Hello again,
I've been trying to implement what was said, but it just doesn't work here..
For the moment I go for the suggestion with a Hidden field in the form,
because that looks the most simple one, and I'm only using this application
at home, it's only for me and not for anybody else..
I'm testing this in IE6 with IIS.
Loading the page goes ok, and the pageno echoes as '1'.
Then I hit submit, the pageno echoes as blank and I get the following
notice: Notice: Undefined index: pageno in
c:\\inetpub\\wwwroot\\picdata\\de2.php on line 39
Here's the code:
<html>
<head>
<title>Picture data entry</title>
</head>
<body>
<div id="container">
<?php
/*initialize pageno */
/* if there is a pageno then it must be one higher then the last time */
if (isset($_GET['pageno']))
{
$pageno = $_GET['pageno'];
$pageno = $pageno++;
}
else
{
$pageno = 1;
}
echo "pageno :" . $pageno;
?>
<p>
<hr align = "left">
<table>
<tr>
<td align = "center" >
<img border = "0" src = "images/01bc11.jpg ">
</td>
<td>
<form method="GET" action ="de2.php?pageno=$pageno">
<input type="text" name="pictureid" value="pictureid" READONLY>
Picture ID <BR>
<input type="text" name="year" value="year" READONLY> Year <BR>
<input type="hidden" name="pageno" value="<?php echo $_GET['pageno'];
?>">
<p>
<input type="submit" name="submit" value="Submit">
</form>
</td>
</tr>
</table>
<hr align = "left">
</div>
</body>
</html>
Thanks for any suggestion...
Marcel
