I don't see the problem with the code. you're testing for the values… so you just need to specify what to do if the requirements are not met.

[lolodede]

it doesnt check if the checkbox are checked or not

[Dormilich]

used your code for a test and it worked.

[lolodede]

yes its working thanks alot wat about how can i tell user to enter value into textbox when they select other
thanks

[Dormilich]

something like

if (in_array('other', $_POST['hobbies']) and !$_POST['other'])
if (in_array('other', $_POST['hobbies']) xor $_POST['other']) // should also work
