Upload File in Edit Multiple Data Form - php

Question

I'm trying to create an edit multiple data form like this using Laravel 8. In the form, you could upload only one file for each row. I could update the data without uploading file, but when I tried to update the file, it redirect me back to the form and no file uploaded. I already add enctype to my form. This is my code:
View:
<div class="custom-file" style="margin-left:10px; margin-right:10px;">
<input type="file" name="bukti[]" class="custom-file-input">
<label class="custom-file-label"></label>
</div>
Controller:
if($request->file('bukti') !=null) {
//upload file
$bukti=array();
if($files=$request->file('bukti')) {
foreach($files as $file) {
$name=$file->getClientOriginalName();
$path=$file->storeAs('blabla',$name);
$bukti[]=$name;
}
}
//Update multiple data
if(count($request->id) > 0) {
foreach($request->id as $item => $v) {
$data = array(
'id_laporan' => $laporan_indikators->id,
'id_pertanyaan' => $request->id_pertanyaan[$item],
'jumlah' => $request->jumlah[$item],
'keterangan' => $request->keterangan[$item],
'bukti' => $bukti[$item],
);
$data_laporans = DataLaporan::where('id',$request->id[$item])->first();
$data_laporans->update($data);
}
}
I already tried to fix it but I still didn't get a solution. Please help me because I'm still a beginner. I'm sorry for my bad English. Thank you.
UPDATE: I already tried to update the code to something like this:
Controller:
//upload file
if($files=$request->file('bukti')) {
foreach($files as $file) {
$name=$file->hashName();
$path=$file->storeAs('blabla',$name);
$bukti=$name;
}
}
//Update multiple data
if(count($request->id) > 0) {
foreach($request->id as $item => $v) {
$data = array(
'id_laporan' => $laporan_indikators->id,
'id_pertanyaan' => $request->id_pertanyaan[$item],
'jumlah' => $request->jumlah[$item],
'keterangan' => $request->keterangan[$item],
'bukti' => $bukti,
);
$data_laporans = DataLaporan::where('id',$request->id[$item])->first();
$data_laporans->update($data);
}
}
It uploaded the file and redirect me back to the index page after updating successfully, but when I check the database, the controller updated all of the bukti column value to the same file name. If I tried to update file for two rows, all of the bukti column is just update the value to the last uploaded file name. What I want is there's just one data for jumlah, keterangan, and one bukti file in a row, so I can have different files for each row. I don't really know how to fix this because I'm still a beginner. Thank you for your help.

Answer 1

Try to add the double question (??) mark for check whether the index of array is available or not:
<?php
if($request->file('bukti') !=null) {
//upload file
$bukti=array();
if($files=$request->file('bukti')) {
foreach($files as $file) {
$name=$file->getClientOriginalName();
$path=$file->storeAs('blabla',$name);
$bukti[]=$name;
}
}
//Update multiple data
if(count($request->id) > 0) {
foreach($request->id as $item => $v) {
$data = array(
'id_laporan' => $laporan_indikators->id,
'id_pertanyaan' => $request->id_pertanyaan[$item],
'jumlah' => $request->jumlah[$item],
'keterangan' => $request->keterangan[$item],
'bukti' => $bukti[$item] ?? '',
);
$data_laporans = DataLaporan::where('id',$request->id[$item])->first();
$data_laporans->update($data);
}
}

Answer 2

After trying for some times, finally I found a solution. Actually, I just need to give a condition if a file is uploaded in certain row.
View:
<div class="custom-file" style="margin-left:10px; margin-right:10px;">
<input type="file" name="bukti_{{ $data->id }}" class="custom-file-input">
<label class="custom-file-label"></label>
</div>
Controller:
if (count($request->id) > 0) {
$bukti = '';
foreach ($request->id as $item => $v) {
$id_item = $request->id[$item];
$file = $request->file('bukti_'.$id_item);
$data = array(
'id_laporan' => $laporan_indikators->id,
'id_pertanyaan' => $request->id_pertanyaan[$item],
'jumlah' => $request->jumlah[$item],
'keterangan' => $request->keterangan[$item],
);
//If file is updated
if ($file) {
$name = $file->hashName();
$path = $file->storeAs('blabla', $name);
$bukti = $name;
$data['bukti'] = $name;
}
$data_laporans = DataLaporan::where('id', $request->id[$item])->first();
$data_laporans->update($data);
}
}
