I'm struggling to remove item from recursive array if parent id don't match. All I want to display separate tree for each tree number. I didn't find any solution with SQL so now I am retrieving top nodes of that tree number and removing array those items don't have that top node ids. I already have tree structure, below I'm providing the structure of array.
{
"196": {
"id": "196",
"username": "test1",
"parent_id": null,
"children": [
{
"id": "197",
"parent_id": "196",
"flower_id": null,
"username": "test1",
"children": []
},
{
"id": "198",
"parent_id": "196",
"flower_id": "1690587",
"username": "test3",
"children": [
{
"id": "213",
"parent_id": "198",
"flower_id": "5197062",
"username": "test33",
"children": []
}
]
},
{
"id": "199",
"parent_id": "196",
"flower_id": "1690587",
"username": "test2",
"children": [
{
"id": "205",
"parent_id": "199",
"flower_id": null,
"username": null,
"children": [
{
"id": "207",
"parent_id": "205",
"flower_id": null,
"username": null,
"children": []
}
]
},
{
"id": "212",
"parent_id": "199",
"flower_id": "6794158",
"username": "gunu",
"children": []
}
]
}
]
}
}
Here is what I'm doing doing
function recursive_unset(&$array, $parentIds = array()) {
foreach ($array as $key => &$value) {
if(!in_array($value['parent_id'], $parentIds)) {
unset($array[$key]);
}
if (is_array($value['children'])) {
$this->recursive_unset($value, $parentIds);
}
}
}
This is how I'm calling this function $data = $this->recursive_unset($array, [198,199]);
Any help is appreciated.
Thanks in advance.
I have tables, users, profiles, contacts. 1 user has 1 profile, 1 profile has many contacts, I want to get profile with filtered contact and selected column (I don't want get all column). I success with coding below
UserController.php
$profile = $user->with(['profile.emails', 'profile.phones'])->first();
User.php
public function profile()
{
return $this->hasOne(Profile::class);
}
Profile.php
public function emails()
{
return $this->hasMany(Contact::class)
->where('type', 'email');
}
public function phones()
{
return $this->hasMany(Contact::class)
->where('type', 'phone');
}
result data like this
{
"username": "user",
"email": "user#mail.com",
"profile": {
"first_name": "Alex",
"last_name": "Ariana",
"emails": [
{
"id": 1,
"profile_id": 1,
"type": "email",
"prefix": "Personal",
"value": "alex#mail.com",
"is_primary": 0,
},
{
"id": 2,
"profile_id": 1,
"type": "email",
"prefix": "Business",
"value": "business#mail.com",
"is_primary": 1,
}
],
"phones": [
{
"id": 3,
"profile_id": 1,
"type": "phone",
"prefix": "45",
"value": "564637345345",
"is_primary": 1,
}
]
}
}
but then I add select on the relation like this
public function emails()
{
return $this->hasMany(Contact::class)
->select([DB::raw('IFNULL(prefix, "Email") AS type'), 'value AS url', 'is_primary'])
->where('type', 'email');
}
public function phones()
{
return $this->hasMany(Contact::class)
->select(['prefix', 'value AS number', 'is_primary'])
->where('type', 'phone');
}
then I got empty contact data like this
{
"id": 1,
"username": "user",
"email": "user#mail.com",
"profile": {
"first_name": "Alex",
"last_name": "Ariana",
"emails": [ ],
"phones": [ ]
}
}
Why this is happen?, if I access from user via hasManyThrough it works, but when I use hasMany, it result empty.
I have categories with id, parent_id, slug , pivot table category_language which columns are id,category_id,language_id,value
As you can see I can translate parent category, but can't send desired $lang_id to children translations, so each children having all translations
here is what I get:
{
"id": 1,
"parent_id": 0,
"slug": "personal-computers",
"created_at": "2019-12-27 15:05:31",
"updated_at": "2019-12-27 15:05:31",
"children": [
{
"id": 3,
"parent_id": 1,
"slug": "accessories-for-pc",
"created_at": "2019-12-27 15:05:32",
"updated_at": "2019-12-27 15:05:32",
"translations": [
{
"id": 1,
"code": "en",
"name": "English",
"pivot": {
"category_id": 3,
"language_id": 1,
"value": "Acc for PC",
"id": 7
}
},
{
"id": 2,
"code": "ru",
"name": "Русский",
"pivot": {
"category_id": 3,
"language_id": 2,
"value": "Аксессуары для ноутбуков и ПК",
"id": 8
}
},
{
"id": 3,
"code": "ro",
"name": "Romana",
"pivot": {
"category_id": 3,
"language_id": 3,
"value": "aksessuari-dlya-noutbukov-i-pk-ro",
"id": 9
}
}
]
}
],
"translations": [
{
"id": 1,
"code": "en",
"name": "English",
"pivot": {
"category_id": 1,
"language_id": 1,
"value": "PC",
"id": 1
}
}
]
}
Controller:
return Category::with('children')
->with(array('translations'=>function($query) use ($lang_id){
$query->where('language_id',$lang_id);
}))
->where('parent_id',0)->first();
Model
class Category extends Model
{ ..
