Issues with missing caching and image solutions
I have a php page with some forms used to upload images. Each form loads one image. Uploaded images replace images still uploaded to the page.
Here's a snippet:
<?php
// NO CACHING CODE
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
// FORM SUBMIT CODE
if (isset($_POST['submit_img1'])) {
// used for some photo manipulation and checks
require_once('WideImage/WideImage.php');
//... some code ...
unlink("path/" . $img1);
$img_name = "path/" . $img1;
$wideImage->saveToFile($img_name, 80);
// ... some code ...
}
// PRINT IMAGE IN THE PAGE
echo '<p><img src="path/' . $img1 . '" width="100" height="100" class="prof_img" /></p>';
?>
//FORM FOR CHANGE THE IMAGE
<form id="form_img1" name="form_img1" method="post" onSubmit="return checkFormImg1()"
action="" enctype="multipart/form-data">
<input class="prof_input" type="file" name="img1" id="img1" />
<input name="submit_img1" type="submit" class="prof_submit" value="Inserisci Immagine 1"
/>
</form>
The problem is that on reboot (after clicking submit button) old images are displayed. But the new images were loaded correctly, replacing the old ones.
Excuse my english.
