Exercise 5:
• Create a PHP file named Exercise5.php in the practicals/week10 folder of your TWA web site.
• Combine the code from exercise4.html and exercise4.php into Exercise5.php (this is similar to exercise 3 in week 7 practical exercises) so that the php script and the html form are in the same file.
A. Modify the code so that
i. The form uses postback (ie, the form action is the same file exercise5.php)
ii. Only the form is displayed on first load of the page
iii. The table of products is only displayed when there are records to display
iv. The form and the messages as described in exercise 4 are displayed when appropriate in appropriate locations
v. The value that the user enters in the form is maintained in the text box after form submission
For further information all errors and the table of products must be displayed on the same page as the input, not on a separate page.

Any help would be greatly appreciated.
Thankyou =)
P.s Sorry for the small error message image, I tried to resize it, but for some reason it would not work.
Just zoom in the page
