As you've found, history.back() is not foolproof. And what if they have
javascript disabled?
It's harder, but put the cancel button in a form. In that form have the
values as hidden fields, i.e.
<form action="/entrypage.php" method="post">
<input type=hidden name="value1" value="<?php echo $value1;%>
<input type=hidden name="value2" value="<?php echo $value2;%>
<input type=hidden name="value3" value="<?php echo $value3;%>
<input type=submit value="Cancel">
</form>
Then on entrypage.php use:
<?php
$value1 = isset($_POST['value1']) ? $_POST['value1'] : "";
$value2 = isset($_POST['value2']) ? $_POST['value2'] : "";
$value3 = isset($_POST['value3']) ? $_POST['value3'] : "";
%>
....
<input type=text name="value1" value="<?php echo $value1;%>">
<input type=text name="value2" value="<?php echo $value2;%>">
<input type=text name="value3" value="<?php echo $value3;%>">
Of course, loops and arrays can make the coding simpler.
