Hi all,

this script works fine when I submit the form with FF but when I submit it with IE it instantly returns errors for phpGD, and I have no idea why. I just spent 4 hours getting the script to work so this has really annoyed me. Im guessing its some stupid mistake in the form but I can't spot it.

Quote:
<center><font size="2" face="verdana">
<h2>Forum Image Upload</h2><p>

Use this form to upload an image for use on the forum. Max size 5000KB. BBCode will be provided when the upload completes.<p>

<b>This form doesnt seem to work for IE users, sorry. Im working to fix it ASAP.</b><p>

<form enctype="multipart/form-data" action="index.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="5000000">
Choose a file to upload: <input name="imagefile" type="file">
<input type="submit" value="Upload File">
</form><p>

Allowed file extensions: jpg, jpeg, JPG, JPEG, png, PNG.<p>


<?php

if($_POST){

// Get the details of "imagefile"
$filename = $_FILES['imagefile']['name'];
$temporary_name = $_FILES['imagefile']['tmp_name'];
$mimetype = $_FILES['imagefile']['type'];
$filesize = $_FILES['imagefile']['size'];




$ok = 0;
$allowed_ext = "jpg, jpeg, JPG, JPEG, png, PNG, ";

$extension = pathinfo($filename);
$extension = $extension[extension];
$allowed_paths = explode(", ", $allowed_ext);
for($i = 0; $i < count($allowed_paths); $i++) {
if ($allowed_paths[$i] == "$extension") {
$ok = "1";
}
}

if($ok == "0") {
echo("<font color=red>This type of file is not allowed to be uploaded.<p>");
}


else{


//Open the image using the imagecreatefrom..() command based on the MIME type.
switch($mimetype) {
case "image/jpg":
case "image/jpeg":
$i = imagecreatefromjpeg($temporary_name);
break;
case "image/gif":
$i = imagecreatefromgif($temporary_name);
break;
case "image/png":
$i = imagecreatefrompng($temporary_name);
break;
}

//Delete the uploaded file
unlink($temporary_name);

$rand=date(U);
$savename=$rand.".or.".$filename;

//Save a copy of the original
imagejpeg($i,$savename,75);

//Specify the size of the thumbnail
$dest_x = 500;
$dest_y = 500;

//Is the original bigger than the thumbnail dimensions?
if (imagesx($i) > $dest_x or imagesy($i) > $dest_y) {
//Is the width of the original bigger than the height?
if (imagesx($i) >= imagesy($i)) {
$thumb_x = $dest_x;
$thumb_y = imagesy($i)*($dest_x/imagesx($i));
} else {
$thumb_x = imagesx($i)*($dest_y/imagesy($i));
$thumb_y = $dest_y;
}
} else {
//Using the original dimensions
$thumb_x = imagesx($i);
$thumb_y = imagesy($i);
}

//Generate a new image at the size of the thumbnail
$thumb = imagecreatetruecolor($thumb_x,$thumb_y);

//Copy the original image data to it using resampling
imagecopyresampled($thumb, $i ,0, 0, 0, 0, $thumb_x, $thumb_y, imagesx($i), imagesy($i));

$savename2=$rand.".th.".$filename;
//Save the thumbnail
imagejpeg($thumb,$savename2, 75);


echo('
<script>
function highlight(field) {
field.focus();
field.select();
}

</script>
<font color=green>The file <b>'.$filename.'</b> has been uploaded.<p>
BBCode: <input type="text" value="[url=http://www.betaarchive.co.uk/imageupload/'.$savename.'][img]http://www.betaarchive.co.uk/imageupload/'.$savename2.'[/img][/url]" readonly size="100" onClick="highlight(this);">

');

}

}

?>



Thanks in advance.

The only thing that I can think of is that the mime type set in IE is different, and when you use the switch statement it is not matching the mime types

Code:
switch( strtolower($mimetype)) {
    case "image/jpg":
    case "image/jpeg":
        $i = imagecreatefromjpeg($temporary_name);
        break;
    case "image/gif":
        $i = imagecreatefromgif($temporary_name);
        break;
    case "image/png":
        $i = imagecreatefrompng($temporary_name);
        break;
    default: //If nothing matches
        print $mimetype; //print out what the var is
}


Does the code above work?

Wait a minute, IE handles the Jpeg Mimetype differently. Its pjpeg in IE. DOH! Ill try adding that in and see if it works.

EDIT: Now it works! Such a stupid thing. Trust IE to be different. Thanks for the help roganty, you made me realise what was wrong cutting out that code.
