PHP Mongodb not updating array -


i not sure why getting error

fatal error: call member function update() on non-object in /home/xxxxxxxxxxxxxxxxx/classes/core.php on line 22

on page have this

public function updatemongo($from,$data)     {         $this->db = $m->exchange_rates;         $collection = $this->db->exchangedb;         $collection->update(array("from" => $from), $data);     }

this how calling function

foreach ($currencies $to)  {     if($from != $to)     {          $url = 'http://finance.yahoo.com/d/quotes.csv?f=l1d1t1&s='.$from.$to.'=x';         $handle = fopen($url, 'r');          if ($handle) {             $result = fgetcsv($handle);                 fclose($handle);         }          $newdata = array('$set' => array("exchangehistory.{$result[1]}.{$result[2]}" => array("to" => $to, "rate" => $result[0], "updated" => $result[2])));         $fetch->updatemongo($from,$newdata);          $newdata = array('$set' => array("currentexchange" => array("to" => $to, "rate" => $result[0], "updated" => $result[2])));         $fetch->updatemongo($from,$newdata);       }  }

and yes file needing access has require_once("core.php");

please let me know why not working.

the updatemongo() function doesn't have access $m variable. please pass function this:

$fetch->updatemongo($m, $from, $newdata);

and change function definition to:

public function updatemongo($m, $from, $data) {

alternatively, can set m property of object connection after you've created it. example with:

public function __construct) {     $this->m = new mongo(); } ... public function updatemongo($from, $data) {     $this->db = $this->m->exchange_rates;     $collection = $this->db->exchangedb;     $collection->update(array("from" => $from), $data); }

or perhaps can use $this->exchange_rates above... in case, you're not making $m available function.
