Yii2 - Multiples files download from Folder

I have a issue with Yii2 and multiple download. I'm using Fpdf to generate PDF and save them on a folder. This is ok, but when I try to download all of them from that folder, he just return me one file, the first one:

 for($x = 1; $x <= $vlt; $x++){
        if (file_exists($tempPath.'Client'.$x.'.pdf')) {
            Yii::$app->response->sendFile($tempPath.'Client'.$x.'.pdf');
        }
    }

I don´t understand why this happen.

Thank you.

This aint happening friend, You should zip all files and then download them rather than trying to download them like this SEE WHY.

You should instead zip and download all the files, you can use ZipArchive class to achieve this, change your above code so that all your zip files are added into a single ZIP and then download that zip file.

Just remember that

1) The below script uses a temp folder inside your project root with the name tmp to create the zip file and download, adjust your path accordingly for $zipname if you want to use some other directory.

2) You should provide the complete path in the $tempPath so that the files are added successfully to the zip file.

    //set zip file name for download
    $zipFilename = md5('file-' . time()) . '.zip';

    //zip file name with path
    $zipPath = Yii::$app->basePath . DIRECTORY_SEPARATOR . '..' . DIRECTORY_SEPARATOR . 'tmp' . DIRECTORY_SEPARATOR . $zipFilename;

    //start adding the files into the zip archive
    $zip = new \ZipArchive();

    //open zip archive 
    $zip->open($zipPath, \ZipArchive::CREATE | ZipArchive::OVERWRITE);

    for ($x = 1; $x <= $vlt; $x++) {
        if (file_exists($tempPath . 'Client' . $x . '.pdf')) {
            $zip->addFile(realpath($tempPath . DIRECTORY_SEPARATOR . 'Client' . $x . '.pdf'), 'Client' . $x . '.pdf');
        }
    }
    

    //close the zip file
    $zip->close();

    //return zip archive name without path
    Yii::$app->response->sendFile($zipPath);
