This means that you can use Yii for free to develop either open-source or proprietary Web applications. There are two ways to install Yii: by using Composer or by downloading an application template.
We highly recommend you to use Composer. If you do not have Composer installed yet, you may install it following the instructions on the Composer website. Latest release is 2. The viewpath, in turn, acts as the base to determine the relative path you mention as the first argument of the Controller. This viewpath is appended with the ID of the controller we call render on.
Yii 2 creates a controller ID in a very simple way. The name of the Controller class is stripped off the Controller suffix, and then the leftover name in the uppercase is replaced with the dash-separated one.
Previously, we mentioned that the default extension expected from the view file is php. However, fully relative paths are not all that you can use. If you start a path with the symbol, it'll be treated as the Yii path alias.
Path aliases were in Yii 1. Now, only the first token will be expanded. Yii 2 is so nice that it defines the five most important alias tokens for is the absolute path to the directory containing the index.
As a result, in the default application setup for example, in the basic application equals the document root set in the web server host setup, is empty. You can use aliases when specifying the path to the view file. Almost any setting of the base Yii components, which accepts some sort of path, accepts aliases as well. Apart from aliases, you can specify the absolute path for the view files. Absolute means not in terms of a filesystem, but in terms of the application code base.
In this case, Yii will start from viewpath of the current module. In case an application lacks any modules, it will work as the only module, so a single slash is equivalent to two slashes. In fact, in the case of a fully relative view file path, the path expands relative to the current module, and not just from the application's viewpath.
Algorithm to search the layout file to be used The Controller. The View. Layout is just another view file and it's processed as any other view file. It's the text string that contains the result of rendering the view file we really want to render. The controller has to find the Layout file in some way. In this way, it does not depend on the view file alias that we pass to the render method. In fact, Controller has the layout property that holds the path alias to the Layout file render has to use.
If for some reason you set the layout property to false, the layout system will be disabled and the controller will render just the view file requested. If the layout property is set to null, the value of the layout property of the parent module will be used.
As mentioned in Chapter 2, Making a Custom Application with Yii 2, the top-level module, which is a parent to all the other ones, is the application itself. By default, layoutpath contains the folder named layout inside the folder pointed by the viewpath property. By using path aliases with symbol, you can point to any folder in the application code base. By default, Controller. This means that Yii should use the layout property of the module containing that controller.
Even if you use the system of modules, by default, each module starts with the layout property equal to null anyway. This means that the application's global layout value will be used, which is usually set in the application config. The default value of this property is main, which is the main. If you specify the file extension, the php extension will not be appended automatically.
The internal workings of rendering the view file While we certainly don't want to go too deep into the internal workings of the View component, Yii forces us to do so by the conventions of structuring the layout files.
We will look at the custom renderers in the very next section. We have used the following methods of the View component there: Method beginpage head beginbody endbody endpage Explanation This starts buffering the content that follows it.
Everything after this call is buffered until the endpage call is expected to be postprocessed. This marks the location to place the dynamically-registered elements into.
It also puts an end to buffering. It actually inserts the registered meta, link, style, and script elements into the resulting HTML page. So if you're absolutely crazy, you can even start the second sequence of the HTML page rendering afterwards. Moreover, everything around the beginpage Custom renderers With all this, you now probably know the most contrived part of the Yii conventions.
Let's now talk about the custom renderers. Yii uses renderers to process the view file you referenced in the render method, based on its file extension. An important effect of custom renderers is that you can do anything inside your view files, which will be dangerous if you really do anything. You should ideally treat PHP view files as being in some template system's format, only allowing them to paste data passed to them as associative arrays or plain data structures. Let's think about how we can utilize this feature for our convenience.
The original design goal of the developers, obviously, was that you'll write the parser for some template system format, and then you'll be able to write view files not as raw PHP, but as these supposedly, more restricted, and domain-specific templates. By giving the templates a new format with a distinct extension, you'll force Yii to use your custom parser on them, which will supposedly convert the given template to, say, HTML, which you'll send to the client.
