Replied to Passing Variable From Controller To Blade With Loop (@for Inside @foreach)

Started a new Conversation Passing Variable From Controller To Blade With Loop (@for Inside @foreach)

Hello Everyone!

I have created a database table inside my controller and populated it. Variable $i is initialized ($i=1). $n is inserted by the user and represents year values. Score is the year sum for each year per individual. The following code is the controller excerpt with the table creation which works right (using the while loop the table columns year(i) are automatically created depending on n value).

$n  = $p -> input('n');
$i = 1;  //initialization

if (Schema::hasTable('abc'))     
Schema::create('abc', function (Blueprint $table) use ($n, $i)  
		$table->string('last_name') -> nullable();		
		$table->string('first_name') -> nullable(); 
			while($i <= $n) 
					$table->integer('year'.$i.'') -> nullable();

		$table->decimal('score', 5, 4) -> nullable();

//code bla bla bla

$data = DB::table('abc') ->get();   // We collect everything and store into $data
return view('result', ['data'=>$data, 'n'=>$n]);

My question has to do with the result blade where I fail to produce the results for the value of year(i) for i values in 1<= i <=n. Below is my result.blade.php excerpt. I want to pass year1, year2,... to the respective headings. I have tried many different combinations but always with an error (I want to produce something like {{ $v2 -> year }}.{{ i }}).

<table border="1">
        <th>LAST NAME</th>
        <th>FIRST NAME</th>
       		@for($i = 1; $i <= $n; $i++)
		<th>YEAR{{ $i }}</option></th>      // --> THIS WORKS (we get year1, year2,... table headings right)!!
	<th>Total Score</th>

@foreach($data as $v2)
        	<th>{{ $v2->aa }}</th>
       		 <td>{{ $v2->last_name }}</td>
		<td>{{ $v2->first_name }}</td>
			@for($i = 1; $i <= $n; $i++)
				<td>{{ $v2 -> year  }}.{{ i }}</td>   // --> HERE IS MY PROBLEM!! <--
		<td>{{ $v2->score }}</td>    	



Thank you a lot!!

Replied to Requesting User Where To Save Exported File

Hello @snapey

Upon LAN users request execution on server, the code runs and saves zip file inside laravel's public folder on server, but users are not prompted to download it.

I added that line to the excerpt above

return response()->download(public_path('zipped_gr_'.$we.'.zip'));

but I get error

"C:\xampp\htdocs\laravel\public\zipped_gr_16072020100113.zip" does not exist.

But zipped_gr_16072020100113.zip exists in public folder.

Started a new Conversation Requesting User Where To Save Exported File

Hello everyone.

I use phpWord library for creating MS-Word forms in laravel. The forms are named after several id numbers (e.g. 1021052.doc, 1021053.doc etc). After the forms are created, they are zipped using the Zip library. The zip file is saved inside \laravel\public\ folder as zipped_gr_[current date and time].zip file.

I want each time the code is run and the zip file is created, the user to be asked where to save that zip file (eg desktop). And how can this be done when the laravel project is running on the server over the network?

What I have done:

This is my controller code performing the specific operation:

foreach($regs as $i) 


....  //code

$objWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'Word2007');

//this saves files inside laravel\storage\zipped_gr folder for each id
		catch (Exception $e) 
			return response()->download(storage_path('zipped_gr\.'.$i->id.'_gr.docx')); 
}   //foreach ends here
$we = Carbon::now();  
$we = Carbon::createFromFormat('Y-m-d H:i:s', $we)->format('dmYHis');

$zip = Zip::create('zipped_gr_'.$we.'.zip');   
$zip->add('c:\xampp\htdocs\laravel\storage\zipped_gr'); //this saves inside public as 
//	zipped_gr_16072020075926

Thank you a lot!

Replied to Shibboleth Authentication

Hi @prasadchinwal5 !

Well, it seems the time to put server into production environment has come. The laravel project is installed on our server (I haven't added shibboleth package yet on it).

However, as mentioned in previous post, I have installed shibboleth with Shibalike emulation on my windows laptop laravel project, following https://github.com/uabookstores/laravel-shibboleth guide and secured (with success) a desired route by applying the following excerpt inside the corresponding blade

@if (Auth::guest())
    <a href="/shibboleth-login">Login</a>
    <a href="/shibboleth-logout">
        Logout {{ Auth::user()->name }}

Now, regarding the server, I guess I should add shibboleth package omitting the steps for shibalike emulation. How should I edit config/shibboleth.php for existing organization users? Is just this needed for users to be prompted for their individual authentication credentials when trying to open the specific link?

Thank you a lot!

Replied to Formatting Exported Excel File

Hi @deepu07

I have declared my border style as below:

//border style
		$styleArray = [
				'borders' => [
					'outline' => [
						'borderStyle' => \PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THIN,
					//'color' => ['argb' => 'FFFF0000'],

This is later used like this:

 return [
            AfterSheet::class => function(AfterSheet $event) use ($styleArray, $styleArray1, $styleArray2, 
            $styleArray3, $styleArray4 , $styleArray5)

To help you more, I have attached the solution I applied on the whole, rearding the styling I have used. I have formatted headings, added borders and fixed width. Each type of format I have used ($styleArray1, $styleArray2, ...) is well declared.

I hope I have helped!
