Need Fix | PHP Warning | DOMDocument

Update:

Found the code snippet (see below). Based on the above warnings, any idea how to fix it?

Thank you!

add_filter( 'gform_submit_button', 'gf_change_submit_button_text', 10, 2 );
  function gf_change_submit_button_text( $button, $form ) {
    $dom = new DOMDocument();
    $dom->loadHTML( '<xml encoding="utf-8" ?>' . $button );
    $input = $dom->getElementsByTagName( 'input' )->item(0);
    $onclick = $input->getAttribute( 'onclick' );
    $onclick .= " this.value='Sending...'"; // Change button text when clicked.
    $input->setAttribute( 'onclick', $onclick );
    return $dom->saveHtml( $input );
}

From the errors, it sounds like the issue isn’t with your snippet, but with the XML you’re getting it to parse.

Given that you’re just trying to augment the onclick attribute of a button, perhaps you could achieve the same thing with some basic JavaScript elsewhere on the page?

Hi @bungeshea,

Thanks for the review and suggestion. Although I’m gettting the above PHP warning, everything is working on our site and not getting any console errors. So … not sure what the implications of the warning are at this time.

Perhaps I just need to review and/or change the code line below and see if that helps.

$dom->loadHTML( '<xml encoding="utf-8" ?>' . $button );

Again, thank you.

Issue Solved:

Warning caused by a missing “?” in front of xml.

Above line should be:

$dom->loadHTML( '<?xml encoding="utf-8" ?>' . $button );

Cheers!
