  I am using this code to sort some of my arrays and I was wondering if someone could help me add it to my pnuserapi.php. Also how would I call it from pnuser.php? It works great puting in side the function but I would like to keep everything compliant if possible. Thanks in advance.
  
  

  Code

  //Array Sort Function from http://www.zend.com/codex.php?id=501&single=1
  //metanurb
  function aasort(&$array, $args) {
      foreach($args as $arg) {
          $order_field = substr($arg, 1, strlen($arg));
          foreach($array as $array_row) {
              $sort_array[$order_field][] = $array_row[$order_field];
          }
          $sort_rule .= '$sort_array['.$order_field.'], '.($arg[0] == "+" ? SORT_ASC : SORT_DESC).',';
      }
      eval ("array_multisort($sort_rule".' &$array);');
  }
  /*
  Syntax: aasort($assoc_array, array("+first_key", "-second_key", etc..));
  
  Example: aasort($db_array, array("+ID", "-AGE", "+NAME"));
  Where the "+" in front of the keys stands for "ASC" and "-" for "DESC".
  */

  Functions is the userapi need to be named <module>_userapi_function. The function then takes an arguments array.
  
  So the function looks like
  

  Code

  function <yourmodulename_userapi_yourfunctioname($args)
  {
      // Get arguments from argument array - all arguments to this function
      // should be obtained from the $args array, getting them from other
      // places such as the environment is not allowed, as that makes
      // assumptions that will not hold in future versions of PostNuke
      extract($args);
  
  ......
  
  }

  
  
  The function is then called using a call to pnModAPIFunc('modulename', 'type', 'func', argsarray) having first loaded the user API
  
  loading and calling a function is
  
  

  Code

  ......
      // Load API.  All of the actual work for the creation of the new item is
      // done within the API, so we need to load that in before we can do
      // anything.  If the API fails to load an appropriate error message is
      // posted and the function returns
      if (!pnModAPILoad('module', type')) {
          pnSessionSetVar('errormsg', _LOADFAILED);
          return $output->GetOutput();
      }
  
      // call the apu function
      $mid = pnModAPIFunc('module',
                          'type',
                          'function',
                          array('parameter1' => $paramter1,
                                 'parameter2' => $paramter2,
                                 etc..... ));
  .......

  
  
  -Mark</module>

  Hey mark, been a while.. I understand the format it should be in. I just can get the original function converted over and call it properly.. Probably figure it out like always right after I send this post off.. Thanks again.

  In which case it would be something like
  
  

  Code

  function <module>_userapi_aasort($args)
  {
      $returnarray = array();
      foreach($args as $arg) {
          $order_field = substr($arg, 1, strlen($arg));
          foreach($array as $array_row) {
              $sort_array[$order_field][] = $array_row[$order_field];
          }
          $sort_rule .= '$sort_array['.$order_field.'], '.($arg[0] == "+" ? SORT_ASC : SORT_DESC).',';
      }
      eval ("array_multisort($sort_rule".' $returnarray);');
  
      return $returnarray;
  }

  
  
  -Mark

  Thanks once again but I'm having a heck of a time getting the arguments over to the API. The function is looking for $array and $args. I have tried
  
  

  Code

  $returnarray = pnModAPIFunc('Wdpool',
                          'user',
                          'aasort',
                          array('array' => $fortiebreaking,
                                 'args' => $sortbys));

  
  
  I have also tried changing the function to look for $sortby instead of $args and I still get Invalid argument supplied for foreach()
  That is for the frist foreach that looks for the $args or $sortby array.

  I got it working. Thanks again for your help Mark.. Here is what I got incase anyone else was following this thread. I wish I would have found this function months ago, would have saved me a lot of time and trouble with sorting these arrays..
  
  

  Code

  $sortbys=array("-field1", "+field5");
  
      // call the apu function
      $returnarray = pnModAPIFunc('modname',
                          'user',
                          'aasort',
                          array('array' => $arraytosort,
                                 'args' => $sortbys));

  
  
  

  Code

  function modname_userapi_aasort($args)
  {
  extract($args);
      $returnarray = $array;
      foreach($args as $arg) {
          $order_field = substr($arg, 1, strlen($arg));
          foreach($array as $array_row) {
              $sort_array[$order_field][] = $array_row[$order_field];
          }
          $sort_rule .= '$sort_array['.$order_field.'], '.($arg[0] == "+" ? SORT_ASC : SORT_DESC).',';
      }
    //  eval ("array_multisort($sort_rule".' $returnarray);');
  eval ("array_multisort($sort_rule".' &$returnarray);');
      return $returnarray;
  }
