<h1>Upload A File, Man!</h1>
<form enctype="multipart/form-data" action="<?php print $_SERVER['PHP_SELF'] ?>" method="post">

<?php
require 'config.php';
require 'functions.php';
if(isset($_FILES['fupload'])) {
if(preg_match('/[.](jpg)|(gif)|(png)$/', $_FILES['fupload']['name'])) {
$path_to_image_directory='images/';
$filename = $_FILES['fupload']['name'];
$source = $_FILES['fupload']['tmp_name'];
$target = $path_to_image_directory . $filename;
move_uploaded_file($source, $target);
createThumbnail($filename );
}
}
?>
这是我的拇指创建功能
and here is my function for thumb creation
<?php function createThumbnail($filename) {
require 'config.php';
if(preg_match('/[.](jpg)$/', $filename)) {
$im = imagecreatefromjpeg($path_to_image_directory . $filename);
} else if (preg_match('/[.](gif)$/', $filename)) {
$im = imagecreatefromgif($path_to_image_directory . $filename);
} else if (preg_match('/[.](png)$/', $filename)) {
$im = imagecreatefrompng($path_to_image_directory . $filename);
}
$ox = imagesx($im);
$oy = imagesy($im);
// $nx = $final_width_of_image;
$final_width_of_image='100px';
$nx = $final_width_of_image;
$ny = floor($oy * ($final_width_of_image / $ox));
$nm = imagecreatetruecolor($nx, $ny);
imagecopyresized($nm, $im, 0,0,0,0,$nx,$ny,$ox,$oy);
$path_to_thumbs_directory='thumbs/';
if(!file_exists($path_to_thumbs_directory)) {
if(!mkdir($path_to_thumbs_directory)) {
die("There was a problem. Please try again!");
}
}
imagejpeg($nm, $path_to_thumbs_directory . $filename);
$tn = '<img src="' . $path_to_thumbs_directory . $filename . '" alt="image" />';
$tn .= '<br />Congratulations. Your file has been successfully uploaded, and a thumbnail has been created.';
echo $tn;
} ?>
这是我创建图像缩略图的代码
图像存储到文件夹中，但未创建thmb，但显示成功创建拇指的成功消息
因此，任何人都可以检查代码并得到错误信息
感谢您的提前帮助
很抱歉，如果不清楚的话

So,please can any one check the code and get me the error
Thanks for help in advance
Sorry if it is not clear
