foreach generates php warnings

chucklarge

I won't even try to explain what i am doing with this. It works as i need it to but the foreach generates warnings saying 'Invalid argument supplied for foreach() ' in my apache error logs.

can anyone tell me what i am doing wrong with these loops?

thanks, chuck

$_POST is not an array, or
b. One or more of its values is not an array, or
iii. One or more its values' values is not an array.

If you can find a way to identify which line triggers the error you'd know which of the above applies.

AcousticJames

Well, $POST is an array, as long as there are values from a form on a previous page. If you haven't submitted a form using post, then $POST will indeed be empty. Other than that, you need to make sure that each variable you are expecting to be an array is indeed an array.

Yes, that's very true, AcousticJames. I couldn't have said it better myself.
