Errors upon pdf creation and HTML from CF7 textarea not sanitized

  • Hello,
    I’ve found lots of PHP notices in my debug.log, but pdf is created and looks quite good. The real problem is, that if data from CF7 textarea is HTML it is handled correctly in CF7 emails, but affects pdf creation. You can put a code there and it can ruin pdf output.
    Log below:

    Because no one answers.
    To repair textareas handling I’ve changed:
    $value = htmlspecialchars($value); on line 194 in \generate-pdf-using-contact-form-7\inc\frontclass.cf7-pdf-generation.front.action.php

    Hi @elkurczako

    apologize for delayed reply and thanks for your patience and sharing your thought and solution.

    We are checking with this and if it’s works fine and we make it better then we will add it in our next version.

    Also will check with that PHP notice, but that are comes from MPDF Library, so my be if they update library then we will update in our plugin too.

    Thanks,
    ZealousWeb
