Encrypt a password using Salt UTF-16 - salt

I need to encrypt a password using salt and it must be UTF 16.
This is what i have at the moment but they told me its UTF-8
$key = 'dfs7dsfsdf';
$timestamp = '201705111500';
$concat = $key . $timestamp;
$hash = hash('sha256', $concat);

Try this
$key = 'dfs7dsfsdf';
$timestamp = '201705111500';
$concat = $key . $timestamp;
$cString = mb_convert_encoding($total, "UTF-16LE");
$hash = hash('sha256', $cString);
You forgot
$cString = mb_convert_encoding($total, "UTF-16LE");

Unable to save base 64 Image in Laravel 8

I am trying to save base64 image that is coming from the ajax post (blade file). Below is the code that I am using to save the data but it is giving 500 error.
public function add_ref_images_first(Request $request){
$fileName = "";
$end_url = "";
$count = 0;
$folder_name = 'PUBP' . time();
foreach ($request->images as $data){
$image_64 = $data['src']; //your base64 encoded data
$extension = explode('/', explode(':', substr($image_64, 0, strpos($image_64, ';')))[1])[1]; // .jpg .png .pdf
$replace = substr($image_64, 0, strpos($image_64, ',')+1);
//
// // find substring fro replace here eg: data:image/png;base64,
//
$image = str_replace($replace, '', $image_64);
$image = str_replace(' ', '+', $image);
$ref_image_id = 'PUBR'.time().$count++.'.'.$extension;
$fileName = base64_decode($image)->storeAs($folder_name, $ref_image_id , ['disk' => 'my_uploaded_files']);
if($imageName){
$end_url = $end_url.$imageName.',';
}
}
return response()->json(['url' => $end_url, 'id' => '1']);
}
Is there issue with the code?
instead of the line
$fileName = base64_decode($image)->storeAs($folder_name, $ref_image_id , ['disk'
=> 'my_uploaded_files']);
you can do :
use Illuminate\Support\Facades\Storage;
Storage::put($ref_image_id, base64_decode($image), 'local');
because basically you were trying storeAs on a string value, storeAs works on $request->file('nameFromForm')

How to save Base64 string as Image in laravel

I have been searching for the past 2 days now trying to get a solution that decodes base64 in all file type extensions(.png or jpg). All I found was a base64 decoder that only allow one type of extensions.
My Controller:
public function updatepicture(Request $request){
$user = User::find($request->id);
if($user == null){
return response()->json(['statusCode'=>'5', 'statusMessage' => "user account doesn't exists", 'data' => []]);
}
$image = $request->avatar; // your base64 encoded
$decoded_file = base64_decode($image); // decode the file
$mime_type = finfo_buffer(finfo_open(), $decoded_file, FILEINFO_MIME_TYPE); // extract mime type
$extension = $this->mime2ext($mime_type); // extract extension from mime type
$image = str_replace('data:image/'.$extension.';base64,', '', $image);
$image = str_replace(' ', '+', $image);
$filename = str::random(10).'.'.$extension;
//$image = $request->file('avatar');
//$filename = time().'.'.$image->getClientOriginalExtension();
$filePath = 'avatars/'.$filename;
$disk = Storage::disk('gcs')->put($filePath, file_get_contents(base64_decode($image)));
$gcs = Storage::disk('gcs');
$url = $gcs->url('avatars'. "/" . $filename);
$user->avatar = $url;
$user->save();
return response()->json(['statusCode'=>'0', 'statusMessage' => 'Successful','data' => $user], 200);
}

Please help me align this piece of code, the error massage m getting is as follow:
ErrorException: file_get_contents() expects parameter 1 to be a valid path, string given in file
You don't need to use file_get_contents() function while using put method because you are already converting string to image using base64_decode method.
$disk = Storage::disk('gcs')->put($filePath, base64_decode($image));
Please try like this. It should work.

