Laravel SortBy Collection - laravel

I have an eloquent query, 'status' is a custom column created by $collection->filter,
then I have an array with custom fields.
Collection SortByDesc
$collection = $collection->sortByDesc(function($contacts) {
$priority = $this->priority($contacts->status);
$calendar_date = $leads->calendar;
return [
$priority, <-- order it's ok
$calendar_date <-- Here need Calendar by ASC
];
})->values();
Array
public function priority($status)
{
return array_search($status, array_reverse(
[
'closed',
'waiting',
'danger'
]));
}
How can I have an alternate sort by desc and asc?

Filter an array list result from query builder in model in Laravel

I have a query function in my model to get list user and it return an array data to my repository class:
Model.php:
public function getUser()
{
return $this->select("{$this->table}.'*'")
->get();
}
Here is an example for the data:
[
[
"user_id":1,
"fullname":"amdv",
"is_active":0
],
[
"user_id":2,
"fullname":"abc",
"is_active":1
],
[
"user_id":3,
"fullname":"zyz",
"is_active":1
]
]
Now I want to check if is_active = 1, it continue check that user with other condition in other query
In my model, I have another query function with param is user id
Model.php:
public function checkUserAvailable($userId)
{
return $this->select("{$this->table}.'*'")
->join('other_table', 'join-condition')
->where('user_id', $userId)
->get();
}
But this function return data too, I don't know how to check this.
Thank you very much!
$data = [
[
"user_id":1,
"fullname":"amdv",
"is_active":1
],
[
"user_id":2,
"fullname":"abc",
"is_active":1
],
[
"user_id":3,
"fullname":"zyz",
"is_active":1
]
];
$filtered = collect($data)->filter(function($user) {
return User::someMethodYouMentioned($user['user_id']);
});
From what I understand is that you want to check the data from the array returned by the first function and if is_active = 1 then you want to check if the user is available via the second function in your model
//Get the user_id of records where is_active === 1
$available = collect($data)
->reject(fn($user) => $user['is_active'] !== 1)
->pluck('user_id')
->map(fn($id) => User::checkUserAvailable($id));
For this to work the checkUserAvailable needs to be a static function.
However looking at both the functions - question arises why do you need to run multiple database queries to check for user available via the second function.
You can modify the query in the second function to check for is_active
public static function checkUserAvailable()
{
return static::query()
->join('other_table', 'join-condition')
->where('is_active', 1)
->get();
}
Or if you still want to first get a list of all users as array and then check for availability, you could define the checkUserAvailable as a scope on the model
public function scopeCheckUserAvailable($query, $id)
{
$ids = Arr::wrap($id);
return $query->join('other_table', 'join-condition')
->whereIn('user_id', $ids);
}
Then you can get the data from the getUser() function and perform the second check like
//Get the user_id of records where is_active === 1
$checkIds = collect($data)
->reject(fn($user) => $user['is_active'] !== 1)
->pluck('user_id')
->all();
$availableUsers = User::checkAvailableUsers($checkIds)->get();
If you want to filter out the ones that are not active you can use array_filter with a callback:
$filtered = array_filter($array, fn ($i) => $i['is_active']);
If you want to use those values to call a function and then get those results you can use array_map:
$res = array_map([$this, 'checkUserAvailable'], array_column($filtered, 'user_id'));
You can also do this with the Collection methods if you would like:
collect($array)->where('is_active', 1)
->pluck('user_id')
->map([$this, 'checkUserAvailable'])
Though, I am not sure what else you need to be checking besides that is_active is true.

