Export CSV using Laravel via Ajax - php

Question

I have a export csv function, it worked fine with laravel. But now I want to call export function via ajax and use method post, but I there is no respone. I can send a variable from laravel controller to response, but can not send a file download.
Here is my code :
route.php
Route::get('/title/show', 'TitleController#show');
Route::post('/title/show', 'TitleController#exportFromDB');
show.blade.php
<script>
$(document).ready(function () {
$('#exportFromDB').click(function () {
$.ajax({
url: "",
type: "post",
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
data: {},
success: function (response) {
var a = document.createElement("a");
a.href = response.file;
a.download = response.name;
}
})
})
})
TitleController.php:
$dataExport['Oversea'] = $dataOversea;
$this->titleRepository->export('csv', $properties, $dataExport);
TitleRepository.php
public function export($type, $properties, $data)
{
if (in_array($type, self::EXPORT_TYPE)) {
try {
return Excel::create($properties['_title'], function ($excel) use ($data, $properties) {
$excel->setTitle($properties['_title']);
$excel->setCreator($properties['_creator'])
->setCompany($properties['_company']);
$excel->setDescription($properties['_description']);
$excel->sheet('Sheet', function ($sheet) use ($data) {
foreach ($data as $item) {
$sheet->fromArray($item);
}
});
})->export($type);
} catch (Exception $error) {
throw $error;
}
}
}
How can I fix them ? Thank !

Answer 1

Try this -
Don't write the code for export in your controller method, instead just save the excel file in your public folder.
Your controller method should return the filename.
On your ajax success do this -
location.href = path/to/file/property_title.xls
So replace your this line
->export($type);
with
->store($type, 'public/reports/', true);

I see your ajax url null value
Change it to
url : "{{ action('TitleController#exportFromDB') }}"
After that, response is data you return in controller
success: function (response) {}

I installed the maatwebsite/excel package and was able to do it without writing any javascript. All you need to do is setup a link (or typical form post if you prefer) to an action like so:
public downloadItemsExcel() {
$items = Item::all();
Excel::create('items', function($excel) use($items) {
$excel->sheet('ExportFile', function($sheet) use($items) {
$sheet->fromArray($items);
});
})->export('xls');
}
This works for csv/excel files alike. There is no reload of a page in the browser.

First you have to change POST method to GET.
For ajax you can do it like this:
$(document).ready(function () {
$('#exportFromDB').click(function () {
$.get('/title/show, function(data){
window.location = '/title/show=' + data;
});
})
})
