PHP update of Query with Form - php

Question

Here is code I use to update data of one row of form table. This is the code I wanna change.
The change should allows me update not only one row of the shown table but every line:
if(isset($_POST['update'])){
$UpraveneQuery = "UPDATE uctovnictvo SET meno='$_POST[meno]', datum='$_POST[datum]', obchod='$_POST[obchod]', druh='$_POST[druh]', cena='$_POST[cena]', Poznamka='$_POST[poznamka]' WHERE uct_id='$_POST[hidden]' "; //--------------
mysql_query($UpraveneQuery, $con);
};
here are data with which I work for this particular case:
$sql = "SELECT * FROM uctovnictvo WHERE meno IN ('" . implode('\', \'', $option_meno) . "') AND obchod IN ('" . implode('\', \'', $option_obchod) . "') AND druh IN ('" . implode('\', \'', $option_druh) . "') AND datum BETWEEN '$date_start' AND '$date_end' ORDER BY $order";
$mojeData = mysql_query($sql,$con) or die($sql."<br/><br/> Chyba 1 je:".mysql_error());//run query a ulozit to premennej
here is code which generates form table which allows me to change content of it. Every row of the table has its own button for deleting or updating the row.
NOW
When I clik on ulozit zmenu (update) on certain row it allows me to post values of that one row and update variables of the row (query).
PLAN
I dont want to have button ulozit zmenu (update) next to every row of the table but only one butto which will post values of every shown row of the table.
while($zaznam = mysql_fetch_array($mojeData))
{
echo "<form action=index-5.php method=post>";
echo "<tr>";
echo "<td>" . "<input type=text name='meno[]' value='" . $zaznam['meno'] . "'>" . "</td>";
echo "<td>" . "<input type=date name='datum[]' value='" . $zaznam['datum'] . "'>" . "</td>";
echo "<td>" . "<input type=text name='obchod[]' value='" . $zaznam['obchod'] . "'>" . "</td>";
echo "<td>" . "<input type=text name='druh[]' value='" . $zaznam['druh'] . "'>" . "</td>";
echo "<td>" . "<input step=any type='number[]' name=cena value='" . $zaznam['cena'] . "'>" . "</td>";
echo "<td>" . "<input type=text name='poznamka[]' value='" . $zaznam['poznamka'] . "'>" . "</td>";
echo "<td>" . "<input type=submit name='update[]' value='ulozit zmenu'" . ">" . "</td>";[]
echo "<td>" . "<input type=submit name='zmazat[]' value='zmazat'" . ">" . "</td>";
echo "</tr>";