Laravel OrderBy Errors with 5.8 Upgrade

Having trouble with Laravel 5.8 because the orderBy commands stopped working. How would I rewrite these two areas of a controller so it stops throwing an error?
public function index(Request $request)
{
$clients = Client::orderBy('identifier', 'name')->paginate(15);
return view('admin.clients.index')->with('clients', $clients);
}
public function closed()
{
$sortBy = 'name';
$query = Client::onlyTrashed()->orderBy($sortBy, $sortBy == 'created_at' ? 'name' : 'asc')
->orderBy('created_at', 'name');
$projects = $query->get();
return view('admin.clients.index')->with(['clients' => $projects, 'sortBy' => $sortBy]);
}
orderBy(string $column, string $direction = 'asc')
orderBy has two parameters, the second one is direction.
Before version 5.8, if the direction value you passed is not asc, it will automatically set desc as direction value:
$this->{$this->unions ? 'unionOrders' : 'orders'}[] = [
'column' => $column,
'direction' => strtolower($direction) == 'asc' ? 'asc' : 'desc',
];
After Laravel 5.8+, if the direction value is not asc or desc, it will show the error:
if (! in_array($direction, ['asc', 'desc'], true)) {
throw new InvalidArgumentException('Order direction must be "asc" or "desc".');
}
So if you want to order by two column, you can use two orderBy:
$clients = Client::orderBy('identifier')->orderBy('name')->paginate(15);
# Raw SQL:
# select * from clients order by identifier asc, name asc

laravel collection nested query

I'm new with laravel collection . i just want to make this query with collection
DB::select(SELECT id, user_id, created_at,latitude,longitude
FROM coordinates
WHERE created_at IN (
SELECT MAX(created_at)
FROM coordinates
GROUP BY user_id));
according to the document https://laravel.com/docs/6.x/collections
this what i did and it gives me all the data
$this->data['information'] = collect($response->json()['items']);
Edit:
simply i need to produce that query (that i mentioned above) by using Collection.
This is the contents of $response->json()['items']
"#items: array:17 [▼ 0 => array:9 [▼ "id" => 977777779 "platform_id" => "msaeed" "platform_type" => 1 "status" => 1 "longitude" => 1.1 "latitude" => 1.1 "created_by" => "NMF" "created_at" => "2019-10-27T21:00:00Z" "updated_at" => "2019-10-28T07:58:36Z""
any help would be appreciated
Here is the query.
$data = collect($response->json()['items']);
$data = $data->whereIn('created_at', $data->sortByDesc('created_at')
->groupBy('user_id')
->pluck('0.created_at'))
->onlyKeys(['id', 'user_id', 'created_at', 'latitude', 'longitude']);
The equivalent for the subquery:
SELECT MAX(created_at)
FROM coordinates
GROUP BY user_id
is
$data->sortByDesc('created_at') // we use sortByDesc to produce the same result as `MAX`.
->groupBy('user_id')
->pluck('0.created_at') // then to get the max value, just get the first array after grouping.
To achieve the select statement, we need to create a little macro, i've named it onlyKeys:
use Illuminate\Support\Arr;
Collection::macro('onlyKeys', function ($keys) {
return $this->map(function ($value) use ($keys) {
$tmpValue = (array) $value;
if (is_array($tmpValue)) {
$value = Arr::only($tmpValue, $keys);
}
return $value;
});
});
You can register the macro in your AppServiceProvider.php.
PS. Why you need to querying using Collection? Is that data not come from DB?
You want to collect array recursive
Unfortunately laravel does not have this feature:
you can write it on your own.
if you have helpers file you can write this method:
function recursive_collect($array){
foreach ($array as $key => $value) {
if (is_array($value)) {
$value = recursive_collect($value);
$array[$key] = $value;
}
}
return collect($array);
}
Or You can implement macro in your AppServiceProvider:
\Illuminate\Support\Collection::macro('recursive', function () {
return $this->map(function ($value) {
if (is_array($value) || is_object($value)) {
return collect($value)->recursive();
}
return $value;
});
});
Hope this helps you

Pluck with multiple columns?

