- <a href="?page=Database.ActiveRecord">ActiveRecord</a>
- and <a href="?page=ActiveControls.Home">Active Controls</a> to build a Chat
- web application. It is assumed that you
- are familiar with PHP and you have access to a web server that is able to serve PHP5 scripts.
- This basic chat application will utilize the following ideas/components in Prado.
- </p>
- <ul id="u1" class="block-content">
- <li>Building a custom User Manager class.</li>
- <li>Authenticating and adding a new user to the database.</li>
- <li>Using ActiveRecord to interact with the database.</li>
- <li>Using Active Controls and callbacks to implement the user interface.</li>
- <li>Separating application logic and application flow.</li>
- </ul>
-
- <p id="90082" class="block-content">In this tutorial you will build an AJAX Chat web application that allows
- multiple users to communicate through their web browser.
- The application consists of two pages: a login page
- that asks the user to enter their nickname and the main application chat
- page.
- You can try the application <a href="../chat/index.php">locally</a> or at
- <a href="http://www.pradosoft.com/demos/chat/">Pradosoft.com</a>.
- The main application chat page is shown bellow.
- <img src=<%~ chat1.png %> class="figure" />

- <h1 id="18009">Download, Install and Create a New Application</h1>
- <p id="90083" class="block-content">The download and installation steps are similar to those in
- the <a href="?page=Tutorial.CurrencyConverter#download">Currency converter tutorial</a>.
- To create the application, we run from the command line the following.
- See the <a href="?page=GettingStarted.CommandLine">Command Line Tool</a>
- for more details.
-<com:TTextHighlighter Language="text" CssClass="source block-content" id="code_90027">
-php prado/framework/prado-cli.php -c chat

- </p>
-
- <p id="90084" class="block-content">The above command creates the necessary directory structure and minimal
- files (including "index.php" and "Home.page") to run a Prado web application.
- Now you can point your browser's URL to the web server to serve up
- the <tt>index.php</tt> script in the <tt>chat</tt> directory.
- You should see the message "Welcome to Prado!"
- </p>
-
- <h1 id="18010">Authentication and Authorization</h1>
- <p id="90085" class="block-content">The first task for this application is to ensure that each user
- of the chat application is assigned with a unique (chosen by the user)
- username. To achieve this, we can secure the main chat application
- page to deny access to anonymous users. First, let us create the <tt>Login</tt>
- page with the following code. We save the <tt>Login.php</tt> and <tt>Login.page</tt>
- in the <tt>chat/protected/pages/</tt> directory (there should be a <tt>Home.page</tt>
- file created by the command line tool).

-First, we shall setup a database with a <tt>chat_users</tt> table and create an ActiveRecord
-that can work with the <tt>chat_users</tt> table with ease. For the demo, we
-use <tt>sqlite</tt> as our database for ease of distributing the demo. The demo
-can be extended to use other databases such as MySQL or Postgres SQL easily.

-CREATE TABLE chat_users
-(
- username VARCHAR(20) NOT NULL PRIMARY KEY,
- last_activity INTEGER NOT NULL DEFAULT "0"
-);
-</com:TTextHighlighter>
-Next we define the corresponding <tt>ChatUserRecord</tt> class and save it as
-<tt>chat/protected/App_Code/ChatUserRecord.php</tt> (you need to create the
-<tt>App_Code</tt> directory as well). We also save the sqlite database file

- <h1 id="16001">Building a Simple Currency Converter</h1>
- <p id="80053" class="block-content">This tutorial introduces the Prado web application framework and teaches
- you how to build a simple web application in a few simple steps. This
- tutorial assumes that you are familiar with PHP and you have access
- to a web server that is able to serve PHP5 scripts.
- </p>
-
- <p id="80054" class="block-content">In this tutorial you will build a simple web application that converts
- a dollar amount to an other currency, given the rate of that currency
- relative to the dollar. The completed application is shown bellow.
- <img src=<%~ example2.png %> class="figure" />
- You can try the application <a href="../currency-converter/index.php">locally</a> or at
- <a href="http://www.pradosoft.com/demos/currency-converter/">Pradosoft.com</a>.
- Notice that the application still functions exactly the same if javascript
- is not available on the user's browser.
- </p>
-
- <h1 id="download">Downloading and Installing Prado</h1>
- <p id="80055" class="block-content">To install Prado, simply download the latest version of Prado from
- <a href="http://www.pradosoft.com/">http://www.pradosoft.com</a>
- and unzip the file to a directory <b>not</b> accessible by your web server
- (you may unzip it to a directory accessible by the web server if you wish
- to see the demos and test). For further detailed installation, see the
- <a href="?page=GettingStarted.Installation">Quickstart Installation</a> guide.
- </p>
-
- <h1 id="16002">Creating a new Prado web Application</h1>
- <p id="80056" class="block-content">The quickest and simplest way to create a new Prado web application is
- to use the command tool <tt>prado-cli.php</tt> found in the <tt>framework</tt>
- directory of the Prado distribution. We create a new application by running
- the following command in your
- command prompt or console. The command creates a new directory named
- <tt>currency-converter</tt> in your current working directory.
- You may need to change to the appropriate directory
- first.
- See the <a href="?page=GettingStarted.CommandLine">Command Line Tool</a>
- for more details.
- </p>
-<com:TTextHighlighter Language="text" CssClass="source block-content" id="code111">
-php prado/framework/prado-cli.php -c currency-converter
-</com:TTextHighlighter>
-
- <p id="80057" class="block-content">The above command creates the necessary directory structure and minimal
- files (including "index.php" and "Home.page") to run a Prado web application.
- Now you can point your browser's url to the web server to serve up
- the <tt>index.php</tt> script in the <tt>currency-converter</tt> directory.
- You should see the message "Welcome to Prado!"
- </p>
-
- <h1 id="16003">Creating the Currency Converter User Interface</h1>
- <p id="80058" class="block-content">We start by editing the <tt>Home.page</tt> file found in the
- <tt>currency-converter/protected/pages/</tt> directory. Files ending
- with ".page" are page templates that contains HTML and Prado controls.
- We simply add two textboxes, three labels and one button as follows.

