Question : PHP/XHTML file upload not working with ie or firefox
|
|
|
|
|
I have been asked to create a form that allows users to upload a picture. It works great in Safari, Chrome, and Opera. Fails in ie and firefox. The browser itself is refusing to send anything.
Here is my code:
<?php
session_start();
echo "<?xml version = '1.0' encoding = 'utf-8' ?>";
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<!--
Picture upload Page
-->
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head profile = 'http://www.w3.org/2005/10/profile'>
<title>Commando Pic Upload</title>
<link rel = 'icon' type = 'image/png' href = '../img/cc.png' />
<?php
if (isset ($_SESSION['special'])) {
$uploaded = false;
$stored = false;
$error = "";
ini_set ("max_input_time", 300);
if ($_POST['submit']) {
if ($_FILES['picFile']['error'] > 0) {
$error = "Error Code: " . $_FILES['picFile']['error'] . "<br />\n";
$error .= "Something unusual happened during the upload. The image never arrived.<br />\n";
}
else if ($_FILES['picFile']['size'] > (2048 * 1024)) {
$error = "Your file is too big. (" . ($_FILES['picFile']['size'] / 1024) . "KB)<br />\n";
$error .= "The limit is 2MB (2048KB).<br />\n";
}
else if ($_FILES['picFile']['type'] == "image/jpeg"
|| $_FILES['picFile']['type'] == "image/pjpeg"
|| $_FILES['picFile']['type'] == "image/jpg") {
$srctemp = imagecreatefromjpeg ($_FILES['picFile']['tmp_name']);
$uploaded = true;
}
else if ($_FILES['picFile']['type'] == "image/gif") {
$srctemp = imagecreatefromgif ($_FILES['picFile']['tmp_name']);
$uploaded = true;
}
else if ($_FILES['picFile']['type'] == "image/png") {
$srctemp = imagecreatefrompng ($_FILES['picFile']['tmp_name']);
$uploaded = true;
}
else {
echo "The file type: '" . $_FILES['picFile']['type'] . "' is not supported.<br />\n";
echo "Please Choose a File that is either .gif, .png or .jpg (jpeg) format.<br />\n";
echo "(Please note: there is an issue with uploading files using internet explorer or firefox.\n";
echo "We are working to resolve these issues. Meanwhile, have you tried a different browser?<br />\n";
echo "<br /><hr noshade /><strong>Debug $_FILES</strong><pre>" . print_r($_FILES,true) . "</pre><hr noshade />\n";
}
}
if ($uploaded) {
$newName = '../lib/files/' . $_SESSION['special'] . '.jpg';
$srcWidth = imagesx ($srctemp);
$srcHeight = imagesy ($srctemp);
if ($srcWidth < 200 || $srcHeight < 385) {
imagejpeg ($srctemp, $newName, 75);
imagedestroy ($srctemp);
$stored = true;
}
else {
$cropHeight = (int) ($srcHeight * .95);
$cropWidth = (int) ($cropHeight * 200 / 385);
$srcX = (int) (($srcWidth - $cropWidth) / 2);
$srcY = (int) (($srcHeight - $cropHeight) / 2);
$dsttemp = imagecreatetruecolor (200, 385);
imagecopyresized ($dsttemp, $srctemp, 0, 0, $srcX, $srcY, 200, 385, $cropWidth, $cropHeight);
imagejpeg ($dsttemp, $newName, 75);
$stored = true;
}
}
if ($stored) {
echo "<meta http-equiv = 'Refresh' content = '0;url=index.php' />\n";
echo "</head>\n<body>\n<div>\nUploaded\n</div>\n";
}
else {
?>
</head>
<body>
<?php
if ($error != "") {
echo "<div>\n$error\n</div>\n";
}
?>
<form method = 'post' action = 'pic_upload.php' enctype = 'multipart'>
<div>
Upload your photo.<br /><br />
It needs to be less than 2MB (2048KB) in size.
The system will automatically crop your photo to 200 x 385 pixels.<br /><br />
If you aren't in the middle of the picture, or your picture is too
high of a resolution, then the results might not be what you want.
If this happens, use some basic picture editing software to crop your photo and try again.<br /><br />
Your picture can be in either .gif, .png or .jpg (jpeg) file format.<br /><br />
<label for = 'picFile'>
File:
</label>
<br />
<input type="hidden" name="MAX_FILE_SIZE" value="30000000" />
<input type = 'file' name = 'picFile' id = 'picFile' />
<br />
<input type = 'submit' name = 'submit' value = 'Upload' />
<br /><br />
(Remember: Your facilitators will be able to see this picture.)
<br /><br />
</div>
</form>
<div>
<a href = 'index.php'>Return to your Card Page.</a>
</div>
<?php
}
}
else {
?>
<div>
<h4>Your session appears to have expired.</h4>
<a href = '../login.php'>Login</a><br />
or<br />
<a href = '../index.php'>Return to Home Page</a>
</div>
<?php
}
?>
</body>
</html>
In ie and firefox, the output looks like:
The file type: '' is not supported.
Please Choose a File that is either .gif, .png or .jpg (jpeg) format.
(Please note: there is an issue with uploading files using internet explorer or firefox. We are working to resolve these issues. Meanwhile, have you tried a different browser?

What happens if your form type is set to
multipart/form-data
rather than just
multipart?
Like so <form method = 'post' action = 'pic_upload.php' enctype = 'multipart/form-data'>