Let's employ a simple solution here, which is using Markdown daringfireball. Let's say we want the set of user-level documentation pages, which will be handcrafted by a skilled tech writer. Markdown will be a simple middle ground for this task.
Employing a custom renderer to render static Markdown files is pretty simple. We assume that you have the same CRM application we have been building in the previous two chapters. First, let's declare what we want:. Don't forget to run. I see "Documentation","h1" 1. Create the SiteController. It's easier to write text documents with simple formatting this way. Imagine the user documentation here, describing: 1. Here is the screenshot: Finally, let's write the custom renderer itself. As this class is a part of the application infrastructure and has nothing to do with the domain model or the route handling, let's create a separate utilities subdirectory and namespace for it.
You may ask, how do we render the Markdown? The MarkdownRenderer class does not have the proper unit tests because arguably all we did was wrap two built-in and already extensively tested functions into one call. To simplify the discussion, we omitted the proper test-driving MarkdownRenderer. Note, however, that in more complex cases, you must not do this. It is not all the time that you have a parser as simple as the one presented here.
With MarkdownRenderer written, we have to wire it to the application. Add the description of our custom renderer to the components. In our case, it should be md. Our renderer does not have any properties, so to properly reference it in the application configuration, we just need to provide the fully qualified name of its class. Anything that the controller action returned is wrapped into the Response object, which decides how to ultimately send the data down the pipe.
Let's see how we can utilize a custom response formatter for our purposes. Probably the most obvious use of the custom response formatter is returning the JSON data for a given route. Note that the correct content-type HTTP header was set by the server. First, we have to note that we do not render anything here. The data we get, an associative array, is wrapped into a manually crafted Response instance and returned from the controller action and added to the Response.
When we return the string generated by the Controller. In fact, everything that is not Response descendant and is being returned from the controller action will be added to the Response. This way, we get the default values of its properties already set by Yii at the application initialization step.
The Response object is used exactly once in an application's lifetime, so there's really no difference whether we'll get it as a Yii component or by calling construct.
The format field tells the Response object how to format the outgoing data. No processing will be done on the data, except that objects will be serialized using the tostring call. Data will be returned without any processing, except that objects will be serialized using the tostring call. Content-Type will not be set by Yii. Data will be processed by the Json::encode method shipped with the Yii framework. Data must be an array with the callback string element and the data element.
The response is the string callback data , where data is processed by Json::encode. Data will be processed by the XmlResponseFormatter class. Data is expected to be either an associative array or an object with public fields. In each case when the Content-Type header is set, charset will be set to the value of the charset property of the Response instance else, to the value of the charset property of the application.
We are using the Yaml class from the Symfony library, and we have to implement the ResponseFormatterInterface. The implementation of the format method is pretty straightforward, thanks to the intuitive Yaml::dump method. The idea is that we need to set the headers and content fields of the Response instance and not return anything from this method.
To wire this formatter to the Response component, we need to add the formatter's declaration to the components. This is the whole point of the custom response formatters. If you open this route in the browser, it'll open the Save as We included the Content-Disposition: inline header to force the browser to display the data if it's capable of doing so. Let's discuss them in more detail. More than this, asset bundles can depend on other asset bundles, and in this case, a single call to register one top-level "master" asset bundle can result in registering the whole UI for the application.
It means to put the corresponding HTML element into the resulting page and fill its href or src attribute. However, if we store the asset files in some arbitrary folder in the code base, maybe in a place inaccessible by the web server, what URLs do we use? Asset publishing To answer the questions just asked, Yii has the AssetManager class and the concept of asset publishing.
When you use AssetBundle with the sourcepath property defined, the Yii application utilizes the AssetManager component to copy the directory specified by sourcepath to some directory specified in the AssetManager. By default, AssetManager. It will be renamed to a unique, timestamp-dependent hash so that AssetManager will not unnecessarily republish the AssetBundle folder if it has not changed any content at all.