how to add uniqid in image upload in laravel

I have a function to insert data in a table and this data includes image/file . I think my form didn't have problem but after I added this uniqid(), it can't be submitted with error "Call to a member function getClientOriginalExtension() on null"
public function store_pelatihan(Request $request)
{
$this->validate($request,[
// 'title' => 'required|min:5',
// 'description' => 'required|min:5|max:14'
] );
if($request->hasfile('file_scan'))
{
$file = $request->file('file_scan');
$name=$file->getClientOriginalName();
$extension = $request->image->getClientOriginalExtension();
$fileName = $file.'.'.uniqid().'.'.$extension;
$file->move(public_path().'/files/', $fileName);
$data = $fileName;
}
$users = new Master_seminar_pelatihan;
$users->user_id = $request->user_id ;
$users->nama_pelatihan = $request->nama_pelatihan ;
$users->nomor_pelatihan = $request->nomor_pelatihan ;
$users->tanggal = $request->tanggal ;
$users->uraian = $request->uraian ;
$users->tempat = $request->tempat ;
$users->file_scan = $data;
dd($data);
// $users->save();
// return redirect ('pelatihan')->with('success', 'Input Succes');
}
Previously, I was running this code and it was running without error:
$extension = $request->image->getClientOriginalExtension();
$fileName = $file.'.'.uniqid().'.'.$extension;
change this line :
$request->image->getClientOriginalExtension()
to :
$file->getClientOriginalExtension()
If you're concatenating with '.' before uniqid() it'll take extension so either you use '-' or '_'.
$fileName = $file.'_'.uniqid().'.'.$extension;
Or
$fileName = $file.'-'.uniqid().'.'.$extension;
Check file isValid() first
Get getClientOriginalExtension() of the $file (not $request->image)
Do not concatenate $file (it is UploadedFile) variable with strings. $name should be instead
if ($request->hasfile('file_scan') && $request->file('file_scan')->isValid()) {
$file = $request->file_scan;
$name = $file->getClientOriginalName();
$extension = $file->getClientOriginalExtension();
$fileName = $name . '.' . uniqid() . '.' . $extension;
$file->move(public_path() . '/files/', $fileName);
$data = $fileName;
}

Laravel: Array to string conversion

SettingController.php
public function SendPicture(Request $request) {
$title = "Picture Purchase";
$domain = $_SERVER['SERVER_NAME'];
$email = DB::table('users') - > where('domain', $domain) - > get();
$content = "$email purchase your picture : ";
foreach($request - > input('pic') as $key => $value) {
$content. = "$value".".jpg ";
}
}
ErrorException in SettingController.php line 373: Array to string
conversion
line 373: $content = "$email purchase your picture : ";
If you've only one record you can use value method for getting direct string:
$email = DB::table('users')->where('domain', $domain)->value('email');
$content = $email ." purchase your picture : ";
Note : There is a logical error in your each loop too, remove "" from $value :
foreach($request->input('pic') as $key => $value) {
$content. = $value.".jpg ";
}
$email variable have more then one record. If you use $email as email address from users table then you can follow below code :
$email = DB::table('users')->where('domain', $domain)->first();
$content = $email."purchase your picture : ";
Hope this help for you!!!

how to export a table to csv format and save it on specified folder

i want to export a table to a csv file. that file should save to a folder in assets. here i am using force download.How can set path to the downloading csv file? And is there any other method to save the table as csv file to a specified folder.? pls help me ..
$this->load->dbutil();
$this->load->helper('file');
$this->load->helper('download');
$delimiter = ",";
$newline = "\r\n";
$filename = "filename.csv";
$query = "SELECT * FROM cyber_details";
$result = $this->db->query($query);
$data = $this->dbutil->csv_from_result($result, $delimiter, $newline);
force_download($filename, $data);
I assume that you want to save CSV file on server end.
you can do as following
$this->load->dbutil();
$this->load->helper('file');
$this->load->helper('download');
$delimiter = ",";
$newline = "\r\n";
$filename = "filename.csv";
$query = "SELECT * FROM cyber_details";
$result = $this->db->query($query);
$data = $this->dbutil->csv_from_result($result, $delimiter, $newline);
if ( ! write_file('./path/to/file/file_name.csv', $data))
{
echo 'Unable to write the file';
}
else
{
echo 'File written!';
}
make sure the path you choose has enough permission to perform write operation.
try this, worked for me:
function createcsv(){
$this->load->dbutil();
$this->load->helper('file');
$this->load->helper('download');
$delimiter = ",";
$newline = "\r\n";
$filename = "filename.csv";
$query = "SELECT * FROM YourTable";
$result = $this->db->query($query);
$data = $this->dbutil->csv_from_result($result, $delimiter, $newline);
force_download($filename, $data);
}
I also had come through the same issue.
Below code worked good enough for me.
$arry_to_csv[] = $data;
$output_file_name = 'path/to/Rejected.csv';
$temp_memory = fopen($output_file_name, 'w');
$csv_headers = array_keys($arry_to_csv[0]);
$delimiter = ",";
fputcsv($temp_memory, $csv_headers, $delimiter);
$csv = '';
foreach ($arry_to_csv as $line) {
$csv.= $line['first_name'] . ',' . $line['last_name'] . "\n";
}
fwrite($temp_memory, $csv);
fclose($temp_memory);
