If I read your rather terse message correctly, you are looking for a way
to provide error responses to the user without losing his/her input.
One way would be to add JS to your page, but you want it done with php.
To do that all you have to do is be sure to capture all the input fields
before beginning your editing and then to be sure to use those captured
values (in their php vars) as the value clause of the html tags.
When you are receiving the POST data:
$fld1 = $_POST['fld1'];
$fld2 = $_POST['fld2'];
.
.
.
When you are editing use a var to hold your error message:
$errmsg = '';
if ($fld1 == '')
{
$errmsg .= "You must enter a value for ....";
}
if ($fld2 > 0 && $fld2 < 10)
{
$errmsg .= "You must enter a value between 1 and 9 for ....";
}
When you prepare the output page with tags:
echo $errmsg;
echo "<form.....>";
echo "<input type='text' name='fld1' value='$fld1'>";
echo "<input type='text' name='fld2' value='$fld2'>";
.
.
.
Hope this is what you are looking for, altho if you are already using
php, you should already be doing this....
