I have done import in laravel 5 but facing some problem while exporting file.
code is not proper and doesnot give any logic.
I have tried similiar to documentation
public function exportData(Test $test,Excel $excel){
$test=$test->all();
Excel::create('Test excel', function($test) {
$test->sheet('sheet1', function($sheet) {
$sheet->setOrientation('landscape');
});
})->export('xls');
}
how to export csv file from mysql?
I am using "maatwebsite/excel": "~2.0.0" package
You can use INTO OUTFILE in Laravel
public function exportData($file_name) {
$file = public_path()."/downloads/".$file_name; //CSV file is store this path
$query = sprintf("select * from tests INTO OUTFILE '%s' FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\n'",$file);
\DB::connection()->getpdo()->exec($query);
}
You might consider using the league/csv package. They have an example of exporting a database query to CSV. In your case, it would look something like:
public function exportData() {
// get the data
$data = Test::all();
// get a Writer object for writing to CSV
$csv = League\Csv\Writer::createFromFileObject(new SplTempFileObject());
// add the data to the writer
$csv->insertAll($data);
// output the file
$csv->output('testdata.csv');
}

I need to write a plugin that exports data both in CSV and XLSX formats*.
As a base I follow Vojta's plugin code (1) that uses ImportExport backend behavior.
The main plugin controller DataImportExport inherits a import-export Behavior from the Backend that is located in the ImportExportController.
class DataImportExport extends Controller
{
public$implement = [
'Backend.Behaviors.ImportExportController',
];
...
}
It's that Behavior that has methods to export data into CSV file. Yet, if I want to export into XLSX file I am supposed to add corresponding methods into that behavior, namely into the exporting controller by overriding some of its existing methods. Yet, as I do that inside DataImportExport controller, it does not work... as I try/test the export process remains the same as it was prior to that with only CSV...
One seems to be not able to override/extend the backend behavior, namely modules\backend\behaviors\ImportExportController.php.
For example, at the DataimportExport controller I try to override the exportFromList() method of ImportExportController behavior by adding code for the XLSX export -
Yet, no positive change... as I try it.
class DataImportExport extends Controller
{
public $implement = [
'Backend.Behaviors.ImportExportController',
];
public function __construct()
{
parent::__construct();
BackendMenu::setContext('RainLab.User', 'user', $this->action);
// extending the ImportExportController behavior
\Backend\Behaviors\ImportExportController::extend(function($model) {
$model->addDynamicProperty('tagsCache', null);
$model->addDynamicMethod('writeXLSX', function() use ($model) {
});
$model->addDynamicMethod('getTagsAttribute', function() use ($model) {
if ($this->tagsCache) {
return $this->tagsCache;
} else {
return $this->tagsCache = $model->tags()->lists('name');
}
});
});
}
...
// method to override
public function exportFromList($definition = null, $options = [])
{
...
$response = Response::make();
if ($options['export_type'] == 'csv') {
/*
* Response CSV
*/
$response->header('Content-Type', 'text/csv');
$response->header('Content-Transfer-Encoding', 'binary');
$response->header('Content-Disposition', sprintf('%s; filename="%s"', 'attachment', $filename));
$response->setContent((string) $csv);
} else {
// export into xlsx code
}
return $response;
}
}
Note
Vojta's plugin exports/imports only into/from CSV files.
maybe you should look at https://octobercms.com/plugin/vdomah-excel where you can import and export CSV and Excel files ? The documentation is very well, and i use it on many projects to import datas and it's working well.
best,

I am using laravel-excel to export csv file. To export, the code is like below,
return Excel::download(new Export(results,$header), "test.csv");
And the Export.php file is like,
namespace App\AllClass;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\Exportable;
use Maatwebsite\Excel\Concerns\WithHeadings;
class Export implements FromCollection,WithHeadings
{
private $myArray;
private $header;
public function __construct($myArray,$header){
$this->myArray = $myArray;
$this->header = $header;
}
public function collection()
{
$data = mb_convert_encoding($this->myArray,"SJIS", "UTF-8");
// dump($data);
return collect($data);
}
public function headings(): array
{
$header = mb_convert_encoding($this->header,"SJIS", "UTF-8");
// dump($header);
return $header;
}
}
As you can see, I am converting the data before creating excel. Without converting I can export perfectly in UTF-8 format. But after converting to shift-jis, it is deleting all Japanese character. However, if I dump the header before returning, it is showing me gibberish data; not empty string like the csv file.
