I have a database table with the following columns:
columnindex | type | id
1 1 1
2 2 1
3 3 1
I have a input array:
$arr = [1 => 2, 2 => 5, 3 => 6,...]
As result I need this:
columnindex | type | id
1 2 1
2 5 1
3 6 1
How to use update bulk in this case?
I tried this but it is not optimized:
$arr = [1 => 2, 2 => 5, 3 => 6];
foreach($arr as $columnindex => $type) {
SessionPrepared::where("id", 1)->where("columnindex", $columnindex)->update(["type" => $type]);
}
You are looking for the upsert method (https://laravel.com/docs/9.x/eloquent#upserts).
Example:
SessionPrepared::upsert([
['id' => 1, 'columnindex' => 1, 'type' => 'value'],
['id' => 2, 'columnindex' => 2, 'type' => 'value'],
['id' => 3, 'columnindex' => 3, 'type' => 'value'],
], ['id', 'columnindex'], ['type']);
Results in it bulk updating the column type for the provider identifiers id & columnindex

hello i am facing problem in where condition laravel.
i have two array
$a = [▼
0 => 2
1 => 9
2 => 39
3 => 174
4 => 190
];
$b = [▼
0 => 2
1 => 9
2 => 39
3 => 174
4 => 190
5 => 0
];
**array values is ids. i tried array_values($a) && array_values($b)
i want ids like this but not get same response.**
[ 2 ,9 ,39 ,174 ,190] && [ 2 ,9 ,39 ,174 ,190 , 0 ]
trying to get data from query like
$classrooms = Classroom::where('teacher_id', $teacherId)
->where('school_curriculum_id', [$b])
->where('hybrid_curriculum', [$b])->get();
but got null . something wrong in where condition.
please help me to solve this.
protected $fillable = [
'id', 'school_id', 'grade_id', 'teacher_id', 'school_curriculum_id', 'name', 'deleted', 'deleted_date', 'archived', 'is_hybrid', 'hybrid_curriculum', 'hybrid_grade', 'enable_auto_submit_assessment', 'timeline_type', 'timeline_modified', 'group_test_by', 'created', 'modified', 'enable_auto_lockout_unit',
];
Can you try this:
$classrooms = Classroom::where('teacher_id', $teacherId)
->whereIn('school_curriculum_id', $b)
->whereIn('hybrid_curriculum', $b)->get();
I have A Table
id Primary bigint(20)UNSIGNED AUTO_INCREMENT,
school_id bigint(20)UNSIGNED Foreign Key,
teacher_id bigint(20)UNSIGNED Foreign Key,
course_id bigint(20)UNSIGNED Foreign Key,
klass_id bigint(20)UNSIGNED Foreign Key,
I Want to add Some data To this table, My data is given below.
{
"school_id":5,
"teacher_id":2,
"course_id":[1,2,3],
"klass_id":[7,8,3],
}
How Can I store this data Like Below
--id|school_id|teacher_id|course_id|klass_id
----------------------------------------------
1 | 5 | 2 | 1 | 7
2 | 5 | 2 | 2 | 8
3 | 5 | 2 | 3 | 3
If the input is always gonna be in the format of
"school_id" will have 1 value,
"teacher_id" will have 1 value,
"course_id" will have x values,
"klass_id" will have x values,
Then you can do something like:
$mapped = [];
for($i=0; $i<count($data['course_id']); $i++) {
$mapped[] = [
"school_id" => $data['school_id'],
"teacher_id" => $data['teacher_id'],
"course_id" => $data['course_id'][$i],
"klass_id" => $data['klass_id'][$i]
]
}
Then you can call any eloquent or DB function to insert like:
Model::insertMany($mapped);
P.S: There must be a better way of doing it that I don't know of. :(
Are you trying to save this data manually? if yes, create database SEED and add these data in array format like below: create a class with command php artisan make:seeder CreateSeedTableName and add this below code
$arr = [
[
"school_id" => 5,
"teacher_id" => 2,
"course_id" => 1,
"klass_id" => 7
],
[
"school_id" => 5,
"teacher_id" => 2,
"course_id" => 2,
"klass_id" => 8
],
[
"school_id" => 5,
"teacher_id" => 2,
"course_id" => 3,
"klass_id" => 3
]
];
TableName::insert($arr);
or you can use loop if you have same format data in request.
$count = count($data['course_id']); //get course count
$schoolId = $data['school_id']; //get school id
$teacherId = $data['teacher_id']; //get teacher id
for ($i = 0; $i < $count; $i++) {
TableName::create([
'school_id' => $schoolId,
"teacher_id" => $teacherId,
"course_id" => $data['course_id'][$i],
"klass_id" => $data['klass_id'][$i],
]);
}
I got this array:
What I want to do next is to make a collection from the array and I write:
$variant_images = collect($p->images);
but I got the error:
"Undefined index: images"
What's bad in my code and how to solve it?
Assuming $p is array like this
$p = [
'images' => [
1, 2, 3, 4
]
];
you can write
$collection = collect($p);
// access the images
var_dump($collection->get('images'));
and the output would be
array:4 [▼
0 => 1
1 => 2
2 => 3
3 => 4
]
This is my array data from
$users = [1, 2, 3, 4];
$bidder = [3, 6, 7, 2];
And i want to sort like this
users_id | bidder
---------- ** ----------
4 | 2
1 | 3
2 | 6
3 | 7
and In Controller,using Collections I sort in this way
$users=$request->user_id;
$bidder=$request->bidder_rate;
$data = collect($users)->map(function ($user, $key) use ($bidder) {
return [
'user_id' => $user,
'bidder' => $bidder[$key]
];
})->sortBy('bidder');
Now when i do dd($data).It worked
1 => array:2 [▼
"user_id" => "2"
"bidder" => "10"
]
0 => array:2 [▼
"user_id" => "1"
"bidder" => "12"
]
2 => array:2 [▼
"user_id" => "4"
"bidder" => "15"
]
But now i want to save all user_id and bidder sorted data in respective field(user_id & bidder) in
array form.So how can i store them
$auction=new Auction();
$auction->name=$data['auction_name'];
$auction->user_id=$data['user_id']; //I think i cannot do like this
$auction->bidder=$data['bidder'];
Try this
$auction=new Auction();
$auction->name=collect($data)->pluck("user_id");
$auction->user_id=collect($data)->pluck("bidder");
$auction->bidder=$data['bidder'];
hi im using Maatwebsite with laravel everything working so good so far ..
but i want to update excel like this ..

3 2020-03-03 -40
what i want thats the sum of the amount with number 1 sould return 0 or end the import
number date amount
1 2020-01-01 10
1 2020-01-01 -5
1 2020-01-01 -5
how can i check this (10 + -5 + -5 == 0) or fail
and for 2 and 3 ect ..
thanks a lot
I explained all the steps in comments but I will explain here as well.
When you loop through each row, you first need to grab all the rows where number field is 1, 2 or 3, what ever the number is currently in the iteration.
In this case, the first loop results will be:
number date amount
1 2020-01-01 10
1 2020-01-01 -5
1 2020-01-01 -5
Then you sum (add up) the values from the amount column.
In this case, it will sum like this:
10
-5
-5
-----
0
If the answer is not 0, take the current sheet ($sheet) and return what you currently have, to be exported.
