I am trying to get data for each id using foreach. But when code run it get only data for 1 ID.. Following is the code
$buffalidforavgmilk = Buffalodata::groupBy('buffaloID')->get('buffaloID')- >pluck('buffaloID')->toArray();
foreach ($buffalidforavgmilk as $id) {
$milkperid = Buffalomilkrecord::where('buffaloID', $id)->pluck('buffaloID')->toArray();
dd([$buffalidforavgmilk,$milkperid]);
}
Output
array:2 [▼
0 => array:4 [▼
0 => "Buffalo-01"
1 => "Buffalo-02"
2 => "Buffalo-03"
3 => "Buffalo-04"
]
1 => array:5 [▼
0 => "Buffalo-01"
1 => "Buffalo-01"
2 => "Buffalo-01"
3 => "Buffalo-01"
4 => "Buffalo-01"
]
]
Here Loop giving only 1 ID where as required array for all 4 ID
( for Test, i try to get only buffaloID)
Thanks in Advance
dd interrupts execution. If you wanted to dump every result and then stop execution, you should have used dump instead
foreach ($buffalidforavgmilk as $id) {
$milkperid = Buffalomilkrecord::where('buffaloID', $id)->pluck('buffaloID')->toArray();
dump([$buffalidforavgmilk,$milkperid]);
}
dd('Done');
This is not ideal though. You are making a query in each iteration of the loop.
One way you could remove the foreach is to change your query to use whereIn.
$buffalidforavgmilk = Buffalodata::groupBy('buffaloID')->pluck('buffaloID')->toArray();
$milkperids = Buffalomilkrecord::whereIn('buffaloID', $buffalidforavgmilk)->pluck('buffaloID')->toArray();

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 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'];
This the data when user submit the form :
POST Data
_token
"JNDt8WC6kVbvrSdFTKSGnHsfzTuIsbthslf5Gqjs"
invoice_number
"15"
dateofbill

sno
array:3 [▼
0 => "1"
1 => "2"
2 => "3"
]
item_name
array:3 [▼
0 => "jeans"
1 => "shirt"
2 => "lower"
]
qty
array:3 [▼
0 => "2"
1 => "3"
2 => "2"

0 => "1200"
1 => "22"
2 => "12"
]

array:3 [▼

2 => "12"

i cannot be able to store this data into a table. i am trying with for loop but getting an error "Undefined offset: 3".
Code inside the controller
for($i=0;$i<=count($request['sno']);$i++)
{
$invoice = new Invoice;
$invoice->sendbill_id=$bill->id;
$invoice->sno=$request['sno'][$i];
$invoice->item_name=$request->item_name[$i];
$invoice->qty=$request->qty[$i];
$invoice->price=$request->price[$i];
$invoice->gst=$request->gst[$i];
$invoice->discount=$request->discount[$i];
$invoice->save();
}
i want to store these 3 values comming in the array form (sno,item_name,qty,price,gst,discount) in 3 diffrent rows
You should try to use laravel eloquent to save it. Here is some example that you can check it out. Laravel : Many to many insertion
The problem you have is indeed your loop: for($i=0;$i<=count($request['sno']);$i++).
To be specific it is this right here <=:
$i<=count()
^^
Take a look at your array:
[
0 => "1"
1 => "2"
2 => "3"
]
You got a total of 3 objects. count($request['sno']) will therefore return 3 since the count() function does not start counting at 0!
However, calling an index (e.g. $request['sno'][1]) will not return the first object (0 => "1") but the second (1 => "2"). I think you see where I am going.
Since the loop will go on until $i equals 3 the loop will be completed 4 times. At the last time (where $i == 3) you try to get the 4th item out of your array which does not exist so an error message pops up: Undefined offset: 3.
To solve this just change this
$i<=count()
^^
to <. The loop will only be executed if $i is still smaller then 3. This is the case if $i == 2. No error message will pop up.
I do not want to attack or hurt you in any way, but it seems to me that you are relatively new to PHP. Of course, that's not a shame, but I'm wondering if a huge framework like Laravel is right for you. First the basics, then comes the advanced.
But that's only as a small comment and tip from me.
I have logic in a controller that builds an array called $exclude.
Using dd for $exclude I get :
array:4 [▼
0 => 2
1 => 3
2 => 4
3 => 5
]
which is correct.
I want to exclude those from a result so I have:
$potype = DB::table('potypes')
->whereNotIn('id',[$exclude])
->get();
but when I run the query those items are included with the exception of the first in the array. So I enabled the query log with
DB::enableQueryLog();
and ran
dd(DB::getQueryLog());
with the result of
array:1 [▼
0 => array:3 [▼
"query" => "select * from `potypes` where `id` not in (?)"
"bindings" => array:4 [▼
0 => 2
1 => 3
2 => 4
3 => 5
]
"time" => 0.67
]
]
The table has 8 records but running the query is returning 7, only ommiting the first of the list:
Collection {#621 ▼
#items: array:7 [▼
If I use implode
$ex = implode(',',$exclude)
and change the query to
->whereNotIn('id',[$ex])
I get the same result - 7 items with just the first in the list being ignored.
Is this an Eloquent bug or me?
delete [ ] and check it again:
$potype = DB::table('potypes')
->whereNotIn('id',$exclude)
->get();
OK it was realtively simple with Mohammed's comment pointing me in the right direction.
As $exclude was an array I changed the get to:
$potype = DB::table('potypes')
->whereNotIn('id',$exclude)
->get();
and it worked OK!
