top of the page. This component will use the json PHP extension if it is available otherwise it will fall back to a native PHP implementation.Īll the other HTML head view helpers output text into the HTML page.

Given an array or object called data, it is encoded and sent to the browser using this code: ■ Sets the HTTP header content-type to application/j son. The json () view helper is used when sending JSON data to the web browser, usually in response to an Ajax request. There are a variety of helpers that mostly begin with the word head, and two, json() and doctype (), which are also used at the head of a document.
