The BR Web Scripting Bridge is a PHP class that has the ability to run BR! programs and display the resulting output on a website. Using the BR Web Scripting Bridge, it is easy to create web interfaces to your BR data, and you don't have to know a thing about PHP. Simply drop the BR Web Scripting Bridge and a copy of BR on your web server and start writing your code in BR.

The Method
When a page is requested from your web server, your BR code is executed with a bit of PHP script.
To use the BR Web Scripting Bridge, you simply write BR programs that print to standard out. This output is then returned to the web browser.
We created a reusable PHP file that will call a BR program of the same name. Then you copy the included PHP template file and rename it to match your program name. The php file tells the web server to run your BR program and display the resulting output.
Input to your programs is provided in the form of a set of predefined variables. These variables contain all data that is sent when a form is submitted by the users web browser.
Using these methods, virtually any web application or http service can be built entirely in BR. Your pages can utilize any of the technologies currently seen in web pages such as Flash, JavaScript, and AJAX.
Requirements
Examples
Here are some examples of the BR Web Scripting Bridge in action:
- Example 1: http://www.sageax.com/bridgedemo/adapter.php?BR_SOURCE=src/webcrawl.brs
- Example 2: http://www.sageax.com/bridgedemo/adapter.php?BR_SOURCE=src/csscrawl.brs
- Example 3: http://www.sageax.com/bridgedemo/adapter.php?BR_SOURCE=src/itemlist.brs
- Example 4: http://www.sageax.com/bridgedemo/adapter.php?BR_SOURCE=src/select.brs
Each of the above examples are simple web applications created and controlled by a single BR program.
Each Example consists of a simple three line php file, the BR Web Scripting Bridge, and a single BR program. The .php file is a completely generic .php file. The only thing it does is to find and launch the .br file of the same name. All you have to do is rename it so the name matches the name of your br program.
We named our first example webcrawl, and created a br program called webcrawl to run the example web page. The second example is called itemlist, and it and all the others are identical to webcrawl.
<?PHP
include('class.brphp.php');
$br = new brphp();
$br->RunBrCodeBehind($_SERVER['PHP_SELF']);
?>
The generic php code above simply launches the br code below and displays the output in your browser.
Example 1
http://www.sageax.com/bridgedemo/webcrawl.php
The above website is created from a simple BR program shown below. This example program uses the FileIO Library (not shown) to read data out of my data files in my suite of sample programs and sample data. You choose the data file to view from the drop down. When you press the "View File" button, the php server calls BR and returns the results of the file you chose.

Example 2
http://www.sageax.com/bridgedemo/csscrawl.php
Our first example was simple and exciting but the web page didn't look very nice. For our next example, we're going to take the same program, and apply a Cascading Style Sheet to make it look a little bit nicer.
Cascading Style Sheets, or CSS files, are replaceable templates that affect the overall look, or style, of a web page. When you design a web site, if you put all your style settings in a CSS file, you can change them all later by simply replacing the CSS file, without having to modify the site itself.
Additionally, you can find many CSS files online that you can just drop into your applications.
For this example, we'll be taking a CSS file called style.css that contains a bunch of nice styles for tables. We'll be using it to spruce up the appearance of the tables from the example before.
To use CSS, all we have to do is modify the header to include the style sheet, and modify the tables to use it.
10160 print '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">' 10170 print '<html xmlns="http://www.w3.org/1999/xhtml">' 10180 print '<head>' 10190 print ' <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />' 10200 print ' <link href="style.css" rel="stylesheet" type="text/css">' 10210 print '</head>'
In line 10160, we declare the file as an xhtml file as opposed to a regular html file. In line 10200, we include the style sheet.
10450 print '<table id="hor-minimalist-b" align="center">' 10470 print ' <thead>' 10480 print ' <tr>' 10490 for _Index=1 to Udim(Mat Descr$) 10500 print ' <th scope="col">'&Descr$(_Index)&'</th>' 10510 next _Index 10520 print ' </tr>' 10530 print ' </thead>'
Line 10450 tells the table to use the CSS style "hor-minimalist-b" from the included file.
Notice the <thead> and </thead> tags above. We also need to specify a <thead> and a <tbody>, so that the style knows what to apply to each part of the table.
10550 print ' <tbody>' 10610 print ' <td>'&F$(_Index)&'</td>' 10640 print ' <td>'&Str$(F(_Index))&'</td>' 10700 print ' </tbody>' 10710 print '</table>' 10720 print '</body>' 10730 print '</html>'
We draw the body of the table just like before, adding the <tbody> and </tbody> tags.
Here is the full example. The code is almost identical to Example 1 but looks a lot nicer when you run it.

Example 3
http://www.sageax.com/bridgedemo/itemlist.php
Example 3 demonstrates how to dynamically ask the user for information from your BR program.
This simple BR program reads a list of groceries from the items file and generates a web form where a grocer could order items directly over the internet. The grocer enters quantities in the quantities field for any items he wishes to purchase and presses the "Ok" button when done. The page is submitted again to our program, this time with the MAT _POST$ array populated with all the data the grocer entered into the form. The program processes the data, adding up the quantities and prints out a "Congratulations, your order was successful!" page.
If this were a real life program, you would simply save the new order back into your BR data files.

Example 4
http://www.sageax.com/bridgedemo/select.php
Our next example demonstrates both data entry and multi-program applications.
This example is in three parts, each controlled by a separate BR program.
The first br program and php file are called "select". This BR program simply displays the contents of the colorcat file and ask's a user to select a record from it using radio buttons.
The second BR program and php file are called "edit". This BR program presents the contents of the record the user selected, allowing the user to edit them in a web form.
The third BR program and PHP file are called "save". This BR program saves the changes the user made and prints a confirmation message.
