Assuming title is the error then $objArray is empty

Of course it's a PHP script. That's why you posted it in the PHP forum.
That foreach requires that first argument to be an array expression. That's why I asked if you are sure that your first argument is an array.

[code green]

Has somebody upset rashgang?

[r035198x]

Has somebody upset rashgang?

I don't think so(not sure actually).

[Markus]

Rashgang, you have been told previously to use code tags in this thread!. You have now received a warning, and a continuation of this behaviour will typically result in a ban of some sort. It is in your best interests to follow the Posting Guidelines.

I'd love to help but I can't bothered to find the line.

Use code tags and you get line numbers and people are much more likely to help you out.

rashgang, you are precariously close to border between ignorance and justified newby-ness. You have, in 4 posts, double posted and not once used code tags - something you were previously warned about. Therefore, this is your second formal warning. Please take note of this or you may receive a ban.

Posting Guidelines - read them.

thank u for ur advice then i have tagged the php see clearly i have used code tags for example <?php

If you look at post 3 you will see I explain what code tags are.
