generate a csv template

[eluser]behnampmdg3[/eluser]
Hi;

I need to generate a csv template for users based on the value of the columns in the table's row.

For example lets say the table has 3 columns:

id, name_selected, email_selected.

For row id = 8, if the value of name_selected = 1, I need to add name to the csv.

Same if the value of email_selected is 1, I need to add email to the csv.

Would you please guide how I can do this.

Thanks.
