Guys, not sure if this is a PHP problem or a more general HTML problem,
but...
I've written a small test script (see below), basically, which allows the
user to rotate an image by 90degrees.
When I press the button, the page reloads having rotated the image, but the
old image is still displayed. (I know it's done it if I load up another
browser window)
Pressing refresh does cause the image to reload.
Any ideas???
<?php
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in
the past
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // always
modified
header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache"); // HTTP/1.0
?>
<head>
<TITLE>Yama!</TITLE>
</head>
<body>
<p />
<?php
if($submit == "Rotate 90")
{
$output=`mogrify -rotate 90 pictures/028_25.jpg`;
echo "$output<p />";
}
$submit=" ";
echo "new value of submit=$submit";
?>
<form name="form1" action="<?php echo($PHP_SELF) ?>" method="post">
<input type="submit" name="submit" value="Rotate 90">
</form>
<p />
<img src = pictures/028_25.jpg>
</body>
</html>
Regards & thanks in advance
