[FX.php List] How do I contrain a found set?

[Steve Winter]

Hi,

My advice, given that you want to do an OR search for the user entered
criteria, would be to remove the 
   $SearchParams->AddDBParam('Approved', 'Yes');
from the sFX request as at this point you don't want that there (in my view)

Once you've got the data and are at the point that you want to show the
records that have been found to the user, use php to filter the results,
essentially performing the 'find' that you're looking for...

foreach ($SearchData['data'] as $dataKey => $dataValue) {
  if($dataValue['Approved'][0] == 'Yes') {
    // display record here
  }
}

Hope this helps...

Cheers
Steve
