CheckboxNDropDownMenuValidation In PHP

[Anon]

Is there any way to validate a checkbox?Say I have a discussion board, and I would like the user to agree to the Terms Of Use before signing up? How about pull down menu(drop down box) validation?Just because I want to make sure that the users select at least one of the options. In these cases, I hope that all the works can be done by using ONLY PHP language, but not JavaScript.
Further comments and solutions will be appreciated.Thanks.

(P/S: Oh sorry, is my question clear enough?)

Check Box:
Just use the isset() function to check the value of the check box. If it returns true then you know it was checked.

Select Drop Down:
Set the first value of the select drop down to an empty string. Use the isset() function again to see if something has been selected or you can use the strlen() function to see the size of the string.

Hope this helps..
