3. Fill in the Products – Select Query
List all the items from the database into the empty space shown below in the same format. Column 1 is a radio button and Column 2 is the name of the item. Hence, the value of column-1 (radio button) should be equal to the “id” of the product.
List of items from the DB (Like stuff.php)

4. Page-Page Communication
modify-item.php
update-item.php
id of the selected item
HOW?
Recall the GET method
How does it send values of the form to the PHP file
Use that logic here too

5. Page-Page Communication
modify-item.php
update-item.php
update-item.php?item=

6. Update Page: Retrieve current Info
All information is filled from the database by executing a select query in the top with condition “where id = $_GET[‘item’].

7. Update Page: Execute update
After the user changes the information and presses update
Use the POST method to update the items by running the Update Query
Display the message for success/failure selectively as we did earlier
