In this video I want to add the error message system. We will check if it is “set” and we will use the “switch” statement.

The PHP “switch” statement act like a “if” statement. It is used to perform different actions based on different conditions.

Use the switch statement to select one of many blocks of code to be executed.

This is how it works:

The expression is evaluated once
The value of the expression is compared with the values of each case
If there is a match, the associated block of code is executed
The break keyword breaks out of the switch block
The default code block is executed if there is no match

So let’s add this to the categories dashboard page.
