The method below is producting this debug output.

Debug (StudentSearch_Controller->StudentSearchResults() in line 74 of StudentSearch.php)
waldron
Debug (StudentSearch_Controller->StudentSearchResults() in line 85 of StudentSearch.php)
*

...

   // Get student search results for display on template
   function StudentSearchResults(){
   
      $searchstring=Session::get('SearchString');
      Debug::show($searchstring);
      if ($searchstring="*") {
            $results = DataObject::get('Student','','Lastname,FirstName');
         }
         else {
            $results = DataObject::get('Student',"`Lastname`='".Convert::raw2sql($searchstring)."'",'Lastname,FirstName');

         }
      Debug::show($searchstring);
   return $results;

   }

....

It seems to me that the if statement is setting the value of the searchstring.

Any ideas?

Hi.

It needs to be

if ($searchstring == "*")

There are two equals signs for testing equality. One = is assignment, even in an if-statement.

Thanks Mark. Do you know, I thought of trying that. Don't know why I didn't! I'm New to PHP and I'm to used to my old foxpro syntax days!

Much appreciated.
