Im trying to pass params to maat excel import.
I'm doing somethig like this:
JS:
v-for option in options
v-model selection
form = new formData
form.append(users.xls, this.selection)
Controller:
{
Excel::import(new UsersImport, 'users.xlsx');
}
Import class:
class UsersImport implements ToCollection
{
public function collection(Collection $rows)
{
foreach ($rows as $row)
{
User::create([
'name' => $row[0],
'option' => use the selection here
]);
}
}
}
Question im asking is how to get this.selection into the option column through the controller and import class.
Add a constructor to your class and pass it to the constructor:
public function __construct($selection)
{
$this->selection = $selection;
}
// then in the Controller
Excel::import(new UsersImport($something), 'users.xlsx');
Then you can use it in your method as $this->selection.

{
$data = [];
foreach ($failures as $failure) {
$data[] = [
'row' => $failure->row(),

i want to ask, is it possible to import excel excel to import
to the database like database table in php laravel?
of course there is a excelent package for import and export data from excel
Laravel-Excel
here is an example for export excel
class PermissionExport implements FromCollection, ShouldQueue , WithMapping , WithHeadings, WithEvents
{
public function registerEvents(): array
{
return [
BeforeSheet::class =>function(BeforeSheet $event){
$event->getDelegate()->setRightToLeft(true);
}
];
}
public function collection()
{
return Permission::all();
}
public function map($permissions): array
{
return [
$permissions->name,
$permissions->label,
];
}
public function headings(): array
{
return [
'permission name',
'permission description',
];
}
}
and here is and example for import data from excel
class PermissionsImport implements ToModel,WithStartRow
{
/**
* #param Collection $collection
*/
public function model(array $row)
{
return new permission([
'name' => $row[0],
'label' => $row[1],
]);
}
public function startRow(): int
{
return 2;
}
}
I am exporting PDF files with every entry.
But they are too simple, i.e: no styling.
Here is a screenshot:
But as you can see, there is no styling other then the styling is used for my Excel export. I want to add a logo image on top. Remove the extra columns and add some header text like Company name, address etc....
Here is my Controller:
public function export_release(Request $request)
{
Excel::store(new \App\Exports\ReleaseExportView($request->reference),'uploads/release/'.$request->reference.'/'.'release_'.$request->reference.'.pdf','real_public', \Maatwebsite\Excel\Excel::DOMPDF);
return redirect()->route('release_inventory')->with('success','Outbound has been Created.');
}
Here is my Export class:
use App\outbound_detail;
use App\outbound_temp;
use Maatwebsite\Excel\Concerns\FromCollection;
use Illuminate\Contracts\View\View;
use Maatwebsite\Excel\Concerns\FromView;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\ShouldAutoSize;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Events\AfterSheet;
class ReleaseExportView implements FromCollection, WithHeadings, ShouldAutoSize, WithEvents
{
protected $reference;
function __construct($reference) {
$this->reference = $reference;
}
public function collection()
{
//link for StackOverFlow
//https://stackoverflow.com/questions/57153985/how-to-pass-parameter-to-export-file-of-laravel-excel-for-db-query
return outbound_detail::where('reference',$this->reference)->get([
'reference', 'sku_parent', 'sku_child', 'cases'
]);
}
public function headings(): array
{
return [
'Reference',
'SKU Parent',
'SKU Child',
'Cases Released'
];
}
// ...
/**
* #return array
*/
public function registerEvents(): array
{
return [
AfterSheet::class => function(AfterSheet $event) {
$cellRange = 'A1:W1'; // All headers
$event->sheet->getDelegate()->getStyle($cellRange)->getFont()->setSize(14);
},
];
}
}
First of all Remove ShouldAutoSize, to fit the data in your file.
Then edit A1:W1 in AfterSheet. I'm still researching on adding company info also
you can return Blade view instead of array and customize the layout there
public function view(): View
{
$data = [];
return view('yourBladeView', [
'details' => $data
]);
}
I'm trying to make an api that have lists and inside each list there is anther list inside of it called cards and the cards list is the cards of this list.
I tried to show it in index function and didn't work it was like this:
public function index()
{
// $list = List -> cards();
$list = List::cards();
return response( $list );
}
Card Model:
public function list()
{
return $this->belongsTo( List::class() );
}
Card Model:
public function cards()
{
return $this->hasMany( Card::class() );
}
What i want to output is json data like this:
"lists":[
'name':listname
'cards':[
'card one': card name,
]
]
If you use Laravel framework use Resource for response, in Resource of laravel you can load cards. For example in ListController :
public function index()
{
return ListResource::collection(List::all()->paginate());
}
And in ListResource :
public function toArray($request)
{
'cards' => CardResource::collection('cards');
}
belongsTo or hasMany accepts model name as a first argument. In your case you need to pass your model class name in your relations methods.
public function list()
{
return $this->belongsTo(List::class);
}
and
public function cards()
{
return $this->hasMany(Card::class);
}
So if you want to receive models including relations you can use with method.
return response(List::query()->with('cards'));
You can use resources.
Http\Resources\List:
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
class List extends JsonResource
{
public function toArray($request)
{
$cards = [];
foreach ($this->cards as $card) {
$cards[] = $card->name;
}
return [
'name' => $this->name,
'cards' => $cards,
];
}
}
Http\Controllers\ListController:
namespacce App\Http\Controllers;
use App\Http\Resources\List as ListResource;
use App\Components\List;
class ListController extends Controller
{
$lists = List::query()->get();
return ListResource::collection($lists)->response();
}
I have a basic form that contains an excel file upload and a select option.
The select contains a few options. I want to pass the selected option from the user with the file to my Excel::import
I tried passing another parameter to my import but it returns error. (has to be string, array given)
Is this possible using Laravel excel import?
Controller
public function create(Request $request)
{
if($request->hasFile('file'))
{
$package = $request->input('package');
// how can I add $package to my import to insert it to my user model?
Excel::import(new AccountsImport, $request->file('file'));
return ['message' => 'Excel has been succesfully uploaded'];
}
}
AccountsImport
class AccountsImport implements ToCollection, withHeadingRow
{
public function collection(Collection $rows)
{
$rows->each(function($row, $key) {
Account::create([
'name' => $row['student'],
'email' => $row['e_mail'],
// Want it to be possible to add my package here
//'package' => $package
]);
});
}
}
Maybe you could pass down custom data to your AccountsImport class?
You would have a data array as such:
$data = [
'package' => $package,
// other data here
];
You would then do something like this:
Excel::import(new AccountsImport($data), $request->file('file'));
That would require some changes in your import class.
class AccountsImport implements ToCollection, withHeadingRow
{
private $data;
public function __construct(array $data = [])
{
$this->data = $data;
}
public function collection(Collection $rows)
{
$rows->each(function($row, $key) {
Account::create(array_merge([
'name' => $row['student'],
'email' => $row['e_mail'],
// Want it to be possible to add my package here
//'package' => $package
], $this->data));
});
}
}
I took a look at Laravel Excel's API and couldn't see something that would cater for this, but this should work.