- <p id="refresh" class="block-content">
- If you refresh the page, you should see something similar to the following figure.
- It may not look very pretty or orderly, but we shall change that later using CSS.
- <img src=<%~ example1.png %> class="figure" />
- </p>
-
- <p id="80059" class="block-content">
- The first component we add is a
- <com:DocLink ClassPath="System.Web.UI.TForm" Text="TForm" />
- that basically corresponds to the HTML <tt>&lt;form&gt;</tt> element.
- In Prado, only <b>one</b> <tt>TForm</tt> element is allowed per page.
- </p>
-
- <p id="80060" class="block-content">The next two pair of component we add is the
- <com:DocLink ClassPath="System.Web.UI.WebControls.TLabel" Text="TLabel" />
- and
- <com:DocLink ClassPath="System.Web.UI.WebControls.TTextBox" Text="TTextBox" />
- that basically defines a label and a textbox for the user of the application
- to enter the currency exchange rate.
- The <tt>ForControl</tt> property value determines which component
- that the label is for. This allows the user of the application to click
- on the label to focus on the field (a good thing). You could have used
- a plain HTML <tt>&lt;label&gt;</tt> element to do the same thing, but
- you would have to find the correct <tt>ID</tt> of the textbox (or
- <tt>&lt;input&gt;</tt> in HTML) as Prado components may/will render the
- <tt>ID</tt> value differently in the HTML output.
- </p>
-
- <p id="80061" class="block-content">The next pair of components are similar and defines the textbox
- to hold the dollar value to be converted.
- The <tt>TLabel</tt> with <tt>ID</tt> value "total" defines a simple label.
- Notice that the <tt>ForControl</tt> property is absent. This means that this
- label is simply a simple label which we are going to use to display the
- converted total amount.
- </p>
-
- <p id="80062" class="block-content">The final component is a
- <com:DocLink ClassPath="System.Web.UI.WebControls.TButton" Text="TButton" />
- that the user will click to calculate the results. The <tt>Text</tt>
- property sets the button label.

-
- <p id="80063" class="block-content">If you tried clicking on the "Convert" button then the page will refresh

- should extends the

- <p id="80075" class="block-content">If you try the application now, you may notice that the page no longer
- needs to reload to calculate and display the converted total amount.
- However, since there is not page reload, there is no indication or not obvious
- that by clicking on the "Convert" button any has happened.
- We can further refine the user experience by change the text of "total" label
- to "calculating..." when the user clicks on the "Convert" button. The text of
- the "total" label will still be updated with the new calculate amount as before.
- </p>
-
- <p id="80076" class="block-content">To indicate that the calculation is in progress, we can change the text
- of the "total" label as follows. We add a <tt>ClientSide.OnLoading</tt> property
- to the "Convert" button (since this button is responsible for requesting
- the calculation).

-&lt;com:TActiveButton Text="Convert" OnClick="convert_clicked" &gt;
- &lt;prop:ClientSide.OnLoading&gt;
- $('&lt;%= $this->total->ClientID %&gt;').innerHTML = "calculating..."
- &lt;/prop:ClientSide.OnLoading&gt;
-&lt;/com:TActiveButton&gt;

-
- <p id="80077" class="block-content">The <tt>ClientSide.OnLoading</tt> and various
- <com:DocLink ClassPath="System.Web.UI.ActiveControls.TCallbackClientSide" Text="other properties" /> accept a javascript block as their content or value.
- The javascript code <tt>$('...')</tt> is a javascript function that is
- equivalent to <tt>document.getElementById('...')</tt> that takes a string
- with the ID of an HTML element. Since Prado renders its components's IDs, we need
- to use the rendered ID of the "total" label, that is, <tt>$this->total->ClientID</tt>. We place this bit of code within a <tt>&lt;%= %&gt;</tt> to obtain the rendered HTML ID for the "total" label. The rest of the
- javascript code <tt>innerHTML = "calculating..."</tt> simply changes
- the content of the "total" label.

- <h1 id="16007">Adding Final Touches</h1>
- <p id="80078" class="block-content">So far we have built a simple currency converter web application with
- little attention of the looks and feel. Now we can add a stylesheet
- to improve the overall appearance of the application. We can simply
- add the stylesheet inline with the template code or we may create
- a "theme".
- </p>
-
- <p id="80079" class="block-content">To create and use a theme with Prado applications, we simply create a new
- directory "themes/Basic" in the <tt>currency-converter</tt> directory.
- You may need to create the <tt>themes</tt> directory first. Any
- directory within the <tt>themes</tt> are considered as a theme with the
- name of the theme being the directory name. See the
- <a href="?page=Advanced.Themes">Themes and Skins</a> for further details.
- </p>
-
- <p id="80080" class="block-content">We simply create a CSS file named "common.css" and save it in the
- <tt>themes/Basic</tt> directory. Then we add the following code
- to the beginning of "Home.page" (we add a little more HTML as well).
