Dreamweaver and dynamic page design
Follow
these general steps to successfully design and create a dynamic
website.
Design the page.
A key step in designing any website—whether
static or dynamic—is the visual design of the page. When adding
dynamic elements to a web page, the design of the page becomes crucial
to its usability. You should carefully consider how users will interact
with both individual pages and the website as a whole.
A common
method of incorporating dynamic content into a web page is to create
a table to present content, and import dynamic content into one
or more of the table’s cells. Using this method you can present
information of various types in a structured format.
Create a source of dynamic content.
Dynamic websites
require a content source from which to extract data before they
can display it on a web page. Before you can use content sources
in a web page, you must do the following:
Create a
connection to the dynamic content source (such as a database) and
the application server processing the page. Create the data source
by using the Bindings panel; then you can select and insert the
data source in the page.
Specify what information in the database you want to display,
or what variables to include in the page by creating a recordset.
You can also test the query from within the Recordset dialog box,
and make any needed adjustments before adding it to the Bindings
panel.
Select and insert dynamic content elements into the selected
page.
Add dynamic content to a web page.
After you define
a recordset or other data source, and add it to the Bindings panel,
you can insert the dynamic content the recordset represents into
the page. The Dreamweaver menu-driven interface
makes adding dynamic content elements as easy as selecting a dynamic
content source from the Bindings panel, and inserting it into an
appropriate text, image, or form object within the current page.
When
you insert a dynamic content element or other server behavior into
a page, Dreamweaver inserts a server-side
script into the page’s source code. This script instructs the server
to retrieve data from the defined data source and render it within
the web page. To place dynamic content within a web page, you can
do one of the following:
Place it at the insertion
point in either Code or Design view.
Replace a text string or other placeholder.
Insert
it into an HTML attribute. For example, dynamic content can define the
src attribute of an image or the value attribute of a form field.
Add server behaviors to a page.
In addition to adding
dynamic content, you can incorporate complex application logic into
web pages by using server behaviors. Server behaviors are predefined
pieces of server-side code that add application logic to web pages, providing
greater interaction and functionality.
The Dreamweaver server behaviors let you add
application logic to a website without having to write the code
yourself. The server behaviors supplied with Dreamweaver support ColdFusion, ASP, and
PHP document types. The server behaviors are written and tested
to be fast, secure, and robust. The built‑in server behaviors support
cross-platform web pages for all browsers.
Dreamweaver provides a point-and-click interface
that makes applying dynamic content and complex behaviors to a page
as easy as inserting textual and design elements. The following
server behaviors are available:
Define a recordset
from an existing database. The recordset you define is then stored
in the Bindings panel.
Display multiple records on a single page. You select either
an entire table or individual cells or rows that contain dynamic
content, and specify the number of records to display on each page
view.
Create and insert a dynamic table into a page, and associate
the table with a recordset. You can later modify both the table’s
appearance and the repeating region by using the Property inspector
and Repeating Region Server Behavior, respectively.
Insert a dynamic text object into a page. The text object
you insert is an item from a predefined recordset, to which you
can apply any of the data formats.
Create record navigation and status controls, master/detail
pages, and forms for updating information in a database.
Display more than one record from a database record.
Create recordset navigation links that allow users to view
the previous or next records from a database record.
Add a record counter to help users keep track of how many
records were returned, and where they are in the returned result.
You
can also extend Dreamweaver server behaviors
by writing your own, or installing server behaviors written by third
parties.
Test and debug the page.
Before making a dynamic page—or
an entire website—available on the web, you should test its functionality.
You should also consider how your application’s functionality might
affect people with disabilities.
