If you mean removing the if condition, i already tried it too

$vbulletin->input->clean_gpc('userfield', TYPE_ARRAY);

$fieldcontentbefore = array(
'aaa',
'ccc'
);

$fieldcontentafter = array(
'bbb',
'ddd'
);


$vbulletin->GPC[field1] = str_replace($fieldcontentbefore, $fieldcontentafter, $vbulletin->GPC[field1]);

or this

$vbulletin->input->clean_gpc('userfield', TYPE_ARRAY);

$fieldcontentbefore = array(
'aaa',
'ccc'
);

$fieldcontentafter = array(
'bbb',
'ddd'
);


$vbulletin->GPC['field1'] = str_replace($fieldcontentbefore, $fieldcontentafter, $vbulletin->GPC['field1']);

but still not replacing too, you can try it in your vb3 test site, or i can give a vb3 test site access if you like