I resolved it.
Let's me share my solution here.
Laravel Excel not support it by default.
But we can do it by simple way.
Get csv content before download: \Excel::raw
Convert to another encoding: mb_convert_encoding
https://docs.laravel-excel.com/3.1/exports/collection.html#storing-raw-contents
Download csv.
$exportedObject= new \App\Exports\ClassExport($exportDataArray, $fileName);
$csvContent = \Excel::raw($exportedObject, $exportedObject->writerType);
$csvContent = mb_convert_encoding($csvContent, 'SJIS', 'auto');
// In my case, I upload my csv to S3.
$storageInstance = \Storage::disk('s3_import_csvs');
$putFileOnStorage = $storageInstance->put($fileName, $csvContent);
In config/excel.php, you should change CSV Settings
'use_bom' => true,
It's work well in Japanese
I'm exporting some Data from a DB and I want to have the 2 columns that I generate Tab separated.
I've already tried to use implode after my fputcsv but it always appears comma separated. Also tried changing my separator (,) to some other character, but a comma is always printed in the CSV.
This is the function that I'm using for it.
public function ResearchExport(Request $request)
{
//Export ProductID and KitID of all the Kits created from the given date to the actual moment
$TubeAddDate = $request->input('TubeAddDate');
$select = DB::table('tubes')->select('TubeBarcodeID', 'ActivationCode')->where('LOG_important', '2')->whereBetween('TubeAddDate', array($TubeAddDate, NOW()))->get();
$tot_record_found=0;
if (count($select)>0) {
$tot_record_found=1;
$CsvData=array('TubeBarcodeID,ActivationCode');
foreach ($select as $value) {
$CsvData[]=$value->TubeBarcodeID.",".$value->ActivationCode.;
}
$filename=date('Y-m-d').".csv"; //stores the file with the date of today as name
$file_path=storage_path().'/'.$filename;
$file = fopen($file_path, "w+");
foreach ($CsvData as $exp_data) {
fputcsv($file, explode(",", $exp_data));
}
fclose($file);
return response()->download($file_path, $filename);
}
return view('InsertForms/download', ['record_found' =>$tot_record_found]);
}
At the moment I'm getting this as output
TubeBarcodeID,ActivationCode
FF01111112,IKG5G-B0FIZ
FF0111113,6XMP8-760Y3
but I expect something tab separated in the CSV like this
TubeBarcodeID ActivationCode
FF01111112 IKG5G-B0FIZ
FF0111113 6XMP8-760Y3
So I actually just solved thanks to one of the commentaries that pointed out my error.
I just had to change my .csv to .xls and then override the third parameter of fputcsv with a "\t".
$filename=date('Y-m-d').".xls"; //stores the file with the date of today as name
$file_path=storage_path().'/'.$filename;
$file = fopen($file_path, "w+");
foreach ($CsvData as $exp_data) {
fputcsv($file, explode(",", $exp_data), "\t");
}
I'm working with Magento 2, I need to read a file through ftp connection. I can login to ftp but I cannot read the csv file. What I did so far (I cut all the unnecessary parts):
use Magento\Framework\File\Csv;
use Magento\Framework\Filesystem\Io\Ftp;
class MyClass {
protected $_csvprocessor;
protected $_ftp;
public function __construct(Csv $csvprocessor, Ftp $ftp) {
$this->_csvprocessor = $csvprocessor;
$this->_ftp = $ftp;
}
public function getCsv() {
$conn = $this->_ftp->open($params); // this works, I can successfully login to ftp
$filecsv = $this->_ftp->read($remotepathtofile); // this gets me the file but it is a string, not an array with the csv data
$this->_csvprocessor->getData($remotepathtofile); // this doesn't work with remote file, only with local path (eg: magentoroot/var/import/file.csv)
}
}
How can I read the csv as an array, as $this->_csvprocessor->getData() would return, but from remote file instead of local?
You need to parse the csv string. Try using the function "fgetcsv". See http://php.net/manual/en/function.fgetcsv.php.