When i use pluck with multiple columns i get this:
{"Kreis 1 \/ Altstadt":"City","Kreis 2":"Enge","Kreis 3":"Sihifeld","Kreis 4":"Hard","Kreis 5 \/ Industriequartier":"Escher Wyss","Kreis 6":"Oberstrass","Kreis 7":"Witikon","Kreis 8 \/ Reisbach":"Weinegg","Kreis 9":"Altstetten","Kreis 10":"Wipkingen","Kreis 11":"Seebach","Kreis 12 \/ Schwamendingen":"Hirzenbach"
But i need this?
["Rathaus","Hochschulen","Lindenhof","City","Wollishofen","Leimbach","Enge","Alt-Wiedikon","Friesenberg","Sihifeld","Werd","Langstrasse","Hard","Gewerbechule","Escher Wyss","Unterstrass","Oberstrass","Fluntern","Hottingen","Hirslanden","Witikon","Seefeld","M\u00fchlebach","Weinegg","Albisrieden","Altstetten","H\u00f6ngg","Wipkingen","Affoltern","Oerlikon","Seebach","Saatlen","Schwamendingen-Mitte","Hirzenbach"]
Any suggestion how can i do that? This is my method:
public function autocomplete_districts(Request $request)
{
$district = $request->input('query');
// $ass = /DB::table('districts')->select(array('district', 'region'))->get();
// dd($ass);
$data = Districts::whereRaw('LOWER(district) like ?', [strtolower('%'.$district . '%')])->orWhereRaw('LOWER(region) like ?', [strtolower('%'.$district . '%')])->pluck('region','district');
return response()->json($data);
}
You should use select() with get() and then later on modify the object as you need.
So instead of: ->pluck('region','district');
use: ->select('region','district')->get();
pluck() is advised when you need value of one column only.
And as far as possible, you should have your models singular form not plural (Districts) - to follow Laravel nomenclature.
Cos that is how pluck works. Instead try this.
$data = Districts::whereRaw('LOWER(district) like ?', [strtolower('%'.$district . '%')])->orWhereRaw('LOWER(region) like ?', [strtolower('%'.$district . '%')])->select('region', 'district')->get();
$data = collect($data->toArray())->flatten()->all();
In my case I wanted to pluck 2 values from an array of Eloquent models and this worked:
$models->map->only(['state', 'note'])->values()
That's shorter version of
$models->map(fn($model) => $model->only(['state', 'note']))->values()
This is an issue I constantly have faced and has led me to create the following solution that can be used on models or arrays.
There is also support for dot syntax that will create a multidimensional array as required.
Register this macro within the AppServiceProvider (or any provider of your choice):
use Illuminate\Support\Arr;
/**
* Similar to pluck, with the exception that it can 'pluck' more than one column.
* This method can be used on either Eloquent models or arrays.
* #param string|array $cols Set the columns to be selected.
* #return Collection A new collection consisting of only the specified columns.
*/
Collection::macro('pick', function ($cols = ['*']) {
$cols = is_array($cols) ? $cols : func_get_args();
$obj = clone $this;
// Just return the entire collection if the asterisk is found.
if (in_array('*', $cols)) {
return $this;
}
return $obj->transform(function ($value) use ($cols) {
$ret = [];
foreach ($cols as $col) {
// This will enable us to treat the column as a if it is a
// database query in order to rename our column.
$name = $col;
if (preg_match('/(.*) as (.*)/i', $col, $matches)) {
$col = $matches[1];
$name = $matches[2];
}
// If we use the asterisk then it will assign that as a key,
// but that is almost certainly **not** what the user
// intends to do.
$name = str_replace('.*.', '.', $name);
// We do it this way so that we can utilise the dot notation
