Function not returning variable

[cmgmyr]

Hey Guys,

I have no idea why this function is not returning the variable $new_cats, it's echoing correctly, but nothing is getting returned. Am I missing something??? Thanks!

 

Category Function:

function getCategories($cat_id, $level=0, $cats='') {  
	global $db;

	if($level == 0){
		$cats = array();
	}

	$sql = "SELECT parentid, name FROM categories WHERE id = $cat_id";
	$result = $db->query($sql);
	list ($p, $n) = $db->fetchRow($result);

	$cats[] = $n;

	if ($p != '0') $this->getCategories($p, $level+1, $cats);

	if($p == '0'){
		krsort($cats);			
		$new_cats = '';
		foreach($cats as $cat){
			$new_cats .= "$cat » ";
		}

		$new_cats = substr($new_cats, 0, -9);

		echo $new_cats;

		return $new_cats;
	}
}

 

test page:

if($cats = $catalog->getCategories(62)){
	echo $cats;
}else{
	echo '<br /><br />No cats!';
}

echo $new_cats instead of $cats on your test page or after return.

But if I'm setting the returned value = $cats there shouldn't be any reason why it's not showing up. I even tried doing "return true;" instead of the variable and it still didn't return anything.

What does the echo $new_cats; produce?

[cmgmyr]

the echo is just to see if the function is working but for 62 it echos "Anniversary & Wedding » Diamond » Center Stone". I tried commenting out the echo statement, but that didn't change anything.

If it doesn't return anything at all even when you return true then the problem lies here:

<?php
if($p == '0'){
?>

 

Are you sure that this if statement is evaluating correctly (is $p always '0')?

[trq]

If thats what is being echo'd then theres no reason its not being returned. Sorry.

@ Sulman - if it wasn't correct the I wouldn't be seeing the echo statement either

 

@ thorpe - that's what I thought too but for some reason it's not, I'll keep messing with it.

 

Thanks guys

What does the test page produce? Does it say no cats or is it blank or something?

[cmgmyr]

it echos "No cats!"
