Hello there,

I added a customfield to a view and used 

<?php
print var_export($data, TRUE);
?>

to print out the available $data

then is put 

<?php
print count ($data->node_data_field_members_field_members_uid);
?>

in the customfield.

If you look at the attachment you will see that some of counts are incorrect.

Anyone any ideas what's going on?

Seems the customfield is counting Null as a value:

stdClass::__set_state(array( 'nid' => '1', 'node_title' => 'A4E Scotland Ltd', 'node_type' => 'guide_organisation', 'node_vid' => '173', 'node_data_field_members_field_members_uid' => array ( 0 => array ( 'uid' => NULL, ), ), ))

the output from 

<?php
print var_export($data, TRUE);
?>

Tried:

<?php
if (!is_null($data->node_data_field_members_field_members_uid))
print count($data->node_data_field_members_field_members_uid);
?>

Should I go back to php school? :)

Solved,

Getting rid of Null aint so easy, here's how to do it:

<?php
$aResult = array();
foreach ($data->node_data_field_members_field_members_uid AS $item)
{
    if (!is_null($item['uid']))
    {
        $aResult[] = $item;
    }
}  
print count($aResult);
?>
