1. >> PHP: Delete Query

2. Update Page: Execute update
Continued…....
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
HINT: Use the same approach as the INSERT QUERY

3. Update Image Two cases If Image is updated If Image not updated
Image Updated
Image Not Updated
If Image is updated
Same steps as UPLOAD IMAGE
Use $_FILES Associative Array
If Image not updated
How to know if image was not updated?

4. Image Not Updated Check if $_FILES is not set? Will this work? No.
If enctype is set, the $_FILES is sent but empty
Other Approach
Check if $_FILES is empty
Cannot check if the whole array is empty
Check if any one of the dimension is empty
For example
$_FILES[‘name’] === “”

5. Delete Query
Within the same page as modify-item.php, write code for delete (use isset($_POST[‘delete’])
Run the Delete Query
Display confirmation that the item was deleted successfully
