I need to return to controlling the id of the products entered by the excel import.
ProductImport.php
<?php
namespace App\Imports;
use App\Product;
use Illuminate\Support\Collection;
use Maatwebsite\Excel\Concerns\ToCollection;
class ProductImport implements ToCollection {
public function collection(Collection $rows) {
foreach ($rows as $row) {
$product = Product::create([
'name' => $row[0],
'detail' => $row[1]
])->id;
}
return $product;
}
}
ProductController.php
public function uploadProducts(Request $request) {
$request->validate([
'import_file' => 'required|file|mimes:xls,xlsx'
]);
$path = $request->file('import_file');
$import = new ProductImport;
Excel::import($import, $path);
//Here, how can I return the id of the products that were entered?
return response()->json(['message' => 'uploaded successfully'], 200);
}
I have not found a way to return variables in excel import. Thanks for your help.
You can do this by public variable of ProductImport class and then use it in your Controller.
First, create one public variable $product_ids in Import class, assign it all ids
class ProductImport implements ToCollection
{
public $product_ids; // declare one public variable
public function collection(Collection $rows)
{
foreach ($rows as $row) {
// store created product ids as array
$this->product_ids[] = Product::create([
'name' => $row[0],
'detail' => $row[1]
])->id;
}
return $product;
}
}
Now you can use the Import class variable in your Controller as below.
$import->product_ids;
Full code:
public function uploadProducts(Request $request)
{
$request->validate([
'import_file' => 'required|file|mimes:xls,xlsx'
]);
$path = $request->file('import_file');
$import = new ProductImport;
Excel::import($import, $path);
dd($import->product_ids); // it will return you an array
return response()->json(['message' => 'uploaded successfully'], 200);
}
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.
I am using vue with laravel. I am trying to save array of objects but not able to do it though i am able to save single object. Here is my code
App.vue
// Not working
saveData(){
this.axios.post('/addperson', **this.rows**).then((response) => {
console.log("WOW");
})
}
//working
saveData(){
this.axios.post('/addperson', **this.rows[0]**).then((response) => {
console.log("WOW");
})
}
Here is controller code where i am getting error when i pass array.
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\OrderPerson;
class PersonController extends Controller
{
public function create(Request $request){
$person = new Person([
'name' => $request->get('name'),
'age' => $request->get('age'),
'user_id' =>$request->get('user_id')''
]);
$person->save();
return response()->json('Successfully added');
}
}
Can any body help me to save the array?
First of all assign all the this.rows to a data set then push it to the axios call something like this:
saveData(){
const postData = {
data: this.rows
}
this.axios.post('/addperson', postData).then((response) => {
console.log("WOW");
})
}
Now in laravel controller you can use foreach to use this data set.
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\OrderPerson;
class PersonController extends Controller
{
public function create(Request $request){
foreach($request->data as $data)
{
$container = new Person([
'name' => $data['name'],
'age' => $data['age'],
'user_id' => $data['user_id']
]);
$container->save();
}
return response()->json('Successfully added');
}
}
Hope this helps.
