how to uplad a file to the server

otuatail · April 15, 2009

Hi I have been trying to uplad a fiel to the server. I weas pointed in the direction of code to use but I am getting errors.

Fatal error: Call to undefined function error() in /home/fhlinux190/d/des-otoole.co.uk/user/htdocs/ftp/upload.processor.php on line 33

($_FILES[$fieldname]['error'] == 0) or error($errors[$_FILES[$fieldname]['error']], $uploadForm);

This is what I was given.

<?php

// filename: upload.form.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']), '', $_SERVER['PHP_SELF']);
//echo("Current basename dir = " . basename($_SERVER['PHP_SELF']) . "<br>"); // = upload.form.php
//echo("Current basename+ dir = " . $_SERVER['PHP_SELF'] . "<br>");  // = /ftp/upload.form.php
//echo("Current working dir = " . $directory_self . "<br>"); // = /ftp/
//echo("directory_self = " . $directory_self . "<br>"); // = /ftp/


// make a note of the location of the upload handler script
$uploadHandler = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.processor.php';
//echo("upload handler scriptr=". $uploadHandler . "<br>"); // =http://www.des-otoole.co.uk/ftp/upload.processor.php

// set a max file size for the html upload form
$max_file_size = 30000; // size in bytes

// now echo the html page
?>
<!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">
        <link rel="stylesheet" type="text/css" href="stylesheet.css">
        <title>Upload form</title>
    </head>
    <body>
    <form id="Upload" action="<?php echo $uploadHandler ?>" enctype="multipart/form-data" method="post">
        <h1>
            Upload form
        </h1>
        <p>
            <input type="hidden" name="MAX_FILE_SIZE" value="<?php echo $max_file_size ?>">
        </p>
        <p>
            <label for="file">File to upload:</label>
            <input id="file" type="file" name="file">
        </p>

        <p>
            <label for="submit">Press to...</label>
            <input id="submit" type="submit" name="submit" value="Upload me!">
        </p>
    </form>
    </body>
</html>

and the upload form is.

<?php
// filename: upload.processor.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']);  // = /ftp/
// echo("Current working dir=". $directory_self . "<br>");
// make a note of the directory that will recieve the uploaded file
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'uploaded_files/';
// echo("Upload dir=". $uploadsDirectory . "<br>");
// make a note of the location of the upload form in case we need it
$uploadForm = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.form.php';
// echo("Upload dir=". $uploadForm . "<br>");
// make a note of the location of the success page
$uploadSuccess = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.success.php';

// fieldname used within the file <input> of the HTML form
$fieldname = 'file';

// Now let's deal with the upload

// 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');

echo ("uploadform = " . $uploadForm);

// check the upload form was actually submitted else print the form
isset($_POST['submit']) or error('the upload form is neaded', $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);
// echo("tmp_name=" . $_FILES[$fieldname]['name']);
// validation... since this is an image upload script we should run a check
// to make sure the uploaded file is in fact an image. Here is a simple check:
// getimagesize() returns false if the file tested is not an image.
@getimagesize($_FILES[$fieldname]['tmp_name']) or error('only image uploads are allowed', $uploadForm);

// make a unique filename for the uploaded file and check it is not already
// taken... if it is already taken keep trying until we find a vacant one
// sample filename: 1140732936-filename.jpg
$now = time();
while(file_exists($uploadFilename = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name']))
{
    $now++;
}
$uploadFilename = $uploadsDirectory . $_FILES[$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);


// If you got this far, everything has worked and the file has been successfully saved.
// We are now going to redirect the client to a success page.
header('Location: ' . $uploadSuccess);
// The following function is an error handler which is used
// to output an HTML error page if the file upload fails