public function translations()
{
return $this->belongsToMany('App\Models\Translation','category_language', 'category_id' ,'language_id' )->withPivot('value','id');
}
public function children()
{
return $this->hasMany( 'App\Models\Category' , 'parent_id' , 'id' )->with('translations');
}
}
you can add condition in children method
public function children()
{
return $this->hasMany( 'App\Models\Category' , 'parent_id' , 'id' )->with('translations')->where('language_id', 1);
}
Dry7 answer was close to the one I've implemented later, so I upvoted him.
Finally in model I've added: ...->where('language_id',helper_SetCorrectLangIdForQuery());
and function helper_SetCorrectLangIdForQuery is using global helper of Laravel request()->lang . If lang=enz, than it takes default language from another helper.
i'm new in laravel and php and now i wanna create a rest api
I have this query:
$questions = Question::with(
array('picture' => function($query){
$query>select('question_id','picture_name')>pluck('picture_name')>all();
},
'user'=>function($query){
$query->select('id','image','name');
}))->get()->toArray();
my query return this json:
{
"questions:": [
{
"id": 1,
"title": "23",
"caption": "last",
"address": "lsdbabfd",
"picture": [
{
"question_id": 1,
"picture_name": "1527484678.jpg"
},
{
"question_id": 1,
"picture_name": "1527485120.jpg"
}
],
"user": {
"id": 1,
"image": "defaultPicture",
"name": "alex"
}
}
]
}
but i want this json:
{
"questions:": [
{
"id": 1,
"title": "23",
"caption": "last",
"address": "lsdbabfd",
"picture": [
"1527484678.jpg",
"1527485120.jpg"
],
"user": {
"id": 1,
"image": "defaultPicture",
"name": "alex"
}
}
]
}
how can i do that?
i already tried to do that with Laravel pluck method and Eloquent Mutators
you can add attribute method
class Question extends Model
{
...
protected $appends = ['pictures'];
public function getPicturesAttribute()
{
return $this->pictures->pluck('picture_id');
}
}
I've gone through a few examples and documentations and kind find a solution update a nested object in the this result set.
I can add one (if one does not exist)
I can append to it (if one does exist)
Can't figure out how to delete a selected entry.
Is there a method I can use (using the php client) to add an entry if it does not exist / update an entry if it does exist / delete the second entry.
I'm inheriting this problem and am new to Elastic search.
Thanks.

Do you want to do all three in the same operation?
Deleting the second nested object is achieved through a script which removes the second element:
PUT /products
{
"mappings": {
"categories": {
"properties": {
"parent": {
"type": "nested",
"properties": {
"name": { "type": "string" },
"description": { "type": "string" },
"id": { "type": "string", "index": "not_analyzed" },
"slug": { "type": "string" }
}
}
}
}
}
}
PUT /products/categories/1
{
"name": "Primary",
"description": "Primary Category",
"slug": "Primary",
"created": "2014-12-16 00:25:22",
"parent": [
{
"name": "First One",
"description": "Test",
"id": "ae74ea4e2e865ed3fd60c18a06e69c65",
"slug": "first-one"
},
{
"name": "Second One",
"description": "Testing Again",
"id": "c8dbe5143c8dfd6957fa33e6cea7a0a8",
"slug": "second-one"
}
]
}
POST /products/categories/1/_update
{
"script" : "ctx._source.parent.remove(1)",
"lang": "groovy"
}
GET /products/categories/1
So in PHP code (using the official PHP client), the update would look like:
$params = [
'index' => 'products',
'type' => 'categories',
'id' => 1,
'body' => [
'script' => 'ctx._source.parent.remove(1)',
'lang' => 'groovy'
]
];
$result = $client->update($params);
