Radio Button updating code further on

demosthenes705

I have the following code

$path = ("public_html/scn/$grade");

what i need to do is in my form I need 4 radio buttons from 9-12 grade so when they select one it will update the $grade. All i need is an example or something. I can fill it in if i get 1 section of code.

You have:
[font=courier new]<input type="radio" name="grade" value="9" />[/font]

When you POST this to a PHP script, you will then have $POST['grade'], which has the value 9. You can then use:
[font=courier new]$path = 'public_html/scn/' . $POST['grade'];[/font]

But be aware that, since this is user input, you should probably check that it's a number, or you open a potential security hole:

$grade = intval($_POST['grade']);
$path = 'public_html/scn/' . $grade;

really, even with radio buttons there a security potental leak. but its just teachers and theres no admin panel so i don't think anything of it. But i am thinking of makeing an admin panel. basically sign up, and delete, and maybe post news

You should still check. If the valid values are 9, 10, 11, 12, then those are the only values you should accept, and be prepared to reject anything else. Even if this an intranet inaccessible to the world at large. Unless you're confident that these teachers are all sufficiently security-conscious that they never walk away from the computer while it's turned on.
