How to fill out a form using PHP and XPatch - php

Question

I have this HTML code and I would like it to be automatically filled with parameters taken from the database/table:
Array
(
[0] => Array
(
[id] => 35
[nr_wyceny] => W/8/01041122/2021
[nazwa_firmy] => Test
[adres_firmy] => testowy
[kraj_firmy] => polska
[telefon_firmy] => 79280xxxx
[osoba_firmy] => ja
[email_firmy] => pow#d.pl
[data_inwestycji] => 12/12/2020
[wycena_wstepna] =>
[wycena_zrzutem] => on
[jakosc_niska] => on
[jakosc_srednia] =>
[jakosc_wysoka] =>
[wygoda_mala] => on
[wygoda_srednia] =>
[wygoda_maksymalna] =>
[cena_niska] => on
[cena_srednia] =>
[cena_wysoka] =>
[wydajnosc_niska] =>
[wydajnosc_srednia] =>
[wydajnosc_wysoka] => on
[srodki_wlasne] => on
[finansowanie_zewnetrzne] =>
[finansowanie_niepodane] =>
[dzialalnosc_uslugowa] => on
... //more data
The point is that I download an array with the names and values of input fields from the database, if there is a checkbox then the value is on or null if there is input type text then it should have a value, but I don't know how to fill in the form using XPatch - possibly some other method to fill it this form, without rewriting the code. I have a lot of values to fill in and would like to do it automatically. i know how to do it the other way, but i would like to use xpatch and a DOM parser
<form action="/xxxxxx.php" method="post" id="xForm" >
<div class="tabela">
<div id="sekcja1" class="sekcja">
<div class="headerx"><p><b>Dane klienta</b></p></div>
<p>Nazwa firmy: <input class="xForm" type="text" name="nazwa_firmy" value=""/>
<p>Adres: <input class="xForm" type="text" name="adres_firmy" value=""/>
<p>Kraj: <input class="xForm" type="text" name="kraj_firmy" value=""/>
<p>Telefon kontaktowy: <input class="xForm" type="text" name="telefon_firmy" value=""/>
<p>Osoba do kontaktu: <input class="xForm" type="text" name="osoba_firmy" value="" />
<p>Email: <input class="xForm" type="text" name="email_firmy" value=""/>
<p><b>Planowany termin realizacji inwestycji: <input class="xForm" type="text" name="data_inwestycji" id="datepicker" value=""/></b>
</div>
<div id="sekcja2" class="sekcja">
<div class="headerx"><p><b>Dane na temat formy preferowanej wyceny:</b></p></div>
<p>Wstępna wycena <input class="xForm" type="checkbox" name="wycena_wstepna" checked="" />
<p>Wycena docelowa z rzutem urządzeń <input class="xForm" type="checkbox" name="wycena_zrzutem" checked="" />
<br />
<!---// More form data more input fields //--->
</form>
My PHP code is:
<?php
$url = file_get_contents('/wycena.html');
$url = mb_convert_encoding($url, 'utf-8', mb_detect_encoding($url));
$url = mb_convert_encoding($url, 'html-entities', 'utf-8');
$dom = new DOMDocument();
$dom->loadHTML($url);
$xpath = new DOMXpath($dom);
$html = $dom->saveHTML();
$dom->loadHTML($html);
// in this case i have fill only one field of input by name "nazwa_firmy" //and value "testtest" only for testing
//=======================================================
$key="nazwa_firmy"; //name of input element - test data
$val="testest"; //value of input element - test data
//=======================================================
$item = $xpath->query('//input[#name = "'.$key.'"]/#type');
if($item[0]->nodeValue=="text"){
$itemx = $xpath->query('//input[#name = "'.$key.'"]/#value');
}
if($item[0]->nodeValue=="checkbox"){
$itemx = $xpath->query('//input[#name = "'.$key.'"]/#checked');
}
$itemx[0]->nodeValue = $val;
echo $html = $dom->saveHTML();
?>
Why is it not possible to fill in the form in this way, is there any method to fill it in?

If you aleady have $array containing the values, just echo them inside the value attrubute of the form: -
<p>Nazwa firmy: <input class="xForm" type="text" name="nazwa_firmy" value="<?= $array [nazwa_firmy] ?>"/>
<p>Adres: <input class="xForm" type="text" name="adres_firmy" value="<?= $array [adres_firmy] ?>"/>
<p>Kraj: <input class="xForm" type="text" name="kraj_firmy" value="<?= $array [kraj_firmy] ?>"/>
<p>Telefon kontaktowy: <input class="xForm" type="text" name="telefon_firmy" value="<?= $array [telefon_firmy] ?>"/>
<p>Osoba do kontaktu: <input class="xForm" type="text" name="osoba_firmy" value="<?= $array [osoba_firmy] ?>" />
<p>Email: <input class="xForm" type="text" name="email_firmy" value="<?= $array [email_firmy] ?>"/>
<p><b>Planowany termin realizacji inwestycji: <input class="xForm" type="text" name="data_inwestycji" id="datepicker" value="<?= $array [data_inwestycji] ?>"/></b>
</div>
