I have a situation which I 'think' I need to use variable variables and
not sure how to go about it.

I have several <select multiple> elements on a search form with their
names created dynamically and the options created dynamically.

$parent holds the name such as "Women", "Mens" etc..
$c_id holds category_id and is sent off as the 'value' of the option.

This form is self calling and an array is created for the multiple
option selected.

Women => array([0]=>20,[1]=>21,...)
Mens => array([0]=>32,[1]=>35,...)

I am using in_array() to check returned posted values against an id.

How do I reference that array by using the value of $parent.

if $parent is 'Women' I need to reference the array 'Women'

Here is a nutshell of the algorithm.

foreach($parent_ary as $parent) {
echo "<select {$parent}[] multiple>";
foreach($category_ary as $c_id=>$category) {
if(in_array($c_id, array of posted value)) {
// Create select option
} else {
// Create regular option
}
}
echo "</select>";
}

I hope this makes sense and yes I did RTM but could not transpose what
they where explaining to what I need to do.

Thanks
Scotty
