PHP insert nested arrays into mongoDB - php

Question

I have a function that updates fine with a single dimensional array, but with a multidimensional array (or nested array) it will not update. the document data, the BSONfield (acts as the find key), and the collection are imputed. Any Idea what i am doing wrong?
Public Static function updateDocument($collection, $BSONfield, $document){
$dbcollection = $db->selectCollection($collection);
$sdata = $document[$BSONfield];
$secureInnerDocument = array();
$secureDocument = array();
if($BSONfield == "_id"){
$sdata = new MongoID($sdata);
unset($document["_id"]);
}
$filter = array($BSONfield=>$sdata);
foreach ($document as $k => $v) {
if (is_array($v)) {
foreach ($v as $sk => $sv) {
$secureInnerDocument[$sk] = Security::secureQuery($sv);
}
$secureDocument[$k] = $secureInnerDocument;
}else{
$secureDocument[$k] = Security::secureQuery($v);
}
}
$dbcollection->update($filter,array('$set'=>$secureDocument));
$objid = (string) $secureDocument['_id'];
return $objid;
}

Answer 1

It translates fairly directly:
db.collection.update(
{fieldNameFilter:'filterValue'},
{$set: {'stringFieldName' : 'newValue'}}
);
Translates to:
$collection->update(
array('fieldNameFilter'=>'filterValue'),
array($set => array('stringFieldName'=>$value))
);
Then there are some flags for multi-row updates, etc. which I'm not showing here, but which are in the PHP and Mongo docs.

So after fiddling around with is my solution ended up being kind of janky, I deleted the Document then re-create it. Here is the code in case anyone is looking:
/**
* updates document in the collection.
* This function secures the data
*
* #return object ID
* #param string $collection The name of the collection
* #param string $BSONfield The $BSON Field you want to index by
* #param string $document The document contents as an array
*/
Public Static function updateDocument($collection, $BSONfield, $document){
$db = Database::dbConnect();
$collection = Security::secureQuery($collection);
$BSONfield = Security::secureQuery($BSONfield);
$dbcollection = $db->selectCollection($collection);
if(array_key_exists('_id', $document)){
$document["_id"] = new MongoID($document["_id"]);
}
Database::deleteDocument($collection, $BSONfield, $document);
$objid = Database::createDocument($collection, $document);
return $objid;
}
/**
* Deletes a document in the collection.
* This function secures the data
*
* #return Boolean True - if successfully deleted, False if document not found
* #param string $collection The name of the collection
* #param string $BSONfield The $BSON Field you want to index by
* #param string $document The document contents as an array
*/
Public Static function deleteDocument($collection, $BSONfield, $document){
$db = Database::dbConnect();
$collection = Security::secureQuery($collection);
$BSONfield = Security::secureQuery($BSONfield);
$exists = False;
$dbcollection = $db->selectCollection($collection);
$documentList = $dbcollection->find();
$sdata = $document[$BSONfield];
if($BSONfield == "_id"){
$sdata = new MongoID($sdata);
}
foreach ($documentList as $doc) {
$documentID = $doc[$BSONfield];
if ($documentID == $sdata){
$exists = True;
}
}
if ($exists){
$deleted = True;
$filter = array($BSONfield=>$sdata);
$dbcollection->remove($filter,true);
}else{
$deleted = False;
}
return $deleted;
}
/**
* Inserts document into the collection.
* This function secures the data
*
* #return object ID.
* #param string $collection The name of the collection
* #param string $document The document contents as an array
*/
Public Static function createDocument($collection, $document){
$db = Database::dbConnect();
$collection = Security::secureQuery($collection);
$dbcollection = $db->selectCollection($collection);
$secureDocument = array();
$secureInnerDocument = array();
foreach ($document as $k => $v) {
if (is_array($v)) {
foreach ($v as $sk => $sv) {
$secureInnerDocument[$sk] = Security::secureQuery($sv);
}
$secureDocument[$k] = $secureInnerDocument;
}else{
if ($k == '_id'){
$secureDocument[$k] = $v;
}else{
$secureDocument[$k] = Security::secureQuery($v);
}
}
}
$dbcollection->insert($secureDocument);
$objid = (string) $secureDocument['_id'];
return $objid;
}
and how i am securing all the data from injections:
/**
* Secures string to be inputed into a database.
*
* #return Retuns secure string
* #param String $string String to be secured
*/
Public Static Function secureQuery($string){
$secureString = strtr($string, array(
"'" => "0x27",
"\"" => "0x22",
"\\" => "0x5C",
"<" => "0x3C",
">" => "0x3E",
"=" => "0x3D",
"+" => "0x2B",
"&" => "0x26",
"{" => "0x7B",
"}" => "0x7D",
));
return $secureString;
}
/**
* Un-Secures string to be inputed into a database.
*
* #return Retuns unsecure string
* #param String $string String to be un-secured
*/
Public Static Function unsecureQuery($string){
$secureString = strtr($string, array(
"0x27" => "'",
"0x22" => "\"",
"0x5C" => "\\",
"0x3C" => "<",
"0x3E" => ">",
"0x3D" => "=",
"0x2B" => "+",
"0x26" => "&",
"0x7B" => "{",
"0x7D" => "}",
));
return $secureString;
}
enjoy!

You don't seem to be using the $set operator correctly. As per the MongoDB docs, you need to format your update document like so;
{ $set : { field : value } }
If you're running a $set on nested keys, you need to use dot notation to get to them. For example;
{ $set : { field.nest : value } }
