OOP & While

Hi Folks

I'm super new to using OOP (for example having recently discovered
that public functions don't therefore need to be inherited! horray) -
I have come across this issue.

Within my class is a private function which returns a Zend_db fetchAll
SQL query as an array.

Another function then needs to make repeated calls to the above
function, and the code below is what I'm using to do this:

while ($row = $search->fetch()) { // fetch comes from Zend_db
$cid = $row['Company_ID'];
$test = $this->allowedImages($cid); // allowedImages returns an
array of results
print "$cid-{$test[1]}
";
}

I expect about 12 results and if I comment out the $test line it does
so, however without the comment markers it only returns 1 result. Am I
missing how to refer to a function multiple times but with different
results?

Thanks in advance.

You would have to do this:

while ($row = $search->fetch())
{
$test = $this->allowedImages($row['Company_ID']);

for($i = 0; $i < count($test); $i++)
{
echo $test[$i] . '
';
}
}

Hi,

Thanks for that. Yep - fixed it. Interested to know why $test has
become an array considering row['Company_ID'] is a unique number - but
thanks again.

Being daft - of course - its adding to the previous array for each row
rather than created a new one - hence you needed the foreach. Thanks!
