mgd_fetch_to_array()

This is a small helper function, that allows you to transform a fetchable to an ID-Array. Just for your convenience.

Calling Syntax

array mgd_fetch_to_array (object $fetchable);

Parameter Syntax

$fetchable must be an Midgard-Object, that can be traversed by calling $fetchable->fetch(). The Objects must have a member "$fetchable->id" which identifies the primary key. These keys are put together into an Array leaving the sorting order intact.

Variants

Two special cases of this function exist: mgd_memberships_to_uid and mgd_memberships_to_gid. You can use them to transform Membership-Records into User- ord Group-ID Lists. (Who needs Membership Records...) Using those two functions always in conjunction with mgd_list_members and similar, you can avoid a lot of errors...

Hints

Since it does some error checking, you can combine these calls to something like:

$articles = mgd_fetch_to_array(mgd_list_articles(...));

Code


<?php



function mgd_fetch_to_array ($fetchable) {

  $result = array();

  

  if (!$fetchable)

    return false;

  

  while ($fetchable->fetch())

    $result[] = $fetchable->id;

  

  return $result;

}



function mgd_memberships_to_uid ($fetchable) {

  $result = array();



  if (!$fetchable)

    return false;

  

  while ($fetchable->fetch()) 

    $result[] = $fetchable->uid;

  

  return $result;

}



function mgd_memberships_to_gid ($fetchable) {

  $result = array();

  

  if (!$fetchable)

    return false;

  

  while ($fetchable->fetch())

    $result[] = $fetchable->gid;

  

  return $result;

}
