PHP, double-if statement (?)

Goodshape

Never sure to post PHP questions here or in the Web/Flash forum.. I'll try here for a change.

Here's the code I've got :

	foreach ($channels as $channel) {
		if ($channel["Category"] == $cat){
			if ( ! isset($channel["NotPublic"]) || ! $channel["NotPublic"] || valid_user() ) {
				$out[] = theme_guide_summary_wrapper($channel, theme_guide_summary($channel, $files, 4), $files);
			} // if
		} // if
	} // foreach

What I want is for the first IF statement ($channel["Category"] == $cat) to only be called if $_GET is set.

Something like this ugly piece of code :

	foreach ($channels as $channel) {
	if (isset($_GET["cat"])) {
		if ($channel["Category"] == $cat){
	}
			if ( ! isset($channel["NotPublic"]) || ! $channel["NotPublic"] || valid_user() ) {
				$out[] = theme_guide_summary_wrapper($channel, theme_guide_summary($channel, $files, 4), $files);
			} // if
	if (isset($_GET["cat"])) {
		} //if
	}
	} // foreach

But that doesn't work, obviously.

Any help would be great,
cheers.

It's an easy enough problem, so I'll just give a coupla hints.

Look at line 4 of your second block of code (the one where you only want the other ifs to happen if the first if is true):

Is that closing brace what you want? Are the others as nested as you think?

Think on those bits, and you'll find your answer.

Aoife - who's not giving the answer straight off due to a personal motto of "You never really know how something works until you break it".

Yeap, that would be an easy one then.

Cheers

(don't believe how stupid that second block of code was... ffs! )
