Hello it's me again :)

I built a dashboard looking like this:

Below of "STD-Datei löschen" I want to build a form with a select-field to select a file for deleting it. What I have done is buuilding an action:

namespace App\KV\Dashboard\Actions;

use App\KV\Dashboard\Elements\StdSelect;
use Illuminate\Support\Facades\File;
use koolreport\dashboard\notifications\Note;

class HmStdDelete extends \koolreport\dashboard\admin\actions\Action
{
    

    protected function form(){
        return [
            'filename' => StdSelect::create(),
        ];
    }

    protected function handle($form,$models){
        File::delete(public_path(env('HM_STD_PATH').$form->input('filename')->value()));

        return Note::success('Datei '.$form->input('filename')->value().' wurde gelöscht');
    }
}

I thought, when I add this to my existing dashboard, the task will be done, but the dashboard shows "Oops".

So I think I'm doing something wrong... How can I sove this?

Below the code of the dashboard:

<?php

namespace App\KV\Dashboard\Dashboards;

use App\KV\Dashboard\Tables\StdFileList;
use koolreport\dashboard\containers\Html;
use koolreport\dashboard\containers\Panel;
use koolreport\dashboard\containers\Row;
use koolreport\dashboard\inputs\FileUploader;

class StdBoard extends \koolreport\dashboard\Dashboard
{
    protected function widgets()
    {
       return [
           Html::h2('Heilmittel: STD-Datei-Verarbeitung'),
           Html::hr(),
           Row::create()->sub([
              StdFileList::create(),
              Panel::create()->header('STD-Verwaltung')->type('primary')->sub([
                  Html::h5('STD-Datei hochladen'),
                  FileUploader::create('std_uploader')
                    ->type('primary')
                    ->accept(["std"])
                    ->saveToFolder(public_path(env('HM_STD_PATH')))
                    ->fileName(function($name,$ext){
                      return strtoupper($name).".".$ext;
                  })
                  ->resolveValue(function($file){
                      return $file["name"];
                  })
                  ->fileNotAllowedError("Dateityp nicht erlaubt.")
                  ->fileSizeLmitError("Datei ist zu groß!")
                  ->unknownError("So mysterious")
                  ->noFileError("Keine Datei ausgewählt!")
                  ->noFileSelectedText("Keine Datei ausgewählt!")
                  ->selectFileText("STD-Datei auswählen.."),
                  Html::hr(),
                  Html::p('Die Berechnung kann nur mit einer gültigen STD-Datei erfolgen.'),
                  Html::p('Links die Liste der breits vorhandenen Dateien.'),
                  Html::hr(),
                  Html::h5('STD-Datei löschen'),
                  HmStdDelete::create(), // This is the row making the board oopsing...

                  ]),

           ]),
         
       ];
    }
}

And for being complete the "StdSelect" used in the form:

<?php

namespace App\KV\Dashboard\Elements;

use Illuminate\Support\Facades\File;
use koolreport\dashboard\fields\Number;
use koolreport\dashboard\fields\Text;
use function public_path;

class StdSelect extends \koolreport\dashboard\inputs\Select2
{
    protected function onInit()
    {
        $this
            ->placeHolder('Bitte auswählen!')
            ->cssStyle("margin-left:10px")
            ->cssClass("form-control")
            ->size("lg");
    }

    protected function dataSource()
    {
        $files = File::files(public_path(env('HM_STD_PATH')));
        $array =[];
        foreach($files as $file):
            array_push($array,['id'=>$file->getFilename() ,'filename' => $file->getFilename()]);
        endforeach;
        return $array;
    }

    protected function fields()
    {
        return
        [
        Number::create('id'),
        Text::create('filename'),
        ];
    }

}

Okay, that sounds easier... so where do I have to add this? This is the StdFileList, generated from a directory-listing:

<?php

namespace App\KV\Dashboard\Tables;

use Illuminate\Support\Facades\File;
use koolreport\dashboard\fields\Text;

class StdFileList extends \koolreport\dashboard\widgets\Table
{
    protected function dataSource()
    {
        $files = File::files(public_path(env('HM_STD_PATH')));
        $array =[];
        foreach($files as $file):
            array_push($array,['filename' => $file->getFilename()]);
            endforeach;
        return $array;
    }

    protected function fields()
    {
        Text::create('filename');
    }
}

So I did this in StdFileList to test the Button, but nothing happens: (no button in dashboard)

protected function fields()
    {
        return [
            Text::create('filename'),
            Button::create()
                ->onClick(function($row){
                    return "alert('".$row["filename"]."')";
                })
            ];
    }

I'm getting "oops" .

Okay, this works :) The only thing to be done that's left is reloading the table.

This must be done in actionDelete I think?

Okay, that's easy :)

So this works and thanks for helping me clearing some of the connections between the things in the dashboard-framework.

Have a nice day!

A last question just comes up:

I build this to replace "FileUploader" in the above Dashboard and refreshing "StdFileList" and getting a Note about that:

<?php

namespace App\KV\Dashboard\Inputs;

use koolreport\dashboard\Client;
use koolreport\dashboard\notifications\Note;

class HmStdUploader extends \koolreport\dashboard\inputs\FileUploader
{

    protected function actionUpload($request, $response)
    {
        Client::widget("StdFileList")->action("change");
        return Note::success('Datei hochgeladen');
    }
}

I also added to "StdFileList"

 protected function actionChange($request,$response){
        $this->update();
        return Note::success('Tabelle aktualisiert');
    }

But now the file doesn't upload and the Upload field stuck in action. Which detail is missing?

Thanks again, Peter

Good Morning!

Aah... okay. The code works :)
It works better if you eliminate the "!", because errorMessage() must be null, when everything is okay. ;-)

Thanks for your and have a nice day!
