Fix for: TCPDF ERROR: Some data has already been output, can’t send PDF file

  • Hello! On one of our websites, the PDF export of a job posting didn’t work.

    Notice: Undefined variable: content in /SERVERPATH/wp-content/plugins/job-postings/include/class-pdf-export.php on line 406
    TCPDF ERROR: Some data has already been output, can’t send PDF file

    We found a fix (mentioned here: https://stackoverflow.com/questions/16011050/tcpdf-error-some-data-has-already-been-output-cant-send-pdf-file) and would like to share it.

    Fix:
    /wp-content/plugins/job-postings/include/class-pdf-export.pdf

    ~ Line 302:
    $epdf = $pdf->Output($file_name , 'D');

    Change to:
    ob_end_clean();
    $epdf = $pdf->Output($file_name , 'D');

    Could this be added to the plugin by default?