You can get into details of it by reading the official documentation for Yii 2. We will now concentrate on the practical consequences of publishing assets, which are as follows: By default, all the assets are being published in the assets subfolder of your web root.
Usually, you have no reason to change this default setting. You can completely erase the contents of this folder, which holds the assets, at any time without any problem except at the time of copying assets again. You must not delete this folder because Yii never checks for its existence and doesn't create it. The whole AssetBundle. This means that you can have, say, CSS files in the css subfolder that reference the PNG images stored in the img subfolder by using relative paths such as..
This is the same case for fonts. When developing an application, it's meaningless to change files in directory. You have to change the original files in AssetBundle. Yii 2 tries to decide whether it needs to republish assets by comparing timestamps, but it can fail.
So a foolproof way to republish assets is just to purge the assets directory so that Yii will be forced to repopulate it. There is this configuration setting called AssetManager. When it is true, AssetManager doesn't copy the assets folder but makes a symbolic link for it.
It is processed by Yii::getAlias , so it can be any path alias understandable by Yii 2. Here, we see the basepath and baseurl properties. The base path is the path alias to the folder that contains the files relevant to this bundle. The base URL is the absolute URL prefix that should be appended to all the file references so that the browser will be able to properly request it.
The point is that when you use the sourcepath property in your asset bundle, Yii first publishes this source folder and modifies the basepath and baseurl properties of the asset bundle in question for you. As a side effect, it's pointless to use all three properties at the same time as sourcepath will have precedence anyway.
This usage is meaningful when you can tolerate the folders that pre-exist in your web root directory. However, the whole reason to use the asset bundle is to contain the assets relevant to a single library inside a single folder. If you use a lot of asset bundles based on the base path, you will inevitably fill your web root with a lot of different folders from different libraries. And this can become really ugly really fast.
This will lead to a tangled mess of interrelated files and is a maintenance nightmare waiting to happen. Thus, asset bundles based on the source path, in spite of the cumbersome changerepublish cycle, look like a more maintainable and idiomatic solution. One of the most obvious reasons why they are better is the ability to include only those assets that are relevant to the route currently being processed that is, to the page being currently rendered.
There is also the cssoptions property that can be used to set options for the registercssfile calls for CSS files. Create a directory called assets in the root of the code base.
Inside it, create a file called ApplicationUiAssetBundle. As we declared that our assets depend on YiiAsset and BootstrapAsset, we can replace the option of registering them with registering our asset bundle. Themes One of the interesting things built into the rendering system of Yii 2 is the support for themes. Together with the amazingly versatile asset bundle system, Yii 2 gives another level of control over the appearance of the web application under maintenance.
The definition of a theme from the official documentation and DocBlock in the comments is probably the best explanation of this concept ever. Here it is: A theme is a directory of view and layout files. Each file of the theme overrides corresponding file of an application when rendered.
A single application may use multiple themes and each may provide totally different experience. At any time only one theme can be active.
The crucial part is that a theme is a separate set of view files that can override the existing view files. The data that will be sent to the view files from the controller will be the same for all view files, but the view file from the theme can do something completely different with it. With the support of the asset bundle concept, you can not only rearrange the stuff in the resulting page but also restyle it. You can read the exact rules of applying a theme in the documentation; they're not worth long descriptions here.
Let's look at some sufficiently small examples instead. There's no real meaning behind the snowflakes yet. Right now, our SiteController.
Nothing else is needed here. All acceptance tests should still pass after this change. Also, create a SnowAssetsBundle. The resulting directory tree should look like the following files highlighted in green are to be created : [ ]. The URL is After this, we apply the new assets bundle and wrap the text inside the newly styled container in homepage. Now to apply the newly created theme to the site, we need to add the following declaration to the components.
Here is the end result that you should get: It's a bit silly but illustrates the concept well. The real power of themes comes with their dynamic loading based on some condition, which ideally should be done during application loading.
