Upload image to remote server from localhost

Recommended Posts

I found a good script that uploads an image but but I want to integrate it in another script and I can't do it because it has two files and it needs a user to make it wok, the first sends the image to the second that uploads and renames the image but even if they are joined the page is reloaded. I want to make them work as one, to take image from a variable, upload the image to the remote server and return the image address.

The form

<?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']);
// make a note of the location of the upload handler
$uploadHandler = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.processor.php';
// set a max file size for the html upload form
$max_file_size = 200000; // size in bytes
// now echo the html page ?>
<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>

 

The uploader

<?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']);

// make a note of the directory that will recieve the uploaded files
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'uploaded_files/';

// 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';
// make a note of the location of the success page
$uploadSuccess = 'http://' . $_SERVER['HTTP_HOST'] . $directory_self . 'upload.success.php';
// name of the fieldname used for the file in 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');

// check the upload form was actually submitted else print form
isset($_POST['submit'])
or error('the upload form is neaded', $uploadForm);
// check for standard uploading errors
($_FILES[$fieldname]['error'] == 0)
or error($errors[$_FILES[$fieldname]['error']], $uploadForm);

// check that the file we are working on really was an HTTP upload
@is_uploaded_file($_FILES[$fieldname]['tmp_name'])
or error('not an HTTP upload', $uploadForm);

// validation... since this is an image upload script we 
// should run a check to make sure the upload is 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 taken... if it is keep trying until we find a vacant one
$now = time();
while(file_exists($uploadFilename = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name']))
{
$now++;
}
// now let's move the file to its final and allocate it with the new filename
@move_uploaded_file($_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 the success page.
echo 'Image address<br>';
echo $uploadFilename;
//header('Location: ' . $uploadSuccess);

// make an error handler which will be used if the upload fails
function error($error, $location, $seconds = 10)
{
header("Refresh: $seconds; URL=\"$location\"");
echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"'."\n".
'"http://www.w3.org/TR/html4/strict.dtd">'."\n\n".
'<html lang="en">'."\n".
'	<head>'."\n".
'		<meta http-equiv="content-type" content="text/html; charset=iso-8859-1">'."\n\n".
'		<link rel="stylesheet" type="text/css" href="stylesheet.css">'."\n\n".
'	<title>Upload error</title>'."\n\n".
'	</head>'."\n\n".
'	<body>'."\n\n".
'	<div id="Upload">'."\n\n".	<h1>Upload failure</h1>'."\n\n".
'		<p>An error has occured: '."\n\n".
'		<span class="red">' . $error . '...</span>'."\n\n".
'	 	The upload form is reloading</p>'."\n\n".
'	 </div>'."\n\n".
'</html>';
exit;
} // end error handler
?>

The main problem is how the form is sending the image

 

I think that you can upload without reloading the page with functions. But I don't know how to send the images to the upload.processor because I don't know how the form sends the file

 

<form id="Upload" action="<?php echo $uploadHandler ?>" enctype="multipart/form-data" method="post">
<label for="file">File to upload:</label><input id="file" type="file" name="file">
