How to Update Multiple Array Elements in mongodb
(16 answers)
Closed 3 years ago.
I want to update many documents on my db but are nested arrays so I need to use arrayFilters. In the shell works perfect but in my php code never works.
I have tried this way:
$command = new \MongoDB\Driver\Command(
[
'update' => 'students2',
'updates' => [["grades.grade" => ['$gte' => 85]], ['$set' => ["grades.$[elem].mean" => 98 ]], 'arrayFilters' => $filters, 'multi' => true]
]
);
with error: BSON field 'update.updates.grades.grade' is an unknown field
this way:
$db->students2->updateMany([],['$set'=>["grades.$[elem].mean" => 100 ]],['arrayFilters'=> ["elem.grade"=> ['$gte'=>85 ]]]);
with error: "arrayFilters" option has invalid keys for a BSON array
If I execute this command works right but only in one document:
$command = new \MongoDB\Driver\Command(
[
'findAndModify' => 'students2',
'query' => ["grades.grade" => ['$gte' => 85]],
'update' => ['$set' => ["grades.$[elem].mean" => 98 ]],
'upsert' => true,
'returnDocument' => true,
'new' => true,
'arrayFilters' => [['elem.grade'] => ['$gte' => 85]]
]
);
this is my data in mongodb table:
{
"_id" : 1,
"grades" : [
{ "grade" : 80, "mean" : 75, "std" : 6 },
{ "grade" : 85, "mean" : 100, "std" : 4 },
{ "grade" : 85, "mean" : 100, "std" : 6 }
]
}
{
"_id" : 2,
"grades" : [
{ "grade" : 90, "mean" : 100, "std" : 6 },
{ "grade" : 87, "mean" : 100, "std" : 3 },
{ "grade" : 85, "mean" : 100, "std" : 4 }
]
}
What am I doing wrong?
Thanks so much

Try This way
$updateResult = $collection->updateMany(
["inspector" => "J. Clouseau", "Sector" => 4 ],
['$set' => ['Patrolling' => false]]
);
