Implement, Test & Document A Simple Login System- P4
Statement Of Need
A simple login system like the one I implemented into my website would be useful in a wide
range of scenarios in which website developers or owners want access to a certain part of a
website which they do not want others to have access to.
For example if a website developer wanted easy access statistic information he may place a
link to view such information on the website itself however have a simple login system
implemented onto the landing page of the linked website so that only people who have the
correct login credentials would be able to view the statistic information.

Fix
The login page displayed
the correct information.
No fix required.
The login php was failing to
connect to the database on
sql due to incorrect
information therefore the
php did not know what the
correct login credentials
were.
I corrected the information so
that the php was able to
connect to the database
where login credentials were
kept, after this the protected
page was loaded after the
correct credentials were
inputted.
No fix required.
The correct message was
outputted.
The logout php was linking
to the wrong page and
instead loading the
protected page.
I changed what page the
logout php was linking to and
this fixed the issue.

How
The login page.
There could be an option added on to
the page which acts as a hint towards a
password or a way to reset a password.
By adding hint towards the password on the
login page which shows up when the user
clicks on a “forgotten password button”.
The protected
page.
The protected page is not formatted like
the rest of the website meaning that the
links to other pages are not available on
the page, therefore it would be better if it
was formatted like the other pages.
By adding the same lines of code which are
included on the other pages of the login
system.
The logout
button.
The php for the logout button is currently
stored in a separate php file to the
protected file however it would be
simpler to have the php code for the
button situated in with the protected file
code.
By moving the code for the logout button
from logout.php to protected.php.

website. This is because both users and website owners would be able to view the
messages.
For example hotel websites may want a guest book system in place so that visitors are able
to leave positive reviews which will inturn attract more customers or because they may want
to use the customers feedback to make improvements to their business. Such a system
would also be a way to get in contact with members of staff from the hotel so it could also be
used as a way for customers to ask any questions about the hotel they may have.

Statement Of Need
A dynamic login system like the one I implemented into my website would be useful in a
wide range of scenarios including ones where websites have a requirement to store
information about a user and want that information be secure and accessible to the user
only.
For example on forums there is a need to identify who people are by using usernames, for
these usernames to be created a user must first create an account and this account would
be required to have a password connected to it, the username and password for this account
would then be stored in a database.
