SQL injection PHP - part 3 - Deleting data from database

In this vedio I am going to explain how you can delete all the data from the database, by running SQL injection.
To do this we are using one form, one database and some PHP code,
our code is vulnerability to sql to sql injection because
we are using same name for database column and same name for input, in the form
we using user input directly into our query and we are running multi query into our database.
