I have a conundrum of sorts, I want to have a dual purpose form, the form is only ever going to be on my computer so none of the usual security needs will be present, so I found a AJAX script on the W3C site and I modified a little.
[code=html]<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml”>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=iso-8859-1″ />
<title>Untitled Document</title>
<script>
function upload() {
var client = new XMLHttpRequest();
var file = document.getElementById(“contentSelect”);
/* Create a FormData instance */
var formData = new FormData();
/* Add the file */
formData.append(“upload”, file.files[0]);
client.open(“post”, “upload.php”, true);
client.setRequestHeader(“Content-Type”, “multipart/form-data”);
/* Check the response status */
client.onreadystatechange = function(){
if(client.readyState == 4 && client.status == 200)
alert(client.statusText + ” ” + client.responseText);
}
client.send(formData); /* Send to server */
}
</script>
</head>
<body>
<form name=”uploadfile” action=”javascript:;” method=”POST” enctype=”multipart/form-data” onsubmit=”return false;”>
<input type=”hidden” name=”POST_MAX_SIZE” value=”99999999″ />
<input type=”file” id=”contentSelect” name=”contentSelect” />
<input type=”submit” name=”submit” value=”Submit” onclick=”upload()”/>
</form>
</body>
</html>
The form itself reports back that everything is OK, the file was not showing in the directory for the upload so I made the PHP script return the upload name but instead of getting the filename back, I get an error message.
This message reads…
[CODE]OK<br />
<b>Warning<b />: Missing boundary in multipart/form-data POST data in <!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01//EN”
“http://www.w3.org/TR/html4/strict.dtd”>
<html lang=”en”>
<head>
<meta http-equiv=”content-type” content=”text/html; charset=iso-8859-1″>
<title>Upload error</title>
</head>
<body>
<div id=”Upload”>
<h1>Upload failure</h1>
<p>An error has occured:
<span class=”red”> the upload form is needed</span>
The upload form is reloading</p>
</div>
</html>
Well the upload form is being used and the upload form without the feed back is giving a thumbs up.
The upload script is PHP a stripped down version of the image upload script in the forum sticky post.
[code=php]// first let’s set some variables
// make a note of the current working directory, relative to root.
$directory_self = str_replace(basename($_SERVER[‘PHP_SELF’]), ”, $_SERVER[‘PHP_SELF’]);
// make a note of the directory that will recieve the uploaded file
$uploadsDirectory = $_SERVER[‘DOCUMENT_ROOT’] . $directory_self . ‘media/’;
// fieldname used within the file <input> of the HTML form
$fieldname = “contentSelect”;
$uploadForm = “AVLan”;
// possible PHP upload errors
$errors = array(1 => ‘php.ini max file size exceeded’, 2 => ‘html form max file size exceeded’, 3 => ‘file upload was only partial’, 4 => ‘no file was attached’, 5 => ‘mime type not supported’);
// check the upload form was actually submitted else print the form
isset($_POST[‘submit’]) or error(‘the upload form is needed’, $uploadForm);
// mime check
$allowedMime = array(‘image/jpg’, ‘image/jpeg’, ‘image/png’, ‘image/gif’, ‘audio/mpeg’, ‘audio/mp4’, ‘audio/wav’, ‘audio/ogg’);
(!in_array($_FILES[‘uploadedFile’][‘type’], $allowedMime)) or error($errors[5], $uploadForm);
// check for PHP’s built-in uploading errors
($_FILES[$fieldname][‘error’] == 0)
or error($errors[$_FILES[$fieldname][‘error’]], $uploadForm);
// check that the file we are working on really was the subject of an HTTP upload
@is_uploaded_file($_FILES[$fieldname][‘tmp_name’])
or error(‘not an HTTP upload’, $uploadForm);
// If its an image, test it to get the image size.
if(in_array(array($_FILES[‘uploadedFile’][‘type’],array(‘image/jpg’, ‘image/jpeg’, ‘image/png’, ‘image/gif’)))) @getimagesize($_FILES[$fieldname][‘tmp_name’]) or error(‘only image uploads are allowed’, $uploadForm);
$uploadFilename = $_FILES[$fieldname][‘name’];
// now let’s move the file to its final location and allocate the new filename to it
@move_uploaded_file($_FILES[$fieldname][‘tmp_name’], $uploadFilename)
or error(‘receiving directory insuffiecient permission’, $uploadForm);
//echo $uploadFilename; <– this is what I put in to echo back some information, its commented out at present
// The following function is an error handler which is used
// to output an HTML error page if the file upload fails
function error($error, $location, $seconds = 5)
{
header(“Refresh: $seconds; URL=”$location””);
echo ‘<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01//EN”‘.”n”.
‘”http://www.w3.org/TR/html4/strict.dtd”>’.”nn”.
‘<html lang=”en”>’.”n”.
‘ <head>’.”n”.
‘ <meta http-equiv=”content-type” content=”text/html; charset=iso-8859-1″>’.”nn”.
‘ <link rel=”stylesheet” type=”text/css” href=”stylesheet.css”>’.”nn”.
‘ <title>Upload error</title>’.”nn”.
‘ </head>’.”nn”.
‘ <body>’.”nn”.
‘ <div id=”Upload”>’.”nn”.
‘ <h1>Upload failure</h1>’.”nn”.
‘ <p>An error has occured: ‘.”nn”.
‘ <span class=”red”>’ . $error . ‘…</span>’.”nn”.
‘ The upload form is reloading</p>’.”nn”.
‘ </div>’.”nn”.
‘</html>’;
exit;
} // end error handler
Any ideas on how I cure this because when the script is used in the conventional way, the upload page submits to an upload.php script I get no problems and the file uploads and appears in the intended directory.
I really don’t see why a multipart/form-data conventional form will upload where as an AJAX based form using the same multipart/form-data would produce the error.