Below the code, you can use to read CSV file an array
use Magento\Framework\App\Bootstrap;
include('app/bootstrap.php');
$bootstrap = Bootstrap::create(BP, $_SERVER);
$objectManager = $bootstrap->getObjectManager();
$objectManager1 = Magento\Framework\App\ObjectManager::getInstance();
$directoryList = $objectManager1->get('\Magento\Framework\App\Filesystem\DirectoryList');
$path = $directoryList->getPath('media');
$state = $objectManager->get('Magento\Framework\App\State');
$state->setAreaCode('frontend');
$myarray = glob("Book1.csv");
usort($myarray, create_function('$a,$b', 'return filemtime($a) - filemtime($b);'));
if(count($myarray)){
/*This will create an array of associative arrays with the first row column headers as the keys.*/
$csv_map = array_map('str_getcsv', file($myarray[count($myarray)-1]));
array_walk($csv_map, function(&$a) use ($csv_map) {
$a = array_combine($csv_map[0], $a);
});
array_shift($csv_map); # remove column header
/*End*/
$message = '';
$count = 1;
foreach($csv_map as $data){
your code....
}
Hope this will help you enjoy...
You can dump the server file to your local.
$filecsv = $this->_ftp->read($remotepathtofile, $destinationFilePath);
where $destinationFilePath is local file path.
Then use that local file.
I have a problem to change the limit of characters in the meta description. I\\’ve modified as shown here:
http://www.magentocommerce.com/boards/v/viewthread/278911/#t392935
But it only detects if you create or modify the product from magento admin and I upload products from .csv file and I have to go one by one to each product in the meta description and then go down from 255 to 155: (
Is there any way to change it without changing it from Magento, I think the problem comes because the code says:
setOnkeyup
Thanks in advance and greetings!
I understand, that you have too long data in your meta_description for each of products.
You can short the value before loading it by layout XML config, or directly by the PHTML template for each page type.
Better way to have result you need is NOT ti import longest data than you need.
Importing unnecessary data solving import and after that you need to correct it again.
Maybe will be better to make script to cut-out meta description in CSV file before you start import to magento.
I solved simmilar issue and make something like this:
(script take your csv file and make new with only 2 columns, SKU and updated text named DECSRIPTION, than you can import to magento after your firs import of csv (first import everything without meta description, after that ONLY your meta description cuted out by 250 chars for example))
//////// get csv and take variable you need in my case is it SKU
$csv = file_get_contents ('myimportfile.csv');
function parse_csv ($csv_string, $delimiter = ";", $skip_empty_lines = true, $trim_fields = true)
{
$enc = preg_replace('/(?<!")""/', '!!Q!!', $csv_string);
$enc = preg_replace_callback(
'/"(.*?)"/s',
function ($field) {
return urlencode(utf8_encode($field[1]));
},
$enc
);
$lines = preg_split($skip_empty_lines ? ($trim_fields ? '/( *\R)+/s' : '/\R+/s') : '/\R/s', $enc);
return array_map(
function ($line) use ($delimiter, $trim_fields) {
$fields = $trim_fields ? array_map('trim', explode($delimiter, $line)) : explode($delimiter, $line);
return array_map(
function ($field) {
return str_replace('!!Q!!', '"', utf8_decode(urldecode($field)));
},
$fields
);
},
$lines
);
}
// list of variables to array
$vystup = parse_csv($csv);
enter code here
After that you can loop each variable to row, modify by PHP what you want:
$seznamsku = array();
foreach ($vystup as $row){
array_push($seznamsku, $sku[0]);
unset($seznamsku[0]);
$seznamskufin = array_filter($seznamsku, 'strlen');
};
foreach ($seznamskufin as $row) {
$__OUT .= ' "ROW_YOURSKU","'.htmlspecialchars(substr(ROW_YOURMETADESCRIPTION, 0, 155)).'"'."\n"; // TODO exactly dont know how to call variables, maybye $row['something'] or $row[0]['something']
};
$feed = fopen($newfile, 'w');
fwrite($feed, $__OUT);
fclose($feed);
//remember to unset variables
you can get another csv file with description long 250 chars and import it to magento
(You must update code it only returns list of SKU, get your descriptions from file);
