I am fetching count. My target is to display it in ASCENDING ORDER. i have tried to sort it using sort($match); but i have still failed to achieve my goal. Thank you. Any help will be appreciated
Controller:
function asdasdas(){
$entry= $this->repo->entryfetch();
$data='<table>
<thead><tr><th>NO. </th></tr></thead>';
foreach($entry as $entry){
$match= $this->repo->matchfetch($entry->handlerID);
$data.='<thead><tr><th><hr>'.$entry->handlerID.' '.$entry->entryName.'</th> ';
foreach($match as $match){
$diff = $match->weightM - $match->weightW;
if($match->handlerIDM === $entry->handlerID){
$name=$match->handlertestW;
$count=$match->countM;
}else{
$name=$match->handlerM;
$count=$match->countW;
}
$data.='<tbody><tr><td>'.$count.'</td>';
$data.='<td></td></tr></tbody>';
//
}
}
$data .='<table>';
echo $data;
sort($match); // i have tried to sort it using this but it is not working.
}
You can loop the array from the last index to 0
function asdasdas()
{
$entry = $this->repo->entryfetch();
$data = '<table>
<thead><tr><th>NO. </th></tr></thead>';
for ($j = count($entry) - 1; $j >= 0; $j--) {
$match = $this->repo->matchfetch($entry[$j]->handlerID);
$data .= '<thead><tr><th><hr>' . $entry[$j]->handlerID . ' ' . $entry[$j]->entryName . '</th> ';
for ($i = count($match) - 1; $i >= 0; $i--) {
$diff = $match[$i]->weightM - $match[$i]->weightW;
if ($match[$i]->handlerIDM === $entry[$j]->handlerID) {
$name = $match[$i]->handlertestW;
$count = $match[$i]->countM;
} else {
$name = $match[$i]->handlerM;
$count = $match[$i]->countW;
}
$data .= '<tbody><tr><td>' . $count . '</td>';
$data .= '<td></td></tr></tbody>';
}
}
$data .= '<table>';
echo $data;
}
Context is not much clear. Do you need to sort $match before for loop or while inside the forloop. Can you explain a bit if haven't got the solution.

Is it possible to customize the chunk configuration in Filepond such that the chunk information is provided to the upload server:
as query parameters instead of headers
with custom query parameter names instead of Upload-Length, Upload-Name, and Upload-Offset
I am trying to fit Filepond's chunk implementation to a third party upload endpoint that I don't have control over.
I have found the Advanced configuration where you provide a process function which I've played with a little bit to see what comes through the options param -- however that appears (I think) to make the chunking calculations my responsibility. My original thought was to manipulate the options.chunkServer.url to include the query params I need but I don't believe this processes individual chunks.
In case it makes a difference, this is being done in React using the react-filepond package.
I made and implementation in Laravel 6 using Traits and some "bad practices" (I didn't have time because ... release in prod) to join chunks into a file
Basically:
post to get unique id folder to storage
get chunks and join together
profit!
Here's the full code:
<?php
namespace App\Http\Traits\Upload;
use Closure;
use Faker\Factory as Faker;
use Illuminate\Http\Request;
use Illuminate\Http\UploadedFile;
use Illuminate\Support\Facades\Storage;
trait Uploadeable
{
public function uploadFileInStorage(Request $request, Closure $closure)
{
// get the nex offset for next chunk send
if (($request->isMethod('options') || $request->isMethod('head')) && $request->has('patch')) {
//get the temp dir
$dir = $request->patch . DIRECTORY_SEPARATOR;
// reead all chunks in directory
$patch = collect(Storage::files($dir))
->sortBy(function ($file) {
return Storage::lastModified($file);
});
// read offsets for calculate
$offsets = array();
$size = 0;
$last_offset = 0;
foreach ($patch as $filename) {
$size = Storage::size($filename);
list($dir, $offset) = explode('file.patch.', $filename, 2);
array_push($offsets, $offset);
if ($offset > 0 && !in_array($offset - $size, $offsets)) {
$last_offset = $offset - $size;
break;
}
// last offset is at least next offset
$last_offset = $offset + $size;
}
// return offset
return response($last_offset, 200)
->header('Upload-Offset', $last_offset);
}
// chunks
if ($request->isMethod('patch') && $request->has('patch')) {
// get the temp dir
$dir = $request->patch . DIRECTORY_SEPARATOR;
// read headers
$offset = $request->header('upload-offset');
$length = $request->header('upload-length');
// should be numeric values, else exit

// get the file name

// sleep server for get a diference between file created to sort

I am getting an array from database table and through a for each statement. Then check the difference between two values if there is any difference that is less than zero sets a value to 0 for that loop. Then do the same with the next loop.
$bom_id = App\Models\Bom::where('item_id', $item->order_item->id)->pluck('id')->first();
if ($bom_id > 0) {
$bomList = App\Models\Bom_list::where('bom_id', $bom_id)->get();
echo '<div class="row">';
foreach ($bomList as $bomlist) {
$availableQty = $item->order_item->qty;
$requiredQty = $bomlist->qty * $item->qty;
$dif = $availableQty - $requiredQty;
}
$check = '';
$arr = array($bomlist->$dif);
$light = in_array($check, $arr, true) ? 0 : 1;
} else {
$light = 0;
}

