You have to run the query because field26 in the user info does not contain the actual data, just the bitfield data. All you get in the bitfield is 1's and 0's. Basically you have to match the real array with $userinfo[field26].

To visualize may be easier... imagine your array with "Yes", "No" and "Maybe" values (in that order in your custom field manager), which is contained NOT in userinfo[$field26] but in $my_custom_data as outlined above. $my_custom_data looks like this:

$my_custom_data[0] = "Yes"
$my_custom_data[1] = "No"
$my_custom_data[2] = "Maybe"

Now, $userinfo[field26] looks like this when "Yes" is set (in binary):
001 (or simply "1", but the leading zero's may help you visualize here)

So when you compare the fields with " if ($userinfo[field26] & pow(2,$key)" you are essentially doing this:

$my_custom_data[0] = "Yes" 1 (YES, user has it)
$my_custom_data[1] = "No" 0 (No, User doesnt have it set)
$my_custom_data[2] = "Maybe" 0 (No, User doesnt have it set)

Now, imagine Yes and Maybe are set for this user. $userinfo[field26] will be set to "5" in decimal, and when converted to binary is "101"... ON, OFF, ON... so lets compare it to $my_custom_data:

$my_custom_data[0] = "Yes" 1 (YES, user has it)
$my_custom_data[1] = "No" 0 (No, User doesnt have it set)
$my_custom_data[2] = "Maybe" 1 (YES, user has it)

Likewise, the code you posted:

$my_custom_data = unserialize($userinfo['field26']);
foreach($my_custom_data AS $key => $val) 
{ 
if ($userinfo[field26] & pow(2,$key)) 
{ 
	 $show[testbit] .= $val.", ";
}
}

...Will not work, because the data that is in $userinfo[field26] is NOT the serialized data, it only hold the binary representation to what is set when compared to the real serialized data. Therefore, you MUST run a query, unless vB already has pulled the data.

In your case, around line 560 in member.php

$customfields = '';
while ($profilefield = $db->fetch_array($profilefields))
{
	exec_switch_bg();
	$profilefieldname = "field$profilefield[profilefieldid]";
	if ($profilefield['type'] == 'checkbox' OR $profilefield['type'] == 'select_multiple')
	{
		$data = unserialize($profilefield['data']);
		foreach ($data AS $key => $val)
		{
			if ($userinfo["$profilefieldname"] & pow(2, $key))
			{
				$profilefield['value'] .= iif($profilefield['value'], ', ') . $val;
			}
		}
	}

...Which means, you could use the already queried $userinfo["$profilefieldname"], but ONLY if it's not hidden. I take it your data is hidden, therefore you could either unhide and create some template conditionals, or you add this query.

Hope this helps.
