Online Contacts Directory
For this assignment you need to design and implement an online contacts directory that can be used to
retrieve different types of contact information including phone number(s) and address data. This directory
may prove beneficial as once it is available on the web, you can access this information from any net
enabled device. In addition, as you may get new or updated information on a contact while away from
your home computer, having the ability to add new contacts or update existing contacts wherever a net
enabled is available may also prove beneficial. Similar applications to this are Google Contacts, iCloud
Contacts, and Microsoft Office 365.
Design Requirements
You should create an online contacts directory application that saves entries to a single text file. Include
standard contact directory fields in the text file such as first name, last name, email address, phone
number, street address, city, state, and zip code. You will want to plan how to save this data to the file for
easy retrieval. Hint: Your textbook may provide helpful insights.
As part of your application, one web page will serve as a main directory, where you can search and
retrieve records along with a document that allows you to add contacts. You should have another web
page that you can use to edit contacts. All pages should allow the user to return to the main directory.
Below is an example of the main directory output you should have before formatting:
Whether a user is searching, adding a new entry, or updating an existing contact you should verify that
they have entered a value in each field. If the have not, then you should indicate this to them via serverside
scripting. When an entry has been successfully saved or updated then you should tell the user. If a
search, save, or update was not successful then you should indicate this to the user. You should also
alert the user if the text file containing the contacts does not exist.
On the next page is an example of one of the error outputs you should have before formatting:
On each entry form, the state field must be set up using a <select> drop-down list as shown in the
example diagram. In addition, the update page must pre-select the state previously saved along with prefilling
all the other fields with the values previously saved.
Below is an example of the edit entry and add entry output you should have before formatting:
Whenever you are writing data to the file, you should appropriately lock the file to prevent a mismatch of
data being saved. If the file cannot be locked then you should alert the user to retry submitting the form in
a few moments as other updates are being performed. Constants should be used for values that do not
change, and variables for values that change during the course of execution. You should include Last
Modified Date information on your page. This should be provided dynamically by using the built-in
date()function within the getlastmod()function.
At the point of final submission, your application should be laid out in the Lab Content area of your web
site. When laying out your web page, you should retain the common navigation and structural
components (header and footer) of your website even though not shown in the image. This will require
you to incorporate the SSI file references in this lab assignment as you did on previous the lab
assignment. SSI files should not be moved but rather you should provide the path to their original file
location. The common navigation and structural components should present visual continuity across all
the web pages of your website and should not shift at all when going from web page to web page. In
addition, while the image does not demonstrate this, you need to include a working link on each page to
get back to your home page. Each page of the assignment should load into the Lab Content area only.
For the main directory page, you should use a file name that will automatically load when a user
specifies only the folder name in the URL. The file should be uploaded to your Lab Assignment 3
directory. Your XHTML file should be well-formed and created using a strict XHTML DTD. You can
create the web page using any text editor (Microsoft Notepad, RogSoft Notepad+, Adobe Homesite, etc)
that is not WYSIWYG capable (Adobe Dreamweaver, Microsoft Word, etc).
You should use XHTML for the content of all pages and CSS for the stylizing and positioning of each of
the pages. Using an external .css file, add formatting of your choice to make the output more
aesthetically pleasing. These styles should be implemented as part of the early submission points. While
you should continue to use the external CSS you created for your home page, you should not modify or
update the file. Your new CSS file should not conflict or modify the layout and positioning of earlier lab
assignments.
Approach
For the first submission point, create a simple XHTML page for all the pages of the online contact
directory. These pages contain no PHP however some of them will have forms that submit to a separate
.php script files. Create a text file with starting records that correspond to the order of the form fields for
contact names, addresses, etc.
After creating the non-PHP XHTML pages, you may want to start by determining, coding, and validating
the .php files using XHTML (and absent of any CSS). You can simply assign a record to an array for
early functional testing. As part of this, and after the first submission point, begin to populate these arrays
with the contents of the file instead. Add the ability to write to the file. Once working like the output given,
you can begin adding the CSS formatting. Finally, validate all the pages and correct any ill-formed tags
where necessary.
Submission
You will need to upload these web/script pages and CSS file to your Lab Assignment 3 directory within
your Zeus/Helios server space, while keeping the original SSI and CSS files in their original file location.
Verify that all the uploaded pages work in the browser, as this is what will be used for grading. Also for
each submission point, you must submit all the files you create to the appropriate Assignment drop box
on Blackboard.
