从PHP调用

Question

存储JavaScript函数MongoDB中我已经存储在db.system.js

function SomeFunc(o) { 
    x = db.Collection; 
    while(1) { 
     var c = x.find({},{_id:1}).sort({_id:-1}).limit(1); 
     var i = c.hasNext() ? c.next()._id + 1 : 1; 
     o._id = i; 
     x.insert(o); 
     var err = db.getLastErrorObj(); 
     if(err && err.code) { 
      if(err.code == 11000 /* dup key */) 
       continue; 
      else 
       print("unexpected error inserting data: " + tojson(err)); 
     } 
     break; 
    } 
} 

在PHP

print_r(
    $db->execute("SumeFunc(o)", array("name" => "test")) 
); 

错误

Array 
(
    [errno] => -3 
    [errmsg] => invoke failed: JS Error: ReferenceError: o is not defined nofile_a:0 
    [ok] => 0 
) 

Answer 1

$db->execute(
    new MongoCode('SomeFunc(o)', array(
     'o' => array('name' => 'test') 
    )) 
);