I have two model : User & Book. I want create a book for each user with a specific QR code
$users = User::get();
$date = ... ;
$finalCount = 0;
$code = 150;
$userCount = count($users);
foreach ($users as $user) {
$book = new Book();
$book->unique_id = uniqid('', true);
$book->user_id = $user->unique_id;
$book->code = "PP-" . strval(mt_rand(100, 999)) . strval($code);
$book->create_date = $date;
$book->status = 'active';
$book->save();
$QRCode = new BaconQrCodeGenerator;
$file = public_path('/images/book/' . $book->code . '.png');
$QRCode->encoding('UTF-8')
->format('png')
->merge('/public/image/logo.png', .15)
->size(1000)
->generate($book->unique_id, $file);
if (File::exists($file))
$finalCount++;
$code++;
if ($finalCount == $userCount)
break;
}
After this function called, i have 20 book for each user. I used an if statement for break the loop ( if ($finalCount == $userCount) ) but it doesn't work.
I can't understand whats going on here and also i have not any error log
Instead of
$file = public_path('/images/book/' . $book->code . '.png');
try
$file = public_path().'/images/book/' . $book->code . '.png';
I'm trying to develop an algorithm to create a symfony template service.
I want to check if a template exists in a subset of paths, ordered.
Given an array of parameter like this (already ordered like I want):
$params = ['O', 'U', 'W', 'P']
How can I output this array?
$urls = [
'O/U/W/P/template',
'O/U/W/template',
'O/U/P/template',
'O/U/template',
'O/W/P/template',
'O/W/template',
'O/P/template',
'O/template',
'U/W/P/template',
'U/W/template',
'U/P/template',
'U/template',
'W/P/template',
'W/template',
'P/template',
'template'
];
I can perform for a little list of parameters (like everyone can do it I suppose) with a code like this :
private function getPaths($template, $params)
{
$urls = [];
$alreadyPerform = [];
$paramsCounter = count($params);
for ($i = 0; $i < $paramsCounter; $i++) {
for ($j = 0; $j < $paramsCounter; $j++) {
if ($i !== $j && !in_array($params[$j], $alreadyPerform, true)) {
$urls[] = sprintf(
'/%s/%s/%s.html.twig', $params[$i], $params[$j], $template
);
}
}
$alreadyPerform[] = $params[$i];
$urls[] = sprintf('/%s/%s.html.twig', $params[$i], $template);
}
$urls[] = sprintf('%s.html.twig', $template);
return $urls;
}
This function work like I wanted until today (max 3 parameters), but I want to add one parameters today, maybe more after.
Thank you very much for your help !
Cheers.
Using recursion, you can do the following:
/**
* #param array $elements
* #param array $extra
*
* #return Generator
*/
function gen(array $elements, array $extra = []): \Generator {
foreach ($elements as $i => $head) {
foreach (gen(array_slice($elements, $i + 1), $extra) as $tail) {
yield array_merge([$head], $tail);
}
}
yield $extra;
}

Or without recursion:
/**
* #param array $elements
*
* #return Generator
*/
function gen2(array $elements): \Generator {
for ($num = count($elements), $i = pow(2, $num) - 1; $i >= 1; $i -= 2) {
$r = [];
for ($j = 0; $j < $num; $j += 1) {
if ($i & (1 << ($num - $j - 1))) {
$r[] = $elements[$j];
}
}
yield $r;
}
}

Consider using the following package:
https://github.com/drupol/phpermutations
Just a very basic example of what it can do:
$permutations = new \drupol\phpermutations\Generators\Permutations(['A', 'B', 'C'], 2);
foreach ($permutations->generator() as $permutation) {
echo implode('/', $permutation);
echo "\n";
}

I am trying to unlink files that were created the day before
I have a custom application > core > MY_Log.php file and it creates a log for each error level. For easier reading.
logs > DEBUG-04-08-2016.php
logs > ERROR-04-08-2016.php
logs > INFO-04-08-2016.php
logs > DEBUG-03-08-2016.php
logs > ERROR-03-08-2016.php
logs > INFO-03-08-2016.php
Question how am I able to modify the write_log so could delete / unlink files that were created the day before?
<?php
class MY_Log extends CI_Log {
public function write_log($level, $msg)
{
if ($this->_enabled === FALSE)
{
return FALSE;
}
$level = strtoupper($level);
if (( ! isset($this->_levels[$level]) OR ($this->_levels[$level] > $this->_threshold))
&& ! isset($this->_threshold_array[$this->_levels[$level]]))
{
return FALSE;
}
$filepath = $this->_log_path . $level .'-'. date('d-m-Y').'.'.$this->_file_ext;
$message = '';
if ( ! file_exists($filepath))
{
$newfile = TRUE;
// Only add protection to php files
if ($this->_file_ext === 'php')
{
$message .= "";
}
}
if ( ! $fp = #fopen($filepath, 'ab'))
{
return FALSE;
}
flock($fp, LOCK_EX);
// Instantiating DateTime with microseconds appended to initial date is needed for proper support of this format
if (strpos($this->_date_fmt, 'u') !== FALSE)
{
$microtime_full = microtime(TRUE);
$microtime_short = sprintf("%06d", ($microtime_full - floor($microtime_full)) * 1000000);
$date = new DateTime(date('d-m-Y H:i:s.'.$microtime_short, $microtime_full));
$date = $date->format($this->_date_fmt);
}
else
{
$date = date($this->_date_fmt);
}
$message .= $this->_format_line($level, $date, $msg);
for ($written = 0, $length = strlen($message); $written < $length; $written += $result)
{
if (($result = fwrite($fp, substr($message, $written))) === FALSE)
{
break;
}
}
flock($fp, LOCK_UN);
fclose($fp);
if (isset($newfile) && $newfile === TRUE)
{
chmod($filepath, $this->_file_permissions);
}
return is_int($result);
}
}
First of use
$config['log_threshold'] = 1;
For only error message, so there will be less number of files
Add below code just before $filepath; to delete previous date logs
$unlink_date = date('Y-m-d',strtotime("-1 days"));
$filepath_unlink = $this->_log_path . $level .'-'. $unlink_date.'.'.$this->_file_ext;
if ( file_exists($filepath_unlink))
{
unlink($filepath_unlink);
}
