Good day experts!

I am stuck on a problem.
This is my function.php

 function tbl_questions() {

    global $mysqlhost, $mysqluser, $mysqlpwd, $mysqldb;







$connection=mysqli_connect($mysqlhost, $mysqluser, $mysqlpwd) or die ("Verbindungsversuch fehlgeschlagen");

        mysqli_select_db($connection, $mysqldb) or die("Konnte die Datenbank nicht waehlen.");

        $sql_tbl_questions = "SELECT * FROM `questions` where istAktiv='1'";

        $quest_query = mysqli_query($connection, $sql_tbl_questions) or die("Anfrage nicht erfolgreich");



    $i = 0;



    while ($question = mysqli_fetch_array($quest_query)) {

        $i++;

        echo '<tr>';

        echo '<th>'.$i.'</th>';

        echo '<th>'.$question['question'].'</th>';

        echo '<th class="text-center"><input type="radio" name="'.$question['dimension'].'_question_'.$question['id'].'" value="0" required></th>';

        echo '<th class="text-center"><input type="radio" name="'.$question['dimension'].'_question_'.$question['id'].'" value="2.5"></th>';

        echo '<th class="text-center"><input type="radio" name="'.$question['dimension'].'_question_'.$question['id'].'" value="5"></th>';

        echo '<th class="text-center"><input type="radio" name="'.$question['dimension'].'_question_'.$question['id'].'" value="7.5"></th>';

        echo '<th class="text-center"><input type="radio" name="'.$question['dimension'].'_question_'.$question['id'].'" value="10"></th>';

        echo '</tr>';

        $dimensions = $question['dimension'];

    }

    echo '<tr>';

        echo '<th></th>';

        echo '<th>Kommentar/Ihre Anmerkung</th>';

        echo '<th class="text-center" colspan=5><textarea rows=3 cols=50 name="Kommentar"></textarea></th>';

        echo '</tr>';



    echo '<input type="hidden" name="gesamt" value="'.$i.'">';

    echo '<input type="hidden" name="dimensions" value="'.$dimensions.'">';

    echo '<input type="hidden" name="size" value="'.$_POST['size'].'">';    

    echo '<input type="hidden" name="branche" value="'.$_POST['branche'].'">';

    //echo $_POST['size'];

    //echo $_POST['branche'];   

    }`

That function.php is saving data from an questionaire which is containing values.
My problem is as easy as complex. I am moving through this questionaire through an javascript:

function senden(goBack){



	if(goBack==0)

	{

		document.getElementById('page').value++;

		if(	document.getElementById('page').value >9){

			document.getElementById('submitForm').action='auswertung.php';

			

		}

		document.getElementById('submitForm').submit();

	}

	else

	{

		document.getElementById('page').value--;

		if(	document.getElementById('page').value <1){

			document.getElementById('submitForm').action='branche.php';

			

		}

		document.getElementById('submitForm').submit();

	}



}

And of course some html for the buttons:

  <input type="hidden" id="page" name="page" value="<?php echo $page; ?>" />

  <button type="button" id="doubleButtons" class="btn btn-default" onclick="senden(1)">Zurück</button>

  <button type="button" id="doubleButtons" class="btn btn-default" onclick="senden(0)"><?php echo $page==9?"FDC Auswerten":"Weiter";?></button>

The questionnaire got those radio buttons which i am talking about, a button for next and a button for back.

My problem is : If i am filling my questionnaire and press the back button, the filled stuff is gone!
So my idea was to save everything into an array, but can you give me a hint how i have to do it?

I hope my question is quite clear, if not, please excuse me and let me know!

try using history.back function?

<button onclick="history.back()">Back</button>
