#where you are running mysqli_query , add 'or die( mysqli_error($db)' #e.g $sql = "SELECT * FROM users"; $result = mysqli_query($db, $sql) or die( mysqli_error($db)); #$db being the variable holding the connection to db
Here is what the above code is Doing:
1. It’s creating a variable called $sql that holds the SQL query.
2. It’s running the query and storing the result in a variable called $result.
3. It’s checking to see if the query ran successfully. If it didn’t, it’s printing out the error message.
