How can I upsert (update if not added) two fields at the same time?
It worked for a single field, but it doesn't work for two anymore.
Am I doing something wrong?:
$db->url->update(
array("url" => $linkurlcache),
array('$set' => array('url' => $linkurlcache, 'pos' => $rand_num)),
array("upsert" => true),
array("multi" => true)
);
I really hate having to answer my own question. I would have deleted it but I couldn't find a solution on any website.
Anyhow, the array("multi" => true) made a lot of sense considering we are calling the update function, but it's wrong.
The correct solution is without it!
Just:
$db->url->update(
array("field1" => $field1),
array('$set' => array('field1' => $field1, 'field2' => $field2)),
array("upsert" => true)
);
Because upsert actually makes an insert (if the query doesn't match).

The following code should work. I could have missed something, but right now I have it as 2 separate update statements and have decided to ask here why this line isn't working.
$this->db->settings->update(array('_id' => $mongoID),
array(
'$set' => array('about' => $about),
'$set' => array('avatar' => $avatar)
)
);
Did I miss something when reading guides or is it only possible to do with separate update statements?
The third argument to MongoCollection::update is an array of options for the update operation.
$this->db->settings->update(
array('_id' => $mongoID),
array('$set' => array('about' => $about, 'avatar' => $avatar))
);
I am having a problem in updating values i get from web service ..
$collection = $modb->$table;
$collection->update(array("id" => (int)$row['id']),
array('$set' => array(
"user_id" => (int)$post_data_array['user_id'],
"story" => (int)$post_data_array['story'],
"surprize_sub1" => (int)$post_data_array['surprize_sub1'],
"surprize_sub2" => (int)$post_data_array['surprize_sub2'],
"surprize_sub3" => (int)$post_data_array['surprize_sub3'],
"exr_solve" => (int)$post_data_array['exr_solve'],
"exr_assessmnt" => (int)$post_data_array['exr_assessmnt'],
"exr_refresh" => (int)$post_data_array['exr_refresh'],
"sound_control" => (int)$post_data_array['sound_control'],
"clock_control" => (int)$post_data_array['clock_control'],
"switch_user" => (int)$post_data_array['switch_user'],
"exr_print" => (int)$post_data_array['exr_print'],
"write_on_wall" => (int)$post_data_array['write_on_wall'],
"switch_letter" => (int)$post_data_array['switch_letter'],
"view_controls" => (int)$post_data_array['view_controls'],
)));
I get these values from end users.. i want the specific field sent to be updated without loosing all the rest of data ..
in this code only sent data is set while removing the rest .. i want to change only sent ones by keeping the rest as they are, please advice
you need to use updateOne instead of update .
updateOne
Use the MongoDB\Collection::updateOne() method to update a single document matching a filter.
$collection = $modb->$table;
$collection->updateOne(array("id" => (int)$row['id']),
array('$set' => array(
// .... array elements
)));
First of all this is my code:
Log::create([
'action' => $event->changes[0], //<- This is my problem
'object_id' => $event->id,
'object_type' => "Account",
'ip_address' => Request::ip(),
'user' => ucfirst(Auth::user()->name),
'time' => Carbon::now()->format('H:i:s'),
'date' => Carbon::now()->format('Y-m-d')
]);
$event->changes is an array which contains many items but i only know how to get 1 specific item at a time using the index [0] or [1] etc.
How do I get all the values to display instead of 1 at a time? Obviously I don't want to create a new log for each single action but I cant figure out how to do this.
As always any help is appreciated thank you.
You need to serialize the $event->changes if you want it within one log entry.
It actually depends on the structure of changes array, but it seems to be an array of strings, so you may for example use the implode(', ', $changes), so the snippet would look the following:
Log::create([
'action' => implode(', ', $event->changes), //<- This is my problem
'object_id' => $event->id,
'object_type' => "Account",
'ip_address' => Request::ip(),
'user' => ucfirst(Auth::user()->name),
'time' => Carbon::now()->format('H:i:s'),
'date' => Carbon::now()->format('Y-m-d')
]);

Following this question I gather that upsert: false and multi: true fields need to be set for this to work.
However, when I try to code this in PHP, I have a problem:
$conn = new Mongo("mongodb://foo:bar#localhost:27017");
$db = $conn->selectDB("someDB");
$data = array('$rename' => array(
'nmae' => 'name'
));
$db->command(array(
'findAndModify' => 'foo',
'update' => $data,
'upsert' => 'false',
'multi' => 'true'
));
After running this script, only the first document with the nmae typo is changed to name; the rest still say nmae. The same as if I had run it without the upsert and multi options.
I also tried this:
$data = array('$rename' => array(
'nmae' => 'name'
),
'upsert' => 'false',
'multi' => 'true'
);
$db->command(array(
'findAndModify' => 'foo',
'update' => $data
));
But that does the same thing.
Any way to get this working?
The findAndModify query doesn't have a "multi" option:

What you probably want to use is update instead:
