I can't make use of url with arguments in laravel - laravel

I am working with a rest API, and I cannot do the following query, it throws me an empty array and not the answer that I want to see:
http://localhost/project-test/public/api/contactos/buscar?name=eric&surname=almendras
controller:
public function buscar($name,$surname){
$contacto = Contacto::where('name', $name,'surname',$surname)->get();
return $contacto;
}
route: (api.php)
Route::get('contactos/buscar/{name}/{surname}','ContactosController#buscar');

You define name and surname as url params, but you include it in query string.
To access it you need to use Request class:
public function buscar(Request $request){
$name = $request->input('name');
$surname = $request->input('surname');
$contacto = Contacto::where([
'name' => $name,
'surname' => $surname
])->get();
return $contacto;
}
or change url to:
http://localhost/project-test/public/api/contactos/buscar/eric/almendras

You need to put the 2 conditions in a separate where statement:
$contacto = Contacto::where('name', $name)->where('surname',$surname)->get();

As Daniel says you need to get the parameters from the Request, you then have different options when querying the model.
You can put multiple where clauses in an array, as long as you want all the operators to be =, passed to a single where:
$contacto = Contacto::where([
'name' => $name,
'surname' => $surname
])->get();
or an array of arrays if you want to use different operators:
$contacto = Contacto::where([
['name', '=', $name],
['surname', '<>', $surname]
])->get();
or use multiple where functions
$contacto = Contacto::where('name', $name)
->where('surname', $surname)
->get();
or use Laravel's magic methods:
$contacto = Contacto::whereName($name)
->whereSurname($surname)
->get();

Array on where clause laravel

I have an array of values I want to pass into my where clause when querying a model
How do I achieve this?
I have $categorypro variable getting below array in this format
Array
(
[0] => 4
[1] => 8
[1] => 5
)
Currently I am doing this in controller but not getting proper data some category
Below is my controller code :
function filter_each_video(Request $request){
if(request()->ajax()){
if($request->has('categorypro') && ($request->get('categorypro')!= null)){
$categorypro = $request->get('categorypro');
$item = Item::whereIn('category_id', $categorypro)->get();
}
}
}
If any one have better idea then let me know . Or something wrong in this then give some idea
Generally you would use a 'whereIn' clause:
MyModel::whereIn('attribute', ['value', 'value', 'value'])
->get();
First, you already have the $request in your method, so you don't need to call request(). Always make sure you're validating any data you're using from a request. Second, you can get the query first, then filter it if necessary depending on the post data. Only put your whereIn filter inside the if block.
public function filter_each_video(Request $request)
{
$request->validate([
'categorypro' => 'nullable|array',
'categorypro.*' => 'int'
]);
$query = Item::query();
if ($request->ajax() && $request->categorypro) {
$query->whereIn('category_id',$request->categorypro);
}
$categories = $request->categorypro
? Category::whereIn('id',$request->categorypro)->get()
: null;
$items = $query->get();
return view('myview',compact('items'));
}

How to manipulate a Laravel collection with related models and return a customized instance?

My model relation
return $this->hasMany('App\Models\Opportunity')->with('user');
My Attempt
$project = Project::find(1);
$$opportunities = $project->opportunities
->where('status', "confirmed");
$opportunities->each(function ($opportunity) {
return $opportunity->get('user');
});
Goal
My goal is to return the data in the following structure:
Opportunities:
Opportunity:
Status,
Amount
Currency
Name
Note that the user is a subset of the opportunity itself.
Problem
This returns a 1024 SQL error.
Ideally
It would be ideal if I can return all this information with the query itself.
Call get() method on your query to get its results first:
$oppurtunities = $project->opportunities()
->where('status', "confirmed")
->get();
You have eager loaded the user instance for each opportunity so just call $opportunity->user to return each opportunity's user:
$project = Project::find(1);
$opportunities = $project
->opportunities()
->where('status', "confirmed")
->get();
$filtered = $opportunities->map(function ($opportunity) {
return [
'status' => $opportunity->status,
'amount' => $opportunity->amount_pledged,
'currency' => $opportunity->currency,
'name' => optional($opportunity->user)->full_name
];
})->all();

Laravel eloquent using loop

I am using eloquent query to filter data. My query is like this and it is working perfectly for now.
$users = User::where('username','LIKE','%'.request('username').'%')
->where('first_name','LIKE','%'.request('first_name').'%')
->where('last_name','LIKE','%'.request('last_name').'%')
->where('gender','LIKE','%'.request('gender').'%')
->where('password','LIKE','%'.request('password').'%')
->SimplePaginate(15);
My request data was like this.
However I need to update this query for dynamic fields. There can be different fields. What I did was to send the request in an associative array. So, my request data turned into like this,
What I intend to do is to put all request data in a search array. Then use a loop to run like the above query. How can I do that?
P.S. I checked in the forum and found some similar questions. Some of them are outdated. Others didn't solve my problem.
If I understand you right you can do like this:
$search = request('search', []);
$users = User::query();
foreach($search as $field=>$value)
{
$users = $users->where($field,'LIKE','%'.$value.'%');
}
$users = $users->SimplePaginate(15);
You can try this.
$search = $request->get('search');
User::where(function ($q) use ($search){
foreach ($search as $key=>$value) {
if($value != null ){
$q->where($key, 'like', "%{$value}%");
}
}
})->get();
The where() clause can also accept an array. With that in mind, you could map over your search parameters and convert it to the format you want and then feed it into the query.
For example:
$search = [
'first_name' => 'John',
'last_name' => 'Smith'
];
$filters = collect($search)->map(function($value, $key) {
return [$key, 'LIKE', "%{$value}%"];
})->values()->toArray();
return User::where($filters)->SimplePaginate(15);

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) {
// $extraFields[$eachField] = $query->pluck($eachField)->toArray();
// }
//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
$arrayValues = array_map(
function ($value) use ($arrayKeys) {
return array_combine($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()

Laravel- filter result by several parameters

I want filter a table with several parameters. which I get from a form. it is the index function of the controller where i want to do these things. How can pass these form values to result, how to use laravel collection to apply filter to result. Sorry for a messy question and being silly.
Here is my controller code
$keyword = Input::get('keyword');
$mfs_id = Input::get('mfs_id');
$tps_id = Input::get('tps_id');
$date_start = Input::get('date_start');
$date_end = Input::get('date_end');
//values passed to view
$sales = Sale::paginate(10);
$total = Sale::sums('total_online_sale', 'discount', 'delivery_cost','sales_vat');
$mfs = Mf::lists('mfs_name', 'id');
$tps = Tp::lists('tps_name','id');
// load the view and pass the values
return View::make('sales.index')
->with('sales', $sales)
->with('total',$total)
->with('mfs',$mfs)
->with('tps',$tps);
In view file I am using a form to get $keyword, $mfs_id, $tps_id, $date_start, $date_end
view code
{{ Form::open(array('route' => array('sales.index', array('keyword' => $keyword, 'mfs_id' => $mfs_id, 'tps_id' => $tps_id, 'date_start' => $date_start, 'date_end' => $date_end)))) }}
http://laravel.com/docs/4.2/queries
$users = DB::table('users')->where('start', '>', $date_start)
->where('end', '<=', $date_end)
Or with model:
$users = Users::where('start', '>=', $date_start)
->where('end', '<=', $date_end)
Replace users with your model and add all the parameters in chainging them.
