Files not uploading due to unkown error using laravel - laravel

Question

Laravel Version: 5.5
I have a problem when uploading a file. I have multiple files in the array, I am uploading these files two times in the same function for the first time I am checking pdf file version, and file dimensions this block of code works perfectly but in the second block of code I am again uploading these files for merging these files it gives me this error "The file "A4.pdf" was not uploaded due to an unknown error". When I remove the first block of code then the second block of code start working.I don't know where I did mistake, I have searched a lot but not found the answer.
This block of code checking pdf file version and dimensions.
$paper_size = array();
$del_files = array();
foreach ($files as $file) {
$filename = time().date('m-d-y').$file->getClientOriginalName();
$file->move(public_path().'/uploads/check_pdf_files/', $filename);
$version = $this->pdfVersion(public_path().'/uploads/check_pdf_files/'.$filename);
if($version > 1.5)
{
File::delete('public/uploads/check_pdf_files/'.$filename);
return Response::json(" Your PDF file version is greater than 1.4 which is not compatible with our system, Please make it lower version.", 400);
}
$get_paper_size = $this->get_pdf_dimensions('public/uploads/check_pdf_files/'.$filename);
$paper_size[] = $get_paper_size;
$del_files[] = $filename;
}
if(round($paper_size[0]['width']) != round($paper_size[1]['width']))
{
foreach ($del_files as $del)
{
File::delete('public/uploads/check_pdf_files/'.$del);
}
return Response::json(" Your Files dimensions is not matching please try with same dimensions.", 400);
}
This block of code using for merging the files.
$new_pdf_file = array();
foreach ($request->file as $merge_file)
{
$newFile_name = time().$merge_file->getClientOriginalName();
$merge_file->move('public/uploads/', $newFile_name);
$new_pdf_file[] = $newFile_name;
}
dd($new_pdf_file);
$pdf = new \LynX39\LaraPdfMerger\PdfManage;
foreach($new_pdf_file as $new)
{
$pdf->addPDF('public/uploads/dummy_uploads/'.$new, 'all');
}
$temp_name = time().$request->merge_name;
$pdf->merge('file',base_path(). '/public/uploads/' . Auth::user()->email . '/'.$temp_name.'.pdf', 'P');
foreach($new_pdf_file as $delete_new)
{
File::delete('public/uploads/dummy_uploads/'.$delete_new);
}
$user = DB::table('user_pdf_files')->insert([
'user_files' => $request->merge_name.'.pdf',
'filename' => $temp_name.'.pdf',
'type' => $request->type[0],
'user_id' => Auth::user()->id,
]);
Session::flash('success', 'Files Merged Successfully');
return Response::json('success', 200);`

You need the fully qualified path to where you want the files saved to. Anytime you are moving or copying a file, ensure that you are using public_path() with the relative path as a parameter. This function outputs the fully qualified path to the public folder. For example:
$merge_file->move(public_path('uploads'), $newFile_name);
This should be why the first code block is working vs. the second one. Not a very descriptive error, though!
