FormField support (name and value available for textinput with Libreoffice compat.)

[sos-productions]

Textbox fields name and value can be retrieved using this code:
$phpWord = \PhpOffice\PhpWord\IOFactory::load($docfile);

    $fields[];
    $sections = $phpWord->getSections();
    foreach ($sections as $key => $value) {
        $sectionElement = $value->getElements();
        $first=true;
        foreach ($sectionElement as $elementKey => $elementValue) {

            
             if($elementValue instanceof \PhpOffice\PhpWord\Element\PreserveText) {
                 
                        $fieldDef=$elementValue->getText();
                        if(count($fieldDef)==2) {
                            array_unshift($fieldDef,"");
                        }
                        /**
                         * array (size=3)
                            0 => string '[1=Falun Dafa is Good]' 
                            1 => string '{FORMTEXT}' 
                            2 => string 'SayToTheWorldField=Falun Dafa est Bon'
                         */
                       list($sos_orig_text,$DATATYPE,$sos_trad_text)=  $fieldDef;
                       if(trim($DATATYPE,'{ }')== 'FORMTEXT') {
                            $field=explode('=',$sos_trad_text."=".trim($sos_orig_text,'[]'));
                            $fields[]=$field;
                       }else {
                           var_dump($elementValue->getText());
                           var_dump("Unsupported field Type $DATATYPE :");
                           die("stop");
                       }
             }

echo "

";

echo(htmlentities(implode("\n",$fields)));

echo "
