I'm trying to pull a load of setting from a database table, and I'm trying to add the returned records to an existing array by using:-
array_merge($arrPrivileges,array($rowPrivileges['setting']->$rowPrivileges['value']));

Open in new window


However all Im getting back is "Trying to get property of non-object".

      function getPrivileges($userID,$section) {
        $resPrivileges = parent::query("select * from `userPrivs` where `userID`='" . mysqli::escape_string($userID) . "' AND `page`='" . mysqli::escape_string($section) . "';");

        $arrPrivileges = array();

        if ($resPrivileges->num_rows > 0) {
          while ($rowPrivileges = $resPrivileges->fetch_array()) {
            array_merge($arrPrivileges,array($rowPrivileges['setting']->$rowPrivileges['value']));
          }
        }
        return $arrPrivileges;
      }


var_dump(getPrivileges(1,'Menu'));

Open in new window


What should return is:-

Array
  (
     [Allow Users] => true,
     [Allow Addition] => false,
     [Allow Deletion] => true
  )

So what my question is how do I add the values from the row into the existing array?

It seems to me that $rowPrivileges IS an array already (not an object). So try:
          while ($rowPrivileges = $resPrivileges->fetch_array()) {
            $arrPrivileges = array_merge($arrPrivileges, $rowPrivileges );
          }

$rowPrivileges is an array, which returns:-

array(4) {
  ["userID"]=>
  string(1) "1"
  ["page"]=>
  string(4) "Menu"
  ["setting"]=>
  string(23) "Allow Addition of Users"
  ["value"]=>
  string(4) "true"
}

array(4) {
  ["userID"]=>
  string(1) "1"
  ["page"]=>
  string(4) "Menu"
  ["setting"]=>
  string(24) "Allow Addition of Points"
  ["value"]=>
  string(4) "true"
}

However I want only the 2 elements from the existing arrays so the resulting array should be is:-

array(4) {
  ["Allow Addition of Users"]=>
  string(4) "true"
  ["Allow Addition of Points"]=>
  string(4) "true"
}

So the value is
$rowPrivileges['setting'] = "Allow Addition of Users"
$rowPrivileges['value'] = "true"

So what my code (I belive is doing is):-
array_merge($arrPrivileges,array("Allow Addition of Users"->"true"));

But with variables instead of strings.

OK, that helps.  You need "=>" (not "->") AND you also need to assign the result of array_merge() to $arrPrivileges

while ($rowPrivileges = $resPrivileges->fetch_array()) {
	$arrPrivileges = array_merge($arrPrivileges, array( $rowPrivileges['setting'] => $rowPrivileges['value']) );
}
