Laravel - Popular a list with files in a directory

Question

I would like to popular a list on a Blade page in the Laravel Framework. I tried to do

<select id="idSelMinhaLista">
    @if(isset($arrayRemessa))
        @for($i=0;$i < count($arrayRemessa);$i++)
            <option>{{$arrayRemessa[$i]}}</option>
        @endfor
    @endif
</select>

The $arrayRemessa variable is fed by a call to a PHP method, which in turn makes a Return by calling the View Blade that shows the select above. The method makes:

public function listarArquivosRemessa(){

    $arrayRemessa = [];
    $filesInFolder = \File::files('assets/remessa');

    foreach($filesInFolder as $path)
    {
        $arrayRemessa[] = pathinfo($path);
    }
    return view ("PesquisaView")->with("arrayRemessa",$arrayRemessa);
}//listarArquivosRemessa

My problem is that I have the error below:

htmlspecialchars() expects Parameter 1 to be string, array Given

My 'coward' exit was to use jQuery. This is:

Na View, simply:

<select id="idSelItauArquivosRemessa">
</select>
<button type="button" id="idBtnRefreshListaRemessaItau">Refresh</button>

In the jQuery:

jQuery("#idBtnRefreshListaRemessa").click(function (){
    var objSel=jQuery("#idSelItauArquivosRemessa");
    objSel.empty();
    var concatena='<option value="0" title="0"></option>';
        jQuery.get("itauRefreshArquivosRemessa",function(retorno){
            for(i=0;i < retorno.length;i++){
                concatena=concatena+'<option value="'+retorno[i].basename+' "title="'+retorno[i].basename+'">'+retorno[i].basename+'</option>';
            }//for
         objSel.append(concatena);
        });//get
});//idBtnRefreshListaRemessa

On Route: Route::get('itauRefreshAquivosRemessa','Despesascontroller@listararvosremessaitau');

In the method:

public function listarArquivosRemessaItau(){
    $arrayRemessa = array_map('pathinfo', \File::files('assets/remessa'));
    return $arrayRemessa;
}//listarArquivosRemessaItau

That’s because by putting something between {{ }}, Laravel will try to make an escape from whatever is there and only possible escape strings.

In this case, the content of $arrayRemessa[$i] is a array and so is bursting this mistake.

Understand that the return of path_info is a array associative, that is to say, each position in $arrayRemessa contains an associative array with the data from that folder.

As Keys of this array sane dirname, basename, extension and filename.

You will need to choose which one you want to show on view, for example:

@for($i=0;$i < count($arrayRemessa);$i++)
    <option>{{ $arrayRemessa[$i]['filename'] }}</option>
@endfor

Also, the code might get a little better:

public function listarArquivosRemessa()
{    
    $arrayRemessa = array_map('pathinfo', \File::files('assets/remessa'));
    $arrayView = array_pluck($arrayRemessa, 'dirname');
    // (^) Isso vai extrair apenas as keys que você precisa

    return view ("PesquisaView")->with("arrayRemessa", $arrayView);
}

And in the view can stay like this:

@foreach($arrayRemessa as $item)
    <option>{{ $item }}</option>
@endfor
