Question

That’s the first time i get an error like this one, let me explain :

Here is my code :

function printSiteIndexedItems($co, $id){
  global $allSections;
  foreach($allSections as $aSection => $aSectionName){
   $tr = $co->prepare("SELECT COUNT(id) FROM ". $aSection ." WHERE site=:id AND valide=1");
   $tr->bindParam(':id', $id, PDO::PARAM_INT);
   $tr->execute();
   if($indexedItems = $tr->fetchColumn()) echo '<p>'. $aSectionName .' : '. $indexedItems .'</p>';
  }
 }

The first iteration works just fine, it prints what i want (a category name and the number of elements in it).

But after that first iteration, i get this classic error :

Fatal error: Call to a member function bindParam() on a non-object in

Indeed, $co is a valid PDO object as it works for the first iteration. But it seems that as soon as we enter the second one, it no longer is ? 😮

I’m kinda new with PDO, so maybe it’s a normal behavior i didn’t acknowledge yet. Please help ! =)

Looks like $co->prepare... returns FALSE for at least one of the stamtents you try to prepare.
Either test if ( !$tr ) .... or set $co->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); to get an exception when PDO encounters an error.
