Error including Composer (Class not found)

Question

I’m getting the following error:

Fatal error: Class 'wkhtmltopdf Pdf' not found in /Applications/XAMPP/xamppfiles/htdocs/common/class/Prepagoconsulta.php on line 480

Excerpt from the code:

use wkhtmltopdf\Pdf;

class PrePagoConsulta extends Query
{
    public function gerarPDF($html, $nomeArquivo){

        $pdf = new Pdf($html); // * Linha 480

        if (!$pdf->saveAs($_SERVER['DOCUMENT_ROOT'].'/upload/consultas-pre/'.$nomeArquivo.'.pdf')) {
            echo $pdf->getError();
        }
    }
}

And the folder structure is as follows:

In the autoload_psr4.php, I’m setting it this way:

return array(
    'wkhtmltopdf\\' => array($vendorDir.'/wkhtmltopdf/src')
);

How can I correct the error? Where am I missing? hehe

Answer 1

This scheme is strange, because when it installs it stays in the folder vendor, unless you have set up lib, it seems to me that you did not use Composer to install the packages, but tried to install them manually.

If the package you are using is the https://github.com/mikehaertl/phpwkhtmltopdf, then you installed something wrong, because the package name is not wkhtmltopdf, but yes phpwkhtmltopdf (prefixed "php"), so the right thing should be:

use mikehaertl\wkhtmlto\Pdf;

class PrePagoConsulta extends Query
{
    public function gerarPDF($html, $nomeArquivo){

        $pdf = new Pdf($html); // * Linha 480

        if (!$pdf->saveAs($_SERVER['DOCUMENT_ROOT'].'/upload/consultas-pre/'.$nomeArquivo.'.pdf')) {
            echo $pdf->getError();
        }
    }
}

However if you installed it manually I really recommend that you review it and try to install it via command line (which is exactly what Composer does), do something like:

cd pastadomeuprojeto
composer require mikehaertl/phpwkhtmltopdf

Ready it will do everything manually, so import:

use mikehaertl\wkhtmlto\Pdf;