// to set and get the data.
Arr::set($ret, $name, data_get($value, $col));
}
return $ret;
});
});
This can then be used in the following way:
$a = collect([
['first' => 1, 'second' => 2, 'third' => 3],
['first' => 1, 'second' => 2, 'third' => 3]
]);
$b = $a->pick('first', 'third'); // returns [['first' => 1, 'third' => 3], ['first' => 1, 'third' => 3]]
Or additionally, on any models you may have:
$users = User::all();
$new = $users->pick('name', 'username', 'email');
// Might return something like:
// [
// ['name' => 'John Doe', 'username' => 'john', 'email' => 'john#email.com'],
// ['name' => 'Jane Doe', 'username' => 'jane', 'email' => 'jane#email.com'],
// ['name' => 'Joe Bloggs', 'username' => 'joe', 'email' => 'joe#email.com'],
// ]
It is also possible to reference any relationship too using the dot notation, as well as using the as [other name] syntax:
$users = User::all();
$new = $users->pick('name as fullname', 'email', 'posts.comments');
// Might return something like:
// [
// ['fullname' => 'John Doe', 'email' => 'john#email.com', 'posts' => [...]],
// ['fullname' => 'Jane Doe', 'email' => 'jane#email.com', 'posts' => [...]],
// ['fullname' => 'Joe Bloggs', 'email' => 'joe#email.com', 'posts' => [...]],
// ]
My solution in LARAVEL 5.6:
Hi, I've just had the same problem, where I needed 2 columns combined in 1 select list.
My DB has 2 columns for Users: first_name and last_name.
I need a select box, with the users full name visible and the id as value.
This is how I fixed it, using the pluck() method:
In the User model I created a full name accessor function:
public function getNameAttribute() {
return ucwords($this->last_name . ' ' . $this->first_name);
}
After that, to fill the select list with the full name & corresponding database id as value, I used this code in my controller that returns the view (without showing users that are archived, but you can change the begin of the query if you like, most important are get() and pluck() functions:
$users = User::whereNull('archived_at')
->orderBy('last_name')
->get(['id','first_name','last_name'])
->pluck('name','id');
return view('your.view', compact('users'));
Now you can use the $users in your select list!
So first, you GET all the values from DB that you will need,
after that you can use any accessor attribute defined for use in your PLUCK method,
as long as all columns needed for the accessor are in the GET ;-)
As far as now Laravel didn't provide such macro to pick specific columns, but anyway Laravel is out of the box and lets us customize almost everything.
Tested in Laravel 8.x
in AppServiceProvider.php
use Illuminate\Support\Collection;
// Put this inside boot() function
Collection::macro('pick', function (... $columns) {
return $this->map(function ($item, $key) use ($columns) {
$data = [];
foreach ($columns as $column) {
$data[$column] = $item[$column] ?? null;
}
return $data;
});
});
Usage
$users = App\Models\User::all();
$users->pick('id','name');
// Returns: [['id' => 1, 'name' => 'user_one'],['id' => 2, 'name' => 'user_two']]
Important notes:
Do not use this macro for a really HUGE collection (You better do it on Eloquent
select or MySQL query select)
Laravel: To pluck multi-columns in the separate arrays use the following code.
$Ads=Ads::where('status',1);
$Ads=$Ads->where('created_at','>',Carbon::now()->subDays(30));
$activeAdsIds=$Ads->pluck('id'); // array of ads ids
$UserId=$Ads->pluck('user_id'); // array of users ids
I have created the model scope

