dompdf generates a pdf empty / corrupted

I have a problem with dompdf. I'm trying to generate a PDF file through the values of a form. A user enters the website, fills out the fields and clicks submit. In my email I must attach a PDF with all the form values. I was able to integrate it into my code, but there is something wrong. To submit, I get the mail with the PDF, but it is damaged. (Of 0BYTE.)

The code I've entered in includes / ajax.php. This is the code:

      // Generate PDF here
      require_once("../dompdf/dompdf_config.inc.php");
	  spl_autoload_register('DOMPDF_autoload');
        
      $dompdf = new DOMPDF(); 
      $dompdf->load_html($message); 
      $dompdf->render(); 
      $pdf_content = $dompdf->output();
      file_put_contents('../dompdf/ordine.pdf',$pdfoutput);

data users write in the form are in $message

this is my ajax.php

Solution

  • Try this

    // Generate PDF here
  require_once("../dompdf/dompdf_config.inc.php");
  spl_autoload_register('DOMPDF_autoload');

  $dompdf = new DOMPDF(); 
  $dompdf->load_html($message); 
  $dompdf->render(); 
  $pdf_content = $dompdf->output();
  file_put_contents('../dompdf/ordine.pdf',$pdf_content);  //there was a typo here...

    You pdf was correctly 0 bytes because you write an undefined variable to it.
