Laravel How to upload EXCEL file to database? - php

Question

My Laravel version is 5.6.and PHP is 7.
I found some upload sample on the internet, but most of them do not work.
Have anyone can provide a complete example to me?
I found a similar case on the Internet.
Laravel 5.6 Excel and CSV import export using maatwebsite example
Unfortunately, it doesn't work, too.
Here is my source code.
blade.php
<form class="form-upload" method="POST" action="{{url('/excelUpload')}}" enctype="multipart/form-data">
{{ csrf_field() }}
<div class="form-group">
<label for="file">excel upload</label>
<input type="file" id="file" name="ex_file">
<p class="help-block">!!!</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default">cancel</button>
<button type="submit" class="btn btn-primary" id="upload_f">submit</button>
controller.php
public function excelUpload(Request $request){
if($request->hasFile('StudentUploadSample')){
return "yes i have a file";
}
return "nofile";
}
However, the result always show "nofile".
I didn't use any "use". Should I use something?
The example on the web page does not use any "use", too.
In addition, I read some of the websites that the files will be placed under the storage folder, but I can't find my file "StudentUploadSample.xlsx" in the storage folder.
Have anyone can provide a complete example to me or how to solve this problem?

Answer 1

Replace the name of file and use the reference site where you will get the proper code with explanation.
Reference site like: http://www.expertphp.in/article/laravel-5-maatwebsite-import-excel-into-db-and-export-data-into-csv-and-excel
public function importFileIntoDB(Request $request){
if($request->hasFile('sample_file')){
$path = $request->file('sample_file')->getRealPath();
$data = \Excel::load($path)->get();
if($data->count()){
foreach ($data as $key => $value) {
$arr[] = ['name' => $value->name, 'details' => $value->details];
}
if(!empty($arr)){
\DB::table('products')->insert($arr);
dd('Insert Record successfully.');
}
}
}
dd('Request data does not have any files to import.');
}

Answer 2

You use the wrong name of the file in your controller:
if($request->hasFile('ex_file')){
return "yes i have a file";
}
So fix that, and try to check.

Answer 3

replace <input type="file" id="file" name="ex_file"> with <input type="file" id="file" name="StudentUploadSample">
and you are done.

Answer 4

you can use laravel excel.
address：https://github.com/Maatwebsite/Laravel-Excel
/**
* my Controller code
*
*/
$updateFile = $request->file('update_file');
$fileSize = (int) filesize($updateFile);
$fileExtension = $updateFile->getClientOriginalExtension();
$filePath = $updateFile->getRealPath();
$excelData = Excel::load($filePath)->get()->toArray();