public function scopePluckMultiple( $query, string $keyColumn, array $extraFields):\Illuminate\Support\Collection
{
//pluck all the id based on the query builder instance class
$keyColumnPluck = $query->pluck( $keyColumn)->toArray();
//anonymous callback method to iterate over the each fileds of table
$callBcakMethod = function ($eachValue) use ($query)
{
$eachQuery[$eachValue] = $query->pluck( $eachValue)->toArray();
return $eachQuery;
};
//now we are collapsing the array single time to get the propered array
$extraFields = \Illuminate\Support\Arr::collapse( array_map($callBcakMethod, $extraFields));
// //iterating Through All Other Fields and Plucking it each Time
// foreach ((array)$extraFields as $eachField) {

//now we are done with plucking the Required Columns
//we need to map all the values to each key
//get all the keys of extra fields and sets as array key or index
$arrayKeys = array_keys($extraFields);
//get all the extra fields array and mapping it to each key
$arrayValues = array_map(

return array_combine($arrayKeys, $value);
},
call_user_func_array('array_map', array_merge(
array(function () {
return func_get_args();
}),
$extraFields
))
);
//now we are done with the array now Convert it to Collection
return collect( array_combine( $keyColumnPluck, $arrayValues));
}
So now the testing part
BASIC EXAMPLE
$basicPluck = Model::pluckMultiple('primaryKeyFiles',['fieldOne', 'FieldTwo']);
ADVANCED EXAMPLE
$advancedPlcuk = Model::whereBetween('column',[10,43])
->orWhere('columnName','LIKE', '%whildCard%')
->Where( 'columnName', 'NOT LIKE', '%whildCard%')
->pluckMultiple('primaryKeyFiles',['fieldOne', 'FieldTwo']);
But it returns the \Illuminate\Support\Collection, so if you need to convert to array
$toArrayColl = $advancedPluck->toArray();
if you need to convert to json
$toJsonColl = $advancedPluck->toJson();
To answer the specific question of "how to return multiple columns using (something like) pluck" we have to remember that Pluck is a Collection member function. So if we're sticking to the question being asked we should stick with a Collection based answer (you may find it more beneficial to develop a model-based solution, but that doesn't help solve the question as posed).
The Collection class offers the "map" member function which can solve the posed question:
$data = Districts::whereRaw('LOWER(district) like ?', [strtolower('%'.$district . '%')])->orWhereRaw('LOWER(region) like ?', [strtolower('%'.$district . '%')])
->map(function ($item, $key, $columns=['region','district']) {
$itemArray = [];
foreach($columns as $column){
$itemArray[$column] = $item->$column;
}
return ($itemArray);
});
dd($data);
This should give you a collection where each element is a 2 element array indexed by 'region' and 'district'.
Laravel 8.x, try to use mapWithKeys method instead of pluck, for example:
$collection->mapWithKeys(function ($item, $key) {
return [$key => $item['firstkey'] . ' ' . $item['secondkey']];
});
Expanding on #Robby_Alvian_Jaya_Mulia from above who gave me the idea. I needed it to also work on a relationship. This is just for a single relationship, but it would probably be easy to nest it more.
This needs to be put into AppServiceProvider.php
use Illuminate\Support\Collection;
// Put this inside boot() function
Collection::macro('pick', function (... $columns) {
return $this->map(function ($item, $key) use ($columns) {
$data = [];
foreach ($columns as $column) {
$collection_pieces = explode('.', $column);
if (count($collection_pieces) == 2) {
$data[$collection_pieces[1]] = $item->{$collection_pieces[0]}->{$collection_pieces[1]} ?? null;
} else {
$data[$column] = $item[$column] ?? null;
}
}
return $data;
});
});
Usage:
$users = App\Models\User::has('role')->with('role')->all();
$users->pick('id','role.name');
// Returns: [['id' => 1, 'name' => 'role_name_one'],['id' => 2, 'name' => 'role_name_two']]
Hope this is helpful to someone. Sorry I didn't add this to under #Robby's answer. I didn't have enough reputation.
Pluck returned only the value of the two columns which wasnt ideal for me, what worked for me was this :
$collection->map->only(['key1', 'key2'])->values()

UpdateExistingPivot for multiple ids

In order to update single record in pivot table I use updateExistingPivot method. However it takes $id as the first argument. For example:
$step->contacts()->updateExistingPivot($id, [
'completed' => true,
'run_at' => \Carbon\Carbon::now()->toDateTimeString()
]);
But how can I update multiple existing rows in pivot table at once?
There's an allRelatedIds() method in the BelongsToMany relation that you can access, which will return a Collection of the related model's ids that appear in the pivot table against the initial model.
Then a foreach will do the job:
$ids = $step->contacts()->allRelatedIds();
foreach ($ids as $id){
$step->contacts()->updateExistingPivot($id, ['completed' => true]);
}
You can update only by using a looping statement as there updateExistingPivot function only accept one dimensional params, See the core function for laravel 5.3.
File: yoursite\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Relations\BelongsToMany.php
Function: updateExistingPivot
public function updateExistingPivot($id, array $attributes, $touch = true)
{
if (in_array($this->updatedAt(), $this->pivotColumns)) {
$attributes = $this->setTimestampsOnAttach($attributes, true);
}
$updated = $this->newPivotStatementForId($id)->update($attributes);
if ($touch) {
$this->touchIfTouching();
}
return $updated;
}
So, You should follow the simple process:
$step = Step::find($stepId);
foreach(yourDataList as $youData){
$step->contacts()->updateExistingPivot($youData->contract_id, [
'completed' => true,
'run_at' => \Carbon\Carbon::now()->toDateTimeString()
]);
}
