I am trying to build a dropdown filter search for a database and it seems to be that it is conflicting with the logic statements for ascending/descending order I have in place.
When I tried to move the if-statements of the dropdown menu filter above the ascending/descending ordering statements, the filter does not work properly, i.e. when I try to filter for 'Analyzed' it gives me another statuses too.
On the other hand, when i tried to move the if-statements of the dropdown filter below the ordering statements, the filter search works fine but when trying to order the table I get a $sql undefined error.
print("<form action='patients.php' method='get'>");
// cs = case status
print("<select name='cs'>
<option selected='selected' value=''>--Select Case Status--</option>
<option value='1'>Pass</option>
<option value='2'>Failed</option>
<option value='3'>Pass With Error</option>
<option value='4'>Indeterminate</option>
</select>");
// sf = status flagged
print("<select name='sf'>
<option selected='selected' value=''>--Select Flagged Status--</option>
<option value='Analyzed'>Analyzed Case</option>
<option value='New Case'>New Case</option>
<option value='Updated Case'>Updated Case (New Images)</option>
<option value='None'>No Status Flag</option>
</select>");
print("<input type='submit' name='search' value='Search'></form>");
//print("<a href = 'patients.php?case=failed'>View Failed Cases</a><br><br>");
