I am working on restfull api's for mobile app development. I am returning an php array in json which is like,
"data": {
"Waxing": [
{
"id": "119",
"provider_id": "54",
"provider_service_id": "0",
"category_id": "15",
"date": "09-06-2018",
"time": "08.00 AM,10.00 AM,11.00 AM,12.00 PM,01.00 PM,02.00 PM,03.00 PM,04.00 PM,05.00 PM,06.00 PM,07.00 PM",
"repeat": "D",
"deleted_at": null,
"created_at": "2018-06-09 05:22:47",
"updated_at": "2018-06-09 14:22:04",
"setdate": "09 Jun",
"name": "Waxing"
}
],
"Massage": [
{
"id": "145",
"provider_id": "54",
"provider_service_id": "0",
"category_id": "4",
"date": "14-06-2018",
"time": "08.00 AM,09.00 AM,10.00 AM,11.00 AM,12.00 PM,01.00 PM,02.00 PM,03.00 PM,04.00 PM,05.00 PM,06.00 PM,07.00 PM",
"repeat": "O",
"deleted_at": null,
"created_at": "2018-06-13 14:24:15",
"updated_at": "2018-06-13 14:24:15",
"setdate": "14 Jun",
"name": "Massage"
}
]
},
and creating this output with these line of code:
foreach ($getproviderdatetime as $getproviderdatetimes){
$categorycheck = Category::where('id', '=', $getproviderdatetimes->category_id)->first();
if(count($categorycheck)>0){
$alldata[$categorycheck->name][]=$getproviderdatetimes;
}
}
but now I need data in this format:
"data": {
[
"categoryname": "Waxing",
"services": [
{
"id": "119",
"provider_id": "54",
"provider_service_id": "0",
"category_id": "15",
"date": "09-06-2018",

"repeat": "D",
"deleted_at": null,
"created_at": "2018-06-09 05:22:47",
"updated_at": "2018-06-09 14:22:04",
"setdate": "09 Jun",
"name": "Waxing"
}
]
],
[
"categoryname": "massage",
"services": [
{
"id": "145",
"provider_id": "54",
"provider_service_id": "0",
"category_id": "4",
"date": "14-06-2018",
"time": "08.00 AM,09.00 AM,10.00 AM,11.00 AM,12.00 PM,01.00 PM,02.00 PM,03.00 PM,04.00 PM,05.00 PM,06.00 PM,07.00 PM",

"updated_at": "2018-06-13 14:24:15",
"setdate": "14 Jun",
"name": "Massage"
}
]
]
},
I have array of services and getting category name from database. I am using Laravel framework and returning data in json format. How can I achive this. Need help.
Here's the solution:
foreach ($getproviderdatetime as $getproviderdatetimes){
$categorycheck = Category::where('id', '=', $getproviderdatetimes->category_id)->first();
if(count($categorycheck)>0){
// append new item to all data:
$alldata[] = [
"categoryname" => $categorycheck->name,
"services" => [$getproviderdatetimes],
];
}
}
$testing = []
foreach ($alldata as $key=>$all){
array_push($testing,["categoryname"=>$key,"services"=>$all]);
}
print_r($testing);
Loop again ur $alldata..Bellow is ur solution

I would like to perform the average rating of respective product which stored in the pivot table called "reviews".Below are my existing code.
Product Model:
public function reviews(){
return $this->belongsToMany(User::class,'reviews')->withPivot('comment','rating')->withTimestamps();
}
public function getProductRatingAttribute(){
return $this->reviews()->average('rating');
}
User Model:
public function reviews(){
return $this->belongsToMany(Product::class,'reviews')->withPivot('comment','rating')->withTimestamps();
}
Migration for the reviews
Schema::create('reviews', function (Blueprint $table) {
$table->id();
$table->timestamps();
$table->unsignedBigInteger('user_id');
$table->unsignedBigInteger('product_id');
$table->string('comment')->nullable();
$table->integer('rating');
$table->foreign('user_id')->references('id')->on('users');
$table->foreign('product_id')->references('id')->on('products');
});
I have attempted to use the below to code construct the expected output but it leads N+1 issue because it does not take advantage of the eager loading of the Laravel Eloquent.
$s = Product::with('reviews')->append('product_rating');
As I check telescope, it produces 6 query which can lead performance issue when the data is large.
Expected output:

Appending is performing the query on each record.
Why not perform average on the collection itself?
$s = Product::with('reviews')->get();
$avg = $s->avg('pivot.rating');
Alternatively you can modify the relationship method to include a raw select of the average rating.
CakePHP Rest-API pagination in an array of array. Like, containable model pagination in CakePHP for reducing API load.
Some existing code :
$this->request->data['page'];
$data = $this->Model1->find('all',array(
'contain' => array('Model2'),
'fields' => array(),
'conditions' => array('Model1.status' => 1 )
));
Below API response and I want to paginate in ProductUser array because when lots of product load at one-time app will be hang. It's possible or any other way to reduce data load in CakePHP.

This response consists of list of users and their associated last chat message for currently logged in user. I want to sort this collection according to the latest message first. How can I do that?
Sorting should be based on the chat.created_at field.

UPDATE :
Adding these lines worked as expected. Thanks #JCode
$sorted = $chats->sortByDesc('chat.created_at');
$chats = $sorted->values()->all();
You are looking for the sortBy() method.
This will of course work if your JSON output can be turned into a collection via collect()—in a perfect scenario, your chat messages would be a model in Laravel.

I need to fetch record with child on eager loaded objects
I tried below
$bank_contact = BankDepartment::with(array('OrmBankContact' => function($query) use($bank_id){
$query->where('bank_id', "=", $bank_id)->where('bank_department','>',0);}))
->get();
But no luck.. what is the proper way?
This query should do the job returning only departments with OrmBankContact
BankDepartment::has('OrmBankContact')->get();
See Eloquent docs on querying relations
Model BankDepartment
class BankDepartment extends Eloquent implements UserInterface, RemindableInterface {
public function OrmBankContact(){
return $this->hasMany('OrmBankContact','bank_department','id');
}
}
Model OrmBankContact
class OrmBankContact extends Eloquent implements UserInterface, RemindableInterface {
public function BankDepartment(){
return $this->belongsTo('BankDepartment','bank_department','id');
}
}
In Any controller you can get like this
$OrmBankContact = BankDepartment::with('OrmBankContact')->get();
$OrmBankContact = $OrmBankContact->toArray();
echo '<pre>'; print_r($OrmBankContact); exit;

Use json_decode method to convert it to an std_class or use the 2nd parameter of this method to convert it to an associated array.
Take a look at http://in1.php.net/json_decode
Once you decode it, you can easily access the variables like accessing properties of a class or as an array object if you are converting to an associated array
First you have too decode the JSON using json_decode function, then access using variables.
Do like this..
//Assign your JSON data to this $json variable as shown in the demo.
$arr = json_decode($json,1);
foreach($arr['crop'] as $arr1)
{
foreach($arr1 as $k=>$v)
{
if($arr1['district_id']==1)
{
$avgpr[] = $arr1['price'];
}
}
}
echo $avgprice = array_sum($avgpr)/count($avgpr);
OUTPUT :
40.1
